Vcs Ii User Interface - Bergey VCSII Owner's Manual

The charge controller user/operator control input interface consists of a single push button on the front
panel of the charge controller. The single push button performs different functions depending on the
controller system state and operating mode and the length of time that the button is pressed.
The user push button functions are defined as follows:
1) No press of the user push button:
a) If the charge controller is powered up and there are no faults, the charge controller will
automatically go to the Charging Mode. The charge controller will charge the batteries, and
then maintain the battery voltage at a specified float voltage.
2) Press and hold the user push button for more than 0.5 seconds and less than 5 seconds:
a) If the charge controller is powered up and in the Charging Mode with no faults, the charge
controller will go to the Manual Idle Mode.
b) If the charge controller is powered up and in the Manual Idle Mode with no faults, the charge
controller will go to the Charging Mode.
c) If the charge controller is powered up and in a Fault State, the charge controller will clear the
faults and go to the Charging Mode.
d) If the charge controller is powered up and in the Equalize Mode with no faults, the charge
controller will exit Equalize Mode and go to the Charging Mode.
3) Press and hold the user push button for more than 5 seconds:
a) If the charge controller is powered up and in the Charging Mode with no faults, the charge
controller will go to the Equalize Mode for a predetermined time period. After Equalization, the
charge controller will go to normal charging mode, and will maintain the battery voltage at a
specified float voltage.
