The rubber grommet has a channel on the inside. This channel is designed to allow the rubber grommet to fit onto and around the factory flared end. Use WD or soap-and-water to help the flare with the rubber grommet seat properly into the top of the operator unit receiver.
See Figure , View B. Use the screws supplied with the kit to secure the compression ring with return to the operator unit. Spray a tube seal from the tube kit with WD or soap-and-water. Attach the upper, field-flared end of the straight tube to the radius bend using the tube seal and cast clamps provided in the tube kit. Use a trim collar at the ceiling. Spraying the tube seal with WD or soap-and-water helps to prevent pinching the tube seal and possible leaks in the joint.
This step is critical and must be done on every joint in a steel tube run. The dual-sided operator unit has two operator control panels. One of the control panels is equipped with a power switch. A filler plug replaces the power switch on the other control panel. If you are installing the dual-sided operator unit in a situation where it will be accessed from one side only, verify that the dual-sided operator unit is oriented so that the side with the power switch faces the operator.
Failure to observe this guideline will inconvenience the operator and the service technician. Remove the two screws which mount the top cover of the dual-sided operator unit to the tube bracket, and remove the top cover. Set these pieces aside. Determine the required length for the straight length of painted steel tubing that will extend from the tube bracket assembly of the operator unit to the radius bend.
Flare the end of the tube that will be connected to the radius bend. Slide the top cover of the dual-sided operator unit over the factory-flared end of the straight tube. Be careful not to scratch the painted tubing. Verify the top cover is properly oriented to slide down into position on the operator unit after you make the tubing connection.
Spray a tube seal from the dual-sided operator unit tube kit with WD or soap-and-water. Use the tube seal and cast clamps from the dual-sided operator unit tube kit to connect the tubing of the dual-sided operator unit to the factory-flared end of straight tube. Verify the cast clamps are oriented as shown in Figure , View A when you connect the tubing of the dual-sided operator unit to the factory-flared end of straight tube. The ends of the cast clamps should be oriented towards the front and the back of the dual-sided operator unit.
If the cast clamps are oriented towards the sides of the dual-sided operator unit, the top cover will not fit down over the tube bracket assembly. Use the tube seal and cast clamps provided in the tube kit to attach the upper end of the straight tube to the radius bend.
The counter-mounted unit requires clear plastic tubing between the operator unit and the radius bend. A line item on the sales order specifies the appropriate tubing kit part number for this configuration.
The procedure required to install tubing for the counter-mounted standard operator unit is similar to that required to install the tubing at the customer unit Section 5. Install a countertop mounting kit A to connect the terminal to the countertop. Included with this kit is a rubber plug that you install between the terminal and the countertop. The rubber plug serves two purposes: it enables you to position the unit onto the counter, and it acts as a sound suppressor during system operation.
See Figure for an illustration. Perform the following procedure to install the tubing for a counter-mounted standard operator unit.
Remove the compression ring with return Figure , View B bolted to the top of the operator unit and set it aside. The compression ring with return will not be used. Determine the required length for the straight length of clear plastic tubing. When you measure, make sure to add 1 inch 25 mm to allow for the recessed area located at the top of the operator unit.
Cut the tubing to the required length. Do NOT cut from the factory-beveled end marked by the red arrow. Check for squareness, and bevel. See Figure , View D for bevel detail. With the red arrow pointing down, install the flat plastic compression ring Figure , View C supplied with the kit and O-ring supplied with the kit over the plastic tubing. Position the tube in the recess on top of the operator unit.
Carefully slide the O-ring and compression ring down until they join the operator unit. The O-ring should rest on the lip of the recess. Tuck the O-ring down into the operator unit receiver around the tubing. Attach the upper end of the clear plastic tubing to the radius bend using the rubber sleeve and metal band clamp provided with the tubing kit. To avoid over tightening of the metal band clamp, observe the following guidelines:.
