Error Codes
When errors occur, press to acknowledge each error. After being acknowledged, the error will clear automati-
cally when the condition that caused it is corrected. Active errors scroll on the menu bar.
Alarms shut down the pattern controller and activate the dry contact PLC output. Advisories and deviation are infor-
mational only and do not shut the system down.
Alarms (shut the system down)
Code Description Cause Solution
CAXP Communication error ADM unable to communi-
cate with pattern control-
ler
Check for green power light on the pattern controller
Check communicating cabling
A40P Over-current Over-current on trigger
and/or run up power sup-
ply output (pins identified
by "+" on control board)
Check accessory cabling for short circuit.
A4XP Over-current Over-current on commu-
nication cable output (P3
on control board)
Check ADM CAN cabling for short circuit
Replace display (ADM)
A4_P Over-current Over-current on valve
output “_”
Check wiring for short circuit
Verify valve resistance is higher than 24 ohms
K4_P High pulse rate Encoder “_” pulse rate
exceeds maximum limit
Select encoder with lower pulse rate
Reduce line speed or gearing ratio
Advisories and Deviation (do not shut the system down)
Code Description Cause Solution
V1_P
or
V2_P
Low voltage Power supply voltage below 18
VDC
To check for overloaded power supply, measure the voltage
with all valves off, and then with all valves on (purging)
To check for overheated power supply, allow the unit to cool
and recheck voltage
Adjust voltage to 24 Vis possible, or replace the power supply
V3_P
or
V4_P
High voltage Power supply voltage above 28
VDC
Adjust voltage to 24 V if possible or replace the power supply
K1_P Low line
speed
Poor encoder coupling on line
“_”
Check to ensure proper coupling between line and encoder.
Verify pattern controller is reading appropriate line speed.
See Line Mode, page 30.
Line speed is less than low line
speed alarm level on line “_”
Increase line speed or decrease low line speed alarm level.
See Line Mode, page 30.
EBTX PC-8e token
removed
Missing or loose PC-8e token If missing, re-insert PC-8e token. If present, check for loose
connection.
