Verify that sensor is wired to proper
terminals. Next, check that the controller
is programmed for the correct input type.
Most commonly seen when controller is
programmed for a RTD, while a
thermocouple is connected.
Verify that the input is wired to the
proper terminals. Next check to see if
the input type is set to the proper value.
Most commonly seen when controller is
programmed for a 4 to 20 mA input and
0 to 20 mA signal is wired to the
controller.
Input signals may normally go above or
below range limits. If not check input
and correct the process temperature or
increase temperature range limits using
tP-H and tP-L.
Attempt to reset the factory default
settings using the instructions in the next
section. If still has error, call customer
service for a return goods authorization
number to have the controller evaluated
at the factory.
