8.4 Checklist
• LED ON green does not light up
- Check fuse control 500V 1.6 A, if defective check external wiring, also applies
to faults of external fusing.
- Check Power Controller fusing. If fuse is defect then check load and wiring to
load. Synchronization voltage is supplied to X1.1.
- With transformer load, check phase angle 1 (TRAFO ADAPTION) - fuse release
caused by rush current is possible if setting is incorrect.
- Check 5 Volt to X2.8. If this voltage is absent or too low, there is a defective
component.
• Supply available but no load current
- Check that pulse lock is cleared (jumpered) terminal X2.1,2
- Check set point
- Check for load interruption
- Check blinking LED indications (chapt. 3.3)
• Load current does not have expected value
- Check set point Terminal X2.4 against X2.3 ground or
Bus set point (with optional bus module)
- Set point/controller value, max. value correctly parameterized
- Check all parallel load resistances for current conduction
- Check control end for correct setting
- Check control characteristic adjustment (U, live zero)
• Load current flows uncontrolled
- In rare cases a Thyristor short-circuit can occur.
