FP4000 Rev0204

OPERATION

On power-up the pressure gauge/flowmeter will be in the normal operating mode.

Pressure and flow rate information from a transducer and a flow sensor or from the

datalink interface is processed and displayed. Operator input is necessary only when

using the totalizing function (with the optional external button) or accessing program

information.

Datalink Interface

The FRC datalink interface is standard on all pressure gauge/flowmeters and

provides a way of connecting multiple display modules on a shared data bus. The

FP4000 (pressure gauge/flowmeter) and DF4000 (digital flowmeter) series display

modules can operate as independent displays or they can be interconnected to provide

remote displays, the display of flow through multiple discharges (summing), and the

display of total flow for multiple discharges (accumulation). (Refer to Figure 7.)

Note: The FP4000 series can only be used as a primary or remote display

module.

Primary Display Module

Primary displays are programmed with the module function Pri. A primary display

receives input from the pressure transducer and flow sensor. When it is programmed

with Id 0 it will not output information on to the datalink. When it is programmed with

Id 1 to Id 99, it will provide information (via the datalink) to remote, summing, and

accumulator displays.

Remote Display Module

Remote displays are programmed with the module function SLA (slaved to a

primary). A remote display must be programmed with the same ID number as a primary

display. It will receive information for the display of pressure and flow rate from the

primary display over the datalink. All program code features are programmed

independently of the primary display. No calibration is necessary on a remote display.

Summing Display Module

Summing displays are programmed with the module function SU. A summing

display will show the actual flow rate for all primary displays on the datalink except

for those with Id 0. (Available on the DF4000 series only.)

Accumulator Display Module

Accumulator displays are programmed with the module function ACC. An

accumulator display will show total accumulated flow for all primary displays on the

datalink except for those with Id 0. The number shown in the display will be x 100

scale. (Available on the DF4000 series only.)
