The status output, also located on field wiring terminal, JP7, is a digital 0-15Vdc output. This
output will go low in the event of a fault or power loss. If a non-standard option has been
ordered there will be additional notes in the SECTION 6.3 — SPECIAL INSTRUCTIONS.


The reset input terminals are provided for remote reset of the totalizer. To reset the totalizer
these two terminals need to be shorted together. The ‘+’ terminal is connected to an internal
+5Vdc supply ‘+’ and the ‘-’ terminal is connected to an internal input device and to output
ground through a 47kS resistor. If an open collector (NPN) is used to make this connection,
wire the collector to the ‘+’ terminal and the ‘-’ to the emitter. Reverse the polarity if a PNP
type open collector transistor is used. Connections to this input must be isolated. A
grounded (connected to instrument output ground) emitter of the open collector may destroy
the open collector transistor.


Choose a path for the transducer to transmitter cable conduit. Route the transducer interface
cable conduit. Do not cut or splice the cable, as this may affect the instrument calibration.
Pull the cable through the conduit starting at either end; coil up the remaining length outside
the transmitter or transducer enclosure, or in a cable junction box.


Pull wires through the conduit. Wire for power connection must be at least 24 gauge or as
required by applicable local or company wiring codes. After pulling the wire, pot the conduit
or wires near the enclosure if there is any possibility of water from condensation or spray
entering the enclosure through the conduit.

!! WARNING: The transmitter unit is not protected against condensed
liquid water inside the enclosure. Be sure conduit interfaces are dry or
sealed at the instrument to prevent condensation that may be present in
conduit lines from entering the enclosure.


Make wiring connections. Power should be off at this time. Refer to Figure 3 for system
wiring detail.

!! !! WARNING: Verify the wiring. The equipment can be permanently
damaged if not wired as instructed in this manual.

10. Close the lid of the enclosure. Make sure it is tight enough to make a good seal against

the gasket and ensure all other enclosure openings are completely watertight.
