commands sent to the modem (i.e. initialization, phone number) are defined by
signals in the Dial list.
The use of the modem dial out function implies that the called device has been set
up to 'know' that it should poll for alarms after it answers the call and then hang-
up.
Dialing logic will dial the first phone number three times and then dial a second
number three times, the combination constituting one 'dial-attempt'. To conserve
power the maximum number of attempts per hour is two; this value can be
configured up to 9 by the user.
Battery Charge Control
Signals are provided to allow charge regulator setup and control for either a 6 or 12
volt battery. Should the charge regulator detect battery overcharge, an alarm
occurs, and a shunt regulator is activated which deactivates the solar panel,
thereby preventing an overcharge condition.
Power and Load Status Alarms
The main voltage value will be held in an alarm signal with default limits (in Volts)
as follows:
Low 5.75
High 16.0
Lo-lo 5.5
Hi-hi 16.5
LDb .5
HDb .5
A number of 'load status' logical alarms are provided as follows:
Backflow alarm backflow is detected
Low DP (cutoff ) Dp below cutoff
Backup battery low RAM backup battery
External battery overcharge excess voltage into the external battery
AGA8 Calculation error final value is approximate
Floating-point math error
System self-check system problem
Sensor conversion conversion error
Sensor checksum compensation has changed
