OFL Message - Overflow
When an RPM higher than 9999 is reported, OFL is displayed. The OFL message remains until the reported RPM drops below 9999.
Monitor Head
Situation:When power is supplied, the Tachometer does not power-up.
Solution:
1. Check that the power cable is connected correctly.
2. Check the 3 Ampere fuse.
3. Check that there is at least 12.5 volts between the red and black wires of the power cable
4. Replace the Tachometer
Splitter Box
Situation:With the Splitter box connected, the Tachometer will not power up.
Solution:
1. Check that there is power to the Splitter Box; power light.
2. Check that the arrow of the Extension cables are properly aligned.
3. Replace the Extension cable.
4. Replace the Splitter Box.
Single Sensor Adapter Cable
Situation:With the Single Sensor Adapter cable connected, the Tachometer will not power up.
Solution:
1. Check that the arrows of the Extension cables are properly aligned.
2. Replace the Extension cable.
3. Replace the Single Sensor Adapter cable.
Bin and Proximity Sensor
Situation:The Tachometer never indicates an alarm when the product bin is empty or full.
Solution:
1. Ensure product has not built-up between or “bridged” over the Bin sensor eyes.
2. Ensure the High Alarm, Low Alarm and Cal values are set correctly.
3. Swap the Sensor cable and replace if necessary.
4. Replace the Bin or Proximity sensor.
Situation:The Tachometer always indicates an alarm when the product bin is full or empty
Solution:
1. Ensure the product has not built-up or “bridged” over the Bin sensor eyes.
2. Ensure the High Alarm, Low Alarm and Cal values are set correctly.
3. Swap the Sensor cable and replace if necessary.
4. Replace the Bin or Proximity sensor.
Situation:When a Bin or Proximity sensor channel is selected nothing but 0 is shown
Solution:
1. Bin and Proximity sensors only report to the Monitor Head when the tank goes empty or full; depending on calibration. Nothing but 0 is ever shown.
Shaft Sensor
Situation:The Tachometer displays no RPM on one or more channels
Solution:
1. Ensure the Shaft sensor is plugged in and powered; the power light.
2. Ensure the magnet is still on the shaft.
3. Ensure the Shaft sensor is still in-line with the target
4. Check that the Shaft sensor is within the required distance from the target.
5. Ensure the High Alarm, Low Alarm and Cal values are set correctly.
6. Swap the Sensor cable and replace if necessary.
7. Replace the Shaft Sensor.
Situation:When a shaft stops turning, the Tachometer does not indicate an alarm, but an RPM is displayed.
Solution:
1. Ensure the Low Alarm value has not been set to zero. If the Low Alarm value is zero, the alarm is disabled.
Situation:The Tachometer always indicates an alarm even when the shaft is turning.
Solution:
1. Ensure the Low Alarm value is not higher than the RPM reported by the Shaft sensor.
2. Ensure the High Alarm value is not lower than the RPM reported by the Shaft sensor.
3. Ensure the Cal value is equal to the number of target passes in one revolution.
Situation: The Shaft sensor produces an RPM, but it is erratic and incorrect.
Solution:
1. Ensure the Cal value is correct otherwise the RPM will not read correctly.
2. Ensure the Shaft sensor is still in-line with the target.
3. Ensure the Shat sensor is within the required distance from the target. When the Shaft sensor is at an extreme distance limit, this may occur.
4. Ensure there is power to the Shaft sensor; the power light.
5. Check the sensor cable. Set the Cal value of the Shaft sensor channel to zero, the Low Alarm value to zero, and the High Alarm value to one. Align a magnet in front of the Shaft sensor. Begin flexing and shaking the Sensor cable. If an alarm occurs, replace the Sensor cable.
6. Replace the Shaft Sensor.
Situation:When a Shaft sensor channel is selected only OFL is displayed
Solution:
1. Ensure the Cal value is set correctly.
2. Check the shaft RPM. If the reported shaft RPM is over 9999 this will occur.
