Section 8: Troubleshooting
Temperature Sensor Troubleshooting
If the Temperature sensor is reading a few degrees off when
compared to a standard, the Temperature sensor may require re-
calibration. Please refer to calibration procedure in Section 6:
Calibrating the Temperature Sensor.
If the Temperature sensor is reading 255°F, the Temperature
sensor may be disconnected from the Control Module. Check the
cable from the sensor to the Control Module for any cuts or kinks.
Check any splices to ensure good connection. Check the cable
connection to the Control Module.
If replacing a Temperature sensor, all the new Temperature sensors
and any other Temperature sensors connected to the Control
Module should be re-initialized as follows:
1.
Disconnect the temperature sensor from the Control
Module.
2.
Disconnect the power connector from the Control Module
3.
Reapply power to the Control Module
4.
Connect the temperature sensor to the Control Module
5.
Disconnect the power connector from the Control Module
6.
Reapply power to the Control Module
The temperature sensor is now initialized and should be reading the
correct values.
Communication Problems
If the Pegasus is not communicating with the computer software or
the Weather Display, please check the following:
1. Check power connections to the Control Module. Check the
power LED on the circuit board inside the Control Module
enclosure. If the light is not on, make sure the battery
connected to the system is charged. Also check the on-
board fuse. If blown, replace with the spare fuse located in
the middle of the board.
2. Check all communication cable/connectors to be sure they
are firmly connected.