Tighten the two nuts only until the clear tubing cannot move. Using your hands to apply sideways motion, try to twist the clear plastic tubing.
If the tubing moves, tighten the nuts a little more. Repeat this step until the clear plastic tubing does not twist. The carrier should pass through this connection without hesitation or getting stuck in the joint.
If the carrier slows down or gets stuck at this point, the metal band clamp is too tight and the tubing is now teardrop- or oval-shaped. To correct the misshapen tubing, loosen the metal band clamp, rotate the band clamp 45 degrees left or right from the original position, and repeat the steps to tighten the band. Use a trim collar Figure , View C for the tubing and electrical conduit at the ceiling.
The outer diameter of the steel tubing is less than the outer diameter of the clear plastic tubing. The part of the rubber sleeve with the narrower inner diameter goes over the steel tubing. The flare lip of the steel tubing seats in the groove inside the rubber sleeve. The part of the rubber sleeve with the wider inner diameter goes over the clear plastic tubing.
Perform the following procedure to mount and install the tubing for a counter-mounted, dual-sided operator unit. See Figure for installation drawings. Place the rubber mounting pad under the base of the operator unit. Properly align the rubber mounting pad with the operator unit. Cut the straight length of tubing to the required length according to the requirements previous step.
If you are installing the dual-sided operator unit in a situation where it will be accessed from one side only, orient the dual-sided operator unit so that the control panels are oriented so that the control panel with the power switch faces the operator. See Figure Spray a tube seal with WD or soap-and-water.
Use a tube seal and cast clamps to connect the tubing of the dual-sided operator unit to the factory-flared end of straight tube. Verify the cast clamps are oriented properly when you connect the tubing of the dual-sided operator unit to the factory-flared end of straight tube.
Use the tube seal and cast clamps to attach the upper end of the straight tube to the radius bend. Use a trim collar for the tubing and electrical conduit at the ceiling. Install wood screws through the base of the operator unit and the rubber mounting pad to mount the operator unit to the countertop Figure Reinstall the bottom housing assemblies.
Observe the following guidelines for applying the operator unit and carrier labels from the lane ID kit:. Standard operator unit - Apply one operator unit label to the control panel, as shown in Figure , View A.
Dual-sided operator unit - Center and apply one operator unit label to the clear tube sleeve, just above the black seal, as shown in Figure , View B. See Section 5. There are four mounting holes in the base of the unit. Observe the following guidelines when you anchor the unit:. Fill the space above the anchor bolts with caulking. Then install four black dome plugs, supplied with the system, in the bolt recesses.
The caulking helps to protect the anchors and adheres the hole plugs in place. Do not put the Kwik bolts into the concrete until the clear plastic tubing is installed. Since the plastic tubing is recessed, first move the customer unit so that you can place the plastic tube in the top of the terminal.
Then move the customer unit and tube under the air radius so that this assembly can be connected to the radius. The truck and van base kit G00N is installed to raise the customer unit 8 inches mm. The customer unit is bolted to the base assembly Figure , and the base assembly is anchored to the island. The required hardware is shipped with the kit.
The base assembly is charcoal grey. Regardless of the configuration, clear plastic tubing is usually installed between the radius bend and the customer unit. When you measure, make sure to add 1 inch 25 mm to allow for the recessed area located at the top of the customer unit.
See Figure , View A for bevel detail. With the red arrow pointing down, position the O-ring beneath the compression ring and place this assembly over the tubing. Slide the assembly down into the recess on top of the customer unit. Carefully slide the O-ring and compression ring down until they join the customer unit.
See Figure , View C. Using your hands to apply sideways motion , try to twist the clear plastic tubing. If the tubing moves tighten the nuts a little more. The outer diameter of the PVC radius bend is less than the outer diameter of the clear plastic tubing. The part of the rubber sleeve with the narrower inner diameter goes over the end of the PVC radius bend.
