5.12 – Check filter board
Tools needed :
• Multi meter
Verify that in the terminals "IN1" and "IN2" must be voltage (230 VAC).
Verify that there is the same voltage in the terminals "OUT1" and "OUT2".
Check also the voltage between junctions under fuse "S1/S2" and "S3/S4". If there is not tension
between these points, you should replace the fuse "F1" (1A). If there is input voltage(IN1 e IN2),
but no output voltage (OUT1 and OUT2), you should replace the filter (Fig. 31).

5.13 - Contactor test
Tools needed :
• Multi meter
Using the multi meter check for voltage (230 V AC) between terminals 2 and 4(Fig. 32).
If there isn't this voltage, check the cables.
Measure the voltage between terminals 1 and 3(Fig. 33) must be 230VAC.
If there is tension between the terminals 1 and 3 the test is OK, otherwise is NOT OK.
