3. Product Description
This Amiad controller enables users to have powerful filter controls in a compact
design. It is available in a wide array of power classes and voltages to meet the
needs of the market. The initiation of the Amiad filters’ self cleaning systems is by
a signal from a differential pressure switch measuring the pressure of the filter inlet
and outlet, a timer, control panel pushbutton for manual start or a remote start
input.
The system is designed specifically for each customer’s needs. Refer to the
drawings/schematics or electrical data plate on the side of the enclosure to
determine the largest motor which can be used and specific technical data.
3.1 Functional Description
Utilizing a start command (as described in the Product Description) for the self-
cleaning cycle, the system is designed to be self-sufficient. There is no need to
interfere with the filter as the equipment uses the highest level of technology to
control the filter system. Typical start command is given by a differential pressure
switch, however a variety of inputs are available for different applications. Consult
with your local Regional Sales Manager or Application Engineer for more details on
the best controller options for your application.
3.2 Standard Component Description
The following is for the standard controller configuration. Additional control options
are available and may enhance the capabilities of your controller. All components
are, UL approved, and conform to most international standards.
Disconnect Switch
This disconnect switch is for power isolation. It’s capable of handling up to 600V
AC.
Contactor and Overloads
The contactor and overload allow the end-user to have full control over the
pump/drive motor. From the factory, the pump/drive motor is controlled to either
turn on or off with the self-cleaning cycle as appropriate, but is easily modified to
accept different logic schemes. The overloads use solid-state technology to
