Putting into operation
Once the isometer has been connected and the connections have
been checked, the input voltage of the floating system can be
activated. The isometer will perform a self-test (see the
"Automatic self-test" section). Next, the system is on standby and
can, therefore, be used.
OPER A T I ON A L
Self-test
Automatic self-test
The isometer will automatically run through a connection test and
a self-test every time the current source is switched on. "TES" will
be displayed on the display and all LEDs will light up. After 6 to 12
seconds, the isometer will start up and only the ON LED will be lit
if no errors have been detected. This self-test will, moreover, be
performed every 24 hours.
Manual self-test
A test can also be performed manually. Functional and connection
errors/faults will then be checked. Press the "test" button for 2
seconds. If you continue to press this button, all the icons that are
possible will be displayed on the display. If an error is found, all the
LEDs will start to flash and an error code will be displayed on the
display. See the "Information displayed" section. If an error
message is displayed: switch off the current source, resolve the
error and again switch on the inverter/generator. The self-test
will again be performed.
Insulation resistance
The total insulation resistance of the system will be displayed on
the display. The display will show > 1.0 M
Ω
as standard. When
the consumers are activated, the actual insulation resistance can
be read. The deactivation of the isometer is adjusted to 10 k
Ω
as
standard.
Reset after deactivation
If the set value is exceeded, the isometer will disable the current
source. If this should happen:
