Thermal Alarm Θ
Just like
Trip Θ
,
Alarm Θ
is a heating threshold in
percentage; however,
Alarm Θ
function activates LEDs
and any possibly configured outputs to inform the
administrator to take appropriate precautions, instead
of tripping the circuit breaker.
Alarm Θ
setting can be
done within the range of %50 - %200, with the
limitation that
Alarm Θ
value cannot be set over the
Trip Θ
set value.
Alarm Θ
function can be set as
Active
or
Passive
via the
Alarm Θ
option.
Alarm Θ
function can be utilized in two ways.
When
Thermal Θ
measurement reaches
Alarm Θ
threshold, the user is notified via the static alarm LED
on the frontal face of CPM 310 G, while the alarming
situation is declared on the
Alarm Menu
. The use of
Alarm Menus
will be examined thoroughly on the
dedicated section in the following pages.
Alarm Θ function can also be utilized to automate
cooling systems or to inform the supervisor about the
situation remotely. If, e.g., a forced air cooling system
is to be driven when the protected power transformer
reaches a fixed heating percentage, a programmable
output with Alarm Θ function appointed can be
employed to generate a start signal to the
preconfigured appropriate circuit. If the Alarm Θ
notification is to be sent to the supervisor via an
auxiliary system, e.g. a GPRS communication system, a
programmable output with Alarm Θ function appointed
can be employed to provide notification signal to the
related device. Doing this, CPM 310 G will inform the
configured communications device to take appropriate
action when Alarm Θ threshold is reached. □
