3.1 PIN CONNECTIONS OF ALL UV VERSIONS
Pin connection scheme of the connector
[color of wire in yellow connection cable]:
1 - V+:
positive supply for signal circuit,
[red] 7 - 18 V, 1 W
2 - HEAT-GND: heater ground
[blue]
3 - UV-X-OUT: UV-B or UV-E output, 0 - 3 V
[green] not connected in UVS-A-T
4 - TEMP-OUT: internal temperature output
[yellow] see table in Appendix II
5 - GNDA: ground for signal outputs
[grey]
6 - HEAT V+: positive supply voltage for heater
[brown] 7 - 18 V, 8 W
7 - UV-A-OUT:
UV-A output, 0 – 3 V
[white] not connected in UVS-B-T or -E-T
8 - GNDA:
ground for signal circuit
[black]
Voltage drop over connection wires:
For correct operation of the sensor it is required that
the power supply and the connection cable have a total
resistance which does not exceed a critical value R
max.
This is to prevent voltage drop over the connection
wires that will reduce the supply voltage beyond the
lower operating limit of the radiometer electronics.
