Turn On Delay - IVAC Pro Guía Del Usario

4.3 Turn On Delay

Upon receiving a command from a 'Tool Plus' unit to turn on
the power to a dust collection system, there is a delay of 1.5
seconds before the power is turned on. This delay is to avoid
two power surges occurring at the same time on an AC mains
circuit that is feeding both the power tool and the dust
collection system. This feature is to avoid tripping the main
circuit breaker.
