Input out of range. The process input
is outside the range limits.
52. Make sure the range and actuation
are configured properly.
53. Check the input source.
54. Restore the factory calibration:
c) Disconnect the wiring from the
terminals on plug J2 on the input
board (see Figure 2-13). Place a
jumper across these terminals.
The controller should read room
temperature if it is configured for
a thermocouple input.
d) If it does not read room
temperature, see Section 3 -
Configuration and change the
IN1TYP prompt in the INPUT 1
group to another type of
thermocouple.
e) After the change, press FUNC
key, then the LOWR DISP key.
The controller should read the
correct room temperature. If it
does not, the unit has an input
failure.
f) Repeat step b. This time switch
the IN1TYP back to the originally
selected thermocouple.
g) Repeat step c. The controller is
restored with factory calibration.
h) Remove the jumper and
reconnect the thermocouple to
plug J2.
55. Field calibrate. See Section 7 – Input
Calibration.
56. Replace the input card.
