Note!
•
The outside temperature of the motor is no indication of the inside temperature
of the motor. The temperature sensor is placed inside the motor windings and
does not monitor the outside temperature of the motor. The windings can be
working at a high temperature even if the motor is cold on the outside.
•
The warning light will be off when the temperature has gone down to a
temperature below 110°C. The motor cannot be restarted until the warning
light goes off.

LED indicating status for the feed and travel drive system
Pentpak is powered, but the green start button on the Pentpak button has not yet been
pressed. A test is made for the digital communication to the HF-motor and the machine.
Three blinks:
- - - - - - - - - - - - - - - - - - - - - - - -
Short circuit in the digital communication system. The fault can be in the machine, 24V
cable or inside the Pentpak.
Disconnect 24V cable from Pentpak. If the alarm disappears, go on to b). If the alarm
remains the same, the Pentpak is faulty.
Connect 24V cable to Pentpak and disconnect machine. If the alarm disappears, go on
to c).
If the alarm appears when connecting, the cable is faulty.
Connect 24V cable to Pentpak and machine. If the alarm appears when connecting,
the connector on the machine needs repair.
Pentpak is powered, and the green start button on the Pentpak button has been
pressed.
One blink:
- - - - - - - - - - - - - -
Short circuit in the 24V cable, machine or any of the feed motors in the machine.
Two blinks:
- - - - - - - - - - - - - - - - - -
24V under voltage alarm. The voltage has dropped below 18V (internally in the Pentpak).
Repair at an authorized Pentruder service workshop is required.
Three blinks:
- - - - - - - - - - - - - - - - - - - - - - - -
Automatic identification of machine type not working correctly.
The chassis-ID is wrong. Nothing is broken, but the HF-motor is incompatible with the
Pentpak or the machine. For example trying to use a 22 kW HF-motor with a Pentruder 6-
12HF saw head (invalid combination). Another example would be that a newer model
/type of machine is introduced that didn’t exist when the Pentpak was delivered. If this is
the case, a software update is required.
Four blinks:
- - - - - - - - - - - - - - - - - - - - - - - - - - - -
No digital servo found. Digital servo is defective. Repair at an authorized Pentruder service
workshop is required.
Continuously on:
The digital servo has shut off due to over temperature.
Push the emergency stop button to reset.
This can also indicate that no machine is connected or that the power pack doesn’t find a
machine on the digital bus, e.g. damaged chassis-ID chip or 24V cable.
