ALARM ON SCREEN
No 4-20mA Sig 1
Coil Current Low
High Humidity
Coincell Bat Low
Low Voltage
Conv Msg Timeout
DESCRIPTION
4-20mA circuit is enabled but not able to
run current.
The current running on the coils to
produce the magnetic field is not able to
meet the desired value.
Humidity sensor reading above set
threshold
Coincell battery voltage low
There is a power issue between the
converter and transmitter.
There is a communication issue between
the converter and transmitter.
Check circuit wiring and voltage on circuit.
Disable the output if not in use to remove
alarm.
Check for coil current and resistance on
diagnostic screen page 2. Coil current
should be between 100-200. Coil resistance
should be less than 210. If there are no
values shown there, thenc heck coil wiring
on terminal block pins 11-14 at converter
PCB for a loose or missing wire. if wire
connection is good, then the problem is
located in the sensor body, contact factory.
Check converter housing on sensor for
any water ingress. Retighten housing lid.
Humidity reading may take some time to
drop down below threshold of 80%RH.
Converter temp and RH readings can be
found on diagnostic screen page 2. If alarm
persists, contact factory.
Check for a coil cell battery on the
transmitter. If present, try removing and
cleaning off both sides of the coin cell and
re install. Power cycle transmitter to confirm
coin cell voltage is checked. If still low,
contact factory for replacement.
Check sensor cable connector terminal
block on transmitter (pins 15-19) for a
loose or missing connection. Check wiring
diagram for correct pinout. Check the
length of the cable to the sensor for any
cuts or disconnects. Check input power to
the transmitter. Power cycle the transmitter.
If problem persists, contact factory.
Check sensor cable connector terminal
block on transmitter (pins 15-19) for a
loose or missing connection. Check wiring
diagram for correct pinout. Power cycle
the transmitter. If problem persists, contact
factory.
