FUNCTION PROBLEMS
White Power On light does
not light up.
1. Main Switch is in off position
2. No power supply
3. Fuse(s) defective Turn on main switch
1.Check power supply.
2.Check for normal component operation.
3.Are green power lights illuminated on PLCs and components? If
not, replace.
4.If any components replaced were Smartwire, the green LED will be
flashing and the "Learn" process has to be done before the
component(s) are recognized, and the unit will operate
Cleaning cycle is not
functioning.
1. Possible bad connection between
control box and junction box.
2. Possible bad electrical connection.
3. Possibly no or low compressed air.
1. Verify that the Fan running LED (Green) and the white power on
light is illuminated. A green LED comes on on the Eaton 4DD I/O pack
when the output comes on, a flash should be seen as the valve is
pulsed on to create the air blast during an active cleaning cycle.
2. Verify the correct input voltage is being applied.
3. Verify that all fuses and circuit breakers are not blown/tripped.
4. Verify that the LED’s on the Eaton Smartwire I/O pack are
illuminated, on solid green is good, flashing means the IO pack has
power but is not recognized by the system. Find the "learn"
smartwire function reference in the manual. During a cleaning an
output LED flashes on for the I/O pack, it sends a 24VDC pulse to the
air valve. Check the cable connection from the valve to the I/O pack,
to confirm a working valve or I/O port swap cables on outputs.
5. Verify compressed air is present and with adequate pressure.
Cleaning valve fails to open. 1. The pulsation cycle may be faulty.
2. Possible dirt in the housing of the
valve.
3. Possible incorrect flow direction on
the cleaning valves.
4. Possible incorrect control voltage for
the magnetic valves.
1. Verify that the pulsation cycle is OK, that it's within the parameters
recommended by Lincoln Electric.
2. Clean the housing of the valve.
3. Verify that the airflow directions on the cleaning valves are in
accordance with the airflow.
4. Verify that the cleaning system is working properly - 87 PSI (6
BAR)
5. Verify that control voltage for the magnetic valve is 24V DC and
connected at the Eaton SWD4-SFL8-12 flat to round cable converter
at terminals X2-24V and X2-0V. This power is what goes out to the
4DD IO packs to activate the valves..
Cleaning valve fails to close. 1. The pulsation cycle may be faulty.
2.Possible dirt in the housing of the
valve.
3. Possible incorrect control voltage for
the magnetic valves.
1. Verify that the pulsation cycle is OK, that it's within the parameters
recommended by Lincoln Electric.
2. Clean the housing of the valve.
3. Verify that the cleaning system is working properly - 87 PSI (6
BAR)
4. Verify that control voltage for the magnetic valve is 0 Volts.
