MODEL 2914

the possibility of loss or damage. In order to eliminate the possibility of inconvenience and possible additional expense, we urge that you carefully follow these suggestions: When a shipment is delivered to the carrier their agent receipts for it in good condition. It is securely packed; otherwise, they would not accept it and according to the terms on the Bill of Lading, a legally binding contract, the carrier agrees to deliver it to you in the same perfect condition. If these goods are damaged, they should not be accepted until the carrier's agent has noted on the Freight Bill which he will give you, the nature and extent of the damage. He is required to do this. In the same manner, if any goods are lost in transit, have shortage noted on the Freight Bill by agent. The agent's opinion that carrier is not responsible does not bar your claim. He is required to refer your claim to his Claim Dept.

Concealed Damage: If there should be damage or loss of such a nature that it could not be detected until the goods were unpacked, have the transportation company's agent call AT ONCE and make inspection. Require him to give you a written "Concealed" Bad Order Report, stating the condition of the goods when examined. It is his duty to do this, and you should insist upon it. If he fails to inspect on request, notify by mail within 15 days of delivery and keep a copy of your letter.

We are always willing to handle claims for loss or damage in shipment if the above instructions are complied with. Write us immediately supplying us with an inspection report.

1C. MACHINE DESCRIPTION:

This curtain machine utilizes a single phase capacitor start AC motor, connected to a right angle gear reducer. A double-grooved cable wheel, which is used to operate the curtain track cable, is mounted to the output shaft of the gear reducer. The wheel is NOT driven by the gear reducer output shaft. The wheel is driven via a cast steel driving dog located above the wheel. The driving dog is keyed to the gear reducer’s shaft and powers the drive wheel via a thumb screw threaded through the driving dog and into the drive wheel. IN THE EVENT OF A POWER FAILURE, THE THUMB SCREW CAN BE REMOVED THEREBY FREEING THE WHEEL FROM THE GEAR REDUCER ALLOWING MANUAL OPERATION OF THE TRACK SYSTEM. NOTE THAT POWER MUST BE SHUT OFF AND LOCKED OUT ACCORDING TO OHSA REGULATIONS PRIOR TO ATTEMPTING TO REMOVE THE THUMB SCREW. Track mounted limit switches are furnished with the machine. These switches signal the end of travel for both directions to the machine’s control circuit. A magnetic reversing contactor, control relays, disconnect switch, overload protective breaker and control switches are mounted in or on a sheet steel control enclosure which is remotely located from the track mounted machine.

One (1) three-button remote control station is provided with the machine, additional stations are available upon request. Type TV machines are supplied with 4 button remote control stations to allow for a fast-stop button. The fast-stop button shuts the machine off quickly, bypassing the deceleration ramps of the frequency drive. Depending on what type of remote control is used, single-pole vs double-pole, it may be necessary to reset the relay logic of the machine. To do this, simple press the “STOP” button one time to reset the relays. After doing this, the machine should operate in either direction assuming neither of the limits switches are active. The running speed of type TV machines can be varied by utilizing the speed adjustment knob in the control cabinet. Note that changing the speed of the machine affects the deceleration ramp times. Changing the speed of the machine after the limit switches have been set will require resetting of the limit switches due to the new deceleration ramp times. Changing the parameters of the frequency drives will void the factory warranty. TV Models are supplied with various drive types depending on the application. The drive types are noted on the drives themselves. Identify the drive type then find the correct wiring schematics in the list that follows in the TV section.

13. After exiting the 1409 the cable is threaded through the remaining cable connector of the ma-chine side master carrier. Remove all cable slack from the system. It may be necessary to manually feed the cable around the machine’s wheel in order to remove slack at the machine. After all slack has been removed, tighten the cord connector and trim ex-cess cable.

14. Move the master carrier with the limit tripping dog so that it is between the limit roller yokes as shown on the left. Verify that the limits are installed correctly and that the master carri-er will trip the limits when it passes them. If this is true, move the master to its full closed position (slightly past the limit) and then move the dead-end master to its fully closed position and tighten the ca-ble clamps on the dead-end master carrier.

15. After all the slack has been removed from the system, additional tension is applied to the operating cable by the tension pulley. To apply the additional tension, turn the nut on the pulley shaft clockwise using a 1/2” open end wrench. 16. After cable has been trimmed, rotate drive wheel so that hole in wheel aligns with the thumb screw and secure the wheel to the dog by turning the thumb screw clockwise until it is completely seated.

