Operation – continued –

MAX limit / MIN limit

Only applicable if:

■ Relay contact 1 (feedback LED 1) works as switching output for MAX limit

■ Relay contact 4 (feedback LED 4) works as switching output for MIN limit

LED 1 lights up once the set MAX limit is reached.

Relay contact 1 opens (safety circuit).

LED 1 goes out once the value falls below its limit.

Relay contact 1 closed.

LED 4 lights up once the set MIN limit is reached.

Relay contact 4 opens.

LED 4 goes out once the value exceeds its limit.

Relay contact 4 closed.

MAX limit / MIN limit=Automatic intermittent boiler blowdown

Only applicable if:

■ Relay contact 1 (feedback LED 1) works as switching output for MAX limit and MIN limit

■ Relay contact 4 (feedback LED 4) works as switching output for automatic intermittent

boiler blowdown

LED 1 lights up once the set MAX or MIN limit is

reached. Relay contact 1 opens (safety circuit).

LED 1 is not lit if the actual value is between the MIN

and MAX limit. Relay contact 1 closed.

LED 4 is lit during intermittent blowdown and relay

contact 4 is closed. The intermittent blowdown valve

opens.

LED 4 is not illuminated during the time between

intermittent blowdown. Relay contact 4 is open, the intermittent blowdown valve is closed.

Test

Note

The MIN limit is activated approx. 60 seconds after the mains voltage has

been applied. During this time LED 1 or - depending on the setting - LED 4

is flashing rapidly.
