Information
By entering the “PIN 9095” in the “PIN” menu of the “Start” menu group the device is reset to the as-
delivered state (except for the saved events in the “Protocol”menu).
Any changes that have been made to the settings are thus lost.
9.4.4 Sensor Alarm ON / OFF
The inputs “E1 Analogue In” and if Sensor 2 is activated “E2 Analogue In” are monitored.
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.
Function only in controller mode (from
2.01 )!
Controller Setup With “Alarm Sensors” = “ON” (factory setting). Indicated
sensor disturbances are displayed as “Alarm” alternating to
the actual value and stored in the menu of “Protocol”.
A programmed alarm relay (factory setting relay K2) indicates
the sensor failure.

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

The limitation influences both outputs in operation with two control circuits.

Limit
“Limit value” = max. possible modulation (e.g.
speed reduction during night operation by
time switch).
Setting range: “Limit” = “Min. Speed” to “Max.
Speed”.
