Adjusting of an AC Engine Regulation with 4 – 20 mA
Input/Output Signal AB076
The motor is pre-adjusted at works The following adjustment
instructions have observed ONLY when exchanging the print
board. The respective equipment of the drive is to be considered.:
1. Connect the board to mains, terminal 8 masse, terminal 9 phase and
terminal 10 protective conductor.
2. Apply to terminals 12 and 13 (control input) 4 mA
3. Move the motor to end position 0°, until the mechanic limit switch
is operated. ATTENTION: there is voltage!! At connection
terminals as well as on the reserve side of the board !
4. Turn the shaft of the potentiometer slowly until both signal lamps
are switched off.
5. Fit the gear of the potentiometer to gear of the motor shaft.
6. Apply 20 mA to control input = terminals 12 and 13.
7. Move the motor to end position 90° until the mechanic limit switch
is operated.
8. Turn potentiometer PT 2 (next to transformer) until no signal lamps
is on any more.
9. Then apply 4 mA control voltage and let the motor go to LOW end
position. In this position both signal lamps have to be off. Otherwise
balance adjustment by potentiometer PT 5.
10. Connect a measuring instrument to terminals 11 and 13 (output). In
end position LOW 0° the measure instrument has to show 4 mA.
Otherwise balance adjustment by potentiometer PT 11
11. Move motor to end position HIGH 90° the measuring instrument
has to show 20 mA. Otherwise balance adjustment by potentiometer
PT 9.
