Sequence control
When the equipment sequence control switches to the "Night" sta-
tus ( Chapter 5.1.6), active earthing is switched off. The insula-
tion test starts with a delay after a test time.
The insulation test is terminated when active earthing is switched
on again. The sequence control ignores the time control and
switches to the "Operation" status before the test time has elapsed
( Chapter 5.1.3).
Maintenance mode
Maintenance mode can be triggered by means of local or remote
signalling. Active earthing switches off immediately when "Mainte-
nance mode" is activated. The digital and analogue signals from
the isometer are ignored.
Active earthing is switched on again when the equipment is
switched to "Operation" status. A minimum time period is stipulat-
ed for "Maintenance mode"; i.e. even if the equipment is switched
over to the "Operation" status, maintenance mode is not terminat-
ed until this time has elapsed.
Starting the insulation test manually
The insulation test can be started manually for maintenance work.
Active earthing is switched off when the insulation test is started.
The isolation test starts after a delay time. When the test time has
elapsed, the insulation test ends and active earthing is switched on
again.
The insulation test can only be started manually if an insulation
test is not already running at the time.
5.5.3 Parameters
The parameters are only relevant for operation with thin-film solar
cells.
Test time:
The analogue and digital signals from the isometer are evaluated
during this time.
Delay following shutdown of K21 (earthing of PV cells)
Time that elapses after active earthing is disconnected and before
insulation measurement begins.
Delay for shutdown of K21 in night operation
Time that elapses after switching over to "Night" status and before
earthing is disconnected with contactor K21.
Minimum time for maintenance mode
Minimum time for which active earthing must be switched off in
"Maintenance mode".
