Battery Flashing Configuration
This configuration uses an external battery source to build the terminal voltage to a
point that the automatic voltage regulator can take over and perform its function. This
configuration should be used on brush-type generators as well as installations that
require a guaranteed voltage buildup such as hospitals and correctional facilities.
Take special care to follow the wiring directions precisely! DO NOT use the
battery flash configuration in conjunction with the automatic flash configuration!
Note that the maximum input voltage to the AFM500X Automatic Flashing Module
is 240VAC!
DO NOT input 277VAC into the AFM500X!
Severe damage to the unit
will result! For use on 480V systems, either connect the regulator to the winding center
taps T7 and T8 or use a 480-240V step-down transformer.
NOTE:
Wiring from the AFM500X must ALWAYS be connected to the voltage
regulator terminal board regardless of any other optional modules in use!
†
Refer to your instructions that came with your Universal Voltage Regulator for the interconnect
diagrams to connect your voltage regulator to your generator.
*
Battery Negative must be connected to the generator Neutral or T0 and NOT to F- of the exciter!
