Overview
6
The BA/T100 units are 4 to 20mA loop powered transmitters that can be ordered with separately purchased 100Ω (385)
platinum RTD. The BA/T1K units are 4 to 20mA loop powered transmitters that can be ordered with separately purchased
1KΩ (385) platinum RTD. The BA/T10K units are 4 to 20mA loop powered or 0 to 5VDC or 0 to 10VDC transmitters that can
be ordered with separately purchased 10K-2, 10KΩ type 2 thermistors. T100 and
terminals are available (-TS). Terminals are not available on the T10K units.

Wiring & Termination
6
BAPI recommends using twisted pair of at least 22AWG and sealant lled 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.

Possible Problems: Possible Solutions:
•

temperature standard. Disconnect the temperature sensor wires and measure the
temperature sensor’s resistance with an ohmmeter. Compare the temperature sensor’s
resistance to the appropriate temperature sensor table on the BAPI web site.
• The reading is incorrect in the controller.
- For a 4-20mA current transmitter measure the transmitter current by placing an ammeter
Voltage Temperature Equation
T = TLow + (V x TSpan)
VSpan
T = Temperature at sensor
TLow = Low temperature of span
THigh = High temperature of span
TSpan = THigh - TLow
VLow = Low transmitter voltage
usually=(0, 1 or 2v)
VHigh = High transmitter voltage
usually=(5 or 10v)
VSpan = VHigh - VLow
V = Signal reading in volts
- Determine if the input is set up correctly in the controllers and BAS software.
in series with the controller input. The current should read according to the “4-20mA
Temperature Equation” shown below.
- For a voltage transmitter, measure the signal with a volt meter (Orange or Orange/Black to
Black). The signal should read according to the “Voltage Temperature Equation” shown below.
4-20mA Temperature Equation
