Configuration Using the External Trigger Input
The external trigger input can be used to signal the device of one of two events.
Which process is triggered can be configured for each event (see Section
“Configuration Using Web-based Management”).
Before the trigger input can be used in this manner, the power supply to the
trigger input must be switched off.
•
To signal the TRIGGER_PUSH event, apply a voltage to the trigger input
for a period of less than 2 seconds. The signal is triggered when the power
supply to the trigger input is switched off again.
•
To signal the TRIGGER_HOLD event, apply a voltage to the trigger input
for a period of more than 2 seconds. The signal is triggered after approx. 2
seconds.
Switch off the power supply to the trigger input again!
The device ignores when the Mode Membrane button is pressed when the external
trigger input has power. Therefore, always switch off the power supply to the
trigger input after signaling TRIGGER_HOLD.
