Technical Data
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.
AC Models
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.
