ARNING
Potentiometer is suitable for board balancing
exclusively
and has not to be used for any
different need.

9.2.4
Calibrate the S1 cam [closing] nearly for starting point of microswitch.
9.2.5
Turn the shaft of potentiometer clockwise
3
till its mechanical stop.
9.2.6
Adjust the control device on 6 mA [or 3 Vdc], wait for motor operation and reset it
on 4 mA [or 0 Vdc] and check 0° achievement.
9.2.7
Whenever 0° set would not be reached, spin the shaft of potentiometer counter
clockwise
4
till 0° exactly.
9.2.8
Adjust the control device on 20 mA [or 10 Vdc] and check the max. opening time.
9.2.9
Calibrate the S2 cam nearly for starting point of microswitch.
9.2.10
Adjust the control device on 4 mA [or 0 Vdc], setting the motor at 0° on return.
10 OPERATING
After installation and adjustment of the control lever system check that switch and wiring of
the circuit are correct.
Check that the AB1...SE rotary gear motor duly controls the device it is meant for.
Check that the AB1...SE rotary gear motor runs in accordance with the given manual input.
Check that the AB1...SE gear motor, the lever system and the controlled device are
mechanically connected in a correct and safe way.
Check that the levers' movements occur smoothly without jamming or blocking due to
other objects.
11 MAINTENANCE
The AB1...SE rotary gear motor does not require any particular current maintenance.
The AB1...SE gear motor does not require any lubrication because the gear mechanism is
immersed in a grease bath.
Do not disassemble any internal part of the AB1...SE gear motor. In case of non-
