10.1 OPERATION
10.1.1 Sizing
From start up (size) the door will activate from morning entry (24Hrs,T9,
T10) regardless of key switch position, 1 Way input (T27,T28) with key
switch in one way. 2 Way input (22, T23) with key switch in two way, or
key switch Hold Open. The first movement will be in the open direction
- The speed of the sizing cycle is automatic and cannot be set from a
potentiometer the door drives opened to the full open position where the
system sets the counter to full open. The door closes at close speed then
latch up to closed position where the system sets the counter for closed
position. From these two parameters opened and closed position the
system calculates all the other parameters it requires for normal
operation i.e. latch position back check position etc.
• Notes
If the encoder is connected for opposite direction or faulty or
disconnected the door will operate erratically continuously opening ½
way closing latching and re-opening. This will continue to occur until
power is switched off
10.1.2 Auto Reverse on open
The auto reverse open is set from the backcheck position pot. This sets
the level of current required to trip the door as it is opening.
Normal operation
Key switch, activation, morning entry/fire alarm, locking, and safety.
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 backcheck
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, T2) 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.
