System Overview
The AMC Flushing Controller is pre-configured according to the filtration system’s types to be
controlled. This provides easy setup and operation and ensures reliable long-term operation. The
AMC Flushing Controller controllers are housed inside ABS enclosures and are designed for outdoor use
(IP 65).
The AMC Flushing Controller can control either 6 or 12 solenoids allowing them to operate six default
flushing programs covering a wide range of filters.
The operation method of each program is similar, however the timings of the various operation stages
vary according to the program.
The controller supports the following flushing processes:
l
Differential Pressure (DP) signal
l
Time Interval parameter
l
Manual Start command
The controller is also capable of controlling the following additional functions:
l
Main/Downstream Valve - (replaces one of the 6 filter units outputs) one of the controller's
outputs operates as a main or downstream valve. Downstream Valve is usually installed at the
outlet port of the filtration system. It is energized during the back-flush process to ensure sufficient
water pressure during flushing. A Main Valve enables the operation of a valve or a pump (through a
dry contact latch relay) for increasing the pressure or supplying additional water source during the
flushing process.
Note:
If a pump is connected to the Main Valve output, it is important to make sure that the relay
operating the pump control loop draws no more than 0.5 Ampere from the Main valve
output.
l
Delay Valve (replaces one of the 6 or 12 maximum filter units outputs) - one of controller's out-
put operates as a Delay Valve together with the flushing filter. For example, delay Valve can be used
for sampling the flushing water or for controlling an air-pressure operated back-flush system.
l
Alarm output - a special dry contact output (up to 0.2 Ampere) that is switched on in case of a sys-
tem fault.
l
End of cycle chaining output - a special dry contact output (up to 0.2 Ampere) that is switched on
for 5 seconds at the end of each flushing cycle. This output can be chained to the DP input of
another controller to start a flush cycle sequentially after the first controller.
