ERROR CODES

WARNING!

Bus voltage of 400 V DC will be present on the heatsinks of the main power board

while unit is on. Wait 40 seconds after removing power before handling.

Error code fault isolation

This section is for solving error codes appearing at power-up.

Faults resulting from user interaction or only during welding can be isolated using procedures

found in other sections identified below.

ERR 001 - TEMPERATURE FAULT

This section is to isolate a false digital temperature fault. This fault monitors the PFC

heatsink, main Inverter heatsink and main transformer.

Make sure that the system has at least 1 hour in un-powered state to cool down before

following these instructions.

A. With power applied, measure with DVMM the voltage between Control

Board 20AP1 CN19 pins 6 and 4 (ground). The voltage should be less

than 0.25VDC, if it is less than 0.25V replace Control Board 20AP1;

otherwise go to Step B.

B. (Hint: To prevent pin damage, use flat screwdriver to evenly remove wide

Control Board 20AP1 connectors).

Remove AC Mains power, remove Control Board 20AP1, and disconnect

15AP1 CN7 from Main Power board (PCB2/15AP1). Measure resistance

across CN7 plug. If it is not ~10K ohms, inspect plug connection or

replace Mains Transformer T1; If measurement is ~10K ohms, go to Step

C. Inspect Control 20AP1 CN19 cable assembly and measure resistance for

continuity between pin 6 of each end of the cable, it should be ~0 ohms; If

cable reads 0 ohms, inspect for dust or replace faulty 15AP1 Main Power

board (PCB2/15AP1); Otherwise repair/replace the Cable.

ERR - 002 - TEMPERATURE FAULT

This section is to isolate a false output diode temperature fault.

Make sure that the system has at least 1 hour in un-powered state to cool down before

following these instructions.

ERROR CODES

A. With power applied, measure with DVMM at 20AP1 CN19 pin 3 to pin 4

(Ground). If between 1.0 - 2.0 Vdc, then replace 20AP1 Control PCB;

otherwise go to Step B.

B. Turn off power, unplug Rebel from AC mains power, disconnect CN28

on 15AP3 AC/DC Board, measure resistance across CN28 connector

leads on the AC/DC Board PCBA.

If measured value is 10K +/- 2K ohms, then there is a cable issue, go to

Step C.

If measured value is not 10K +/- 2K, replace 15AP3 AC/DC Board.

C. (Hint: To prevent pin damage, use flat screwdriver to evenly remove wide

Control Board 20AP1 connectors). Reconnect 15AP3 CN28, measure

continuity between 15AP3 CN28 PCBA connector leads on the PCB and

20AP1 CN19 connector plug pins 3 and pin 4. If the continuity is not good

for either the black and red wires, or the black and red are shorted

together, inspect both wire harness #13989 and #14028 for damage. If

the cabling is good, replace the Main Power board (PCB2/15AP1)

15AP1.

Figure 1. Reference for Err 001 and Err 002

ERR - 003 - SYSTEM LOCKED POWER FAULT

This section is to isolate a persistent low voltage fault at power up when the unit is in standby

or idle mode. This fault can temporarily happen under heavy load conditions, in which case,

is a warning that the 400VDC bus voltage has momentarily gone below 350VDC due to

input mains voltage sag caused by low AC input voltage, long line length or thin gauge

extension cords, causing a excessive voltage drop before reaching the Rebel. For the

service personnel having this fault continuously at power up follow the below procedure.

ERROR CODES

A. Caution High Voltage Measurement: With power applied, measure on

15AP1 with DVMM the voltage between heat sink terminal at D50 and

R88 resistor lead. See Figure 2. - DC BUS Voltage Test Point on Power

Board. If voltage measured is 400 VDC +/- 10V go to Step B, if not go

section MACHINE DOES NOT POWER UP, (6) IPS CHECK.

B. With power applied measure between Control Board 20AP1 CN19 pins 5

and 4 (ground). The voltage should be less than 0.25VDC. If it is less

than 0.25V and the fault Error 4 persist, replace Control Board 20AP1;

otherwise go to Step C.

C. (Hint: To prevent pin damage, use flat screwdriver to evenly remove wide

Control Board 20AP1 connectors).

Remove AC Mains power, remove Control Board 20AP1. With 20AP1

removed, check continuity of pins 4 and 5 end-to-end across cable

assembly #14028. If cable is good replace 15AP1 Main Power board

(PCB2/15AP1) otherwise repair/replace cable assembly.

