The controller allows the user to adjust the flush duration, dwell time between backwashes, and the specified periodic backwash. Other features include manual start, counter reset, and alarm reset. MOV02 MOV02 MOV02 The controller receives an open/closed signal via terminals through 6. This signal is from the differential pressure gauge, and means that the gauge has reached a preset value. Reaching the preset value (usually 7 psid) tells the controller that debris has collected on the screen element, and that an automatic backwash will activate When a closed signal is sensed on terminals and 2 for a second period, the backwash sequence begins. The backwash sequence is: station energizes for the flush duration, then an idle period for the dwell duration, then station 2 energizes for the flush duration,. another dwell, and then station 3 energizes 2.

A differential pressure switch shall be arranged on the filter or across the inlet and outlet piping of the filter to override the timer in the TIME&DP mode or acting alone in the DP ONLY mode to initiate the cleaning cycle whenever a differential pressure across the filter exceeds a preset value. The differential pressure switch shall continue to operate the cleaning cycle until the differential pressure across the filter returns to normal or an adjustable timer inside the control panel elapses. If the cleaning cycle continues until this preset timer elapses, AutoEC3EPLC then the control panel shall shut down the cleaning operation completely causing the red alarm FAULT light to glow on the cover of the control panel Output and Terminals send for a Valves 24 volt (24VAC) AC alarm signal to terminals &6. 7 and Black 8 Lead inside () for Valves the, control 2 & 3 panel.
