POWER FEED ERROR CODE CH RT
POSSIBLE C USE
(F ULT)
More than one control box has the
same group number.
There are too many objects in the
group.
More than one object of the same
equipment type with the same
group number and feed head num-
ber.
A wire drive unit has its DIP
switches set to zero. It is in a
group that has more than one
object.
The unit did not receive a recogni-
tion command from the power
source.
An attempt was made to repro-
gram the Control Box or the wire
drive unit, but the program did not
verify.
C UTION
POWER W VE 455/POWER FEED 10
RECOMMENDED
COURSE OF CTION
Make sure the group DIP switch
setting is unique for each Control
Box. See Installation section of
this manual.
A given group can support a max-
imun of seven objects. Remove
any objects over seven either by
changing the group DIP switch set-
tings or physically disconnecting
the "extra" objects. See Instal-
lation section of this manual.
Adjust the DIP switch setting to
make either the group number or
the feed head number unique for
all objects of the same equipment
type. See Installation section of
this manual.
The appropriate wire drive numbers
are 1 through 7. Check the DIP
switch setting chart in the Instal-
lation section of this manual.
Check to see if the STATUS LED on
the Power Wave 455 is not steady
green. If it is not steady green, refer
to the Power Wave 455 Status
LED Chart and Code Table.
Check the control cables for loose
or faulty connections. Also check
the continuity of all five leads from
one end to the other. The control
board in the PW 455 may be faulty.
Check for potential electrical high
frequency noise in the surrounding
area. Remove any potential HF
noise and program the unit again.
If the Err 020 still occurs, either
replace the EEPROM chip(s) in the
board being programmed or
replace the entire PC board being
programmed.
