Set-Up Menu – Secondary Alarms - Merlin SmartGauge Installation And User Manual

Merlin Power Systems version: 2.0.2
SmartGauge Installation and User Guide
Primary Alarms – General
Once an alarm is triggered, the alarm output will activate. The Alarm LED on the front panel will
illuminate and the display will alternate between its current display (for 3 seconds) and the alarm
display (for 1 second). The alarm display will show :
"A LU" - for Alarm Low Voltage
"A HU" - for Alarm High Voltage
"A LS" - for Alarm Low Status
If "PA t" has been set, then when the alarm triggers, the display will alternate in 2 ways. It will show
the current display (3 seconds), then it will show "A Lt" (Alarm Low status timed),(1 second), it will
then revert to the normal display (3 seconds), it will then show the time in hours and minutes until
the alarm is due to deactivate (for 1 second). For example for a time of 9 hours 45 minutes, the
display would show "t9.45".
Changing the alarm type will cancel any currently active alarms. Alarm set points and timers can be
changed, and the existing alarm will remain active. But actually changing the alarm type (such as
from low voltage to low status) will cancel the currently active alarm. This is a simple way of
cancelling an active alarm. If the display is in sleep mode then the alarm output will still activate but
the alarm status display will not show, however the Alarm LED on the front panel will still light up.
Pressing either button will show what type of alarm has activated in case you forget which type you
set. And in the case of "PA t" will show the time remaining before deactivation.
5.5 Set-Up Menu – Secondary Alarms
The purpose of the secondary alarm is to activate an external alarm output, perhaps to sound an
audible warning device or warning light in the event of SmartGauge generating one of its several
error codes.
The display will show "SA x", "SA" signifying Secondary Alarm and "x" showing the current setting.
The default is "O", Off. "x" can be set to any of the following:-
O Off Default - Error codes will never activate the alarm output.
U Uoltage - Error codes E 02 and E 03 (low or high voltage warnings for selected battery type) will
activate the alarm output.
r range - Error code E 04 (measurement range error) will activate the alarm output.
P Power lost - Error code E 01 (Power lost) will activate the alarm output.
A All – All Error codes will activate the alarm output.
S SmartBank This option only appears in the set-up menu if a SmartBank is installed in conjunction
with SmartGauge. This option allows the Secondary Alarm to be triggered by SmartBank errors.
Secondary Alarms and Primary Alarms operate independently of each other. They may both be set at
the same time. Adjusting or defeating one will not affect the other. But note that there is only one
hardware output.
