MOTORIZED CURTAIN TRACK SYSTEM
Operation of the motorized curtain track is a simple procedure. Normally a three-button control
station is provided to operate the curtain machine. The functions are “OPEN,” “CLOSE,” and
“STOP.” In some cases, curtain machine operation may be integrated into push-button panels that
control multiple machines or PLC’s that control the curtain machines and other machinery within
the theatre. Refer to curtain machine manual for specific instructions regarding their use.
The curtain track is equipped with an end stop at the center overlap to stop travel of the curtain in
the "CLOSE" position. The limit switch must be adjusted so that the master carrier does not strike
the end stop during travel. When opening the curtain, the single carriers stack against the double
end pulley as the curtain is opened. The limit switch must be adjusted so that carriers are loosely
spaced at the stacking end. Speed at which the curtain may be opened or closed is dependent on the
curtain machine furnished.
MAINTENANCE INSTRUCTIONS
Periodic, regularly scheduled maintenance inspections are necessary for any mechanical system.
A theatrical curtain track system is no different. It has components that must be regularly inspected,
adjusted, maintained, and replaced. In order to keep your system safe and in good working order,
a regular inspection and maintenance program must be implemented.
The best way to maintain your theatrical curtain track system is by regular use. Each mechanical
device should be cycled a minimum of once each week. This will keep the grease properly
distributed in the bearings and allow the inspector to regularly check for unusual noise or drag in
the system. Plan a few minutes each week during a quiet period to operate each device. Listen for
unusual noise and determine the source if it appears. Do not allow any item to be operated or used
if there is any question as to its safety or integrity. Accidents and injuries can be the result. Most
accidents are the result of lack of training, complacency, and overconfidence. Do not assume
anything.
Follow the schedule outlined below as a minimum maintenance program. Once the operating
personnel has had an opportunity to work with the system during the first year, additional procedures
may be added or adjusted as is necessary depending on your facility requirements.
