3. The LED meter indicates the FWF duration
in 2 minute increments and adjustable range
is between 1 and 17 minutes. If R71 is set to
less than 60 seconds (i.e. turned fully counter
clockwise for 20 turns) then the FWF function
is disabled.
g) “Start” switch is depressed but the system
does not attempt to start:
Fault LED lamp is illuminated and requires
resetting by pressing Fault Reset Switch at the
touch pad.
Power Source Line is switched off, reset the
Power Source Circuit Breaker.
Blown fuse in the controller, check fuse
condition.
Micro Processor has locked up due to a
voltage spike from the Power Source. Turn
power off for a minimum of 20 seconds to
reset the Micro Processor.
Power source is dropping below the industry
standard of 15%, at the instant of starting,
preventing the electronic circuit from latching.
Check the power source to ensure that it
continually delivers the proper power to the
System. If voltage drops below acceptable
standards for even a micro second this causes
the electronic circuit to not latch.
Controller is wired improperly or there are
loose wires, check wiring with proper wiring
diagram
Start switch at the touch pad is defective and
not closing to make the circuit.
h) “Stop” switch is depressed but the system
does not attempt to stop:
Micro Processor has locked up. Turn power
off for a minimum of 20 seconds to reset the
Main PCB.
Stop switch at the touch pad is defective and
not closing to make the circuit.
Water damage to the printed circuit board
is shorting the stop circuit and causing the
system to remain in operation.
i) Fuse in controller blows at start up:
Low or high voltage into the system, correct at
the source into the system.
Defective component that relies on the fuse for
power:
- 3-way solenoid valve
- U.V. Sterilizer
- Printed Circuit Boards
- Touch Pad
- Shorted wire, locate shorted wire and
repair it.
