The voltage free, normally open auxiliary contact of the fan contactor closes terminal seven and eight of the shaker timer after fan shutdown, initiating the ON-DELAY.
Following the initial ON-DELAY time, the ON-TIME will energize the relay for the time set and operate the shaker motor. The ON-DELAY and ON-TIME can be adjusted by the two potentiometers.
These dust collector timers are 75mm high, 45mm wide and 105mm deep, with a housing that will easily snap into a DIN rail.
A practical and easy to wire conductor connection is supplied via a sturdy, pluggable screw connection.
