Products - Thyristor Power Regulator W5 Series

Selection of the input signal

                    P1  
◎ 4~20mA、0~20mA、MANUAL Selection S1 (Input impedance : 249Ω)
◎ 1~5VDC、0~5VDC Selection S2 (Input impedance : 200KΩ)
◎ 2~10VDC、0~10VDC Selection S3 (Input impedance : 18KΩ)
       

Functional adjustment

VR1 BIAS Adjustment of standard output voltage.
(Counter-clockwise adjust the control signal, lower the input will produce the output.)
VR2 SFS Adjustment of buffer rising time.
(Adjusting range 1~22 seconds, clockwise adjustment will increase the time. No applicable for zero crossing type product.)
Constant current type : Adjusting range 2~16 seconds.
VR3 Max Adjustment of maximum output voltage.
(Adjusting range 0~100%, counter-clockwise adjustment will decrease the output. Set to zero will have no output.)
Constant current type :Current adjustment.(Adjusting range 50~100%, counter-clockwise adjustment will decrease the output.)
VR4 OLSET Adjustment of Over current.(Adjusting range 60~120%,counter-clockwise adjustment will decrease the output.)
PB1 RESET Over current RESET.

Descriptions for LED lights and trouble shooting

L1 Power
Power light
On: Auxiliary power on.
Off:
  1. Auxiliary power sources have no output → make sureAC1,AC2 auxiliary power sources have power 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 signal is not in → please check the temperature gauge to see if there is input, check the connection andthe wiring.
  2. Wrong connection on the electrodes of the control board → check the electrodes of the temperature gauge.
  3. Set to zero on the MaxVR of the control board or outsideVR → check twoVRs 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 the power regulator for maintenances.
L4 TH Err Over heating light On:
  1. Power regulator is over heating → cooling fan is not operating, check the power, fan damage, or if the fan is stuck by any 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.
L5 FUSE/ Source Err Power source abnormal light On:
  1. Main power source have no output or out-of-phase → check 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
L4&L5 O.L Over current light L4 and L5 On: Power regulator is over current please check the shortage and the ground of the loading before press
                           PB1 to reset.
Off: Normal
