1. From the PathPilot interface, toggle the Coolant button to On.
2. Examine the coolant receptacle for power. If there's no power, and fuse F1
has continuity, it's likely that the K3 relay failed.
3. Power off the machine (see "Power Off the Machine" (page54)). Then,
install a short jumper between wires J5-1 and J5-2.
4. Power on the machine (see "Power On the Machine" (page52)). If the
pump runs when the machine is powered on, replace the machine control
board.
1. Power off the machine (see
"Power Off the Machine"
(page54)). Then, install a short
jumper between wires 109 and
125 on the machine control
board.
2. Power on the machine (see
"Power On the Machine"
(page52)). If the pump runs
when machine is powered on,
it's likely that the problem is the
K3 relay.
Note: This relay will fail if too
high of a current draw passes
through it. This is common
when electrical loads much
larger than the coolant pump
are plugged into the coolant
outlet.
