LED indicating status for the feed and travel drive system
1) Pentpak is powered, but the green start button on the Pentpak button has not yet been
pressed. A test is made for the can-bus to the HF-motor and the chassis.
Three blinks:
Short circuit in the digital communication system. The fault can be
in the saw head, 24V cable or inside the Pentpak.
a) Disconnect 24V cable from Pentpak. If the alarm disappears,
go on to b). If the alarm remains the same the Pentpak is faulty.
b) Connect 24V cable to Pentpak and disconnect saw head. If the
alarm disappears, go on to c).
If the alarm appears when connecting, the cable is faulty.
c) Connect 24V cable to Pentpak and saw head. If the alarm
appears when connecting, the connector on the saw head is
faulty.
2) Pentpak is powered, and the green start button on the Pentpak button has been pressed.
One blink:
Short circuit in the feed cable, saw head or any of the feed motors.
Two blinks:
24V under voltage alarm. The voltage has dropped below 18V.
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. Software update
needed in Pentpak.
Four blinks:
No digital servo found. Digital servo is defective.
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 saw head is connected or that the
power pack doesn’t find the saw head, e.g. damaged chassis-ID
chip or 24V cable.
To reset the alarm, press the emergency stop button and wait until
the alarm lamp goes out. Then press the green start button to start
the power pack again.
