!
Note!
•
Danger of data loss.
If the controller is already
completely configured for output via relays and you
reduce the number of relays assigned to a controller,
then the
complete controller configuration (s.
page 50) is reset to the default values.
• If you change the relay assignment for the
controllers, you must use the controller menu
(s. page 50) to reassign a relay to all the functions
selected there.
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 NAMUR if the required relays 1
and 2 (compare page 19) are free.
E2
If the NAMUR function is enabled, the Alarm, Relay 1 and Relay 2 contacts are given the following functions:
"Failure" = Fault-signaling 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/calibration cycle.