The outer diameter of the steel radius bend is less than the outer diameter of the clear plastic tubing. The part of the rubber sleeve with the narrower inner diameter goes over the end of the steel radius bend.
The flare lip of the steel radius bend seats in the groove inside the rubber sleeve. The steel offset tubing kit A Figure is an alternate way of connecting the customer unit to the air radius bend. The steel offset tubing piece supplied in the kit provides an 8-inch mm offset so that the tubing connection can miss a beam or other obstruction in the canopy. The steel offset tubing kit may be an alternative to a field-fabricated offset Section B.
The connections for the steel offset tubing at the customer unit and the air radius bend are identical to the tubing connections for the suspended operator unit. The kit includes the rubber grommet and the compression ring cast metal ring with return for steel tubing used at the connection to the customer unit.
If the system uses the optional large capacity carrier, install the large capacity carrier kit E. These instructions are provided with the kit. Apply the customer unit label from the lane ID kit on the customer unit. See Figure for suggested locations. Choose the location that provides the best view for the operator.
The blowers used with VAT 21GX are shipped with the system and are designed to be installed in a canopy. To prevent damage, do NOT lift the blower assembly using the spring-loaded valve assembly at the rear of the unit. Unlike previous models of the blower assembly, the blower assemblies listed in Table may be mounted vertically as well as horizontally. Additionally, these blower assemblies are equipped with a spring-operated air valve that replaces the old-style flap valve cover.
Observe the following guidelines when you install the blower packages Figure :. Hole flanges are provided along the sides of the blower housing. These holes are used to secure the blower assembly to unistrut or another rigid structure inside the canopy.
Observe the following guidelines as you mount the blower assemblies:. If the blower assembly wobbles during operation, confirm that this movement does not interfere with the operation of other assemblies. As the blower assembly sways back-and-forth or side-to-side, confirm that this action does not cause the flex hose to loosen and fall off the air radius bend or pull the flex hose from the blower. The blower assembly ships with the junction box installed.
Orient the blower assembly junction box towards or down toward the service access panels. Do NOT mount the blowers inside the building.
The blowers create less noise disturbance and are more accessible for service if they are mounted in the canopy. If the blower package is located beneath the canopy, set the blower package so that when rain falls at a degree angle, the rain will not directly strike any part of the blower package.
Refer to Figure for an illustration showing additional blower mounting details. Use flex hose and clamps to attach each blower to a port on the air radius bend.
Observe the following guidelines when you install the flex hose:. The flex tubing kit included in the standard installation tube kit contains one foot long 8 m flex hose and four stainless steel hose clamps. Maintain some slack in the flex hose to prevent the hose from loosening from the clamp. For plenum approved installations, replace the flex hose kit with the plenum kit B.
It is always best to install the blower as close as possible to the air radius bend in order to minimize air flow loss. Use 3-inch ID PVC pipe as an alternative to the flex hose when the blower is located a relatively long distance from the air radius bend. The maximum distance from the blower to the air radius bend is feet 30 m.
If you use PVC tubing, install flex hose for the transition from the end of the PVC tubing to the port on the air radius bend. Secure the flex hose to the tubing or joists with duct tape or with inch mm cable ties at intervals of three to four feet to mm. Securing the flex hose helps to minimize wear caused by the movement of the flex hose. This section provides the information needed to connect the interconnect cable between the customer unit, operator unit, blowers, customer interface CCA, and control box.
The installer must be trained and experienced in the installation of complex electrical-mechanical devices. To avoid damage to components, observe proper electrostatic discharge ESD precautions.
Use a properly-grounded, anti-static wrist strap or work surface whenever handling CCAs. Use an anti-static carrier to store CCAs before installation and after removal. For domestic USA installations, the electrical contractor will provide three VAC, 60 Hz, 15 amp power outlets to the control box, operator unit blower, and customer unit blower. One power outlet is required for each system control box.
Due to the size of the transformers, the power outlets must be spaced at least 4inches mm apart horizontally and at least 6 inches mm apart vertically.
