3.8 Alarm, buzzer and relay:
On most of the BMV’s readings an alarm can be triggered when the value
reaches a set threshold. When the alarm becomes active the buzzer
starts to beep, the backlight flashes and the alarm icon is visible in the
display along with the current value.
The corresponding segment will also flash. AUX when a starter alarm
occurs. MAIN,MID or TEMP for the corresponding alarm.
(When in the setup menu and an alarm occurs, the value causing the
alarm will not be visible.)
An alarm is acknowledged when a button is pressed. However, the alarm
icon is displayed as long as the alarm condition remains.
It is also possible to trigger the relay when an alarm condition occurs.
BMV 700 and 702
The relay contact is open when the coil is de-energized (NO contact),
and will close when the relay is energized.
Factory default setting: the relay is controlled by the state-of-charge of the
battery bank. The relay will be energized when the state-of-charge
decreases to less than 50% (the ‘discharge floor’), and will be de-
energized when the battery has been recharged to 90% state-of-charge.
See section 4.2.2.
The relay function can be inverted: de-energized becomes energized and
vice versa. See section 4.2.2.
When the relay is energized, the current drawn by the BMV will increase
slightly: see technical data.
