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 Back check
position pot. This sets the level of current required to trip the
door as it is opening.
