Overview and Identification

BAPI Temperature Transmitters are 4 to 20mA output (loop powered) or 0 to 5VDC or 0 to 10VDC output transmitters. They come with flying leads but terminals are available (-TS).

1. Mount track with screws through the bottom of the plastic track.
2. Insert one edge of the transmitter, then snap the other edge in.

Wiring & 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 high or low-voltage AC power wiring. BAPI’s tests show that inaccurate signal levels are possible when AC power wiring is present in the same conduit as the sensor wires.

Diagnostics

Possible Problems:

|

Possible Problems:

---|---
• Unit will not operate.| – Measure the power supply voltage by placing a voltmeter across the transmitter’s (+) and (-) terminals. Make sure that it matches the drawings above and the power requirements in the specifications.
– Check if the RTD wires are physically open or shorted together and are terminated to the transmitter.
• The reading is incorrect in the controller.| – Determine if the input is set up correctly in the controllers and BAS software.
– For a 4 to 20mA current transmitter measure the transmitter current by placing an ammeter in series with the controller input. The current should read according to the “4 to 20mA Temperature Equation” shown below.
