The topics in this section provided the common troubleshooting procedures for XR Transmitters. In addition to this
section, refer to the diagnostics codes available withing the LCD panel menu.
General Troubleshooting
Signal reception problems - system is configured for use with a GPS Receiver
Recommended action
1. Verify that the GPS receiver is properly connected to the transmitter.
2. Verify that the GPS receiver is properly mounted on a non-low-E glass window or on a rooftop or pole outside with
a clear view of the sky.
3. From the transmitter's LCD panel, verify its time source communication status.
l
Check to assure that the GPS communication indicator
is showing on the display. If this symbol is displayed,
then the transmitter is communicating with the GPS receiver.
l
If the GPS communication indicator
is NOT displayed, then the transmitter, GPS receiver, or the connection
between transmitter and GPS receiver is defective. Check the GPS cable connections.
l
If the GPS communication indicator
is displayed but the three parentheses symbol
is not displaying a
sequence in motion, then the problem is with the GPS receiver or with its signal reception. Check to make sure
that the GPS receiver has a clear view of the sky and that its view is not obstructed.
GPS installation considerations
l
The use of unshielded or standard shielded cables to extend the distance between the GPS receiver and the
transmitter beyond 50 feet can cause this failure mode. A special shielded cable with low resistance on the
voltage supply line is required for distances over 50 feet. The maximum distance using the special cable is 200
feet. If cable connections are good, replace the GPS receiver.
l
Double pane low-E glass windows are coated with a transparent metal layer that reflects infrared heat rays; this
will also reflect the GPS signal. The GPS receiver will not receive the signal through low-E windows.
When certain types of electronic light ballasts become defective they may radiate broadband noise, which can interfere
with wireless devices. While interference issues are unlikely with the Primex Wireless Clock System, high levels of noise
present in the 72-76MHz range could potentially cause clocks which are located far from the transmitter and also within
the close proximity of these ballasts to not receive a signal. Very limited instances have occurred in the past, which has
only been found to happen when ballasts become defective.
The transmitter or other system components may have experienced a potential lightning strike.
Recommended action
If you suspect your system has been struck by lightning, contact Primex Wireless Technical Support.
The transmitter front display does not light up.
This may be due to the an issue with the transmitter's power supply.
Recommended action
If the display does not light up, check the power supply connection to the transmitter and to the 120 VAC outlets.
