Problem:

Homing for the drawer pull-out system is not executed or stops and error message “Automatic Homing Failed” appears.

Possible Causes & Resolutions:

• Check the light barrier in front of the drawers. It must be ensured that the sensor above has a direct line of sight to the reflector below. If necessary, realign and check that all screws of the holder are tightened.

Problem:

Some Beckhoff i/o terminals are not active and status LEDs are off, control does not respond to commands.

Possible Causes & Resolutions:

• The 24Vdc supply of the EK1100 coupler or the EL9410 intermediate supply terminal is missing or the voltage is too low > Check all connections, measure voltage, check fuses.
• Bad contact between the terminals > Switch off the main power and remove the terminals. Clean the contact between the terminals.
• Defective EL9410 intermediate supply terminal > Exchange terminal.
• Defective EK1100 coupler > Exchange coupler.

Problem:

After main switch off and on again, HMI piece counter values and settings are lost or old recipes are loaded.

Possible Causes & Resolutions:

• IPC has not shut down correctly.Check the IPC after you switched off the main switch: Normally it will continue to run for at least 30 seconds to shut down correctly. If LED’s of IPC goes off within a few second, the battery of the UPS – unit is dead and needs to be replaced.

Excel Spreadsheet – CM Electrical Components List

An overvoltage suppressor (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge suppressor attempts to regulate the voltage supplied to an electric device by either blocking or by shorting to ground voltages above a safe threshold.

These surge suppressors are built in to the latest Pacemaker models and machine controls (from 2009).

Check, if one or more modules of the surge suppressors are red/defect. Replace the red modules.

Attention!!!

Do not bridge the signalling contacts and run the machine with defective red modules because they no longer protect the system from voltage peaks!!!
If the modules are defective, check the main supply. Measure and check all voltages between the phases and all phases to earth before exchange the modules and restart the machine.

1. Exchange the defective servo drive with the new one:
   The safety card is inserted, from above, in the card slot marked “safety” in the servo drive. Loosen the screw carefully.
2. Transfer the safety card from the original to the new one:
   Carefully pull on the screw.
3. The servo drive will be controlled by the IPC and needs no programming.

Attention: Install the safety card without using force!
