3. SAFETY
3.1. General Safety Information
Do not work on the Protocol 3 controller without reading and understanding this
section which contains important information and warnings. Ignoring these
warnings can result in death, serious injury or damage to the machine and
product.
3.2. Lockout
Machine lockout places the Protocol 3 controller into a zero energy state and
prevents accidental machine start up. Always follow the Lockout Procedure
described in this Section before cleaning, maintaining, or repairing the Protocol 3
controller. An accidental start-up, while working on the Protocol 3 controller, can
result in serious injury or death.
3.2.1. Lockout Requirements
1. Every power source that can energize any element of the Protocol 3 controller
must be shut off at the closest possible power source. This includes air, water,
nitrogen and electricity, including the Disconnect Switch.
2. After energy sources are locked out, test to ensure circuits are de-energized.
3.2.2. Lockout Procedure with Despatch Products
Personnel authorized to lockout equipment must have the necessary locks to
perform the lockout.
1. Physically disconnect all electrical power to the machine or lockout the
appropriate breaker or disconnects.
2. Close all valves and bleed off any pressure.
3. Test for power by attempting a start with the machine controls.
4. Identify the Lockout Condition with a tag on the electrical disconnect and
pneumatic shut off valve.
5. When work is complete, remove all tags and restore the machine to its
working state.
