LED type warning lights on the power pack
There are four red warning LED:s on the Pentpak. Below is an explanation of the respective
functions.
LED for indication of loss of one or more phases
One blink:
Loss of phase on mains. Loss of one power supply phase line can
be caused by a blown fuse, faulty cords, faulty plugs or receptacles,
or other problems. If the light is on, check fuses, input voltage,
cords etc.
Two blinks:
Too low incoming voltage. Can be caused by too long and/or small
extension cables. Check voltage, connectors, cords and generator if
applicable.
Three blinks:
Too high incoming voltage. Connect only to 3-phase 380 – 480V.
Check voltage, connectors, cords and generator if applicable.
With one phase missing from the power supply, feeding may work, but the blade will not rotate.
General advice to eliminate any of the above fault conditions: Eliminate the cause of the problem,
i.e. replace blown fuses, repair cords, repair or replace plugs and receptacles.
Note: To allow capacitors in the inverter to discharge, at least one minute must elapse after the
emergency stop button is pressed and the green start button is pressed.
LED indicating status for the power pack
One blink:
Overcurrent alarm. May occur if the blade is jammed in the cut,
Press start blade switch to reset or unplug the unit for 60 seconds.
Two blinks:

If the alarm doesn’t go away, the unit must be checked by a
technician trained on this equipment.
Four blinks:
Frequency inverter alarm. Must be checked by a technician trained
on this equipment.
Quick blinks:
Temperature in the frequency inverter has risen to a too high level.
Protect from direct sunlight, increase water flow.
