Setting sequence
1. Go to lamp fault setting by selecting Set/Set/LF.
1. If necessary adjust level A and B with + / - , select Set and then select Next.
1. If the CCR is with direction changer, choose the other direction and adjust levels A and B as in step 2. The levels for both directions are
updated whenever direction is changed.
1. If necessary adjust delay time as in step 2.
Operational test
Adjust the alarm level below actual lamp fault level of the circuit or make more lamps faults than the alarm levels into the circuit and make
sure that alarms are generated in due time.
4.6.3 Earth Fault Setting
When the isolation resistance of the AFL-circuit decreases below the earth fault levels (A and B) corresponding fault indication
is generated. In case the earth fault maintenance switch function is enabled (i.e. selected on from the system settings) and the
maintenance switch is on level B causes tripping of the CCR and is therefore a protective function.

Setting sequence
1. Go to Earth fault setting by selecting Set / Set / EF.
1. If necessary adjust levels A and B with + / - , select Set and then select Next.
1. If necessary adjust delay time as in step 2.
Operational test
Adjust the alarm level higher than actual isolation level of the circuit or make an artificial earth fault in the circuit and make sure that alarms
are generated in due time.
Warning!
De-energize the CCR before making the earth fault.
