9.9.4Save user settings restore with PIN 9090
Save User Setup
The individually made device con  gurations (User Settings) can be saved
and, with the corresponding PIN input (9091), can be reestablished.
By entering
PIN 9090 the individually made device con  gurations can be
reestablished ( F Start - PIN Input).
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!
9.9.5 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). Indi-
cated 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 distur-
bances as “ Alarm ” alternating to the actual value and
stored in the menu of “ Events ” .
Indication via relays is possible ( F IO Setup / function
relay outputs).

9.9.6 Limit
Limit
After allocation of a digital input ( F 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 opera-
tion by time switch).
Setting range: “ Limit ” = “ n-max ” up to “ n-
min ” .
Factory setting: 100 % ≙ max. modula-
tion, i. e. no limit.
Setting depending on device tye in: % or
rpm.
