FUNCTIONAL DESCRIPTION
-
NORMAL OPERATION
The right or left channel is activated by the corresponding position of the direction indicator through the
direction input pins. Each time an output (or both) is activated, the buzzer is also activated through the
BUZZ pin at the double frequency than the output(s). In emergency case, if the emergency button is
activated the two channels are turned on. At the same time the emergency red LED is flashing. An
anti-theft alarm can be connected to the AL pin, in that condition if the anti-theft alarm is used the two
channels are activated.
-
UNDER-VOLTAGE OR OVER-VOLTAGE CONDITION
In case the device detects an undervoltage or an overvoltage condition the activated channel(s) are
automatically switched off whatever the input commands (LDIR, RDIR, AL, EM)
-
TRAILER OPERATION
The trailer detection is achieved with the ROL external resistor. In that case the green trailer LED is
flashing through the pin LEDT in synchronism with the outputs.
-
LOW LOAD CONDITION
The low load detection is achieved with the ROL external resistor connected between ROL pin and RT pin.
If a low load condition has been detected the output flashing frequency on the guilty channel and the
buzzer frequency will be double (in direction mode only) .
-
POWER LIMITATION CONDITION
In case of overloading of the power outputs the duty cycle is reduced internally by the device itself so as to
keep maximum junction temperature within safe limits.
-
CHIP GROUND DISCONNECTION
If GND pin is disconnected, the device will switch off provided V
bat
does not exceed 18V.
