Set up 1 – Temperature
Temperature compensation must only be carried out in the Conductivity operating mode
(operating mode selection, Field A1, p. 31).
The
temperature coefficient
α
indicates the relative change in conductivity per degree
of temperature change. It depends on both the chemical composition of the solution as
well as on the temperature itself.
To include the dependency, three different types of compensation can be selected in
the Mycom S CLM 153 :
•
Linear compensation
•
NaCl compensation
•
Compensation via table (four different tables are available).
F2
NC contact
NO contact
Selection acc. to NAMUR:
(only, if NAMUR is activated)
Assignment of NAMUR contacts as NC contact (= nor-
mally closed contact, opens when relay active) or NO
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:
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/
calibration cycle.
F3
NC contact
NO contact
Select controller contacts as NC contact or NO
contact.
F4
NC contact
NO contact
Select limit values as NC contact or NO contact.
F5
Steady contact
Wiping contact
Contact type: Fault-signalling contact
(only, when NAMUR function = off)
Steady contact
= Active for as long as an error is
present.
Wiping contact
= Active for 1 second when an alarm
signal occurs
F6
Chemoclean is always a NO
contact.
Note in display
(only, when the full ChemoClean function is selected
in field F1, which means CCC and CCW)
With the ChemoClean function, the valves of injector CYR
10 are effected with a NO contact.
