Sensor/Receiver Compatibility

Version 1.5 (p/n X13790854 and X13790855) and higher receivers are compatible with all sensors
models and support all functions. Receivers released prior to version 1.5 are compatible with only
models WTS and WZS.

Replacing a Failed Sensor or Receiver

To replace a failed sensor or receiver:
1. Confirm that the device is disassociated (see
2. Set the rotary address switch of the new device to match the address of the remaining sensor
3. Apply power to the new device. Association between the new and the remaining devices will
Note: When replacing a WDS sensor, the receiver (version 1.5 or higher) will automatically

Servicing and Testing

If the wireless sensor system is not working as expected, use the tools and procedure described
in this section.

Servicing and Testing Tools

No special tools or software are necessary to service and test the wireless sensor system. Test the
system by using:

Procedure for Testing the Wireless Sensor System

If the wireless sensor system is not working as expected:
1. Observe LED5 on the receiver. LED5 is On solid green whenever the receiver is

placed into configuration mode and the factory default configuration is still valid. If the
sensor configuration does not match the desired system features, it can be manually
configured (see "Manual Association," p.

• Models WTS, WZS: LED5 should turn On solid green, indicating proper battery strength.
LED1, LED2, and LED3 will indicate signal strength.
Note: When checking signal strength, both LED1 and LED3 on the receiver and sensor
illuminate in unison if the sensor and receiver are associated. Use this feature to
confirm association.
