MAINTENANCE
PROBLEMS WITH THE INDICATOR
Connection errors and inadequate programming are the most
common problems encountered during the indicator operation. A final
revision can avoid loss of time and damages.
The indicator displays some messages to help the user identify the
problems.
MESSAGE
DESCRIPTION OF THE PROBLEM
----
Open input. Without sensor or signal.
Err1
Err6
Connection and/ or configuration problems. Check
the wiring and the configuration.
Other error messages may indicate hardware problems requiring
maintenance service.
CALIBRATION OF THE INPUT
All inputs are factory calibrated and recalibration should only be done
by qualified personnel. If you are not familiar with these procedures
do not attempt to calibrate this instrument.
The calibration steps are:
a) Configure the input type to be calibrated.
b) Configure the lower and upper indication limits for the maximum
span of the selected input type.
c) Connect to the input terminals a signal corresponding to a known
indication value a little above the lower display limit.
d) Access the parameter
inLC
. With the keys and adjust the
display reading to match the applied signal. Then press the key
to store.
e) Inject a signal that corresponds to a value a little lower than the
upper limit of indication.
f) Access the parameter
inHC
. With the keys and adjust the
display reading to match the applied signal. Then press the key
to store.
Note: When checking the indicator calibration with a Pt100 simulator,
pay attention to the simulator minimum excitation current
requirement, which may not be compatible with the 0.170 mA
excitation current provided by the indicator.
