1. INTRODUCTION
UC508 economy is a Microprocessor based Digital Process Controller, which
can be applied in high-precision measurement and control of temperature, pressure,
discharge, liquid level and humidity etc... A four-digit LCD dual display shows
measured value and set-value for all programming parameters. Instrument
configuration is achieved from the front panel keyboard, without any hardware change.
The user should read this manual thoroughly before using the instrument. It must be
handled with care and should be used accordingly for best results.
2. PRESENTATION
2.1 Features
1. Input signal: Thermocouple, RTD, direct voltage, current programmed from the front panel.
2. Outputs can be set on-off control or PID control with configurable direct/reverse action modes.
3. The input uses digital correction system; there is nonlinear correction form of communal used
thermocouple and resistance thermometer detector.
4. Control output modes hold out relay contact switch, solid-state relay driving voltage, and singlephase thyristor zero-crossing trigger signal etc.
5. Comprehensive self-detection and protection. In case of error, it provides automatic repair or
prompt message and closes the output.

respectively.
Parameter setting block: Under PV/SV display block, the instrument will enter
parameter setting block by pressing down SET key for 2s. The PV screen displays
parameter name and the SV screen displays parameter value, the last figure of which
will flash. Edit parameter value with ◄, ▼, ▲ keys. Then press SET key to confirm the
change and switch to the next parameter name, or press down SET key for 2s to
confirm the change and return to PV/SV display block. The instrument will return to

PV/SV display block if there is no key action for 60s, in this case, the last change to
the parameter will be cancelled.
Self-tuning block (only available when LOC=0 and the instrument are under PID
control mode): Under PV/SV display block, the instrument will enter self-tuning block
by pressing down key for 2s. The PV screen displays the process value, and the SV
screen displays a flashing -At- at interval of 0.5s (during the process, the instrument
can enter and exit parameter setting block and output display block with no effect on
self-tuning. But the self-tuning prompt will disappear). On completion of self-tuning, the
PID parameters of the instrument will be automatically changed and saved and the
instrument will return to PV/SV display block automatically. Press down ▼ key for 2s
when -At- on the SV screen stops flashing to exit the self-tuning block during self-
tuning process.
8. MAINTENANCE
Metrological verification should be conducted annually for the instrument. If the
instrument goes beyond error limit, which often results from a damper environment,
dust or corrosive gas, the inner part of the instrument should be cleaned and dried. In
case the accuracy can not be restored by cleaning and drying, the instrument should
be sent back as default product to the factory for troubleshooting.
