5. Indicators
The following functions are indicated with LED´s:
LED 1 green Line Supply
LED 2 clear Thyristor triggering
LED 3 yellow Drive release
LED 4 red Current limit, Over-speed
Caution !
Do not use any megohmmeter, buzzer or similar test instrument !
Measuring instruments must be galvanically seperated from line
voltage.
6. Functional tests and adjustments before operation
6.1 Armature-voltage control (UA-control)
1) Check all connections with an ohmmeter for short circuits to ground.
2) Check line supply voltage with reference to the Type Marking.
3) Set jumpers I, II, III (refer to layout chapter 9).
4) Measure the resistance between terminal 18dz and 16dz with an ohmmeter. The
resistance has to be least 400 ohms (220 V connection). If necessary change the
polarity of the ohmmeter.
5) Potentiometer P2 Deceleration-time, set in centre position.
Potentiometer P3 Acceleration-time, set in centre position.
Potentiometer P5 IxR compensation, set fully counter clockwise.
Potentiometer P6 Stability, set fully clockwise and turn back 30%.
Potentiometer P1 Minimum speed, set fully counter clockwise.
6) Switch on line voltage. The green LED 1 must now light up.
7) Measure field voltage between terminals 18dz (F+) and 16dz (F-) with a multime-
ter (moving coil instrument, min 333 Ohm/V). The field voltage must read 200 V at
230 V line voltage. Measure potentiometer voltage between terminals 30z - 26z.
If the potentiometer is turned clockwise the armature voltage (motor speed) will
increase. Set speed potentiometer P4 (max. speed) fully clockwise and adjust the
armature voltage (motor speed) for the requested maximum speed. Set speed
potentiometer fully counter clockwise (output voltage must now return to 0 V) and
adjust with P1 (min. speed) the requested minimum speed.
