NOTHING SEEMS TO BE WORKING (CE/AS/NZS OR EURO MODELS)
Turn the system off and verify that all screws on the terminal block are tight.
Pull on the cables to ensure that they are solidly fixed. Turn the device back on.
For dual phase system
∙ Measure the tension between line 1 (L1) and neutral (N)
and between line 2 (L2) and neutral (N).
You should measure 230V in both cases.
For triple phase system
∙ Measure the tension between line 1 (L1) and neutral (N) and between line 2 (L2) and neutral (N) and between line 3
(L3) and neutral (N).
∙ You should measure 230V in all cases.
For delta triple phase system
∙ Measure the tension between line 1 (L1) and line 2 (L2), between line (L1) and line 3 (L3)
and between line 2 (L2) and line 3 (L3).
∙ You should measure 230V in all cases.
For single phase system
∙ Measure the tension between line 1 (L1) and neutral (N). You should measure 230 V.

If tension readings are correct:
∙ Verify that the keypad is linked correctly to the control system.

If readings are correct and keypad is linked correctly:
∙ For in.yj systems, replace fuse (F2).
∙ For in.ye, in.yt and in.xe control systems,
verify the transformer fuse.
∙ Replace the transformer fuse, if necessary.
∙ If the problem persists, replace the control system.
