You can assign the function of up to 5 relays here. The relays 1 and 2 will be assig-
ned to an activated NAMUR function and will not be available for other functions
(compare with page 27).
Selection:
N/C / Controller / Limit / CCW / CCC
N/C : no function
Controller : Controller control using relay
Limit : Limit contactor function
CCW : Chemoclean water. Water supply for the Chemoclean function.
CCC : Chemoclean cleaner. Cleaner supply for the Chemoclean function.
(Together, CCC and CCW form the "Chemoclean" function. You can find
information on Chemoclean on page 98 ).
The limit value/controller contacts are configured in the menu "PARAM"

!
Note!
• Danger of data loss. If you change the relay allocation after configuring the
controller and the number of relays available to the controller is reduced , the
complete controller settings (see page 74) are reset to the default values.
• If you change the relay assignment for the controller, you must use the controller
menu (see page 74) to reassign all the functions selected there to a relay.
Example : Relays 4 and 5 are assigned to the controller and you change the
controller assignment to relays 5 and 6 (number of relays remains 2)
(no data loss, providing the number of assigned relays is not reduced!).
• You can only activate the NAMUR, when the required relays 1 and 2 are free
(see page 27).

Selection acc. to NAMUR:
(only, if NAMUR is activated)
Assignment of NAMUR contacts as "Active open" contact (= normally closed
contact, opens when relay active) or "Active closed" contact (= normally open
contact, closes when relay active).
If the NAMUR function is enabled, the alarm, relay 1 and relay 2 contacts are given
the following functions:
• "Failure" = Fault signalling contact (terminals 41/42): Failure alarms are active if
the measuring system is not working correctly or if process parameters have
reached a critical value.
• "Maintenance required " = Relay 1 (terminals 47/48): Warning messages
become active when the measuring system is working correctly but requires
maintenance or a process parameter has reached a value which requires
intervention.
• "Function check" = Relay 2 (terminals 57/58): This contact is active during
calibration, maintenance, configuration and during the automatic cleaning cycle.
