Vanner Electrical System Monitor

The EM-70D Electronic Monitor is a device designed to monitor several critical functions in the electrical system of a vehicle that operateson a 24 volt system. It will also monitor the 12 volt service when using a Vanner VoltMaster Battery Equalizer which supplies 12 volt servicefrom a 24 volt source. Characteristics The EM-70D can function in a variety of ways: The monitor functions as an alternator monitor when the Battery Balance lamp output and +12 volt monitor inputterminals are not in use. The monitor functions as a device to control a field current relay, shutting down the field current if the voltage regulator failsin the full field mode. This function is accomplished by connecting the EM-70D as normal and installing a latching fieldcurrent relay to the Battery High lamp output terminal.
