1) Check the input signal source and the
connecting line.
2) Make sure that the input signal is in
accordance with instrument configuration.
Otherwise, modify the input configuration P1
(see chapter 3.2).
3) If no error is detected, send back the
instrument to your supplier for a check.
ERRORS
Diagnostics are run at instrument power up and
during normal mode of operation.
If a fault condition (error) is detected the display
will alternately show "Er" and the error number.
The following is a list of possible errors in
numerical order.
Also causes, instrument output conditions and
possible remedies are briefly described.
Some errors reset the instrument; if the error
persist, send back the instrument to your supplier.
ERROR LIST
100
Write EEPROM error.
150
General hardware error on the CPU
card.
200
Protect register memory error.
The controller performs this check
every 2 seconds.
Set the switch V2 in open condition.
Switch on the controller. Set the

power the controller.
201 - 219
Configuration parameter error (2xx.
where xx is the Configuration code).
The two less significant digit’s show
the number of the wrong configura-
tion parameter.Return to the
configuration procedure and check
the values.
301
RTD calibration error.
305
Thermocouple input calibration error.
307
RJ input calibration error
400
One or more control parameters are
out of range with respect to the
allowed values.
It may appear at controller power up
after configuration changes.
Push and hold
t
and
s
pushbuttons simultaneously and
