Chapter 4: Operation
This chapter covers the following topics:
Powering Up/Powering Down the Device
Establishing Communications
Communicating using the HMI Module
This section describes day-to-day operation of the flow computer including how to turn it
on and off and how to communicate with it.
4.1 Powering Up/Powering Down the Device
Do not attempt to connect or disconnect power from the unit in a hazardous area.
Ensure the area is non-hazardous. Failure to do so could result in an explosion.
1.
Open the enclosure door.
2.
Terminal block TB2 (pins 1,3,5,7) includes connections for DC power (DCIN+, DCIN-)
and battery/ solar power (BATT+, BATT-). The internal battery (which is also used
with solar power) has its own internal connectors.
Plug in TB2 (pins 1,3,5,7) to activate DC or battery/solar power. If your device
uses an internal battery and it is not connected, connect it as discussed in
2.8.3 Connecting Battery Power.
Unplug TB2 (pins 1,3,5,7) to deactivate DC or battery/solar power.
This turns on (or shuts OFF) power from either an external power supply or the
battery pack/solar panel.
Note
When you turn power on, the backlight on the HMI module lights, momentarily turns off
and then remains lit while the INPUT LED blinks. After approximately one minute the
initialization process finishes and the HMI starts to display live data.
4.2 Establishing Communications
The flow computer supports three ways to establish communications: through the host
SCADA system, through a local laptop computer running FBxConnect, or through the HMI
module.
