Rosemount Model 8800C Vortex Flowmeter with FOUNDATION
™
Fieldbus
2-4
Hardware Configuration The hardware jumpers on the Model 8800C Flowmeter enable you to
set the fieldbus simulate enable and transmitter security (see
Figure 2-4). To access the jumpers, remove the electronics housing
cover from the end of the Model 8800C Flowmeter. If your Model 8800C
Flowmeter does not include an LCD indicator, the jumpers are
accessible by removing the cover on the electronics side. If your Model
8800C Flowmeter includes an LCD option, the fieldbus simulate enable
and security jumpers are found on the face of the LCD indicator (see
Figure 2-5).
NOTE
If you will be changing configuration variables frequently, leave the
security lockout jumper in the OFF position to avoid exposing the
flowmeter electronics to the plant environment.
Set jumpers during the commissioning stage to avoid exposing the
electronics to the plant environment.

Fieldbus Simulate Enable and
Transmitter Security Jumpers.
Simulate Enable The simulate enable jumper is used in conjunction with the Analog Input
(AI) function block simulation. The jumper is also used as a lock-out feature
for the AI function block. To enable the simulate enable feature, the jumper
must transition from OFF to ON after power is applied to the transmitter,
preventing the transmitter from being accidentally left in simulator mode.
Transmitter Security After you configure the transmitter, you may want to protect the
configuration data from unwarranted changes. Each transmitter is
equipped with a security jumper that can be positioned ON to prevent
the accidental or deliberate change of configuration data. The jumper is
located on the front side of the electronics module and is labeled
SECURITY (see Figure 2-4).
