the safe state (trip limit exceeded) is indicated with a red LED. If the trip condition is not
met, the LED is switched off.
Test values
Active test values are indicated with a yellow LED. Click Details to open Service-Status to
get further information on the test values.
Warnings
Applied warnings are indicated with an orange LED. Click Details to open Service-Status to
get further information on the warnings.
Error
Applied errors are indicated with a red LED. Click Detailsto open Service-Status to get
further information on the reason of the error.
Group Plant status
Direction of rotation OK
This LED indicates whether or not the recognized rotational direction corresponds to the
configured preferred rotational direction. When the shaft turns in the correct direction,
the LED is green. The inverted rotational direction effects the LED to be red.
Standstill
After the standstill time – defined on Configuration → Basic Settings → Standstill
detection – has elapsed, the LED is on. If, after a standstill, a pulse is detected at the signal
input, the standstill message is reset.
Maximum speed
In this field the maximum measured speed is indicated. Use command Monitor → Reset
speed peak to reset this value to zero. A corresponding access authorization is required.
Group Physical state of digital outputs
This field shows the physical state of the six digital outputs. For each output the logical
condition (for example: Standstill) and the operating principle Open-circuit mode or
Closed-circuit mode are shown. An activated output is indicated with a yellow LED. Based
on the chosen operating principle an output may be physically active (switched) even
when the logical condition for this output is not met.
Group Monitor information
In these fields statistical values, the current temperature, and the maximum temperature
measured with the internal temperature sensor are displayed.
Reboots (<24 h)
This counter increases when an internal fault is detected. If no further faults are detected
within the next 24 hours, the counter is reset to 0. If altogether 5 faults are detected, the
monitor is switched off.
