Can Your Machines Start Automatically?


Have you ever been in a scenario where you or someone you know was working on a machine and it lost power? This could happen for a number of reasons: power outage, machine overload, disconnected plug or accidental trip of a breaker. If you don’t know why the machine shut off, what would be your first reaction? Could it be to open up the machine and investigate? Perhaps walk away until the issue is resolved? But what happens when the power is restored? If the machine has not been designed with power outage protection, it may start up automatically. Think of the potential serious outcomes of a machine starting up unexpectedly. Best-case scenario is that no one is inside the machine and someone notices and turns it off. Worst-case scenario is catastrophic.

CSA Standard Z432-04: Safeguarding of Machinery Section states that machines must have a means to prevent automatic restart when it is re-energized following an interruption in the energy supply. This can be attained by the use of self-maintained relays, contactors or valves.

There is a simple way to test if your machines have power outage protection. With the machine on and running pull the plug or turn off the disconnect, once the machine has come to a stop turn on the disconnect or plug the machine back in and take note if it starts back up again on its own. Common machines that are often missing power outage protection are small, manual machines such as band saws, table saws, drill presses and grinders.
