70 / ACCESSORY SENSORS
HIGH/LOW ALARM
Sets the RPM value at which a high/low RPM warning error is generated.
The value is entered in RPM.
HIGH/LOW ALARM DELAY
Establishes the delay between the detection of a high/low RPM alarm
condition and the resulting alarm display. The value is entered in seconds.
RPM CONSTANT
The number of pulses per shaft revolution. If the sensor is mounted directly
to the shaft, the value is 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
Filters 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 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.
