9. Trouble shooting
Only skilled and trained technical personnel should carry out the necessary trouble shooting operations
at the unit.
9.1. No output voltage
- Is the mains voltage present?
- Is the mains switch in on-position?
- Is the input plug correctly connected?
- Is the polarity correct or short circuit at the output?
- Paralleled units: incorrect polarity at external decoupling diodes?
- Monitoring of output voltage high V> signalize an error (lights LED V>?); switch the unit off and on
again and check the adjusted value of V> (see section 5.4)!
If the module still does not work even though all checks have been done, contact your sales agent or
the ELTEK VALERE INDUSTRIAL service department.
9.2. Deviation of the output voltage
- Operates the module in constant current mode (overload)? >Reduce the load!
- Adjustment of output voltage value V
O wrong? >Adjust the output voltage to nominal values (see
section 5.4)!
- Cable break at external sense links?
- Voltage losses at decoupling diodes on output side? >adjust the output voltage to higher level or use
sense links!
If the module still does not work even though all checks have been done, contact your sales agent or
the ELTEK VALERE INDUSTRIAL service department.
