Alarm Output:
For meter models with alarm output installed it is possible to set alarms. There are two alarms that
can be programmed to activate once the programmed set-points are surpassed. The alarms are active
when the LEDs on the top corners of the display are illuminated. With this alarm option the user must
enter the setpoint at which the alarm will be activated, the type of alarm it will be, as well as the
characteristics of the alarm. The alarms can also be hooked up as an output in order to activate
external devices. The setup for this function is below.
Setup:
The alarm output setup is shown to
the right. An example of an alarm
indicator is a noise alarm that will
sound once the alarm is activated
and the normally open relay is
closed. If you are using alarm 1 it is
only necessary to hook up alarm 1.
There is no internal power source for
the alarm relay so it is necessary to
connect a power source in the
connection. First, decide if you would
like to use a normally open (N/O)
switch or a normally closed (N/C)
switch. Once you have made your
decision use the corresponding pin,
connect one wire to the N/O or the
N/C switch and the alarm indicator
(sound alarm). Connect the other
wire from your alarm indicator to the
external power source. Finally
connect a wire from the alarm
ground (Common) to the power
source. You are now ready to
configure the alarm.
