Stuck Key Error

E11

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.

 

 

 

 

 

Communication

E12

The Display module has lost communication with the Fluid Control Module.

 

Error

 

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.

 

 

 

 

 

No or Invalid Run

E13

The Run Token in the FCM is missing (not installed), or does not have the

 

Token Error

 

correct data.

 

 

 

 

 

Piston Stroke

E21

A piston stroke action has taken > 55 seconds. Typically caused by no/too

 

Time-out Error

 

little air pressure to the machine or a mechanical interference with the piston

 

 

 

has occurred. Check machine input line pressure.

 

 

 

 

 

Less than

E23

User has requested a shot < the minimum allowable size entered during

 

Minimum Shot

 

calibration. (< 15% of stoke, N/A in Operator Mode).

 

Requested Error

 

 

 

Improper

E24

The calibration done on the machine is invalid, so the requested shot cannot

 

Calibration Error

 

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.

 

 

 

 

 

Delta Velocity

E25

The piston velocity is slower than the calibration velocity measured, by the

 

(“V”) Minus Error

 

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.

 

 

 

 

 

Delta Velocity

E26

The piston velocity is faster than the calibration velocity measured, by the

 

(“V”) Plus Error

 

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.

 

 

 

 

 

Low Material

E27

Tank A is low (only generated if tank sensing is enabled). Fill tank A with

 

Level, Tank A

 

material.

 

Alarm or Error

 

Tank level errors will be generated after every shot if the condition still exists.

 

 

 

 

 

 

 

 

Low Material

E28

Tank B is low (only generated if tank sensing is enabled). Fill tank B with

 

Level, Tank B

 

material.

 

Alarm or Error

 

Tank level errors will be generated after every shot if the condition still exists.
