SS-04-24 light signalization Karosa
The light signaling function is described using a flowchart. Signaling serves to inform the driver and passengers of the need to stop the car (emergency, stroller, invalid, stop).
The light outputs are rated for the power loads listed below. If the above values are exceeded (eg circuit breaker short-circuit), the overloaded circuits are disconnected, each branch separately.
Button input circuits are designed to trigger the required function by connecting the corresponding input to the vehicle's body frame (to the negative terminal of the battery).
Canceling the selected functions will cause a door level or impulse signal.
Level signal: closed door ... disconnected or grounded input
Open door ... + 24V
Impulse signal: closed door ... disconnected or grounded input
Open door ... descending edge + 24V Þ 0V
Acoustic signaling is provided by an internal loudspeaker
Function description:
STOP - when the "STOP" button is pressed, the "BELL" indicator lights up in the driver's panel, the info-STOP lights up over the door and the acoustic signal sounds brief (2.5 seconds). The optical signaling is canceled by opening the door. If the "STOP" button is pressed again, the audible alarm is no longer responding. When the "STOP" button is pressed, the electronics still responds to the "EMERGENCY" button. The output of the electronics connects + 24V to the "STOP" bulbs.
INVALID - When the invalid button is pressed, the indicator "INVALIDA" flashes in the driver's panel and the info-STOP flashes above the door. The driver sounds an acoustic signal (the same tone as a stroller). The optical signaling is canceled by opening the door. Pressing the "INVALIDA" button again will sound an acoustic signal. When the "INVALIDA" button is pressed, the electronics still responds to the "EMERGENCY" button. The output of the electronics connects + 24V to the bulbs "INVALID".
STROLLER - When the push button is pressed, the "STROLLER " indicator flashes in the driver's panel and the info-STOP flashes above the door. The driver sounds an acoustic signal (the same tone as a stroller, other than a stop). The optical signaling is canceled by opening the door. If you press the "STROLLER " button again, acoustic signal sounds. When the "INVALID" button is pressed, the electronics still responds to the "EMERGENCY" button. The output of the electronics connects + 24V to the "STROLLER" bulbs.
EMERGENCY - After pressing any Emergency Button, the "Emergency" button lights up over the door, the driver sounds intermittently with the acoustic signal. The optical and acoustic signaling is canceled by opening the door. When you press "NOISE", the electronics do not respond to other buttons. The output of the electronics connects + 24V to the "EMERGENCY" bulbs.
