LP-1/2/3 Power Supply Data
Register Description Comments Read/Write
#AI1.7 Ambient temperature 0-32760 = -23 to 77 °C* (LP-1)
0-32760 = -60 to 100 °C* (LP-2/3)

#AI1.8 DC INPUT supply voltage to LP-1/2/3
Mains Fail: If the supply voltage drops
dramatically, it can be assumed that the
LP-1/2/3 is now running off the battery and
mains fail has occurred.
e.g.
If #AI1.8>17690 (13.5V) = Mains OK
If #AI1.8<17035 (13.0V) = Mains Fail
0-32760 = 0 to 25V

#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 Port 4 hardware wakeup (LP-1
only)
Ch 5 Port 1 CTS change
Ch 6 Port 2 CTS change (LP-1 only)
Ch 7-8 Not used
LP-1 default: #AO2.9 = 0.
When #AO2.9 Chs 1-8 are set to 0,
the RTU will use 18 Hex (chs 4 & 5
=1) for the Low Voltage Wakeup
Conditions.
LP-2/3 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 (LP-2/3)
or monitor supply voltage every 5 minutes
(LP-1)
1 to 254 = check supply volts every 1 to
254 minutes respectively
255 = disable low voltage shutdown (LP-1)
Default = 0
LP-2/3: 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-1/2/3 to monitor the
supply voltage (please see
#DO2.12 below)
Read/Write
#AO2.10 Input Supply Shutdown/Startup voltages
Chs 1-8 (1-255 x 0.1 V) = LP-1/2/3
shutdown voltage
Chs 9-16 (1-255 x 0.1 V) = LP-1/2/3
startup voltage
Default: AO2.10=7668 Hex
Chs 1-8 = 104 (68H) = 10.4V
shutdown
Chs 9-16 = 118 (76H) = 11.8V
startup

* The LP-1 can only measure temperatures 0 °C and above. The negative temperature limit allows for future
development.