PROGRAMMING Model “TV” machines are furnished with a wide variety of control circuits and thus the drives are provid-ed with a wide variety of programs. Each machine is furnished programmed with a basic set of parame-ters from the factory. These parameters, as well as the rest of the drive parameters, can be repro-grammed in the field to meet the project specifications. To reprogram the drive please see the manual for the frequency drive controller that was furnished with the machine. Note that depending on the type of drive used, it may be necessary to use a personal computer or user interface module to program the drive. MACHINES EQUIPPED WITH “FAST STOP” LOOPS If the control circuit includes a “Fast Stop” loop in addition to the standard stop loop, the machine will need to be electrically reset after the “Fast Stop” circuit has been activated. Simply press the RESET pushbutton on the machine or remote control to reset the machine after the F-STOP or overtravel limit has been cleared. NOTE: If the machine is equipped with a Model GS-1 drive, it will reset automatically after the fault is cleared. No manual reset is required. TECHNICAL NOTES: Model “TV” machines are equipped with inverter duty motors. Do not replace the motor with a standard duty 3-

phase motor. It is suggested that the machine’s frequency be limited to 60 hertz in order to prevent premature wear of the

machine and track components. If deceleration ramps are used, verify that the machine shuts off prior to the end of the dwell limit cams. If the

limit cams release the limit switch during operation the machine will accelerate and continue to run. The frequency drive is sized according to the horsepower and voltage of the machine’s motor. Do not use a

motor of any other horsepower or voltage. In most cases the frequency drive’s programming section is password protected. A default password is in-

stalled at the factory and can be found in the documentation provided with the machine. It is suggested that the password be changed to a user specific password, once the machine installation is complete.

Not all of the parameters available on the frequency drive can be used with the machine. Verify that the pa-

rameter being changed or added, will work with the machine provided. The machine provides its own control signal. Do not input any outside control voltage or control signal to the

machine.

IMPORTANT: REPROGRAMMING THE FREQUENCY DRIVE UNIT PARAMETERS CAN RESULT IN THE MACHINE OPERATION BEING OUTSIDE OF THE MECHANICAL LIMITS OF THE TRACK OR LIFT SYSTEM. BE SURE TO CHECK POSSIBLE CONFLICTS WITH THE MECHANICAL SYSTEM PRI-OR TO MAKING ANY CHANGES TO THE DRIVE PROGRAM.

MODEL 2914

14. With all of the slack removed from the system, apply tension to the free end of the cable and tighten the screw of the cable connector securing the cable to the master carrier. Trim any excess cable.

15. Rotate the drive wheel back to where the hole in wheel lines up with the thumb screw of the driving dog.

16. With hole in wheel aligned with thumb screw of the driving dog, turn the thumb screw clockwise until the screw completely seats in the drive wheel.

17. Add additional tension to the system by turning the nut of the Tension Pulley clockwise until ample tension is observed. Tension can be increased in the future from this device as well.

Please go to Section 3D on page 16 to install and set the track mounted limit switches.

3C. START-UP:

Limit switches must be installed as illustrated in photo below. Note orientation of the limit switch roller yokes. They MUST be oriented as shown in the picture. Also the master carrier with the tripping arm MUST be placed between the limit switches with its tripping arm extend-ing on the same side of the track as the limit switch rollers.

1. Before applying power, make certain that all track parts are free moving and that, if the output wheel rotates, it will not accidentally engage some nearby object or per son.

2. If the operating cables for the track are connected to the machine, be sure that the

master carriers of the track system are located such that they will be able to move in either direction without binding or causing damage to the system or its surroundings.

3. With power applied, and unit either clear of obstructions or connected to cables in a

manner which will allow free movement, press either the "OPEN" or "CLOSE" pushbutton. The motor should start and the wheel of the machine should rotate. Press ing the "STOP" push-button (red) of the machine should stop all movement. Unit should operate in opposite direction of initial movement when remaining push-button is pressed after machine has stopped. Electrical interlocks prevent reversal while the machine is operating.

4. If the machine appears to be operating normally, and complete installation is to be

done at this time, the limit switches can be adjusted as explained below. Note that during testing of the limit switches, the machine can be stopped at any time by pressing the STOP button of the remote or local control station.

3D. SETTING THE LIMIT SWITCHES (One-way draw systems): 1. The machine is supplied with 2 limit switches, one (1) for the OPEN direction and one (1) for the CLOSED direction. Limit switch control direction is determined by the terminals that the switch is wired to in the control box. (see wiring diagrams that follow) 2. The Master Carrier is equipped with a tripping arm which is used to activate the roller yoke of the limit switches. (Make sure that the master carrier tripping arm extends on

WARNING – LIMIT SWITCHES MUST BE INSTALLED ON TRACK AND WIRED TO THE CONTROL BOX PER WIRING DIAGRAMS LOCATED IN THE BACK OF

