D-R 290
Fig. 7.16: Device status
The status of the measuring device shows the currently measured LED current, the
measurement status and the positions of the zero point reflector and turntable.
An explanation of the status codes can be displayed as Quick Info [} 196] (hover the
mouse cursor over the start of the line).
The
D‑R 290 has three temperature sensors. These measure:
● the printed circuit board temperature
● the temperature of the LED
● the temperature of the measuring head close to the stepper motors
If the sensed temperature undershoots the respective temperature setting, a heating
element is activated for the respective component.
The
D‑R 290 has combined analogue/digital inputs for purge air monitoring. The de
vice connected between pins 1 and 2 of the respective plug (see
[} 144
]
) can option
ally be:
● a 4-20 mA analogue transmitter for purge air measurement
or
● a NO contact for purge air
monitoring.
In this case an internal short-circuit detection leads to a display of the purge air flow as
exactly 100.0%.
If the D-SK AE is connected as shown in
Fig. 5.23 the NO contact indicates "Purge air
on".
The other parameters are provided for future connection of analogue purge air meas
urement.
