7.2  Supply voltage

 

Connect the supply voltage of the device to terminals L+ and L-.

For safety reasons the unit can only be restarted by separation from the voltage 

supply in case of a fault. 

It is thus recommended to install a RESET button in series with the L+ circuit.

The external supply unit must have a safe separation. In case of a fault the 

supply voltage can exceed the value of 60 V DC for a maximum of 200 ms, 

but must not exceed the value of 120 V DC.
After power on or a RESET the device carries out self diagnostic functions. 

This self diagnosis lasts approx. 6 seconds. The unit is then ready for 

operation.

7.3  Switch point setting

 

Set the requested switch point via a hard-wired bridge on the terminals S33, 

S44, Y2 or Y6.

Only change the switch point when disconnected from power. 

When switched on, a change of the circuitry will produce an error message 

of the device.
