NOTE
The value shown in Wireless HART Packets per second column is
the value reported back in HART Command 777.
Loop Powered This allows for different StepVolt settings to be selected when
operating in a loop powered mode.
Direct Powered – Max
Bandwidth This allows for the maximum wireless HART bandwidth possible
and assumes that the direct power source can supply maximum
power.
Direct Powered – Power
Save This assumes that the direct power source is limited and limits the
amount of wireless HART packets to a small amount to conserve
power.
Direct Powered - External
Battery This assumes that the direct power source is an external battery,
and this enables the built-in battery management functionality
(battery life calculations, battery alerts) in the VECTOR V1100.
CAUTION
The VECTOR V1100 powers up and begins to operate with any
valid power installation, regardless of what the configured
Adapter Power setting. This allows you to change this setting
even if it is configured incorrectly, however, perform any
changes to this before the VECTOR V1100 has joined the
wireless HART network. If this power setting is set different than
how the VECTOR V1100 is actually powered (such as a Direct
Powered setting is selected but the unit is actually loop
powered), the system operation is not guaranteed and it is
possible that the VECTOR V1100 resets due to insufficient power
once connected to the wireless HART network.
The unit can be both Direct Powered and wired in series with the
loop. When configured in any of the Direct Powered modes,
there is an insertion voltage drop of 1.0 V if the VECTOR V1100 is
also wired in series with the loop.
Field Device Power Control
When used in a direct power configuration, the VECTOR V1100 can activate a switchable
terminating resistor between the HART and the RETURN signal wires. This can eliminate the
need for an external terminating resistor in some installations and also allows for the field
device power to be switchable and controlled automatically by the VECTOR V1100.
The parameter Field Device Power Control can be set to three different states:
Off The Field Device Power Control switch is never connected.
On The Field Device Power Control switch is always connected.
Switching The VECTOR V1100 automatically controls the operation of the
Field Device Power Control switch.
