GENERAL OPERATION:
Note that the knob must be rmly depressed prior to manual rotation, in order
to disengage the motor drive. Failure to do this could damage the motor drive.
The VSS Battery Switch, (720-MDVSO) has two modes of operation, Auto and
Manual. There is an LED located on both the battery switch and the optional
remote key switch, indicating battery switch status.
AUTO OPERATION:
The switch moves between the “Auto Off” and “Auto On” positions depending
on the battery voltages, on either battery bank.
Switches “Auto On”: Volts >13.3V (26.6V)
Switches “Auto Off”: Volts <12.7V (25.4V)
following a 20 second delay
Over-Voltage:
If voltage reaches 16.0V (or 30.5V on a 24V system), the VSS will immediately
switch to “Auto Off”, and the LED status light will ash rapidly. Normal Auto
Operation will only resume when voltage has returned below the over-voltage
limit.
Auto operation of the Battery Switch is not possible whilst in manual mode.
Knob must be returned to “Auto Off” or “Auto On” before normal automatic
operation can continue.
Auto Mode LED Indications:
LED Off: Battery switch is Off
LED On: Battery switch is On
Rapid LED Flash: Over/under voltage condition
MANUAL OPERATION:
The automatic operation of the 720-MDO battery switch can be overridden at
anytime by depressing the control knob and turning clockwise towards the
“Man On” position, or counter clockwise towards the “Man Off” position.
During the time that the Battery switch is in “Man On” mode, the LED is
Illuminated. And the “Man On” symbol is visible (See above).
