D-700 MK3 User Manual Firmware V-16.8

The unit is able to work as DC genset controller with optional plugin DC module. The genset starting is
based on the precisely measured DC battery bank voltage.
Once started, the controller will perform an optimal battery charging cycle and will stop the genset when
batteries are fully charged.
The optimal charge algorithm allows maximum battery life and minimal engine run time and fuel
consumption.
The unit decides with precision the moment to run the genset and performs a high efficiency charging cycle.
The complete charging cycle will always include a float charge cycle. Following programming, a boost charging
cycle may be added.
The maximum charge duration is limited w
ith parameter “
Max Charge Time
”. Following the value of the
parameter “
Stop Current percent
”, the controller will detect precisely the end-of-charge condition and will
stop the engine before the expiration of the Max Charge Time parameter, providing fuel economy and longer
service life.
Below picture describes the charge cycle steps in detail.
It is strongly recommended to wire speed detection
through MPU, charge alternator pulses or J1939-
CANBUS and enter correct low and high rpm limit
values in order to preserve engine speed protection.
