110 / SYSTEM CONFIGURATION
LOW ALARM
The Low Alarm option sets the RPM value at which a low RPM warning
error is generated. The value is entered in RPM.
HIGH ALARM DELAY
The High Alarm Delay establishes the delay between the detection of a high
RPM alarm condition and the resulting alarm display. The value is entered
in seconds.
LOW ALARM DELAY
The Low Alarm Delay establishes the delay between the detection of a low
RPM alarm condition and the resulting alarm display. The value is entered
in seconds.
RPM CONSTANT
The RPM Constant is the number of pulses per shaft revolution. If the
sensor is mounted directly to the shaft, the value will be the number of
pulses generated by the sensor per revolution of the shaft itself. If the
sensor is mounted elsewhere, a gear or sprocket ratio must be calculated
and entered into the RPM constant.
RPM FILTER
The RPM filter value is used to filter the signal out of the RPM sensor.
Typically no filtering is required so the standard value is set at 0%. If the
RPM readout on the Main Work screen is oscillating in excess of 10%,
increasing the filter value will filter the signal to reduce the oscillation. For a
true RPM value this number should be set to 0%.
DISABLE CONTROL ON LOW ALARM
The setting for Disable Control on Low Alarm shuts down ALL active control
channels if the RPM value of the selected sensor falls below the low alarm
level setting.
The two settings include:
• ENABLED allows the control channels to be shut down when the RPM
value falls below the low warning setting.
• DISABLED will disable the function. The control channels continue to
operate normally regardless of the RPM value. However, when the low
RPM state occurs, the information alarm still occurs.
