RCF ST 15-SMA II [8/16] Failure indication and safety

ENGLISH

The microprocessor is able to signal three different kinds of failure by ﬂashing the “Limiter”

red LED on the ampliﬁer panel before the lighting up of the “Power status” green LED. The

three types of failure are: WARNING: a non severe error or auto-ripristinate malfunction

is detected and the performance of the speaker is not limited. LIMITATIONS: an error is

detected and the performance of the speaker is limited (the sound level is reduced by 3 dB).

This does not affect the operation of the speaker since it continues to operate. However, it

is necessary to call the service centre to solve the issue. FAILURE: a severe malfunction is

detected. The speaker switches to “mute”.

FLASHING INDICATION: 1 or 2 >Warning 3 or 4 >Limitation from 5 to 8 >Failure.

In case of failure, the “Ready” green LED remains off.

Perform the checks listed below:

- check if the speaker is properly connected to the power supply

- make sure that the power supply is of correct voltage

- check that the ampliﬁer is not overheated

- disconnect the speaker from the mains power supply, wait for a few minutes and connect

it again. If after these tests the red “LIMITER” LED is still on, please contact an authorised

service centre.
