VA-1A Functions

Voltage Alerts
Not only do the VA-1A and VA-1A-XX provide pilots with precision voltage (to .1 volts) and Amps (to .1 Amps), but it keeps a watchful eye on the electrical system. Both systems have a "Discharge" light for low voltage situations, as well as a "High Voltage" warning light for over-voltage situations.

The systems also come complete with an external warning line that can be attached to a warning device, such as an Electronics International AL-1 Warning Light, AV-17 Voice Annunciator or ATG-1 Tone Generator, or myriad other warning devices.

Discharge Warning Light
For a 12 volt system, the light will be on when bus voltage falls below 12.8 volts (+/- .2 volts). For a 24 volt system, the light will be on when the bus voltage falls below 25.6 volts (+/- .4 volts). The voltage signal is picked up on the red power lead to the instrument.

High Volts Light
For a 12 volt system, the light will be on when the bus voltage exceeds 15.4 volts (+/- .3 volts). For a 24 volt system, the light will be on when the bus voltage exceeds 30.8 volts (+/- .6 volts). The voltage signal is picked up on the red power lead to the instrument.

External Warning Line
Both the VA-1A and VA-1A-XX have an external warning line that activates during a "High Volts" or "Discharge " scenario. The line is normally open, but when activated, it pulls to ground. You can hook the external warning line to any Electronics International warning device, such as an Al-1 warning light, AP-7 Annunciator Panel, ATG-1 Tone Generator or the AV-17 Voice Annunciator.

12/24 Volt Switch
A selector switch is located on the back of each VA instrument, which allows the instrument to be configured for either a 12 volt system or 24 volt system.
