RESET sensor and assign default serial address (=127)
To restore the sensor serial address to the default value, proceed as follows:
1.
Place the magnet near magnetic switch SW1, the green LED will come on.
2.
Hold the magnet in position until the green LED goes off and the yellow
LED comes on (after approx. 6 to 10 s);
3.
Immediately remove the magnet from the sensor and at the same time
move the CLEAN switch (SW2) up, making sure the yellow LED fl ashes a
few times.
4.
Move the CLEAN switch to the OFF position and make sure the yellow LED
completes a rapid sequence of fl ashes (RESET COMPLETE);
Otherwise repeat the procedure.
To check that the sensor has eff ectively been reset, proceed as follows:
1.
Make sure the Access Point wireless network is closed (L1 fl ashing slowly
1 s);
2.
Stimulate the switch SW1 with the magnet;
3.
Check that LEDs come on in the following sequence:
-
green LED (1 sec.);
-
yellow LED (4 to 5 sec.);
-
green LED (15 sec.);
-
red LED (1 sec.);
Completing the reset procedure and assigning the default serial address
returns the sensors to the same status as a new device.
To assign a new address, repeat the serial address assignment procedure.
Note:
1.
The sensor can only be reset if it has already been bound to an Access
Point.
2.
Note that, after resetting the sensor, the number of devices set for the Access
Point remains unchanged. Realignment will occur after a maximum of around
2 hours.

The following table describes how the LEDs fl ash whenever SW1 or SW2 are
stimulated or when data is transmitted.

Note: the LED is two-colour, red and green, which becomes yellow when both
LEDs are on at the same time. There may be diff erent shades of yellow due to
diff erent tolerance in the brightness of the red and green LEDs.

2.3 Sensor activation

When the sensor is put in SLEEP mode using the rTM SE handheld during
the procedure to assign the serial address (no transmission-minimum power
consumption), the sensor is eff ectively in standby; nothing is transmitted
until movement of the CLEAN switch is activated (sleep status). Activation is
not reversible, and the sensor will send the temperature measured every 16
min (default value) if the Access Point that the sensor has been bound to is
switched on.
To exit sleep mode, proceed as follows:
•
Power up the Access Point;
•
Move the CLEAN switch to the ON position (SW2);
•
Make sure the red LED comes on for a few seconds.;
•
When the red LED comes on immediately the CLEAN switch to the OFF
position;
•
The LED on the sensor remains on until it has connected to the Access Point.
If the operation fails, the sensor returns to sleep mode, if however it's successful
normal operation will resume, with data being sent every 16 min.
Check operation by stimulating the sensor.
Resetting the sensor in sleep mode
If the sensor needs to be reset when in sleep mode (Access Point network
parameters forgotten), proceed as follows:
•
Move the CLEAN switch to the ON position (SW2);
•
Wait for the red LED to come on;
•
Stimulate SW1 continuously while the red LED remains on.
•
Keep SW1 stimulated until the LED fl ashes (yellow) ;
•
Remove the magnet from SW1 and move switch SW2 back down.
•
Reset completed.

Parameters and functions
The BP wireless sensor reads the temperature and manages the associated
alarms at one minute intervals.
The data is then transmitted at the intervals set by parameter, according to the
application and the expected battery life. The sensors work most of the time in
low power mode, so as to save battery power. They are activated to make the
measurements and send the data at the preset time.
Activate switch SW1 to send the sensor data manually, or check the connection.
The CLEAN button is used to set cleaning status or deactivate the showcase,
thus disabling the high temperature alarms.
When returning from CLEAN mode, the high temperature alarms are disabled
for a time equivalent to the auto-confi guration cycle (AUTO_DELAY).
