Error Codes
FIG. 17: Error Alert Screen
Error Code Error Icon Cause Possible Solutions
E11
A key has been pressed for more than 30
seconds
•
Check shot controller for stuck key
•
Replace shot controller
E50
Linear sensor fault, often caused if in Learn
mode and piston position measured is out-
side the expected range
•
Check wiring and replace as necessary
•
Check linear sensor and replace as necessary
•
Learn mode will need to be used if linear
sensor is replaced
E52
Dispense valve is stuck open or one of the
material tanks is empty, leading to higher
dispensed quantity than requested
•
If dispense valve is stuck, the machine will auto-
matically attempt to release it
•
The amount dispensed will be more than
requested when this error occurs
•
Fill tank
•
Adjust E52 alarm delay time from setup
screen #4
E53
A piston stroke has taken more than 10 sec-
onds
•
Verify that the gun safety is off
•
Verify that the gun dispense valve is not stuck
closed
•
Verify adequate hydraulic or pneumatic pressure
to machine
•
Inspect for mechanical interference with the pis-
ton
•
Verify correct power to the proportioner piston
E54
This error code warns of the possibility of
inconsistent shots but will allow the
requested shot to occur. Shots requiring
less than 1/8 of a full piston stroke will trig-
ger this error code.
•
Request a larger shot
•
Verify that shot volume variation is ok
E55
A shot has been requested that is above the
maximum allowable amount.
•
Request a smaller shot
E56
Learn mode failed to learn piston travel
range because:
1) Piston did not move during Learn mode
2) Linear sensor failure
•
Repeat Learn mode
•
Inspect the linear sensor and replace as neces-
sary
