The G.A.L. Model MOMCTL, Master Operator Medium Speed Control Top, consists of a 1/4 HP, 230 Volt D.C. motor with heavy duty sprocket, chain, belt and sheaves. The power supply requirement is 208 VAC or 230VDC, 500 VA, fused at 3 amps. It is also available for 120 Volts. The power supply rectifier and filter, the open, close and reduced speed nudging 3-pole plug-in type relays, are included with the car top controls mounted on printed circuit board making it an ideal replacement for an existing operator.

The control resistors, cams and contacts and the printed circuit board are housed in a heavy duty steel box mounted horizontally on the operator base. The box cover includes the four sides of the box permitting easy car top access to all equipment. Door speed is adjustable by means of resistor tubes located in the operator box.

The 1/4 HP motor is capable of opening the car and hoistway doors simultaneously at a speed up to 2 feet per second. The closing speed may be reduced to limit the stalled closing force and the closing kinetic energy to the values permitted by the ASME Code. The opening and closing limits of travel are cushioned by four steps of dynamic braking resistors.
