Buzzer
The status and the faults of the TRI POWER X33 HE are signalled by the buzzer, which will emit a sound according
to the various operating conditions of the TRI POWER X33 HE.
The various kinds of sounds are described below:
Sound A: This signal is emitted when the TRI POWER X33 HE is turned on or off using the apposite buttons. A
single beep confirms the start-up, the activation of the battery test, and the cancellation of the
programmed switch-off. By keeping the power-off button pressed, the buzzer will emit in rapid succession
sound A four times, before confirming the switch-off with a fifth beep.
Sound B: This signal is made when the TRI POWER X33 HE commutates to bypass in order to compensate the
surge current due to the insertion of a distorting load.
Sound C: This signal is emitted when the TRI POWER X33 HE switches to battery operation, before the low battery
signal (sound D). It is possible to silence the signal (see the “Graphic display” paragraph).
Sound D: This signal is made during battery operation, when the low battery threshold is reached. It is possible to
silence the signal (see the “Graphic display” paragraph).
Sound E: This signal is emitted in the presence of an alarm or lock.
Sound F: This signal is emitted if a battery overvoltage fault occurs
Sound G: This signal is made when the battery test fails. The buzzer beeps ten times. The alarm signal is
maintained with the “replace batteries” LEDs on.
