Mounting

Mount the unit to its mounting surface with four #10 screws through the holes in the mount­ing feet. The preferred mounting orientation is with the pressure ports facing down.

Note: BAPI recommends using #10

screws that require 5/32" pilot holes.

Zone Pressure Sensors (ZPS) - BACK MOUNT

Installation and Operation Instructions

18646_Ins_ZPS_BB_BM

Output Termination

4/6/07rev.

Desired Output Wire connections

4 to 20 mA Red (V+); Black (Return{4 to 20 mA Signal}); White (Not used)
0 to 5 V or 0 to 10 V Red (V+); Black (Ground); White (Output Voltage)

4 to 20 mA is “two wire” operation, the ZPS’s red wire connects to a positive direct current voltage of 7 to 45 VDC,
the ZPS’s black wire becomes the return of the 4 to 20 mA signal and the ZPS’s white wire, while unused, must be
insulated from accidental contact with ground or any other potential. For 4 to 20 mA signaling only direct current can
be used to power the ZPS.

0 to 5 V or 0 to 10 V is “three wire” operation, the ZPS’s red wire connects to either 7 to 45 VDC or 7 to 32 VAC (0-5
VDC output) or 13 to 45 VDC or 13 to 32 VAC (0-10 VDC output), the ZPS’s black wire is connected to ground and
the ZPS’s white wire is connected to an analog input of the controller. BAPI insulates the white wire in the factory
before shipping to you, please remove the connector and strip the insulation from the white wire as desired.

To ensure that all wires are properly terminated, twist the stripped ends of each circuit together before inserting into
the splice terminals. Gently tug on the wire after terminating to make sure of a good connection. If the wire comes
out of the termination repeat the splice procedure.
