ELECTRICAL TROUBLESHOOTING GUIDE
This document contains the troubleshooting guide for the
electrical system.
General
All motors coming from Sweden are tested to run with the right
Phase-sequence on incoming Power Supply. Wrong Phase-
sequence means that all motors are rotating the wrong way.
Troubleshooting guide
1. Control panel
Follow the Electrical Drawings on the frontpage (Voltage and frequency).
Check the voltage to the control panel with the help of a Volt-meter.
OK?
Main switch may be broken or fuses for the power supply
may need to be changed.
If none of the above examples solved the problem:
Contact El-design support
No

Find out which door-switch that fails by checking the diode on
the door switches. Green light = OK. Check the CableNo on
the El-drawings.
Check all connections in the junction boxes and in the
control panel.
Look for loose wires on the relays and on the terminal blocks.
OK?
No
Yes
Check the digital input on the PLC.
(The light is on if it is functioning.)
Check if the relay has power.
If none of the above examples solved the problem:
