Chapter 3 Controller Descriptions and Operation
3
Warning: No modification of parameters or settings without professional training
and qualification by the manufacturer or authorized distributor.
USER screen is subject to change with the version of software update and without notice. The
majority of the message and function are as follows:
[Version]: Software versions for PLC, HMI, modules of A/D and others. They are extremely important
for technical support, maintenance and service.
[Accumulator]: Hour accumulator for equipment operation since commissioned.
[Input Status]: At situation of warning or abnormal, it is necessary to view if all the inputs are
available to the controller, for example over-temperature switch, pressure switch, low-level
cutout, door switch etc. Input Status may help service engineer to analysis cause of the fault
and provide troubleshooting and solution.
[Deviation Adj]: Intended for deviation adjustment for display of temperature and humidity at
screen of HOME as compared to certificate data from third party body. Standard procedures
shall be followed for calibration, otherwise new errors may be introduced.
[View PID]: PID parameters affect the control of temperature and humidity significantly, whether
overshooting during ramping and pulling down, or stability once stabilized. View the PID
parameters for proper settings if overshooting or stability is beyond expectation. For PID
adjustment, consult Xtemp or your local authorized distributor.
[Watchdog DA]: Once software locked against normal operation as a result of un-authorized use
of the equipment, consult Xtemp for deactivation of the Watchdog. Under normal use
condition, no activation of the Watchdog, so no necessary for deactivation of the Watchdog.
[Output Status]: At situation of warning or abnormal, it is necessary to view if all the outputs are
available to the external devices, for example circulating fan, compressor, lamps etc. Output
Status may help service engineer to analysis cause of the fault and provide troubleshooting
and solution.
[Time CE]: To adjust the time error of the controller system, or to input a correct time once
repaired.
[Sensors Scan]: At situation of temperature and humidity abnormal, it is expected to view if any of
the sensor is in normal condition. Sensors Scan may help service engineer to analysis cause of
the fault and provide troubleshooting and solution.
[Warning MSG]: For view of warning history, including warning message and time of its occurrence.
Warning MSG may help service engineer to analysis cause of the fault and provide
troubleshooting and solution.
