Safety Instructions
General Safety Instructions
lUse the controller only for its intended use as designed by the manufacturer, any misuse of the
controller may lead to undesired damage and may affect your warranty coverage. Consult with the
manufacturer prior to any non-regular use of this equipment.
lThe terminals enclosure lid of the unit must remain closed at all times.
lOnly a qualified technician may remove this lid and only when the controller is properly disconnected
from its power source.
lServicing the unit can be done only by qualified technician.
lMake sure that the filters controlled by the controller are disconnected from the water system whenever
servicing the controller.
lIn case the controller is connected to an external AC power supply unit, make sure that the power
supply connection is done only by a licensed electrician and the connection complies with your local
standards for High Voltage out-doors connection.
lPlease note: The filter enters into a flushing mode automatically, without early warning.
lNo change or modification to the equipment is permitted without a written notification given in advance
by the manufacturer or by its representative, on the manufacturer’s behalf.
lAlways observe standard safety instructions and good engineering practices whilst working in the filter’s
vicinity.
Electricity Instructions
lElectric wiring should be performed by an authorized electrician only, using standardized and approved
components.
lInstall a lockable main power cut-off switch close to the control panel.
lIf due to site constraints, the control panel is installed without a clear line-of sight of the filter, an addi-
tional lockable power disconnect cut-off switch should be installed near each filter unit.
lUse only the built-in transformer.
lIn case the controller is supplied with a power supply cable connected to it, the controller is for indoor
installations only!
lIn order to use the controller for outdoor installation, a licensed electrician must disconnect the power
supply cable, and connect the controller according to the instructions given in the installation chapter of
this document and in compliance with all the safety instructions and the local standards for High Voltage
out-door connection.
lIf the plug does not comply with your local regulation, it must be replaced with suitable plug by licensed
electrician only.
lHazardous Live voltages connected to the following output terminals :
lFilter Motor Control terminal (230VAC/115)
l24VAC for solenoid control and for 24VAC auxiliary (24VAC IS CONSIDERED HAZARDOUS LIVE IN WET
LOCATIONS!).

lBe careful while doing installation and maintenance of the filter flushing system Make sure that the
protective earth is well connected to the input terminal and to the motor body
lIt is necessary to connect a two-pole switch between the power supply and the controller, 115VAC or
230VAC depends on the actual controller model.
lThe supply point 115VAC or 230VAC (depends on the actual controller model), the circuit and connection
to the transformer must be performed according to “Field Electrical Regulations” by a licensed electrician
who is accredited with a license according to the Electrical Bill and security requirements.
lWhen using an internal transformer, minimal wire diameter must be 0.7mm. Check with standard
measuring equipment that there is no voltage in the electric circuit.
lNever cut, connect, or disconnect any wire at the controller’s vicinity.
lMake sure that the controller is not exposed to water splashes.
lKeep the keyboard cover closed at all times when not using the keyboard.

Introduction
The AMC Flushing controllers are electronic devices capable of controlling the back-flush process of
various automatic filter models installed in various configurations.
Galcon provides the AMCFlushing controller in the following configurations:
lDC controller
l115 VAC/230 VAC controller
Each controller has two solenoid configurations: 6 and 12 solenoids.
This document describes the configuration and operation procedures of the controller.

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:
lDifferential Pressure (DP) signal
lTime Interval parameter
lManual Start command
The controller is also capable of controlling the following additional functions:
lMain/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.
lDelay 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.
lAlarm output - a special dry contact output (up to 0.2 Ampere) that is switched on in case of a sys-
tem fault.
lEnd 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.

DCModels
Outputs
lOut 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.
lAlarm - 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:
lWhen 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.
lWhen the battery voltage is lower than 4.7 VDC.
lEnd 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
lOut 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.
lAlarm - 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:
lWhen a selected number of consecutive flushing cycles have taken place due to continuous dif-

lEnd 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.
