Problems with LeoPC1 During Read and Write of the Parameters

NOTE
LeoPC1 V3.1.xxx or higher must be installed to read and write the parameters for the
correctly.
With some computers a crash may occur during reading/writing of parameters with LeoPC1. If this happens
change the following settings:
In LeoPC1 (English):
Devices-> Settings-> (Data communication) Settings-> Options ->
Timeout after writing a command, change to 100, this could also be another value (except 0), depending on
the computer´s capacity
LeoPC1 (Deutsch):
Geräte-> Einstellungen-> (Datenkommunikation) Einstellungen-> Optionen->
Timeout nach dem Schreiben eines Befehls auf 100 setzen.
Der Wert kann je nach PC-Leistung auch geringer oder höher eingestellt werden.
Depending on the parameter voltage transformer secondary the corresponding terminals have to be connected
like this (each for generator and mains):
From 50 to 120V:
From 121 to 480V:
Otherwise the reading of the voltage is incorrect.
For PTs with 120V: If your voltage transformers are not very accurate and you like to adjust the PT ratio to cor-
rect the displayed value change only the primary voltage.

It is possible to use only the start/stop sequence of this unit e.g. for a single motor. The engines' voltage and cur-
rent will not be connected to the easYgen. In this case the unit will monitor the speed via pickup and engine sig-
nals like discrete and analog inputs. It can not operate a circuit breaker. It will still display the screens for the
generator voltage and current but the ones for the mains can be switched off. The turning arrow in the generator
symbol in the base screen displays a running engine. It is also possible to display the ECU data via CAN bus if
connected. As there is no "GCB open" signal it might be necessary to configure a relay which energizes when a
stopping alarm (parameter 1.09) occurs to open a breaker.
In this application you will only use the monitoring of start/stop, pickup, 2 analog inputs and 8 discrete inputs.
