1. 12/24 Volt Select Switch
On the back of the VA-1A is a select switch to set the "High Volts" and "Discharge" warning
features for a 12 or 24 volt system (see Installation Instructions).
2. "High Volts" Warning Light
If the bus voltage rises to 15.3 volts (30.6 volts for a 24-volt system) or higher, a bright red "High
Volts" warning light will alert you of this condition. The high volts feature is sensed off the red
power lead and will function regardless of installation variations or what position the mode switch
is in. If this light is on, an External Warning Line will be pulled low which can be used to activate
an External Warning Light.
3. "Discharge" Warning Light
If the bus voltage drops below 12.6 volts, (25.2 volts for a 24-volt system) a bright yellow "Dis-
charge" warning light will alert you of this condition. The discharge warning feature is sensed off
the red power lead and will function regardless of installation variations or what position the mode
switch is in. If this light is on, an External Warning Line will be pulled low which can be used to
activate an External Warning Light.
