9. Troulbe shooting
• Check if there is power to the unit according to specifica-
tion. If the power is ok,
• Turn off the power for 5 seconds and see if the relay is
energized after power on again.
If not, turn off all the power to avoid risk of injury!
9.1. Check the LED on the OLC
• ED Off: Oil level good, no failures
• LED On: Oil level low – there could be a leak or the oil is
somewhere else in the cooling system and unavailable
for the compressor
• LED is flashing:
1) OLC is not correctly mounted – check that the device
is mounted correctly in the prism and the turn-ring is
tightened properly. If the LED flashes during start-up
there may be foreign light entering the prism from
outside
2) The supply voltage might be too low. Check voltage
levels
3) The device has an internal fault and needs replace-
ment
