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
in→please 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
Temperature
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 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.
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
