Information
By entering
“
PIN 9095
”
in the
“
PIN
”
menu in the
“
start
”
menu-group, the device is entirely
reset to the pre-delivery condition.
Any changes that have been made to the settings are thus lost!
9.8.5 Sensor Alarm ON / OFF
Function only in controller mode (
2.01
)!
For “ E1 Analog In ” and if activated for sensor 2 “ E2 Analog In ” .
In case of an interruption or short-circuit in the sensor conductor, or in case of measured values that
lie outside of the device
’ s measurement range, a time-delayed fault indication takes place.
Alarm sensors
With “ Alarm Sensors ” = “ OFF ” (factory setting). Indicated
sensor disturbances are displayed as “ Message ” alternating
to the actual value and stored in the menu of “ Events ” .
Sensor 1
Alarm sensors
With “ AlarmSensors ” = “ ON ” areindicated sensor disturban-
ces as “ Alarm ” alternating to the actual value and stored in
the menu of “ Events ” .
Indication via relays is possible ( IO Setup / function relay
outputs).

9.8.6 Limit
Limit
After allocation of a digital input ( IO Setup) an adjustable limitation of the modulation
can be activated via a digital input ( “ D1 ” , “ D2 ” , ..).
As long as no allocation has been carried out “ IO Setup ” . Display:

“ Limit value ” = max. possible modulation (e.g.
speed reduction during night operation by
time switch).
Setting range:
“ Limit ” = “ n-max ” up to “ n-min ” .
Factory setting: 100 % max. modulation, i.
e. no limit.
