Error Codes — Err 1
(Cont.)
Check 2
If spray head is still not functioning, check that your
24 VDC supply voltage is ok. If no Green LED or blinking
Red LED codes are displayed, it is a sign that there may
be an issue with the 24 volt supply.
Check that the 24VDC circuit breaker is not tripped.
If tripped, the connection is not closed and there will
be no 12 volt power supplied to the 24 volt converter,
resulting in no 24 DC volts. Check that connections are
clean and secure, reset breaker if necessary and retest.
(To reset the 24 VDC breaker the main power must be
removed by switching off the 50Amp main on/off
breaker momentarily.) Other breakers are reset by
pushing in the black button located on the top of
the circuit breaker.
If the 24 VDC breaker is not tripped and it has been
verified that 12 VDC is being supplied to the 12-24 VDC
converter, yet there is no 24 VDC present, check the on
board 20 amp fuse found in the upper right hand corner
of the converter.
If the on board 20 amp fuse is not blown and previous
checks have been verified, it may be that the converter
is defective or damaged. Replace the 24 VDC converter.

Check 1
The spray head must be turned on and spinning
within the rpm limits (23,400 - 30,000 rpm) for the
pump to be activated. This ensures proper droplets are
formed when fluid is delivered to the sleeve. The pump
can be activated with spray head off when in Cal Mode,
see section on Calibration for detailed instruction.
Check 1a
Visually inspect pump.
Turn pump coupler manually with your fingers. Does
pump turn?
If yes, go to Check 1b.
If no, go to Check 2.
Check 1b
Check white wire voltage from pump speed sensor.
If 5 volts present, check voltage at red wire and rotate
motor and inspect voltage. If it fluctuates, sensor is likely
good. If not, replace sensor.
Check 2
Disassemble pump from motor and replace frozen
component. Contact Clarke technical service
for assistance.
