D-500 MK3 User Manual Firmware V-7.5

When necessary, the controller may be manually reset by holding the STOP button pressed for 30
seconds.
The manual reset will cause the hardware to be configured following new settings.
It is advised to proceed to a manual reset or power off/on cycle after every hardware configuration
modification.
The controller offers the capability of automatically determining the connection topology and setting the
voltage checks in accordance.
Related parameters are:
Automatic Topology
Detection
- 0 1 0
If this parameter is enabled, when the
engine runs, the controller will detect
the connection topology automatically
and will select alarm levels accordingly.
0: auto detect not enabled
1: auto detect enabled
If the automatic topology determination is activated by program parameter, when the engine runs, the
connection topology is tested to be one of below ones
during “holdoff timer” period.
If below voltage conditions are met continuously during 3 seconds, then the topology is considered to be
determined.
If the topology cannot be determined during holdoff timer duration, then an “
Unknown Topology
”
loaddump is generated, and the engine stops after cooldown.
This feature is especially useful for manual voltage adjustment after a new topology selection.
Available topologies to be determined are:
TOPOLOGY Voltage Overcurrent Limit Overload Limit
High Wye 314V > L1&L2&L3 > 182V Overcurrent limit x1 Overload limit x 1
Low Wye 157 V > L1&L2&L3 > 92 V Overcurrent limit x2 Overload limit x 1
High Zigzag 276 V > L1&L2 > 204 V Overcurrent limit x1 Overload limit x 2/3
Low Zigzag 136 V > L1&L2 > 84 V Overcurrent limit x2 Overload limit x 2/3
During topology determination phase, if the RUN button is held
pressed, the holdoff timer will not expire and the controller will
try to determine the topology as long as the RUN button is held
pressed.