MACHINES EQUIPPED WITH FREQUENCY DRIVE CONTROLLERS

MODEL NUMBERS ENDING WITH “TV” DESCRIPTION: Model “TV” machines are fabricated with electronic frequency control modules which allow the user to set various operating parameters for the machine in the field. The machines are fabricated in a variety of styles and use a variety of frequency drive types. Various control circuits are provided with these machines. Basic models offer start/stop/reverse pushbutton operation with analog referenced speed signals. This manual provides an overview of basic machine operation and parts. Please see the drive manual and electrical schematic provided with the machine for information on programming or operating the machine. BASIC INSTALLATION: See machine installation in previous sections. WIRING: NOTE: ALL WIRING TO AND FROM THE MACHINE MUST BE DONE IN ACCORDANCE WITH NA-TIONAL AND LOCAL ELECTRICAL CODES. All field wiring is connected to a barrier type terminal strip located inside of the machine’s control box. The strip(s) positions are labeled. All curtain machines must be grounded. A ground terminal is provided in the control box. Provide a properly sized electrical service for the voltage and current draw of the machine. Though these machines are equipped with 3-phase inverter duty motors, the machine(s) can be fabricated for input voltage sources of; 120 VAC, 220 VAC single phase, 208/220 VAC three phase and 460 VAC three phase. Specifications for the voltage, current, and frequency for the machine can be found on the ADC serial number plate located on the machine’s control box cover. A separate branch circuit for each machine is suggested. In most cases the control circuit is a Class 2 circuit and must be wired accordingly. In most cases the remote control station(s) will operate control relays located in the machine’s control box. Depending on the type of relays used, the control circuit could see a maximum inrush load of 100 VA. If the machine has remotely located speed, fault, indication, etc. controls or indicators please see the manual and schematic provided with the machine for specifications on these circuits.

IMPORTANT: IF THE MACHINE IS EQUIPPED WITH DECELERATION LIMIT SWITCHES AND A DECELER-ATION RAMP, THE MACHINE WILL DECELERATE TO A STOP WHEN THE STOP PUSHBUTTON IS PRESSED AND WILL NOT COME TO IMMEDIATE STOP. THE DECELERATION TIME IS EQUAL TO TIME SET FOR THE DECELERATION RAMPS IN THE DRIVE’S PARAMETERS..

the correct side of the track. See page 4) 3. Move the master carrier until the curtain is in the fully open position. Note that the master will coast approximately 6 to 8 inches after it trips the limit switch so make s ure there is enough travel in the system for the master carrier to coast this much by positioning the OPEN limit switch 8” in front of the fully open position of the curtain. Secure the limit with the mounting bolts provided making sure that the switch and its yoke are positioned as shown on page 4. 4. Next mount the CLOSED limit switch approximately 6 to 8 inches from the dead-end pulley of the track. Secure the limit with the mounting bolts provided making sure that the switch and its yoke are positioned as shown on page 4.

5. Re-secure the drive wheel of the machine to the machine’s drive shaft by aligning the driving dog thumb screw with the hole in the wheel and turning the thumbwheel clockwise until it is fully seated.

6. With the track mounted limits in position and tested, the machine can be run to its full

OPEN and CLOSED positions. 4. MAINTENANCE

4A. LUBRICATION:

Lubricate motor as per instructions on motor nameplate (note most motors do not need to be lubricated.

The gear reducer is factory filled with 600W super cylinder oil. During average service, the reducer can be considered permanently lubricated. If for some reason additional lubricant is required, it can be added by removing the fill bolt on the top of the reducer. Be sure to re-move power prior to performing any maintenance on the machine.

4B. ADJUSTMENTS:

All wire-centered cable stretches and slack must be removed from the system periodically. To remove slack, clamp gripping type pliers to one of the cut ends of cable located at the track master carrier. With the cable end secured, loosen the cable clamp of the master carri-er and pull out the excess slack from the system. With slack removed, re-tighten the master carrier cable clamp. Note: The machine operator for this type of system is designed to produce a significant amount of friction on the operating line. Be sure to check the cable slack both before and after the machine is installed. It may be necessary to work the cable slack out by feeding it around the machine’s drive wheel. This machine is equipped with an adjustable tension pulley to add additional tension to the operating line if needed. Note this device applies tension to an already taught operating ca-ble only. All slack must be removed from the system at the master carrier before this device is adjusted. The device is adjusted by threading the nut of the device’s assembly to move the pulley wheel away from the main drive wheel, thus applying additional tension to the sys-tem.

4C. CLEANING:

With power off, remove debris and foreign objects from vicinity of curtain machine, from be-

tween motor and base, motor and frame, and from vicinity of drum. Low-pressure air or a vacuum cleaner can be used for this purpose.

With power off, remove cover from control enclosure. Remove dust and dirt with low- pres-sure air or vacuum cleaner, being careful not to damage any internal parts. Check and tighten all connections and mounting screws. Replace cover.

5. TROUBLE-SHOOTING:

It is assumed that troubleshooting and repair will be performed by individuals with a basic knowledge of electricity, motor controls, with the ability to follow the wiring diagrams en-closed, and who will take the precautions required when working with exposed electrical con-nections.

In order to perform the procedures listed, basic hand tools plus measuring and indicating equipment are required. A clamp-on type volt-amp-ohmmeter tester with accessories will provide the necessary indication and measurements. Before proceeding with any of the checks listed below, make certain that all connections are tight and any obviously defective or broken parts are replaced. Also make certain that track is operating freely and that cables are in good condition.

When ordering replacement parts for this curtain machine, please give a description of the part and also provide the model number and serial number of the machine.
