Door control power. Door operator control uses a
low voltage permanent magnet DC motor. DC motor
is powered by pulse width modulated power (high
speed switching - 20,000 Hz). Motor responds to
average voltage of high frequency pulses, and not
individual pulses.
Current control. Door operator control has a
current sensing circuit in both open and closed
directions to supply feedback to speed control
circuit. Current sensing circuit regulates door closing
force, and open/stall current caused by a hooked
interlock. Current sensing circuit also guarantees
that door operator control relay contacts do not
break or make when motor armature current is
present—helping to prevent damage to relay
contacts. Motor direction is controlled by reversing
armature connection using a conventional relay
system.
Speed & travel limits. Door operator control selects
speed and travel limits with cam operated
microswitches. These microswitches operate relays
tied into speed direction circuits.
Acceleration & deceleration. Door operator control
has an internal soft-start circuit which regulates
smooth acceleration and deceleration. Soft-start
circuit allows average motor voltage to change
gradually when speeds change.

Troubleshooting & adjusting switches. Door
operator control has two small toggle switches
mounted on common circuit board. TEST/RUN
switch and
O-OFF-C switch are used to signal door opening or
closing from car top during troubleshooting and
adjusting; and to disconnect the door open and close
signals, and de-activate internal shutdown timer.
Auxiliary piloting. Door operator control also has a
Form “C” Open and a Form “C” Closed relay contact
for auxiliary piloting.
Other features. Additional items added to Solid
State door control.
➤
Non-adjustable open current limit set at
5 amps.
➤
Non-adjustable internal shutdown timer
removes power if doors do not open or
close within 20 to 30 seconds after a
direction signal is given. Shutdown
indicated by an illuminated LED 7.
