4.3.2 CAN DATA FAIL ALARM
Parameter
Description
CAN data fail
alarm
Action:
None :
Should communications from the engine ECU not be present, no action is taken. The
DSE8810 series module ignores shutdown messages from the engine ECU leaving these to
be handled by the engine ECU. The DSE module continues to provide protection on any
parameters measured directly
Shutdown :
The engine is immediately shutdown upon loss of communications from the
engine ECU.
Warning : Should communications from the engine ECU not be present, a warning alarm is
generated. The DSE8810 series module ignores shutdown messages from the engine ECU
leaving these to be handled by the engine ECU. The DSE module continues to provide
protection on any parameters measured directly
Arming :
From safety On :
The communications link monitoring is activated after the termination of the
Safety Delay Timer.
From Starting
: The communications link monitoring is activated once the engine cranking
begins.
4.3.3 AUTO VOLTAGE SENSING
Auto voltage sensing instructs the controller to monitor the generators output during the safety delay timer.
During this time, the controller identifies the nominal voltage, frequency and topology of the alternator output
and selects the most appropriate ‘alternative configuration’ to use.
This is particularly useful where a generator is switched from 50Hz/60Hz or 120V/240V for example.
NOTE: During the safety delay timer, the module factory set status page will display the L-N
voltage, based upon the generator being 3 phase, 4 wire. This can lead to incorrect status display
during the safety timer if Auto Voltage Sensing is enabled and the generator is not 3ph 4w. To prevent
this, the status page can be customised to display other parameters if required. At the end of the
safety timer, the correct voltages will be displayed.

Enable Auto
Voltage Sensing
= The module will operate as normal.
=
Auto voltage sensing
is enabled. During the safety delay timer, the module attempts to
measure the system’s nominal voltage and frequency and determine the topology of the
alternator wiring. At the end of the safety timer, the main and alternative configurations are
analysed to see which one is most appropriate to suit the connected system and the module
continues to operate, using the most appropriate configuration to provide protection.
Over Voltage
During Auto
Sensing Trip
During the Auto sensing there is no over voltage trip protection from the main settings until
after the safety on timer has elapsed. Therefore the overvoltage trip value is taken from this
setting.
