Low current
on CS1
A Current < 10 Amps has
been detected on chopper
channel 1 by
current sensor 1 during
the chopper test at
power-up.
1. Measure voltage across the current sensor (CS1).
a) Red to black = +15 VDC, green to black = -15 VDC,
white to black = 0 VDC at idle and varies with current
output (4 VDC = 100 amps).
b) If possible, take a voltage reading on current sensor
while trying to cut. Ratio is 4 VDC = 100 amps.
c) If the current sensor voltage is approximately 6.4 VDC
or greater at idle, replace the current sensor.
107
High current
on CS2
A Current > 35 Amps has
been detected on channel
2 by current sensor 2
during the chopper test at
power-up.
1. Verify that there is not a short circuit between the negative
lead and the work lead.
2. Measure voltage across the current sensor (CS2).
a) Red to black = +15 VDC, green to black = -15 VDC,
white to black = 0 VDC at idle and varies with current
output (4 VDC = 100 amps).
b) If possible, take a voltage reading on current sensor
while trying to cut. Ratio is 4 VDC = 100 amps.
c) If the current sensor voltage is approximately 6.4 VDC
or greater at idle, replace the current sensor.
108
Transfer at
power-up
The system has detected
current on the work lead >
3.5 amps during power-up.
1. Disconnect J6.6 on the I/O PCB (PCB6). If the problem is
resolved, replace PCB6.
109
Coolant flow
at power-up
Coolant flow is > 2 lpm
(0.6 gpm) when the pump
is off.
1. The coolant flow sensor was bypassed or the flow switch
is faulty. Replace the flow switch.
111
Coolant over
temp at
power-up
Coolant is indicating an
over temp at power-up.
1. Verify that the coolant temperature sensor has not been
jumped out or the wires to the sensor are not shorted out
in the harness.
2. If not, the coolant temperature is over the set point and
needs time to cool to 70° C (158° F).
116
Watchdog
interlock
An error occurred with the
CAN communication
system.
1. Verify that the power supply to gas console control cable is
not damaged and is properly connected to PCB4 and to
the back of the gas console.
2. Verify that the power supply to gas console power cable is
not damaged and is properly connected inside the power
supply and to the back of the gas console.
3. Use the CAN bus tester to verify CAN bus
communications.
