RAYCHEM 910 Monitoring and Maintenance Parameters
Monitored variables
Description
CTL temp
Control Temp
TS1 temp
This temperature is the value that the controller is
reading from the RTD connected to its TS 1 input.
TS2 temp
This temperature is the value that the controller is
reading from the RTD connected to its TS 2 input, if the
sensor is being used.
Load current
Displays the current being drawn by the heating cable.
(A)
GFI current
Displays the ground-fault current being drawn by the
heating cable.
(mA)
Maintenance Tests
Trace testing
The TEST TRACING feature temporarily overrides the
temperature control, and power
s the heating cable
circuit for 30 seconds without having to modify the
CONTROL SETPOINT temperature or any other
configuration parameter.
Display test
The DISPLAY TEST feature provides an easy method of
illuminating eac
h display segment and all the LEDs of
the Operator Console to ensure that they are
functioning properly.
Recorded Values
Temperature values
This feature indicates the maximum and minimum
temperatures recorded by the
C910-485 since the last
time the values were reset
:
Max Control temp
Min Control temp
TS 1 Max Temp
TS 1 Min Temp
TS 2 Max Temp
TS 2 Min Temp
Contactor cycle count
This feature indicates the total number of off-to-on
transitions a contactor
has made since the last time the
CONTACTOR CYCLE COUNTER was reset.
(See
keystroke procedure for
resetting)
Time in use
Indicates the total hours in use of the controller since
its initial operation or since it was last reset.
Time since last reset
This feature indicates the total hours in use of the
controller since the last reset.
Peak ground-fault current
This feature indicates the highest instantaneous
gr
ound-fault current measured since the last time the
PEAK GROUND
-FAULT CURRENT was reset. This
current value is written to the controller’s non
-volatile
memory once every 24 hours or whenever any
maintenance data is reset by the user.
