5.3 STOP MODE
STOP mode is activated by pressing the
button.
In STOP mode, the module will immediately remove the generator from load (if necessary) before stopping the
engine if it is already running. No cooling run is provided for this operation. Where a cooling run is required, switch
to MANUAL mode and open the breaker manually. Allow the set to cool off load, before pressing the STOP button
to stop the engine.
If the engine does not stop when requested, the FAIL TO STOP alarm is activated (subject to the setting of the Fail
to Stop timer). To detect the engine at rest the following must occur:
•
Engine speed is zero as detected by the Magnetic Pickup or CANbus ECU (depending upon module
variant).
•
Generator frequency must be zero.
•
Oil pressure switch must be closed to indicate low oil pressure (MPU version only)
When the engine has stopped, it is possible to send configuration files to the module from DSE Configuration Suite
PC software and to enter the Front Panel Editor to change parameters.
Any latched alarms that have been cleared will be reset when STOP mode is entered.
The engine will not be started when in STOP mode. If remote start signals are given, the input is ignored until AUTO
mode is entered.
When configured to do so, when left in STOP mode for five minutes with no presses of the fascia buttons, the
module enters low power mode. To ‘wake’ the module, press the
button or any other fascia control button.
5.3.1 ECU OVERRIDE
Not applicable to DSE8716 display
NOTE:- Depending upon system design, the ECU may be powered or unpowered when the module is
in STOP mode. ECU override is only applicable if the ECU is unpowered when in STOP mode.
When the ECU is powered down (as is normal when in STOP mode), it is not possible to read the diagnostic trouble
codes or instrumentation. Additionally, it is not possible to use the engine manufacturers’ configuration tools.
As the ECU is usually unpowered when the engine is not running, it must be turned on manually as follows:
•
Select STOP
mode on the DSE controller.
•
Press and hold the START
button to power the ECU. As the controller is in STOP mode, the engine will
not be started.
•
Continue to hold the start button for as long as you need the ECU to be powered.
•
The ECU will remain powered until a few seconds after the START button is released.
This is also useful if the engine manufacturer’s tools need to be connected to the engine, for instance to configure
the engine as the ECU needs to be powered up to perform this operation.
