o
P.420: is the length (in minutes) of the test (if zero the test will never be
performed).
It is identical to the manual command but the command is given from the serial port (from a
PC or other devices). To end the test it is necessary to give the opposite command to the
device (pressing the “STOP” key will cause the activation of a block). If the serial connection
breaks off while running the test, the device comes back to its normal automatic working mode.
The operator can start a test by sending a SMS containing a specific text (see SICES
document EAAS0180xx). In the same way the test can be ended. NOTE: the test can be
started in this way only if the parameter P.429 (test length) has a value different from zero:
this because there is no certainty to receive the SMS which ends the test, and so it is
necessary to use this parameter as maximum test length over which the test is anyway
interrupted.
DST2600 has many protections, for the safeguard of both the engine and the generator. Some
of them are defined as limit value of their related measurements, some other as percentage
with respect to a minimal value.
Following the system implementation or the type of intervention that they have, the modality
to disable the protections changes: it can be necessary to set a particular value in a threshold
value or simply to deselect the protection itself.
In the document EAAM0147xx (parameter
list) there is a complete list of the parameters and of the value to insert in them to
disable each single protection (“values for disabling the protections”). It may be
necessary to have the password to accede to the parameters programming.
DST2600 has five working modes, selectable with the cursors keys (see par. 8.3.1) and with
the “START” and “STOP” keys:
“OFF_RESET”: the genset is stopped (or in the stopping phase), all the anomalies are
reset and it is possible to enter in the programming procedure to changes the
parameters.
“MAN”: the engine start and the loads changeover are managed by the operator (the
device won’t never do automatically these operations). Normally the operator has do
the engine stop and the loads changeover on mains; since protections are enabled,
the devices can anyway changeover the loads on mains if the generator is non in its
