Replacing Control Module
Nordson recommends keeping a supply of control modules on hand to
prevent disruptions in production.
NOTE: Replace only when control module is warm and material is soft
(approx. 70 °C / 158 °F, depending on material).
WARNING: System or material pressurized. Relieve pressure. Failure to
observe may result in serious burns.
1. Disconnect air supply and electrical connection.
2. Release screws M5 and extract control module from the warm filling
valve.
3. Put new control module in place and tighten screws crosswise.
4. Re-connect air supply and electrical connection.
NOTE: Observe voltage shown on solenoid valve ID plate.

4 to 6 bar
400 to 600 kPa 58 to 87 psi
The quality of the compressed air must be at least class 2 in compliance
with ISO 8573−1. This means:
