DIP 4
expired.

POTENTIOMETER
PT1 (TRIMMING POTENTIOMETER 1): BRAKE
When the gate reaches its limit switch, the drive shuts down.
Depending on weight and function of the gate, it may continue to
move on a bit further before stopping. The brake function is for the
active braking of the gate in order to minimise this additional
movement. Left stop = brake OFF.
PT2 (TRIMMING POTENTIOMETER 2): AUTOMATIC CLOSING
(TIMER TO CLOSE)
The waiting time for the gate for GATE OPEN can be defined.
The gate is closed 0-150 sec. after the set time expires.
Only possible if a photocell is connected (771E/770E).
(Not possible for self-hold and channel separation)
PT3 (TRIMMING POTENTIOMETER 3): FORCE SETTING
Definition of the force with which motor is to operate. The required
force depends on weight and function of the gate.
PT4 (TRIMMING POTENTIOMETER 4): RPM SENSOR
See RPM sensor description
Not active for "Slow run"
