Open/Close Operation

Open/Close actuator- ivil! iie font-oiled via two, powered, maintained contacts,ore for diiyi'nq :ii the clockwise direction, and one for driving in the counter-clockwise direction. Power may be removed mid-stroke to position

both AC Hot and AC Common. The fuses will never blow in normal operation — they will be conservatively rated and soldered in place for high reliability.

below 104 degrees F. Subsequently, the motor must be capable of 75% duty cycle. Motors will be split phase, capacitor driven with an at.to :esst thermal sensor, and will provide high starting torque and be totally enclosed within

Lubrication

All rotating power train components will be coated with a multi-purpose grease. Lubricants will be suitable for ambient conditions of -40° F to 150° F. For operation in temperatures between 32° F and -40° F an optional heater and thermostat assembly must be included. Gearing

The powertrain will be comprised of stamped gearing will not be permitted.