Failure to observe this guideline may cause a blown fuse or cause the VAT 21GX system to malfunction. One amp dedicated branch circuit is required per lane for the blower packages. A foot 3 m long section of painted, thin wall conduit is included with the installation package that ships with the system. The installer must measure, cut, deburr, and attach the painted electrical conduit to the top of the customer and operator units. Use a round file or deburring tool A to deburr the conduit.
Deburring the conduit is necessary to prevent damage to the cables. To prevent severe personal injury or death from electric shock, verify that all electrical power to the VAT 21 system is disconnected before you perform procedures in this section. See Table for information about the interconnect cabling to install between each VAT device. See Figure for a typical field-installed cabling diagram with Audio.
The information in this section applies to USA domestic installations only. The control box and the electrical requirements are different for international installations. A copy of these instructions ship with each control box. Use the bottom of the control box as a template to mark the location of the mounting screws locally obtained. Allow sufficient cable, properly bundled with wire ties, for a 6-foot 1.
When service is needed, the service loop enhances the serviceability of components. See Figure for cable requirements.
Diebold suggests that you remove the control logic CCA from the control box to connect the wiring. You may damage the terminal strip and have to replace the control logic CCA if you use a screwdriver that is too large for the terminal strip screws. When you replace the cover on the control box, verify the proper orientation of the cover. Proper orientation of the cover permits access to blower timer pots R14 and R15 on the control box CCA. See Figure for the correct way to route the cables inside the customer and operator units.
Use cable tie straps to secure the VAT interconnect cable to the wire guard at the top middle and at the tab on the upper right corner. Pull sufficient cable through the electrical conduit to create a inch 25 mm service loop. Normally, when a customer arrives at the customer unit, the customer unit door is open and the carrier is already present for the customer.
In this instance, the customer may initiate the transaction by removing the carrier from the customer unit. The operator may use the audio system to verbally acknowledge or greet the customer. In certain cases, the customer may press the CALL button to talk to the operator prior to starting the transaction procedure.
The customer inserts the transaction material into the carrier and returns the carrier to the customer unit. The customer then presses the SEND button and the carrier is sent to the operator unit.
When the carrier arrives at the operator unit, the operator unit door opens to allow the operator to remove the carrier. After processing the transaction, the operator places all transaction material inside the carrier. The operator then places the carrier into the operator unit and presses the SEND button to return the carrier to the customer. When the carrier arrives at the customer unit, the door opens to allow the customer to remove the carrier.
After removing the transaction material from the carrier, the customer returns the carrier to the customer unit. In most instances, the transaction is complete and the customer departs. The carrier remains in the customer unit and the customer unit door remains open.
The system is ready to receive the next customer. If the customer wishes to talk to the operator at any time during the transaction procedure, the customer presses the CALL button located on the customer unit control panel.
When the CALL button is pressed, an audible signal is generated to alert the operator. See Table for a description of some the situations that may occur when you or a customer operate the system.
Table also provides appropriate procedures to recover the carrier. Do not spray VAT21 units with a pressure washer or water from a hose.
Failure to observe this guideline may damage the VAT21 units and cause system malfunction. If necessary, use Graffiti Terminator Remover from Genesis Coatings to remove stains such as permanent marker, ink, lipstick, or paint.
Wash the clear acrylic door and clear tubing with mild soap or detergent, with plenty of lukewarm water. Dry with a soft cloth or chamois. If necessary, use hexane or kerosene to remove grease, oil, or tar. Wash immediately to remove solvent residue. Hexane and kerosene are volatile, flammable substances. Use in a well-ventilated area away from other flammable substances or ignition sources. Use these substances with care to prevent severe personal injury and damage to the equipment.
Avoid breathing vapors. Avoid skin contact. Keep these substances away from eyes and other body parts, clothing, and so on. Store these substances in a proper place and in a proper, labeled container.
