determine if the motor is being overdriven. At the factory, these settings are set
and checked before shipment. Raising the overloads current value over the factory
settings or removing the overloads from the controls will inhibit the ability of the
controller to properly protect the motor. This setting should not be modified
without contacting the manufacturer first.
Transformer
The transformer steps the high voltage down to a usable low voltage for the control
components. It is protected with fuses on the primary side and circuit breakers on
the secondary side. Exchanging the short-circuit protection of the controller should
be exact one for one. Never increase the short circuit protection of the controller
without consulting the manufacturer first.
Adjustable Flush Interval Timer
This timer allows the end-user to define the minimum self-cleaning/flush cycle
interval time. This is very important to ensure efficiency of the filter system.
Standard factory setting is to initiate one self-cleaning cycle every day at a
minimum. This is a high performance timer with 8A contacts and the ability to set
the interval from 0.05 seconds to 60 hours.
Programmable Logic Controller (PLC)
The Programmable Logic Controller (PLC) is designed to handle all of the controls.
It is used to simplify the operation, thereby making the overall controller more
robust. It has a special program designed by Amiad for this filter system. Although
the software is available for download by the manufacturer, the program should not
be altered without the consent of Amiad to avoid equipment malfunctions.
Power On Light
This panel face LED light is for local indication that the power is on and the system
is running.
Flush Pushbutton
This panel face green pushbutton is used to initiate a system self-cleaning or flush
cycle, providing the operator with a local means of self-cleaning/flushing the
system.
Fault Reset Pushbutton and Light
This panel face red pushbutton and LED light is used to indicate when a fault has
occurred (see Fault Conditions section for more detail) and the pushbutton function
is used to clear a fault condition when the issue has been corrected and the system
is ready to resume normal operation.
