Pivoting the Applicator Modules

Before operating the system, pivot the applicator module to the required

position for application of variable pitch patterns.

NOTE: The applicators have typically pivot marks on the rotating disk that

are spaced in increments of 5. The reference marks are also provided on

the rotating disk.

1. Relieve the system hydraulic pressure. Refer to Safety.

CAUTION: Do not pivot the the applicator modules if the applicator is cold.

Pivoting the applicator modules when the applicator is not heated will

damage the O‐rings.

WARNING: System pressurized! Relieve system pressure before adjusting

the applicator. Failure to relieve system pressure can result in personal

injury.

2. Loosen the two hexagon head screws located on the back of the

applicator body.

3. Pivot the applicator modules to the desired position.

4. Tighten the hexagon head screws.

Operation

The applicator is now ready for operation.

Starting the System

Follow this procedure to start the system.

CAUTION: Risk of equipment damage. Nordson Corporation recommends

turning off the applicator air supply during system startup to prevent

unexpected pressure buildup in the module and applicator body caused by

the expansion of the cold adhesive as it melts.

1. Make sure the applicator air supply is turned off.

2. Turn on the melter and allow it to reach operating temperature. Refer to

your melter manual for details on the startup procedure.

3. Turn on the applicator air supply.

4. Turn on the solenoid valve power supply, enable any triggering devices,

and start the production line.

WARNING: System or material pressurized. Relieve pressure. Failure to

observe this warning may result in serious injury.

2. Turn off the pump and relieve hydraulic pressure. Refer to your melter

manual.

3. Turn off the melter. Refer to your melter manual for details on the system

shut down procedure.

WARNING: Hot! Risk of burns. Wear heat‐protective clothing, safety

goggles, and heat‐protective gloves.

4. Place a drain pan under all applicators.

5. Manually trigger the applicators until they are drained of hot melt material.

6. Turn off the solenoid valve power supply.

7. Turn off the applicator air supply.

8. Manually trigger the applicator solenoid valves to relieve applicator air

pressure.
