Check Module

Check the module operation to verify if the module has
failed and needs to be replaced.

1.

Visually check for the presence of glue in the weep
hole (W). See

Figure 11

.

NOTE:

If glue is present, the module needs to be

replaced. See

Replace Module

on page

2.

Verify that the air pressure to the solenoid valve is
65-80 psi (0.44-0.55 MPa, 4.4-5.5 bar).

3.

Verify that there is air pressure to the motor, which
will verify that there is fluid pressure.

4.

Make sure the system is at the correct temperature.

5.

While looking in the weep hole, press the solenoid
valve manual override switch (M) to manually trigger
the applicator.

NOTE:

Look through the weep hole. If the rod moves,

the module is functioning properly. If the rod does not
move, the module needs to be replaced. See

Replace

Module

on page

6.

Remove the nozzle.

7.

Press the manual override switch to trigger the
module. If glue flows from the seat, the module is
functioning properly.

Check Nozzle and Module

Trigger the applicator without the nozzle to determine if
the nozzle of the module is clogged.

1.

Disable the applicator assembly. See

Before

Beginning Repair

on page

2.

Use a 1/2 in. wrench to loosen the nozzle and
remove it by hand.

3.

Connect the power and solenoid cable.

4.

Return the applicator back into operation.

5.

Trigger the applicator.

a.

If adhesive flows, clean the nozzle and reinstall

it on the module.

b.

If the adhesive does not flow, the module is

clogged and needs to be replaced. See

Replace Module
