Problem
Presumable cause
Confirmation
No light on
power LED
and
other LEDs
・Power not supplied
・Power specification is
changed from the
ordered specification.
・Circuit protector is OFF.
・CPU abnormal.
・Confirm power supply voltage on Circuit protector terminal
base.
・Confirm the voltage on name plate of Transducer is the same
as the supplied power.
If it is different, return us Transducer, then the power spec.
will be changed at out site.
・Switch Circuit protector to ON.
・Power OFF, then ON.
Instable
output
indication
・Warm up operation after
setup is not complete.
・Unconnected between
Sensor and Converter
・The wiring between Sensor
and Transducer is either
off or wrong.
・Material sticking on
Probe electrode.
・Condensation on
electrode
・Micro amount solid
particles flying.
・Make warm up operation for 1 hour and check output again.
・Confirm cable connection between sensor part and converter.
If unconnected, please contact us.
・Confirm wiring of exclusive cable.
(See Page 4, 5.Connecting.)
If wiring is wrong, rewire correctly.
・Remove Sensor and check if any sticking on Probe electrode.
If yes, power off and wipe them off with moist cloth. (See NOTE)
・Remove sensor and confirm electrode.
If condensation on electrode, wipe off with a wet rag after
power-OFF. (See NOTE)
・Change measuring sensitivity or integration setting.
