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 900CDP 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.
The Series 900CDP 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 900CDP meter in explosive atmospheres
without the Intrinsically Safe Barrier!
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.
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.
