10.1.3 Standard operation
Upon a legitimate activation signal the door
accelerates up to open speed, monitoring the current load on
the drive output. (If the current reaches a level above the set
datum the door will stop and close). The door travels at the
set speed (Potentiometer setting) until it reaches the set back
check position, where the speed (Potentiometer setting) is
decreased to back check speed. When the door stops at hold
open position the system sets the hold open speed and holds
the door open until activation and or timer is cleared. The
door will then close at close speed, (Potentiometer setting)
up to latch position (Potentiometer setting). Where the speed
is decreased by driving the motor in the open direction (fixed
setting), the power is set such that the spring will overcome
this power and continue to allow the door to close up to the
closed position. During the open cycle the safe opening (T1,
T1) is active and the Safety side Adj Pot sets the angle at
which the sensor is redundant, this can be set from Closed
up to back check position. During the closing cycle the safe
closing (T5, T6) is active and the Activate side Adj pot sets
the angle the sensor is redundant, this can be set from
Opened up to a few degrees of closed position.
