high temperature bre reinforced plastics
• Power draw: Off/Auto Off: 5mA @12V, 5.5mA @24V
Auto On/On: 8.3mA @12V, 12.5mA @24V
• Emergency Parallel: Remote switch activates parallel for 10 minute period
Pressing remote switch for 6 seconds, deactivates
parallel function.
Remote emergency parallel VSS control is achieved by using a remotely
mounted momentary switch, such as the BEP #80-724-0007-00 unit (pictured
at right), which also features an LED to show the VSS status. When operated,
the remote switch engages the 720-MDVSO contacts, paralleling the batteries,
for a 10 minute period, for example to get an engine started following a at start
battery.
Alternatively, the VSS can be manually overridden to either “Manual On”,
or “Manual Off” modes.
