Disabling the Applicators

NOTE: Adhesive dispensing applicators are referred to as "guns" in some
previous publications.
All electrical or mechanical devices that provide an activation signal to the
applicators, applicator solenoid valve(s), or the melter pump must be
disabled before work can be performed on or around an applicator that is
connected to a pressurized system.
1. Turn off or disconnect the applicator triggering device (pattern controller,
timer, PLC, etc.).
2. Disconnect the input signal wiring to the applicator solenoid valve(s).
3. Reduce the air pressure to the applicator solenoid valve(s) to zero (0);
then relieve the residual air pressure between the regulator and the
applicator.
