Spare Part
• Ballast circuit LZS200/1000 [00344207-xx]
Removal / Installation
➢ Wear the ESD wristband.
➢ Loosen the 4 screws fastening the plexiglass cover and remove this.
➢ Press down the lock on the ballast circuit (see "3.6.3 Control Unit" [➙ 3-48]).
➢ Carefully pull the ballast circuit out of the control unit.
➢ Carefully insert the new ballast circuit.
➢ Make sure that the ballast circuit engages properly.
➢ Refit the plexiglass cover and screw into place.
Settings
• No settings are required.
NOTICE
Ballast circuit with integrated micro fuse
There is a micro fuse T 10A/440V on the ballast circuit.
Check this fuse for continuity with the help of a digital multimeter and replace if
necessary.
NOTICE
Braking resistor for lifting axis
The braking resistor for the lifting axis is 12 Ohm +- 10%
This can be measured on the back plane. To do this, first make sure that the WPC is
switched off and then remove the ballast card and the servo card for the feed axis.
