AL_03
0x*2,0x*3,0x*6,0x*7
0x*A,0x*b,0x*E,0x*F
The input current is too
low.
Input at least 3.5mA
Insufficient
Input Signal
Range
AL_03
0x*4,0x*5,0x*6,0x*7
0x*c,0x*d,0x*E,0x*F
The input signal range is
too narrow.
Set the input signal span
more than 2mA.
Temperature
Out of
Range
AL_03
0x*8,0x*9,0x*A,0x*b
0x*c,0x*d,0x*E,0x*F
The temperature in the
device is lower than -40°
or higher than 80°.
Set the ambient
temperature to between
-40° and 80° as specified
by the usage conditions. If
this message is displayed
even though this condition
is satisfied, a sensor error
is suspected. Contact
Azbil group.
Supply
Pressure
Out of
Range
AL_03 0x1*,0x5*
The supply air pressure
detected in the device
is lower than 50 kPa or
higher than 715 kPa.
- Check that the supply air
pressure is applied.
- Set the supply air
pressure to 715 kPa or
lower. If this message
is displayed even
though this condition is
satisfied, a sensor error
is suspected. Contact
Azbil group.
Incorrect
Setting of
Input Range
High/Low
AL_03 0x4*,0x5*
The high and low setting
of the input signal range
are incorrect.
Make sure the sttings
of Input Range High
(Open)and Input Range
Low (Closed).
Supply
Pressure
High Alarm
AL_16 0x01,0x05,0x09
The supply air pressure
is higher than the
specified threshold value.
- Check the supply air
pressure.
- Check that the threshold
value is appropriate.
Supply
Pressure
Low Alarm
AL_16 0x02,0x06,0x0A
The supply air pressure
is lower than the
specified threshold value.
Temp High
Alarm
AL_16 0x04,0x05,0x06
The internal temperature
is higher than the
specified threshold value.
- Check the ambient
temperature.
- Check that the threshold
value is appropriate for
the usage environment.
