1. INTRODUCTION
UI series of universal process indicator is a high performance indicator that can
be used to monitor wide range of input signal. The various input signals could easily
be selected from the front keypad without any change in Hardware. The Standard
model comes with 2-alarms, 24V auxiliary power supply for transmitter and analogue
retransmission 4 ~ 20 mA DC output. The unit features double display for indication of
process value and programming data. The large and bright PV display, robustness of
product makes the product suitable for industrial applications. The retransmission
output could be taken to PLC, recorder and other applications, for other functions. RS485 or RS-232 communication is also optionally available.
Applications
The instrument can measure and display any range of Current, Voltage and temperature
through RTD-Pt 100 signal input. The user can select data hold or high PV hold. The instrument can be
used with 2-wire Differential Pressure Transmitter, Pressure Transmitter, Temperature Transmitter,
Temperature Sensor or any other industrial process parameters (for non-linear input). RS485
communication is also optionally available. The input, output and the power supply are isolated.

1. Alarm setting: In the powered state press and hold SET key for more than 3 seconds, enter alarm
mode parameters setting menu. Press
2. <</RST Key, LEDflashes, press <</RST key to modify, and them press SET key to confirm. Press
SET key to read the following parameters one by one.
3. Rate setting: In powered state, press <</RST key and LED flashes, then you can modify the value
by Up and Down key. The factory setting is 1.00. Once the user want to set it to be other value.
then PV=Rate X (USP-LSP)+LSP. USP means Up limit, LSP means Down limits.
4. Zero point clear: In the displaying estate. without key operation, when the input zero point, press
and hold <</RST key for more than 2 seconds. It is for the sensor zero point clear.
5. The instrument will return to the measuring estate without any operation for 25 seconds.

ELIMINATE
Check all the connections and wiring to ensure them
being correct. Thoroughly check connections to power
supply terminals and signal input terminals.
Check if the PVF= 0.00 Check if the input signal is
conformity with the selected symbol.
In case instrument looses the control, check for the
output diagram connection is correct or check if the
components for output part are damaged.
When the instrument displays "UUUU", it means the
input signal exceeds the measured USP range. When
the instrument displays "LLLL, it means the input signal
exceeds the measured USP range. When the instrument
displays "LLLL", it means the input signal lower
measured LSP range, or input signal terminal
connection is contrary.
