Diagnostics
11 8 UNT-SVX07D-EN
Error codes appear on the display of the model WDS
sensor when diagnostics occur (see Table 45).
LED1, LED2, and LED3, located on the receiver of all
models, respond to diagnostics by exhibiting specific
blinking patterns. They respond independently of any user
action (see Table 46).
Testing Signal Strength (Wireless Controls)
To initiate a signal strength test, push the Test button on
the sensor (see location of Test button in Figure 43, p. 117).
• Models WZS: LED1, LED2, and LED3 respond by
indicating signal strength. You can view them on the
sensor (Tab le 47) and the receiver (Ta bl e 48).
• Mo
del WDS: Test symbols on the sensor display
indicate signal strength (Ta b le 47). LED1, LED2, and
LED3, on the receiver, respon
d by indicating signal
strength (Ta b l e 48).
Testing Battery Status (Wireless Controls)
Initiate a battery status test as follows:
• On model WZS, push the Test button on the sensor (see
lo
cation on Figure 43, p. 117 ). LED5 on the sensor
responds by indicating the leve
l of battery strength, as
