•
Damaged connection from the current sensor (see picture
below) to J24 of the FACS Input board 750-649-045.
•
Missing power supplies at current sensor. Check at J24
of the FACS Input board 750-649-045 for +15VDC (pin 18)
and -15VDC (pin 6).
8.3.6 E006 Input Voltage Too High
Fatal, meaning you have to power down to continue welding
>> Yes
Acknowledge, meaning the error will exist as long as the unit
is powered on. (Note, welding can continue while the error
exists)
>> No
Description:
When power is initially applied to the system, it goes through a series
of relay closures / opens and watches the primary voltage closely. If the
voltage is sensed to be a damaging level (>470VDC on the capacitor
banks - J1 on each switch board of the N1500i, J1, J4), the relays are
turned off and this error is displayed. They system must be powered
down and examined/ fixed prior to anything else.
Likely problems or items to check - in order from most likely to least
likely:
1. Measure the primary AC voltage and make sure it is
within the correct range for the system and the voltage
setting. The DC voltage on the switch boards must be
between 225VDC and 470VDC..
2.
Improper adjustment of voltage-to-frequency circuit to
switch board. Each switch board (1 board in the case of
the N800i) has a pair of wires to provide an open-collector
signal to the FACS input board.
