Replacing Control Module

Nordson recommends keeping a supply of control modules on hand to

prevent disruptions in production.

NOTE: Replace only when the control module is warm and the material is

soft (approx. 70 °C / 158 °F, depending on material).

WARNING: System and material pressurized. Relieve system pressure.

Failure to observe can 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.

Control air pressure:

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:

S Max. particle size 30 mm

S Max. particle density 1 mg/m

S Max. pressure dew point − 40 °C

S Max. oil concentration 0.1 mg/m
