Relay settings

Relay assignment

In V1H4 and V1H9, relays 1 or 2 can be assigned to the corresponding measuring
channel by entering the channel number »1« or »2«.

Step

Matrix Entry Significance

1 

V1H9 

e.g. 1

Relay 2 is assigned to channel 1

Register entry

Switch point

The switch point is set at V1H0 for relay 1 and V1H5 for relay 2 in the units used for
calibration or linearization.

Step

Matrix Entry Significance

Note!

•

If the relays are assigned to channel 2, the switch point is set at V8H6 as described
in Chapter 8, Section 8.2 and 8.3.

Fail-safe mode

This function determines whether the relay is to act as a minimum or maximum limit
switch, entries are made at V1H1 for relay 1 and V1H6 for relay 2:

•

0  =  minimum fail-safe: the relay de-energises if the level or volume drops 

    below the value

•

1  =  maximum fail-safe: the relay de-energises if the level or volume rises 

    above the value
