2. Safety
2.1. Safety Information
Do not work on the Protocol Plus 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.
2.1.1. Lockout
Machine lockout places the Protocol Plus 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 Plus controller. An
accidental start-up, while working on the Protocol Plus controller, can result in serious
injury or death.
2.1.1.1. Lockout Requirements
1. Every power source that can energize any element of the Protocol Plus controller
must be shut off at the closest possible power source. This includes air, water and
electricity, including the Disconnect Switch.
2. After energy sources are locked out, test to ensure circuits are de-energized.
2.1.1.2. 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.
Danger!
Electrical panels contain high voltage. Disconnect and lock out
the power supply before working inside any electrical panels.
Failure to lock out the power supply can result in death or injury.
