The Load Manager Mark IV is a 10-channel sequencer and load-shedding controller operating 10 vehicle installed relays. Upon closing a Master Switch to initiate the sequencing, the 10 outputs are energized sequentially at approximately 1/2 second intervals and upon shutdown they are de-energized similarly.
In addition the Load Manager Mark IV monitors the vehicle’s battery voltage. When electrical loads exceed alternator output, the voltage drops. The Load Manager Mark IV senses this and the outputs are individually de-energized.
A programming switch permits the installer to limit the sequencing to 5, 6, 7, 8, 9 or all 10 outputs. Sequencing operation is completely independent of the load shedding control. The 10 outputs are shed individually when the system voltage sensed is low. The priority is completely random so that any output can be programmed to be the first to be shed. Any other output can be second and so forth. If some critical loads, which the installer determines must never be shed, are connected to the Load Manager Mark IV, the programming switch may be set to never shed those loads.
An indicator is included to signal when the Load Manager Mark IV is active and when it is in the Load Reduce mode.
Note: Load Manager Mark IV operates external relays, which are provided by the installer. Connecting them to ground energizes the relays. The minimum coil resistance is 40 ohms.