Do not use window cleaning sprays, scouring compounds, acetone, gasoline, benzene, carbon tetrachloride, or lacquer thinner on the clear acrylic door. Failure to observe this guideline may result in haziness, scratching, or abrasion of the clear acrylic material. If a customer requests an item such as a pen, have the customer place the carrier in the customer unit and push the SEND button.
When returning the carrier, it is good practice to remind the customer to place everything in the carrier with the transaction. This test is used to test operation of the rotary solenoid and to verify the operation of the flapper valve in the customer unit. The customer unit air valve solenoid remains on for 10 seconds. Press and hold the STEP button to exit this test before the second period expires. This test is used to check inputs to the customer unit control board.
The LCD on the customer unit control board indicates testing results. When this test is selected, the system reads the initial switch inputs, and uses this initial reading as a baseline.
Whenever an input changes after the initial reading, the LCD displays the hexadecimal code 0-F of the switch. LED indicators on the customer unit control board indicate an active switch or input. When the LED is lit, it indicates that the switch or input is operating and is input to the control board processor.
The proper hexadecimal code on the LCD indicates that the control board processor recognizes the switch or input. If you accidently select and execute this test, press and hold the STEP button to exit the test. This test is used to check the part number of the firmware. The LCD on the customer unit control board displays the part number.
Use this test to verify the type of operator terminal that is currently operating. The LCD on the customer unit control board indicates either OH to represent an upsend operator terminal, or UG to represent a downsend operator terminal. Make a note of which other LEDs on the operator control panel are also flashing. Refer to Table B-3 for information about what you should do. During the first few seconds of an error routine, the system will attempt to resolve the problem automatically.
If the system is unable to resolve the problem, the system functions in one of the following ways:. The LEDs continue flashing, and the system ignores all pressing of customer terminal or operator terminal buttons. Ideally, the horizontal portion of the tubing is a straight run with no bends. When bends are required, this appendix provides information about fabricating and using partials and offsets. The information in this appendix applies to steel tubing. A partial is the part of a degree radius bend used to change the angle of the direction that the tubing is running.
To calculate the length of a partial, you may have to measure an angle and convert this measured angle to a number of inches. The following steps describe this procedure. See Table C-1 to determine the length that corresponds to the angle you measured in Step 1. To find the tangent point, place a straight edge on the outside of the degree radius bend Figure C-1, View A.
Mark the point tangent where the bend begins. Starting at the tangent point, measure the length you computed in Step 2 along the outside of the degree radius bend. Mark the spot to show where to cut the tubing, and mark the cut line.
See Figure C-1, View B. Assume that you require a degree angle for the partial. Measure 8inches mm from the tangent point, along the outside of the radius bend and mark the tubing at this spot.
This is where to cut the tubing. See Figure C-1, View B for an illustration. Construct the partial. See Figure C-1, View C for an illustration.
If you need to make a perfect partial, you must start with a perfect degree radius bend. See Table C-1 to find the length to measure along the outside of radius bend. Starting from a tangent point, measure and mark this length along the outside of the degree radius bend.
Fabricate an offset Figure C-2, View A when it is necessary for a vertical or horizontal tube run to get past an obstruction while remaining on the same plane. Construct an offset by cutting two equal lengths from a degree radius bend. Then flare the two pieces and join them to form an S-curve adding a straight length of tubing in between if necessary. Determine the position of the cuts by the size of the offset needed to bypass the obstruction. If you need to make a perfect offset, you must start with a perfect degree radius bend.
Measure the offset distance Figure C-2, View A. You can measure at a degree angle from the right side of the tubing on the current path, to the right side of the tubing on the proposed path.
Place a straight edge along the outside of one end of the degree radius bend and mark the point tangent where the bend begins Figure C-2, View B. Perform this same procedure on the other end of the bend. Perform the following steps to measure for the offset. See Table C-2 to determine the length that corresponds to the offset distance you measured in Step 1.
