6. ELECTRIC CONNECTION
6.1 Install Conduit
Transmitter junction boxes have n.4 M16*1.5 conduit connections.
Seal unused ports to prevent moisture or other contamination from entering the junction box.
Do not overtighten metal plugs used to seal wiring compartment ports,overtightening can damage the housing.
6.2 Power Connections
To connect power to the transmitter, complete the following steps:
1) Open the power terminal cover.
2) Run the power cable through the conduit to the transmitter.
3) Loosen the terminal cable guard for the input power terminals L and N or + and -.
4) Connect the power cable leads as follows:
For an AC-powered transmitter (fig.2-13):
- Connect AC Ground to a grounding lug.
- Connect AC Neutral to terminal N.
- Connect AC Line to terminal L.
For a DC-powered transmitter (fig.2-13):
- Connect DC Ground to a grounding lug.
- C DC.
- Connect - DC.
6.3 OUTPUT
Satisfy these requirements before attempting to install and operate the Pmag.
6.3.1 Analog output
The loop may be powered from the transmitter itself. Resistance in the loop must be 750ohms or less.
6.3.2 Digital output
The digital output, if set frequency mode generates an output signal from 0 to 5000Hz Max. proportional to flow rate,
if set in pulse mode generates an output signal in relation to totaled volume increasing. The signal is normally used in
conjunction with an external totalizer or control system. complete the following steps to connect the signal cable to
the transmitter:
1) Run the signal cable into the transmitter.
2) Connect the two wires that convey switch closure information to the F+ and F- terminals
6.3.3 RS485 serial output
In models with RS485 option can communicate via Modbus . Connect the serial cable to terminals A + and B-
