Installation and initial startup
AZURA® Detector UVD 2.1L instructions, V6831
Plug
Function
Error IN
TTL input
Low active
Secure switching threshold at least 10 mA
After receiving a signal (short circuit to ground)
from an external device, an error message appears
and the device stops.
Start IN
TTL Input
Low active
Secure switching threshold at least 10 mA
After receiving a signal (short circuit to ground)
from an external device, the device starts. If con-
trolled via software, an electronic trigger is sent via
LAN.
Autozero
Low active
Secure switching threshold at least 10 mA
A signal (short circuit to ground) sets the measuring
signal to zero.
+5V
Provides a voltage of 5 V with respect to GND. This
makes it possible to supply an appliance that is
switched by an EVENT.
Max. current: 50 mA
GND
Reference point of the voltage at the signal inputs.
+24V Valve
Event controlled switching of 24 V against GND
Max. current: 200 mA
External λ
Allows external analog control of the detector
when the option ANALOG has been selected in the
SETUP menu.
The control voltage must be applied against
AGND.
Voltage range: 0-10 V
The scaling can be changed by the user.
AGND
Reference point of the voltage at the input external λ.
