Lockout of Electrical and Pneumatic Energy
Lock Out/Tag Out of AC Power
WARNING! CAUTION!
Lock out and tag out electrical power and pneumatic pressure when performing
service or maintenance work on the dispensing system. Failure to do so could
cause serious injury to the user and/or serious damage to the dispensing system.
To lock out/tag out AC power:
1. Verify that all dispensing motion has stopped
2. Turn the Main Power Switch on the rear of the system to the
OFF (0) position.
3. Unplug the Main Power Cable from the facility source and lock it in a locked box.
4. Place a warning tag on the Main Power Inlet.
" NOTE Warning tags document the name of the technician taking the equipment out of
operation, the date, and other facility-required information. It is a warning that
the equipment cannot be put back into operation until the authorized technician
has removed the tag.
To lock out/tag out pneumatic pressure:
1. Verify that all dispensing motion has stopped.
2. Lock out and tag out AC power as specified earlier in this section.
! When the power is shut off, the Main Air Solenoid Valve shuts off and all air pressure
inside the dispensing system is automatically released.
3. Locate the Main Air Pressure Regulator adjustment knob.
4. Unlock the knob by pulling it out and then rotate the Main Pressure Regulator adjustment
knob counterclockwise until the Main Air Pressure Gauge registers 0 psi.
5. Disconnect the facility air supply hose from the Main Air Inlet and place a warning tag on the
Main Air Inlet.
Interlock
When the Interlock Circuit is open, the Interlock immediately stops all dispensing activity to protect the
operator from injury. The Interlock is an electronic connection to the motor processor and power, as well
as the Discreet and GP I/O and the Solenoid Drivers, that immediately cuts the power to any motion and
to any peripheral (I/O or solenoid driver). The intended use of the Interlock is to prevent physical injury
(to the operator) from system motion while the operator is in the work envelope.
The recommended use of the Interlock is with the Asymtek optional Enclosure (P/N 99-006136) and Start
Button Box (P/N 99-005922).
