6.2. Leds
In case of LEDs the behavior is different to the outputs. The only available configuration is as
follows:
LOGICAL GATE
HMI SYMBOL
OR4
+
NOR4
AND4
&
NAND4
§
Depending on the associated signal the signaling will offer 2 options:
After being switched off, when the relay is switched on again, the LEDs should show the state
just before being switched off. For this reason, and to have as much information as possible, the
LEDs will light up in a different way depending on if the user has recognized the LED before the
switched off or not. To recognize the LEDs, it is necessary to hold RESET key from standby
menu. So, the LEDs will light as follows:
SIGNAL ASSOCIATED TO THE LED KEEPS ITSELF ACTIVATED
The signal that origins the activation of the LED remains activated (the LED and the associated
signal are activated at the same time): In this case the LED will blink at a fixed frequency. Once
the LED is recognized, it will still be blinking with a different frequency.
If after being recognized, the associated signal is deactivated, the LED will be switched off.
SIGNAL ASSOCIATED TO THE LED IS SWITCHED OFF BEFORE BEING RECOGNIZED
If the signal that origins the activation of the LED does not remain activated, once this
associated signal is deactivated the LED will be fixed. Once the LED is recognized, the LED will
be switched off (due to the signal that provoked its activation is deactivated).
By default, the configuration is:
