Changing Control Module
WARNING:
Hot! Risk of burns. Wear heat‐protective gloves.
CAUTION:
If some but not all of the control modules on an applicator are
replaced, the applicator must continue to be operated with lubricated
compressed air. Observe the instructions in the section
Installation
on
lubricating or not lubricating compressed air.
Nordson recommends keeping a supply of control modules to prevent
production stoppage.
CAUTION:
The control module is a high precision, valuable part. Handle
very carefully!
Removing Control Module
1. Disconnect air hoses.
2. Heat the applicator until the material is soft.
3. Release the four screws (M4) and extract the control modules from the
warm applicator.
Installing Control Module
NOTE:
Required tool: Torque wrench.
1. Apply high-temperature grease (Refer to page

S
To the O-rings,
S
To the screw threads
S
Under the screw heads.
2. Insert the new control module carefully, taking care not to tilt it.
NOTE:
When the control module is slid into the body, the two O‐rings cause
some resistance that must be overcome. When the part with the detection
holes is on the body, the control module has been slid in far enough.
3. Screw in the four screws (M4) by hand. Do not tighten!
4. Tighten the screws crosswise in three steps of 0.9 Nm each. Use a
torque wrench.

non‐lubricated operation.
6. Re‐connect air and electrical connection.
