S2-9XXX Series Dispensing System IOM Manual Safety

Situations where LOTO practices might not be required are when troubleshooting electrical, pneumatic,

or hydraulic components or assemblies that make de-energizing the whole system impractical.

Troubleshooting or servicing the dispensing system while powered up and operating should only be

accomplished by fully trained and qualified personnel. There should always be a second person present

when performing maintenance on a system under power.

To lockout/tagout the electrical and pneumatic energy (Figure 2-13):

1. Turn the main circuit breaker on the rear of the system to the

OFF (0) position.

2. Unplug the main power cable from the back of the power manager.

3. Rotate the main air pressure knob counterclockwise until the gauge registers 0 kPa (0 psi)

and then disconnect the main air supply by the quick release fitting.

4. Install an approved, keyed lock on the locking flange of the main circuit breaker so it cannot

be turned on; tag it with an approved tag.

 Ensure that the owner, date, reason, and estimated time for repair are clearly marked on

the tag.

5. Install an approved lockout clamp and keyed lock onto the power connector so it cannot be

reconnected to the power manager and attach an approved tag.

 Ensure the owner, date, reason, and estimated time to repair are clearly marked on

the tag.

6. Install an approved lockout clamp and keyed lock onto the pneumatic fitting so it cannot be

reconnected to the main air regulator and attach an approved tag.

 Ensure the owner, date, reason, and estimated time to repair are clearly marked on the

tag.

 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.

WARNING! If your dispensing system is equipped with a heater, allow sufficient time for the

heater to cool prior to performing maintenance or service. Failure to do so may

result in serious burn injury.

2.16 Light Beacon

The light beacon is a device that displays system status and can warn the operator when fault conditions

exist. The beacon has red, yellow, green, and blue lights that can be solid or flashing. The beacon also has

an audible alarm. Table 2-4 provides possible reasons for each color indication.

Software and hardware share control of the beacon lights. Sometimes, hardware-driven displays override

those caused by software conditions and sometimes software-driven displays override. Safety critical

conditions always have priority. Flashing light software commands have priority over solid light

commands.

 NOTE Light beacon action can be custom configured using the beacon control feature. Refer to

the Fluidmove User Guide or Fluidmove Online Help for details.

See Section 7 - Troubleshooting for suggested recovery from common fault conditions.
