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. BAPI’s tests show fluctuating and inaccurate
signals are possible when AC power wiring is in the same conduit as the signal lines. If you are experiencing any of these
difficulties, please contact your BAPI representative
.

Circuit Board
BAPI recommends wiring the product with power disconnected. Proper supply voltage, polarity and wiring
connections are important to a successful installation. Not observing these recommendations may damage the
product and void the warranty.
TERMINAL
DESCRIPTION
GND ........................... Power Supply Ground (Common to the controller)
V+ .............................. Power Supply Hot (See specs for voltage details)
W1 ............................. Not Used
OCCUPY ................... BAPI-Man Occ/Un-Occ indicator Input.
Ground terminal to fill in the BAPI-Man icon for
Occupied.
SEN1 & SEN2 ........... Sensor output per order (resistive). No polarity.
*If the unit is a common ground configuration, see
“Grounding Note” below.
SET1 & SET2
A) Setpoint output per order (resistive). *If the
unit is a common ground configuration, see
“Grounding Note” below.
B) Setpoint output per order (voltage). SET1 is
“+”, SET2 is “-”.
OVR1 & OVR2........... Override Output (Dry contact) if unit is ordered
with Override as a Separate Output (-J). The
override can also be ordered as a momentary
shunt across the sensor terminals SEN1 & SEN2
(-N) or as a momentary shunt across the setpoint
terminals SET1 & SET2 (-P). *If the unit is a
common ground configuration, see “Grounding
Note” below.
EXT-TEMP & EXT-GND .. Remote sensor terminals. No polarity. *If the
unit is a common ground configuration, see
“Grounding Note” below. To use these terminals,
a 10K-2 thermistor sensor must be ordered
separately and the temperature value from this
sensor will be displayed on the LCD but will not
be sent to the controller. Max wire distance for the
external sensor is 25 feet.
*Grounding Note:
Common Ground or Differential Ground configurations are selected per order (Common Ground is default). The
Differential Ground configuration indicates that SEN2, SET2, OVR2 and EXT-GND must all be wired separately (No
internal common connection). The Common Ground configuration indicates that SEN2, SET2, OVR2 and EXT-GND are
connected to GND internally (All internally common).
