No supply voltage
Check the mains voltage. Make sure that the
control unit is connected to the mains (section 4
‘Electric module’). Make sure and replace, if
necessary, the fuses. Check that the jumper is
set at OUT + 24 V and IN + 24 V contacts of J5
connector. Check that

Incorrect mains
connection or low
supply voltage
Check the mains voltage. Check that all wires
of power cable are connected to the unit (no
broken wires). Switch wires for power cable
connection, for example, at L1 and L2 contacts
of
J1
connector (ensure the correct phase
sequence)
