AI1.8 DC Supply Voltage to LP-2/3
Mains Fail: When powered using an AC/DC
supply (@13.8 VDC) and a backup battery, If
the supply voltage drops, it can be assumed
that the LP-2/3 is now running off the battery
and mains fail has occurred. ie:
If #AI1.8>21948 (13.5V) = Mains OK
If #AI1.8<21135 (13.0V) = Mains Fail
0-32760 = 0 to 20.15 V,
Accuracy: + 2%
The DC Supply Voltage is
either the supply voltage
connected to +VIN or +B
(whichever is greater)
Note: 5V Out must be enabled
to allow the LP-2/3 to monitor
the supply voltage.

AO2.9
Chs 1-8
Low Voltage Wakeup Conditions. The initial
setting in this register specifies which wakeup
triggers to enable. When the RTU wakes up
(after the supply voltage is restored), the
wakeup trigger that was activated is written to
this register by the RTU.
Ch1 Time wakeup (automatically set)
Ch 2 Digital input 1 Change Of State
Ch 3 Digital input 2 Change Of State
Ch 4 Not used
Ch 5 Port 1 CTS change (default)
Ch 6-8 Not used
Default: #AO2.9 = 10 Hex (Ch
5 = 1)
When #AO2.9 Chs 1-8 are set
to 0, the RTU will use 10 Hex
(Ch 5 = 1) for the Low Voltage
Wakeup Conditions.

AO2.9
Chs 9-16
Low Voltage Monitoring Interval
0 = Do not monitor supply voltage
1 to 255 = Monitor supply voltage every 1 to
255 minutes respectively
Default: 0 = low voltage
shutdown disabled
Set #AO2.9 = 256 or 16#100
(100 Hex) or similar in ladder
logic to enable low voltage
shutdown and monitoring of the
supply every minute.
Note: 5V Out must be enabled
to allow the LP-2/3 to monitor
the supply voltage (please see
#DO2.12)

AO2.10 Input Supply Shutdown/Startup Voltages
Chs 1-8 (1-255 x 0.1 V) = LP-2/3 shutdown
voltage Chs 9-16 (1-255 x 0.1 V) = LP-2/3
startup voltage
Default: AO2.10=7668 Hex
Chs 1-8 = 104 (68H) = 10.4V
shutdown
Chs 9-16 = 118 (76H) = 11.8V

* The LP-2/3 can only measure temperatures 0 °C and above. The negative temperature limit allows for
future development.
