6.1
Hardware switches
The electronics are equipped with four user-selectable hardware switches. These switches
set the Alarm Mode, Internal/External Analog Power, Transmitter Security, and Internal/
External Pulse Power.
Definitions of these switches and their functions are provided below. To change the
settings, see below.
6.1.1
Alarm mode
If an event occurs that would trigger an alarm in the electronics, the analog output will be
driven high or low, depending on the switch position. The switch is set in the HIGH position
when shipped from the factory. Refer to
the alarm.
6.1.2
Transmitter security
The SECURITY switch allows the user to lock out any configuration changes attempted on
the transmitter.
•
When the security switch is in the ON position, the configuration can be viewed but
no changes can be made.
•
When the security switch is in the OFF position, the configuration can be viewed and
changes can be made.
The switch is in the OFF position when the transmitter is shipped from the factory.
Note
The flow rate indication and totalizer functions remain active when the SECURITY switch is in either
position.
6.1.3
Internal/external analog power
The 4–20 mA loop can be powered internally by the transmitter or externally by an
external power supply. The ANALOG switch determines the source of the 4–20 mA loop
power.
