Description of Parameters and their Settings
Speed setpoint SP4 is set in RPM.
The hysteresis is the margin between condition "excess" (>) and "no excess"
(<), defined by its bandwidth. The hysteresis bandwidth is set as a
percentage of the setpoint in steps of 0.1%.
Setting:
0 : hysteresis above SP4 (recommended when monitoring n < SP4)
1 : hysteresis below SP4 (recommended when monitoring n > SP4)
Without power supply the relays are de-energized (alarm condition). To
consider safety aspects of the application, this No-Power condition can be
assigned to alarm state n > SP4 or n < SP4 condition.
Setting:
0 : OR4 de-energized at ' n < SP4 '
1 : OR4 de-energized at ' n > SP4 '
2 : OR4 de-energized and latched at ' n < SP4 '
3 : OR4 de-energized and latched at ' n > SP4 '
The starter function may be effective for each setpoint individually. Thereby
it is possible, for instance, to disable a low-speed alarm during the starter
phase, whereas a high-speed alarm remains active all the time.
Setting:
0 : starter not effective for setpoint SP4
1 : starter effective for setpoint SP4
At starter condition, the relay may be forced to state energized or
de-energized (if starter function is effective for the alarm).
Setting:
0 : OR4 de-energized
1 : OR4 energized
At sensor fault, OR2 may be forced to de-energized state.
Setting:
0 : no forced state, state acc. to measured speed
1 : OR4 in de-energized state as if n > SP4 (if P07.03 is 1 or 3)
2 : OR4 in de-energized state as if n < SP4 (if P07.03 is 0 or 2)
