FMS BAPI Temperature/Humidity Falcon Integration
Temperature Setup
Humidity Setup
1. Wire the sensor as shown.
5. Verify the "Calc" Value displays the correct room temperature.
The temperature can also be viewed on the Falcon main page.
SETUP
1. Calculate the BAPI Output current for temperature.
TROUBLESHOOTING
2. Measure the current flowing into the Falcon Ch- terminal with a
current meter. Verify that it is close to the calculated current
(+/-1%)
3. If measured current current does not match calculated current
then check wiring and check the BAPI switch settings.
4. Compare the measured current matches the current reading in
the Falcon.
5. Check the wiring if the Falcon current reading does not match
the measured current reading.
6. If the Falcon current reading matches the measured current
and the Falcon calculated value does not match the room
temperature then the offset and gain values are wrong.
Double check the Gain and Offset values.
7. If the temperature displayed in the Falcon is 1 or 2 degrees
above or below the room temperature then adjust the offset by
1 or 2. Do not adjust the gain. Only tweak the offset once the
previous troubleshooting steps have been performed.
8. If the Falcon still does not display the correct temperature
contact RLE Technologies technical support at 970.484.6510.
9. Use similar troubleshooting procedure except use the
following formula to calculate the humidity mA output.

2. Configure the Falcon Input channel (temperature) for "Analog
4-20mA" and enter the gain and offset values. For the 32-
120F range use Gain 22, Offset -10.
4. Configure the Falcon Input Channel (humidity) for "Analog 4-
20mA" and enter the Gain of 25 and Offset of -25.

Example if Room Temp is 70F and your sensor has a range of 32-120
( (Actual temp - Sensor Low) / (Sensor High - Sensor Low)) x 16 + 4
( (70 - 32) / (120 - 32)) x 16 + 4 = 10.90
32 - 120 Degree F Range
