Inhibit mode is
activated
The Inhibit mode makes it possible to set the emergency mode to "inhibited"; in this
mode, the power can be turned off without switching to emergency mode.
The Inhibit mode is activated by sending the inhibit signal, while the modules are still
connected to mains. Just as in Rest mode, the device supports the Relight functions.
After a break of 15 minutes, the inhibit mode is automatically reset.

NOTICE
After an exchange of the LED module, the indicator LED remains permanent
RED. The lamp failure indication remains set until a function test has been
successfully completed (automatically with the weekly function test or
immediately by briefly interrupting the power supply or by manually starting
the function test with a test switch (see
)).

The LED module's mains operation does not reset the lamp failure indication.

NOTICE
While the battery is in trickle charge mode and the mains supply is connected,
the micro controller in the emergency unit monitors the charging parameters. If
an error is detected or a parameter is out of tolerance, the indicator LED
switches to fast flashing RED. If the error has been corrected, the indicator LED
immediately switches back to GREEN and continues the charging operation of
the battery.
