Merlin Power Systems
5.4 Set-Up Menu – Primary Alarms
On entering this section of the set-up menu, the display will show "PA
x". PA signifying Primary Alarm. "x" displaying either "O" " U" " S". or
"t". "O" means alarms are switched Off.
"U" means Uoltage (Voltage) alarm is enabled
"S" means low Status alarm is enabled.
"t" means a timed low status alarm is enabled.
"U", "S" and "t" type alarms are more fully described under their
respective headings below.
The SELECT button will scroll round them.
The SET button will set the desired alarm. The display will flash
showing the value was written to memory. Changing the alarm type
will cancel any currently active alarms and reset the timed alarm
timers to the user's programmed default value.
On selecting "PA O" the display will flash and then move onto the
next item in the set-up menu.
Set-up mode – Uoltage (Voltage) Alarm:
1. On selecting "PA U" the display will flash to show
the value was written to memory.
The display will then show either "Hi" or "Lo". The
SELECT button will alternate between these two
options. "Hi" sets a high-voltage alarm. "Lo" sets a
low-voltage alarm. Pressing SET will store the value.
2. The display will then show "XX.XX" which is the
lower voltage trip point. Once this is set (using the
SELECT and SET buttons) the display will again show
"XX.XX" which is the upper voltage trip point.
If a low voltage alarm was set, the lower voltage trip point is the voltage below which the actual
battery voltage will have to fall in order to trigger (activate) the alarm output. This is the activation
voltage. The factory default for this value is 11.80 volts. Pressing the SELECT button will scroll this
value up to and including 16.50 volts. It will then cycle to 10.50 volts, then continue to scroll
upwards. When the desired value is displayed, press the SET button to write the value to memory,
the display will flash. The upper voltage trip point is the voltage which the actual battery voltage will
have to rise to in order to deactivate the alarm. This is the deactivation voltage. The factory default
for this is 13.20 volts. Pressing the Select button will scroll this value up to 16.50 volts, it will then
wrap round to whatever value was previously entered for the alarm activation voltage. This means
that no matter what one does, SmartGauge will not allow this value to be set lower than the
activation voltage. Pressing the SET button will write the value to memory.
