Maximum Alarm Level [4112]
In this menu the set “Maximum Alarm Level” is shown (on
the right-hand side of the display - area F). At the same time
the actual value of the shaft power (%) is viewed on the left-
hand side of the display (area F), the value within brackets.
Since the actual shaft power is always visible in this menu, it
allows you to easily setup a suitable maximum alarm level.
The value of the maximum alarm level is given as a
percentage of the nominal motor power [223], i.e. a step of
1% is equal to 1% of the nominal motor power. If the actual
shaft power (shown within brackets in the display) exceeds
the set alarm level, the “Maximum Alarm Delay” timer,
menu [4113], will start counting down. If the shaft power is
still above the limit when the delay time has elapsed, an alarm
will be generated according to the selected “Maximum Alarm
Action” in menu [4111].
This menu can be set manually to the required alarm level, or
it can be set indirectly, by performing an “Autoset”.
See further information in Fig. 40, page 57. .
Example:
The “Max Alarm Level” is set to 80%. This means that when
the output shaft power exceeds 80% of the nominal motor
power, the alarm delay timer starts counting down.
Maximum Alarm Delay [4113]
When the load level exceeds the alarm level for a continuous
period longer than the set “Max Alarm Delay” time, the
selected “Maximum Alarm Action” in menu [4111] is
activated.
Maximum Pre-Alarm [412]
These menus contain the settings for the load monitor
maximum pre-alarm.
Maximum Pre-Alarm Action [4121]
Setting of the alarm behaviour when a “Maximum Pre-
Alarm” has been detected.
Maximum Pre-Alarm Level [4122]
The value of the maximum pre-alarm level is given as a
percentage of the nominal motor power [223]. When the
actual shaft power (shown within brackets in the display)
exceeds this level, the “Maximum Pre-Alarm Delay” timer,
menu [4123], will start counting down. When the delay time
has elapsed, an alarm will be generated according to the
selected “Maximum Pre-Alarm Action” in menu [4121].
This menu can be set manually to the required alarm level, or
it can be set indirectly, by performing an “Autoset”. See
further information in Fig. 40, page 57.
Maximum Pre-Alarm Delay [4123]
When the load level exceeds the alarm level for a continuous
period longer than the set “Max Pre-Alarm Delay” time, the
selected “Maximum Pre-Alarm Action” in menu [4121] is
activated.
