Selection of the input signal:


Selection S1 Input signals 4~20mA, 0~20mA, MANUAL
Selection S2 Input signals 1~5VDC, 0~5VDC
Selection S3 Input signals 2~10VDC, 0~10VDC

Functional adjustment:
VR1 BIAS: Standard output voltage adjustment. (Counter-clockwise adjust the
control signal, lower the input will produce the output.)
VR2 SFS: Standard output voltage adjustment. (Counter-clockwise adjust the
control signal, lower the input will produce the output.)
VR3 Max: Maximum output voltage adjustment. (Adjustment range 0~100%, counter-
clockwise adjustment will decrease the output. Set to zero will have no output.)


Descriptions for LED lights and trouble shooting:
L1 Power
Power light
On: Auxiliary power on.

Off: 1. Auxiliary power sources have no output-make sure AC1, AC2 auxiliary power
    sources have no output.
2. Control board malfunction
please replace the same spec. control board or send
    the power regulator for maintenances.
L2 Input
Input light
On: Control input signal is in.

Off: 1. Control input signal is not inplease check the temperature gauge to see if there
    is input, check the connection and the wiring.
2. Wrong connection on the electrodes of the control board
check the electrodes of
    the temperature gauge.
3. Set to zero on the Max VR of the control board or outside VR
check two VRs to
    see if any one of them is set to zero.
4. Control board malfunction
please replace the same-spec. control board or send
    the power regulator for Maintenances.
L3 Output
Output light
On: Power regulator is in output phase angle control. (light and dark based on the output.)
zero crossing control. (flash based on the output.)
Off: 1. If the abnormal light L5 is on. (fuse burn down or main power has no output.)please
    refer to ERR (L5).
2. If the temperature light L4 is on. (power regulator is overheating.)
please refer to TH (L4)
3. If the input light L2 is off. (No input signal.) please refer to IN (L2).
4. If the input light L2 is on. (control board malfunction.)
please replace the same spec. control board or send power regulator for maintenances.
L4 TH Err
On: 1. Power regulator is over heatingcooling fan is not operating, check the power, fan
    damage, or if the fan is stuck by any power object and get rid off it if necessary.
2. Bad ventilation or the ambient temperature is too high
please change the installation
    place or improve the ventilation.
Off: Normal, power regulator is not overheating.
    Source Err
Power source
abnormal light
On: 1. Main power source have no output or out-of-phasecheck the power output and all the
    abnormal conditions.
2. High-speed fuse burn down
please replace the same spec. fuse and check the
    shortage and the ground of the loading before restoring the power.
Off: Normal