ERR 005 - PS LOCAL FAULT SERVICE REQUIRED

This section isolates Low Voltage of Internal Power Supply, IPS Error. This error code gets

set when the 24VDC supply is less than 22.5VDC. This can happen from overload from a

faulty peripheral, PCBA or wire feeder.

A. With power applied, measure with a DVMM 20AP1 CN2 between pins 1

and pins 7. If 23-24VDC is present replace 20AP1 Control PCB.

Otherwise go to step B.

B. Turn off power, disconnect the following 20AP1 connectors; CN7, CN9,

CN10, CN11, CN13, CN14. Reapply power, if the fault clears restore

connectors one at a time to isolate bad subassembly (fan, solenoid,

motor, etc). Otherwise go to Step C.

C. Turn off power, remove 20AP1 CN17 and CN19 of the Control PCB.

Reapply power, if the fault clears replace 20AP1 Control Board; otherwise

go to Step D.

D. Turn off power, remove 20AP1 CN2 of the Control PCB. Reapply power,

measure the voltage of plug sourcing 20AP1 CN2 between pins 1 and 7.

If the voltage is not ~24VDC replace 15AP2 IPS Board. Otherwise

replace 20AP1 Control Board.

ERR 006 - SET PCBA-20AP1 SW2.4 ON

This section isolates VRD Configuration Error. This Error happens when the VRD enable

switch 20AP1 S1.2 is enabled but VRD Capability switch 20AP1 S1.4 is disabled. Please see

"Control Board SW2 Positions", page10 for proper switch positions of S1 for non-VRD

use.

A. Check proper switch position (all off for non-Australian models), exercise

the switch leaving in proper positioin, check latest software is loaded.

B. If Step A checks good, replace 15AP1 Control Board.

ERR 007 - Reserved

ERROR CODES

0463 669 001

ERR 008 - VOLTAGE FAULT SERVICE REQUIRED

This error occurs when the OCK terminal voltage is not properly sensed when a voltage is

expected to be present, for instance when in MMA mode and the output is enabled. It takes

10 continuous second of no output to trip this fault. First attempt a software update to the

latest version before troubleshooting this fault.

A. Apply power, place unit in MMA mode, observe D33 on 20AP1 Control

Board (PCB3/20AP1) while enabling the output. Verify the green LED

flashes bright momentarily and remains on dimly. If the LED flashes or

stays on brightly go to Step B. If the LED does not flash replace 20AP1

Control Board.

B. With MMA enabled, measure the across OKC +/- terminals. If the voltage

is greater than 50VDC remove AC power with SW1 and perform the

following continuity cable checks: If voltage is ~0VDC go to section 'NO

WELD OUTPUT', step 9 to 13.

Check continuity of cable connection at PCB3/20AP1 CN1 pin 1 to XS1

(OKC+).

Check continuity of cable connection at PCB3/20AP1 CN1 pin 2 to

15AP3 TP39.

Check continuity of cable connection at 20AP1 CN15 pin 1 to XS2

(OKC-).

If any are not ~0 ohms repair/replace cable assembly.

If the cables connections are good replace Control Board (PCB3/20AP1).

ERR 009 - LOW INPUT

This section isolates persistent Low Voltage Error. AC Mains voltage is monitored at the

Control Board. This fault can temporarily appear under heavy load conditions, in which case,

this is a warning and not a failure. Weld performance is affected by AC input voltage droop.

Long input power cords can result in significant voltage drop when under heavy output loads.

For service personnel having this fault continuously, and at power up, follow the below

procedure.

A. Apply power and check AC voltage at 20AP1 CN19 across pin 10 and pin

11 for:

When connected to 120VAC check monitor voltage of 7.85 AC Vrms +/-

0.4.

When connected to 230VAC check monitor voltage of 15.0 AC Vrms +/-

0.75V.

The conversion factor is (AC Vrms IN/15.25).

If the voltage is correct, replace the 20AP1 Control PCB; otherwise go to

step B.

B. Turn off power, disconnect from wall outlet, and remove PCB3/20AP1

Control Board. Check continuity of cable assembly #14028 end-to-end of

pins 10 and 11.

Repair/Replace if cable is faulty.

If cable is good replace Power board (PCB2/15AP1).

Duty cycle

The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or

cut at a certain load without overloading. The duty cycle is valid for 40°C(104°F).

Enclosure class

The IP code indicates the enclosure class, i.e. the degree of protection against penetration

by solid objects or water.

Equipment marked IP 23S is intended for indoor and outdoor use; however, should not be

operated in precipitation.

Application class

The symbol indicates that the power source is designed for use in areas with increased

electrical hazard.
