Input Power
CAUTION: If 24 VDC is used as a power source, the terminals are not power isolated.
The flow transmitter is powered by 115 VAC, 230 VAC or 24 VDC (only one power source is needed).
If 115 VAC is used, wire it directly to JP1 and position switch S1 to be in the 115 V position. See
Figure 8 for details. If 230 VAC is used, position switch S1 to be in the 230 V position and then wire
the power directly to JP1. See Figure 8 for details. If 24 VDC is used, it is wired directly to JP1 as
shown in Figure 8.
The installation of an AC line disconnect switch (and possibly a fuse) between the power source and
the flowmeter is strongly recommended. This facilitates easy power disconnection during calibration
and maintenance procedures as well as an added safety feature.
Remote Transmitter
Feed the flow element cable and the two voltage/current output cables through the left access port in the
remote enclosure. Similarly, feed the AC power line and the two relay cables through the right port.
This separates the I/O signal and low voltage DC lines from the high voltage AC and relay lines. See
wiring diagram, Figure 8 for the flow element wiring to JP3. Customer connections needing to be made
are to JP4 and JP5 (relay logic), and also to JP6 (current or voltage).
