17. CURTAIN OPERATIONAL TEST
The curtain operation must be fully tested after installation to confirm that the limit switches and other curtain components are functioning
properly. It is imperative that this test is performed to assure safe and reliable performance for many years to come.
To test the curtain “up” limit, turn the key at the key switch in the up direction (as noted on the key switch faceplate label). The curtain
should start raising (rolling) up until the “up“ limit automatically stops the direction of operation.
Caution: Be prepared to manually
stop the curtain operation, if the limit switch does not stop the direction of travel automatically. If the “up” limit switch does not
stop the direction of travel at the desired location, reset the “up” limit. Repeat the above steps to test the “down” limit setting. Next,
operate the curtain in either direction of travel. While operating the curtain, observe the curtain counter-torque assembly for proper
operation. The wall guide assembly (No. 2081 curtains only) should operate quietly, and without binding or catching on track splices (if
applicable). The torque arm (No. 2082 curtains only) should operate smoothly. The counter-torque belt must wrap evenly on the drum
while centered (in the groove) under the guide roller. The belt must track inside the roller groove when the curtain is operating up or
down. If the belt does not track properly, ensure the belt tie-off point or curtain system is plumb. Adjust if necessary. After observing and
testing the initial operation of the curtain, operate the curtain several more cycles to confirm proper operation.
Note: The curtain torque
motor is not a continuous duty motor. A thermal overload device will shut down the motor after four minutes (approximately two
cycles of operation). The thermal overload will automatically reset when the motor has cooled.

DIVIDER CURTAIN
MAINTENANCE INSTRUCTIONS
The Model No. 2080 Center-Roll
®
divider curtain is designed to operate for many years without any significant service performed.
Depending upon the usage of the unit, it is recommended that at least an annual inspection be made, at which time the following steps
should be taken:
1.
GENERAL
Make certain the Porter key switch is not substituted and is located within full view (but not beneath) the divider curtain. Check the walls
in close proximity to the curtain for any type of protrusion that may interfere with the raising or lowering of the unit (i.e., new scoreboard,
chinning bars, etc.).
2.
TORQUE MOTOR ASSEMBLY
The electric torque motor is permanently lubricated, maintenance free and designed for long life. The torque motor itself does not require
any type of scheduled inspection. However, the electric cord or other attached components should be inspected for proper alignment,
damage or wear, periodically.
3. WALL GUIDE TRACK AND BRACKET ASSEMBLY (No. 2081 Curtains Only)
Annually inspect the wall guide track and bracket assembly. Inspect the guide track for rigid attachment to wall, and ensuring that all
mounting bolts are tight. Check the wall bracket assembly rollers for excessive wear and hardware for tightness. In addition, check the
spring clamp ring for positive motor attachment.
4. TORQUE ARM ASSEMBLY (No. 2082 Curtains Only)
Inspect the torque arm assembly on an annual basis. Visually inspect the torque arm belt edges for excessive fabric wear, fraying, or cuts.
Observe the operation of the torque arm. Ensure the assembly operates smoothly, and that the belt is centered on guide roller the entire
duration of its operation. Lubricate the torque arm bearings annually with a high temperature bearing grease, or when audible signs of
operation indicate a need for lubrication. In addition, check the spring clamp ring for positive motor attachment.
5. RETRACTABLE CORD REEL ASSEMBLY
The cord reel assembly must be visually inspected annually, paying particular attention to the retracting cord integrity. Inspect the outer
jacket of the cord for cuts, abrasion marks, or other signs of damage. Also, check the electrical connectors for tightness. Ensure the
connector tightly grips the cord. If any problems are noted, replace the suspected components immediately. Failure to replace damaged
electrical components could lead to an electrical short causing damage to equipment and injury to others.
