Cause, Details
A key on membrane has been active (pressed) for > 30 seconds continuously.
Replace the HMI. This error code does not require user acknowledgment and
will clear itself automatically if the condition is removed.
The Display module has lost communication with the Fluid Control Module.
Material dispensing will be disabled if this condition exists. Check
communication cables between the 2 electronic components, or check the
HMI and/or the Fluid Control Module.
This error will be regenerated continuously while the condition exists.
The Run Token in the FCM is missing (not installed), or does not have the
correct data.
A piston stroke action has taken > 55 seconds. Typically caused by no/too
little air pressure to the machine or a mechanical interference with the piston
has occurred. Check machine input line pressure.
User has requested a shot < the minimum allowable size entered during
calibration. (< 15% of stoke, N/A in Operator Mode).
The calibration done on the machine is invalid, so the requested shot cannot
be executed. For instance, a Large Stroke Calibration Shot mass which is
less than the Short Stroke Calibration Shot mass (C4 screen) will create this
error code. If the wiring to the linear position transducer is reversed this error
will appear. If invalid piston positions are calibrated into the machine (C1
screen) this error will appear.
The piston velocity is slower than the calibration velocity measured, by the
percentage amount selected by the user (20%, 40% or 60%). If the user
selects 0%, this monitoring or alarm feature is disabled.
If generated, shot size accuracy may be degraded. Typically the problem is
created when the machine pressure regulator is adjusted to different value
from when the machine was calibrated. Another less likely cause could be a
mechanical failure with dispensing (worn piston, etc.). This error will not be
generated for a purge shot or when the machine is in Operator mode.

Tank A is low (only generated if tank sensing is enabled). Fill tank A with
material.
Tank level errors will be generated after every shot if the condition still exists.
Tank B is low (only generated if tank sensing is enabled). Fill tank B with
material.
Tank level errors will be generated after every shot if the condition still exists.
