Meter Installation (w/o Intrinsically Safe Barrier)
WARNING!
The instructions on this page are intended as an introduction to
the proper wiring procedure for the Series 900DP Digital Meter. Detailed wiring
instructions and information are included in the 4 page document labeled:
“FILL-
RITE SERIES 900DP METER, INTRINSICALLY SAFE FLOWMETER”
(control
drawing DC000675-000), included in the box with your meter. These instructions
MUST BE READ AND UNDERSTOOD COMPLETELY PRIOR
to installation.
See
“WARNING”
under “Electrical Installation Information” on page 10 and 11
prior to beginning installation.
For meter installations not located in explosive atmospheres,
the intrinsically safe barrier is recommended, but not
required. The barrier simplifies wiring and improves current
sink and voltage quality. The pulser in the meter is designed
to function directly with Fuel Management Systems using a
current sink output with a maximum load of 20mA.
The Series 900DP Digital Meter can be wired directly to an external DC power source that
operates within the meters parameters (7.5 - 28 VDC, .2A). Any external power sources
should be clean DC from a dedicated circuit. The connections are made at the terminals on
back of the meter. Note the three connections; “+” and “-” for external DC power, and “S”
for pulser signal.
WARNING!
DO NOT install the Series 900DP meter in explosive atmospheres
without the Intrinsically Safe Barrier!
Three wire cable coming into the meter should
be limited to only as much as is necessary
to
complete the wiring.
Excess wiring should not
be left inside the meter.
Auxilliary power and pulser connection at meter.
Note three connections: DC+, DC-, and Pulser
Signal.
