DST2600 User’s Manual 21
If while the test is running there is a mains failure and there are the proper conditions on
generator frequency and voltages, the device does the changeover of the loads and comes
back to its normal AUTO working mode.
While the test is running, with the proper generator condition on frequency and voltages,
pressing the
“KM/KG” key the loads are changed over from mains to generator and vice-versa.
Pressing the “START” key with DST2660 in “AUTO” mode the device begins the automatic
cranks sequence. Press the “STOP” key to end the test, coming back to the normal automatic
working mode.
It is identical to the manual command but the command is given activating one digital input,
previously configured for this function. In this case, to end the test it is necessary to deactivate
the input
(pressing the “STOP” key will cause the activation of a block).
To enable the periodical test it is necessary to set the some parameters. The procedure is
changed from revision 00.06 of DST2600.
Up to 00.05 version:
parameters involved are P.419 and P.420. Parameter P.419 is
a time expressed in hours: it is the time interval between one test and the next. This
time is computed from the beginning of the previous test (the length of the test has
not influence over its repetition time). The parameter P.420 is a time expressed in
minutes and it is the length of the test.
From 00.06 version:
parameters involved are P.418, P.419 and P.420.
o
P.418: by this parameter you can select one ore many days of the week. In
these days, the periodical test will be performed. If you set the parameter to
zero, no periodical test will be done. Each day is associated with a numerical
value: you must set P.418 with the sum of the values related to the desired
days.

For example, if you set P.418
as “42”, the periodical test will be carried out on
Monday, on Wednesday and on Friday (because 42 is the sum of 2, 8 and
32).
o
P.419: by this parameter you can select the starting time for test (from 00:00
to 23:59).
