5.10.1.2 Configuration: Inputs/Outputs/Pump: Assign Relays
You can use this menu to assign different functions to up to eight
relays which are installed in the analyzer. These functions can be
signals for limits or ranges, status signals, and the functions of the
external solenoid valves. If an option module is present, eight additional
relays, i. e. a total of 16 relays, can be assigned to the corresponding
functions.
Each function may only be assigned to one single relay. The analyzer
outputs an error message if you attempt a double assignment for a
relay which has already been assigned. A relay to which a function has
not been assigned is shown on the display by a dash.

The pin assignments of the relays in the de-energized state are described in Chapter 3.
S Relays for limits
The upper and lower limits can be defined as events for triggering
relays. Select the desired relay number in the second and third
lines.
This function is specific to the component.
