INTRODUCTION:

The 720-MDVSO (VSS –Voltage Sensitive Switch) automatically senses voltage and provides optimal,

ef cient charging of a second independent battery bank. The VSS allows the battery banks to be combined

or isolated based on the presence of a charging source (such as an engine alternator or battery charger),

while also offering remotely activated, high current, emergency parallel connection of the banks.

Designed and constructed for longevity in the marine environment with tinned copper conductors, stainless

steel nuts and high temperature,  ber reinforced plastics. The units are ignition protected, provide On/Off

switching operation, and may be recessed or surface mounted.

The 720-MDVSO features digital circuitry and optical sensor positioning that automatically senses 12V or

24V input, is extremely accurate, and offers low power consumption.

Motorised Battery Switch Model: 720-MDVSO 12/24V Voltage Sensitive Switch OPERATION AND INSTALLATION INSTRUCTIONS 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 flat start battery.

Motorised Battery Switch Model: 720-MDVSO 12/24V Voltage Sensitive Switch OPERATION AND INSTALLATION INSTRUCTIONS GENERAL OPERATION: Note that the knob must be firmly 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.

Motorised Battery Switch Model: 720-MDVSO 12/24V Voltage Sensitive Switch OPERATION AND INSTALLATION INSTRUCTIONS INSTALLATION: Battery cables must be correctly selected for the maximum loads expected. Cables must be a minimum of 1x 95mm² (3/0) to achieve 350 amps continuous. Cables must be a minimum of 2x 95mm² (2x 3/0) to achieve 500 amps continuous. Ensure nuts on studs are correctly tightened. Recommended torque is 18 Nm (13.3 lbf). Maximum torque 25 Nm (18.5 lbf).
