Figure 2.2 – Terminal Block Description
J1 – Power In
The MTSE can be powered with 24VAC or 24VDC. Allowable range is
20-28V. Pin 1 on the power supply terminal is the positive leg, however the
device is reverse polarity protected.
J2 – Future Sensor
Module Expansion
Additional remote MTSE units will be daisy-chained together to expand the
sensing capability to 40 sensing points. Currently not available.
J3 - Service
Communication
Communication pins for Factory programming. DO NOT CONNECT TO
THESE PINS.
J4 - Network
Communication
BACnet/Modbus communication pins.
J5 - Digital Inputs
and Digital Outputs
Not Used
J6 - Future Sensor
Module Expansion
Will provide power for additional MTSE sensor module units. Currently
not available.
J7 - 24VDC Output to
Temp. Transmitters
Supplies power for external temperature transmitter(s).
J8 - Analog Inputs
Analog Inputs are tied to the temperature inputs and are scaled to the
minimum and maximum values set in
Temperature Compensation &
Altitude
Setup Menus.
J9 - Analog Outputs
System 1 Analog Process Output is System 1 Total Summed Flow (Process
Value) of the sensors in System 1. This is scaled to the Operating Range set
in the Setup Menus where 0V or 4 mA is 0 flow and 10V or 20 mA is the
operating range.
