Operation

Before operating the system for the first time, ensure that you have

completed the procedures in the Installation section.

Special Operating Considerations for PUR Adhesive

The viscosity of PUR adhesive increases significantly when the system is at

operating temperature, therefore the applicator should be heated only for

operation or cleaning. If the applicator is held at operating temperature longer

than the life of the PUR adhesive, then the risk of cured material inside the

applicator increases.

However, even in the best operating scenario it is still likely that over time the

PUR will occlude the inner adhesive passages, requiring the applicator to be

cleaned. When the applicator is cleaned, is it critical to remove cured PUR

adhesive from all adhesive passages, not just the adhesive passages inside

the module.

Daily Start‐up and Operation

1. Turn on the robot.

2. Turn on the controller. The controller display will go through the start-up

screens.

NOTE: The controller always powers on in the user mode.

3. Turn on the air supply.

4. Allow the system to reach application temperature.

5. If a cured adhesive warning exists at start-up, reset the Elapsed Time

parameter to 0.

6. Verify that the temperature settings are at the desired value.

Respond to Alarms

Refer to Troubleshooting for a list of alarms and recommended corrective

actions.

Place the System in Setback

Refer to the Flexseam controller manuals for more information.

Monitor the System

Refer to the Flexseam controller manuals for more information.

Shutdown

PUR adhesive reacts with moisture in the air therefore exposure of the PUR

adhesive in the system to air must be minimized. The procedures below

represent the best practices for overnight or long‐term (longer than overnight)

shutdown.

Overnight Shutdown

1. Shut down the system and allow the applicator to cool, leaving the

current syringe/cartridge in the applicator. This will retain the seal and

minimize the exposure to air.

2. The next morning, follow the Daily Start-up and Operation procedure

earlier in this section to install a new syringe/cartridge.
