TROUBLESHOOTING

When no alarms are detected

When no alarms are detected::::

POWER lamp does not illuminate.

Fault status

Probable cause

Corrective action

Circuit breaker for the
Welding power is
tripped.

Incorrect R.S.T. wiring
connections.

Check the cable connection
referring to Section “2
INSTALLATION AND CONNECTIONS”.

Poor contact of the
connector
(CN2) in the timer.

Check the connector.

Faulty POWER lamp.

Replace the POWER lamp.

Circuit breaker tripped.

Reset the circuit breaker.
Check the cable connection
referring to Section 2.

Power cable is normally
connected.

Circuit protector on the
board tripped.

Press the button above the
circuit protector.
Check the cable connection
referring to Section 2.

Conduction is not triggered in spite of Start SW.

Fault status

Probable cause

Corrective action

Break in DeviceNet
communication cable.
Connector dislodged.

Check Timeout Error, then
check the cable and replace, if
required.

Parameter “Pq Remote
I/O” set to OFF,

Set the parameter “Pq Remote
I/O” to ON.

Check the timer mode
setting.
Check for No Weld or
Conti. Press. mode.

Check the setting using the TP-NET.

DeviceNet timer input
“Conduction On” not
set to ON.

Check the DeviceNet communication
data.

Break in wiring or cross
wiring

A17-B17

safety SW in the TB1
terminal block.

Check the wiring.

Solenoid valve wiring is
normal but solenoid
valve not actuated

Faulty solenoid valve. Replace
the valve.
