Safety
2.1. 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.
2.1.1. 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.
2.1.1.1. 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.
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 (with a padlock) 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
valves.
5. When work is complete, remove all tags and restore the machine to its working state.
2.2. Maintenance
Only qualified and trained personnel should perform maintenance or repair.
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 will result in death or injury.
