Testing Battery Status (Wireless Controls)
Initiate a battery status test as follows:
• On model WZS, push the Test button on the sensor (see
location on Figure 62, p. 95). LED5 on the sensor
responds by indicating
the level of battery strength, as
shown in Tab l e 42, p. 96.
• On model WDS, push the Test button on the sensor
(see location on Figure 62, p. 95). In response, a battery
test symbol appears on the display. The symbol shown
indicates battery life expectancy (see Tab le 43).
24 V Power Status Indicator (Wireless Controls
LED5 on the receiver of all models (Figure 61, p. 94) lights
and stays constantly On when 24 V power is normal.
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 recei
ver 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).
