IntelliLINK
AC Power
This field shows whether the switch control is presently running on ac power, sensor
power if applicable, or battery power.
Cabinet Temperature (Deg. F)
This is the present temperature inside the switch control enclosure, measured by the
thermistor on the front of the Power Supply/Control I/O module. The switch control uses
this value to make certain corrections to the calendar clock and ac waveform condition-
ing electronics.
Battery System State
This field shows if the battery presently contains enough charge to operate the switch.
Three states are possible:
Normal
Enough charge is present to operate the switch.
Low
The battery is in a marginal condition; it will soon be depleted and unable
to operate the switch. (No damage should occur to the switch if you try
to
operate
it.)
Bad
The battery charge is too low to operate the switch.
Battery Charger Failure
This field indicates the type of charger malfunction. The field is set or cleared during a
battery test. Three states are possible:
N/A
Not applicable; no alarms are present.
Overvoltage
A high voltage was applied to battery system by the charging system.
The battery charger is shut down on this alarm condition.
Low Impedance
The calculated battery impedance is too low to be valid.
Over Volt/Low Imped
Both overvoltage and low impedance conditions are present.
Power Supply Voltage
This field shows the actual voltage presently being supplied to the 24-volt or 36-volt power
system. If ac power, or sensor power if applicable, is present, this voltage is supplied from
the Power Supply/Control I/O module. If ac power, or sensor power, if applicable, is absent,
this is the actual battery voltage. During battery testing this voltage varies as the switch
control applies test loads to the battery system.
Battery Voltage w/o Surface Charge
This is the battery voltage under normal operating loads. If ac power is present, this value
is only updated during battery testing. If ac power and sensor power are absent, this is the
real-time measurement of battery voltage.
