2905TV SILVER SERVICE® curtain machine. 1/2 H.P.
No. 2905-TV curtain motor combines versatility with the power and drum capacity needed to operate large draw curtains. Draw curtain machine with electronic frequency control. The most versatile of the ADC line, these machines provide all of the features of an intermediate draw machine plus user definable variable speed control, acceleration ramps, deceleration ramps, overload protection, low voltage control, emergency stop loops and a host of other features. In addition these machines allow the use of inverter duty 3-phase motors on single phase power sources. Machines are equipped with integral limit switches for deceleration and emergency over-travel, programmable frequency drive units, low-voltage control, and can be operated from any number of remote control stations (except speed adjustment is so equipped). If versatility is a project requirement, the "TV" series of machines are the best option. A Cable Tension Device is included as standard equipment.
Output drums are 8" diameter x 12" long and are grooved for 3/16" wire center cable. Maximum cable travel is 90'. Cable speed is 0 to 72 fpm.
Guard (ME-1) not shown. Required for ETL compliance.
Draw curtain machines and drapery motors cannot be used for lifting, since they are not designed for an overhung type of load.
ROTARY LIMIT SWITCHES
Allow for user definable preset stops for the "Full Close" and "Full Open" pre-set positions.
MAGNETIC CONTROL
Provides Start/Stop/Reverse control of the machine. Compatible with most automation systems. LVCS Low Voltage Control 24 VAC standard.
DISCONNECT SWITCH
Toggle switch which removes power to machine’s internal circuitry.
GROOVED CABLE DRUM
Assures positive drive without cable slippage. Coated wire-center cable must be used. Drum must be at least 14' from track live-end pulley, or last pulley in system to allow cable to wind properly on drum.
CABLE TENSION DEVICE
Automatically helps eliminate cable slack. Also helps retain cable within grooves of drum.
EMERGENCY HAND CRANK
Facilitates hand operation of curtain in case of mechanical or power failure.
CONTROL SWITCHES
Three-button type and marked Open, Close and Stop. No limit to number of control stations that can be used. Two supplied with each machine, one built on the machine and one to use as a remote control station.