Measure this length from one of the tangent points of the degree radius bend, along the outside of the degree radius bend. Measure the same length from the other tangent point of the degree radius bend. Cut from both ends of a single degree radius bend and add a straight section to form the offset. Mark spots to show where to cut the tubing, and mark the cut lines.
Cut the tubing at the cut lines you marked in Step 3 or Step 4. Flare the ends of the tubing as required. Connect the tubing by using cast clamps and seals to form the offset or S-curve. If you need a 4-inch mm offset, Table C-2 shows the length to be 10 inches mm.
Perform this same procedure at the other end of the degree radius bend. Cut the degree radius bend at the required cut line to get the correct pieces needed to fabricate the offset. Multiply this number by 2. Cut the degree radius bend at the cut lines, and cut the piece of straight tubing at the cut lines to get the correct pieces needed to fabricate the offset. See Table C-2 to find the length to measure along the outside of the degree radius bend.
Starting from a tangent point, use a flexible tape measure and mark this length along the outside of the degree radius bend. Starting from the other tangent point, use a flexible tape measure and mark the same length along the outside of the degree radius bend. Turn off the building power breakers for the customer unit circuit prior to doing any installation work.
Make sure that the customer unit power supply breaker is off. Remove the cast metal ring and the O-ring from the top of the customer unit. Measure to determine the required length of clear, plastic tubing. Make sure you allow for the recess of the customer unit. Do not cut from the factory-beveled end. Bevel the cut end. Position the O-ring beneath the cast metal ring, and slide this assembly onto the plastic tubing. Use the rubber sleeve and the metal band supplied with the kit to attach the top of the plastic tube to the tubing that extends from the radius bend.
Install a rubber seal on the uncut end of the PVC bell piece. Roll the seal back over itself. Verify that you connected the two-wire pair between the tube switch and the overhead customer unit. Observe where these connections were made. Verify that the electrical contractor connected the customer unit power supply assembly wiring to the VAC amp circuit supplied to the junction box.
Verify that the overhead tubing is installed. This tubing should have a flared radius bend above the location for the operator unit. Standard operator unit: Remove the cast metal ring and rubber grommet bolted to the top of the operator unit, and set these pieces aside.
Dual-sided operator unit: If installed, remove the coupling and tube seal attached to the top of the operator unit, and set these pieces aside. Turn off the building power breakers, and if installed, also verify the customer unit power supply breaker is off. Measure the length for the straight painted tubing with the flared end. This tubing extends from the radius bend to the operator unit.
Cut the excess tubing from the straight end to the required length. Make sure that you retain the flared end. Standard operator unit: Slide the cast metal ring standard unit down onto the rubber grommet. Dual-sided operator unit: Loosely fit the coupling over the tube seal. Standard operator unit: Place the factory-flared end of the tubing into the recess in the operator unit.
Dual-sided operator unit: Butt the factory-flared end of the tubing against the factory flare of the operator unit. Standard operator unit: Carefully slide the cast metal ring down the tubing onto the rubber grommet, and then use the screws supplied with the kit to secure the cast metal ring to the operator unit.
Dual-sided operator unit: Secure the cast coupling and tube seal assembly to join the straight tubing to the factory flare of the operator unit. Use the tube seal and the cast clamps to attach the upper end of the tubing to the radius bend.
NOTE This checklist applies to the installation of the standard operator unit only. Remove the cast metal ring and rubber grommet bolted to the top of the operator unit, and set these pieces aside. Make sure you allow for the recess of the operator unit. Carefully slide the cast metal ring down the tubing onto the rubber grommet, and then use the screws supplied with the kit to secure the cast metal ring to the operator unit.
Attach the upper end of the tubing to the radius bend. Use the tube seal and the cast clamps supplied in the tube support kit. All thread 6ft. Required to stabilize tubing at operator unit. Plastic hanger strap from support strap kit C Strap or clamprequired at both sides of coupling.
