Using the Wireless Sensor System to Check
Signal Strength on a Site (Wireless Controls)
Follow these steps to check the signal strength on a site:
1. Power up a receiver with a 24 V transformer (user
supplied)
2. Associate the sensor to a receiver of the same model
intended for the job
3. Place the receiver at the desired location
4. Place or hold the sensor at the desired location
5. Press the Test button (S5) on the sensor and observe
the signal strength as indicated by LED1, LED2, and
LED3 on model WZS, and on the display on model
WDS (Figure 62, p. 95).
