22 Installation and initial startup
AZURA® Detector UVD 2.1S Instructions, V6820
4.10 Remote control
The pin header is used for remote control. The single ports transport start,
controland error signals.
4.10.1
Connector assignment
Port Function
GROUND Reference point of the voltage at the signal inputs.
AUTOZERO A signal (short circuit to GROUND) sets the measuring
signal to zero.
ERROR
IN/OUT
The input/output has in idle state + 5V, which is for
both operating directions INACTIVE. If the external
connection is pulled to 0V, the ERROR IN becomes AC-
TIVE. An internal error in the detector causes this port
to be drawn to 0V from the device itself ERROR OUT
becomes ACTIVE.
A possible external wiring with pull-ups is not
necessary.
ƒ
IN: After receiving a signal (short circuit to
GROUND)from an external device, an error mes-
sage appears and the device stops.
ƒ
OUT: An error signal is active for as long as an error
is displayed e.g. the lamp does not start.
GROUND Reference point for external analog control of the
detector.
ANALOG IN 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
GROUND.
Start IN After receiving a signal (short circuit to GROUND) from
an external device, the device starts. If controlled via
software, an electronic trigger is sent via LAN.
4.10.2 Connecting the pin header
To control one device through another, the pin header is used. To use
remote control, you have to connect cables to the pin header. The single
ports are used to exchange control signals.
ƒ
The device is switched off.
ƒ
The power plug is disconnected from the device.
ƒ
Operating tool
Electronic defect
Electrostatic discharge can destroy the electronics.

Wear a protective bracelet against electrostatic discharge and ground.
