Hardware – Chapter 6
As in this range the DC offsets of the channels
have to
be compensated, a range of
about 16000 resp. ±8000 units is usable. Further information may be found in chap
-
ter 8 on page 28 (CAN Bus) resp. chapter 9 on page 45 (Profibus).
6.4 The Control LEDs
On the front panel a group of 5 LEDs can be found.
Figure 2
Position of the LEDs
PWR: Green, presents the power voltage of the device
CD1, CD2: Yellow, show the exceeding of the sum voltage and the set thresh
-
olds for channel 1 and 2.
The green LED (BUS) and the red LED (ERR) behave differently depending on the in
-
terface, CANopen® or Profibus.
6.4.1 CAN Bus (HG G-73350)
The green LED (BUS) flashes after turning on the device. It shows the status of
the device:
–
Node stop:
LED flashes slowly
–
Node reset communication
and
node preoperational:
LED flashes fast
Node operational:
LED is lit continously
–
The red LED (ERR) starts to flash as soon as a CAN bus error occurs. Addi
-
tionally the red flashing LED displays an error in the set of parameters.
6.4.2 Profibus (HG G-73351)
BUS: Green, is lit while data is exchanged with the Profibus master.
ERR: Red, is activated if one of the following error conditions occurs:
–
EEPROM parameter checksum is not correct.
–
Profibus protocol chip hardware error.
–
Profibus buffer error, if modules other than those specified in the GSD file
are displayed.
CD1/CD2 lights up if there is a sum level, but a wire break on the differential
channel has been detected.
