Vector V1100 With A 4-20 Ma Field Device With Battery Powered Operation - GE Masoneilan VECTOR V1100 Instruction Manual

Figure 9 is a simplified schematic representation of this DIRECT POWER multi-drop
configuration with FIELD DEVICE CONTROL is set to the ON position. The LOOP POWER, red
lead wire, is not required for this configuration and is not shown. The EARTH Grounding
connection is not shown.

VECTOR V1100 with a 4-20 mA Field Device with Battery Powered Operation

In this installation option, the VECTOR V1100 is connected in series with an either an analog
only or HART enabled field device and can be configured for either Loop Power or DIRECT
POWER.
An external battery or other DC power source such as solar is used to power the VECTOR
V1100 and field device.
Configured for:
Loop power, the VECTOR V1100 and field device are continuously powered, which is
not the optimum energy management configuration for battery operation.
DIRECT Power, the VECTOR V1100 can control the power to the field device, which
results in optimum energy management for battery operation.
To manage the battery power the VECTOR V1100 must be configured to use the FIELD
DEVICE POWER CONTROL feature which allows you to specify the battery powered on and
off time. This software controlled function is enabled by means of the HART Device
Description (DD). You configure the FIELD DEVICE POWER on time as required by the
application and or as required by the field device to operate properly.
The VECTOR V1100 has internal circuitry to monitor battery consumption when an external
battery is used for the Direct Power input. Since the battery is external, there are many
possible battery options that you could employ; therefore, the VECTOR V1100 battery
measurement circuitry is very flexible and configurable.
There are two major variables measured to determine the remaining battery life - the
battery voltage and the battery coulomb discharge rate. Both of these measurements are
continuously being performed by the VECTOR V1100 on the battery, and both of these
measurements are used to determine the remaining battery life and the power status.
