DCModels
Outputs
l Out 1 - Out 6 - These are the terminals for the Two Wire 12V DC Latching Solenoids.
If a main valve or a delay valve has been designated during the controller’s configuration process,
it's solenoid's output will always assigned to output number 6 If a main valve and a delay valve are
configured the main valve will be assigned to output number 5 and the delay valve to output
number 6.
l Alarm - This output is a Dry Contact Relay (a free potential contact); it provides a command pulse to
an external alarm device. The alarm is activated in two cases:
l When selected number of consecutive flushing cycles have taken place due to continuous dif-
ferential pressure input signal, which usually occurs when the filters are clogged.
l When the battery voltage is lower than 4.7 VDC.
l End of Cycle - This output is a Dry Contact Relay (a free potential contact); it provides a command
pulse for 5 seconds and can be used to chain controllers. See "Chaining Controllers" on page40.
Inputs
See "Terminal Strips Drawings" on page11.
D.P.
This is the connection to the differential pressure switch.
Power Supply
6-12 VDC - The connection terminal of the DC models is used to connect, when available, a 7.2-12 VDC
1000 milliamp external power supply unit to the controller.
When an external power supply is connected, the internal batteries of the controller are used only for a
back up and not for the actual operation of the controller.

Outputs
l Out 1 - Out 6- These are the terminals for the Two Wire 24VAC Solenoids.
If a main valve or a delay valve has been designated during the controller’s configuration process,
it's solenoid's output will always assigned to output number 6.
If a main valve and a delay valve are configured the main valve will be assigned to output number 5
and the delay valve to output number 6.
