BAPI AD592 Termination And Troubleshooting

Termination
BAPI recommends using twisted pair of at least 22AWG and sealant filled connectors for all wire connections. Larger
gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes.
Do NOT run this device's wiring in the same conduit as AC power wiring of NEC class1 or NEC class 2, NEC class 3 or with
wiring used to supply highly inductive loads such as motors, contactors and relays.
BAPI's tests show that fluctuating and inaccurate signal levels are possible when AC power wiring is present in the
same conduit as the signal lines. If you are experiencing any of these difficulties, please contact your BAPI representative.
BA/592 (2 Wire) sensors
1. Install a 10K 0.1% resistor between the sensor
Output (terminal 2) and Ground (GND).
2. Make sure that the resistor is connected
between the analog input (A.I.) point and
Ground.
3. Connect the sensor Output to the A.I. point.
4. Connect the 5 to 30 VDC wire last.

All BA592 sensors will have the following information provided on a label:
Therm Reading_______
The actual temperature reading
according to a thermometer that is
certified traceable to recognized
standards by the National Institute of
Standards and Technology (NIST).
To correct the Sensor Reading, simply add the offset value to the sensor reading so that it equals the thermometer
reading.
e.g. Therm Reading 74.6
Correction: Add (+1.6) °F to the sensor for an accurate reading: 73 + 1.6 = 74.6°F
e.g. Therm Reading 75.4
Correction: Add (-1.6) °F to the sensor for an accurate reading: 77.2 + (-1.8) = 75.4°F

Specifications subject to change without notice.
Sensor Termination and Troubleshooting
BAPI does not recommend wiring the sensor with
power applied as accidental arcing may damage
the product and will void the warranty
BA/592-10K (3 Wire) sensors
1. All BA/592-10K (3 wire) sensors have a 10K
0.1% resistor built in.
2. Connect the Ground (terminal 3) wire first.
3. Connect the Sensor Output wire second.
4. Connect the 5 to 30 VDC wire last.
