Operations
Possible Alarms
Alarms occur whenever a threshold level (high or low) has been exceeded. You can
configure these threshold levels as well as the type of alarm (major, minor, or
disabled) that is caused.
Input Low Threshold
If you are experiencing an Input Low Threshold alarm,
1. Check the levels on the Sensor Tab shown on page E-11 .
2. Compare the levels on the Sensor Tab with the thresholds set by using the Rx
Configuration Tab on page E-12 .
Remember that the input level of the online unit must be greater than the level of
the offline unit.
3. If your Rx Input level has exceeded the Input Low Threshold, you might have lost
track of the satellite.
Supply Voltage
If you are experiencing a Supply Voltage alarm,
1. Check the levels on the Sensor Tab .
2. Compare the levels with the thresholds set by using the Rx Configuration Tab .
3. If your levels indicate a lack of supply voltage,
•
Check to ensure that the unit is being supplied power via the J2 and J3
connectors.
•
Check the power supply to ensure that it is not being overloaded.
An overloaded power supply can cause the short-circuit protection to activate.
Check what is connected to J4 and J5 for short circuits.
•
There could be a problem with the unit itself
In this case, contact Technical Support
Current Consumption
If you are experiencing a Current Consumption alarm,
1. Check the levels on the Sensor Tab .
2. Compare the levels with the thresholds set by using the Rx Configuration Tab .
3. Verify that the levels are consistent with specifications for the LNB.
If they are not, you might have a problem with your LNB. Contact the LNB
manufacturer for support.
