Disabling the Guns

All electrical or mechanical devices that provide an activation signal to the
guns, gun solenoid valve(s), or the melter pump must be disabled before
work can be performed on or around a gun that is connected to a
pressurized system.
1. Turn off or disconnect the gun triggering device (pattern controller, timer,
PLC, etc.).
2. Disconnect the input signal wiring to the gun solenoid valve(s).
3. Reduce the air pressure to the gun solenoid valve(s) to zero; then
relieve the residual air pressure between the regulator and the gun.
