4.8.4 OSDs STATUS & RESTART STATUS outputs (terminals 5, 6 & 7)
The OSDs STATUS and RESTART STATUS outputs provide the same information as the
LEDs indicators located on the front cover of the module. These outputs provide remote
indications on the muting module status.
PROTECTIONS
•
The OSDs STATUS and RESTART STATUS outputs must be protected by an external
2.5 A max. fuse connected on terminal 32 (+24 V OUTPUT).
•
OSDs STATUS and RESTART STATUS outputs are not protected against short
circuits. Short circuits may damage these outputs, but the module will still operate
correctly.
PROTECTION AGAINST OVERLOADS
•
The OSDs STATUS and RESTART STATUS outputs are protected by circuit breakers
which are triggered by an accidental overload.
•
In case of accidental overload, eliminate the failure and reset the muting module to
reactivate the OSDs STATUS and RESTART STATUS outputs. Then reset the module by
switching off and on the power, or by pressing the RESET push-button located on the
front face cover of the module (see chapter 2.4.7 Reset push-button). Finally, restart the
module by pressing and releasing the restart push-button (see chapter 2.4.5 Manual
restart of the module).
•
In case of accidental overload, the LEDs status indicators located on the front cover of
the module keep operating correctly and the muting is still allowed.
