Operation
Excess Temperature Handling TO
The TO parameter defines the behavior of the read/write device in the event of excess tempera-
ture. The parameter can be used to protect the device in the event of excess temperature.
ParamTyp:
Default:
Value range:
Value
0
1
2
Caution!
The read/write device cannot identify tags during a pause.
It may be possible that data is not read if tags move quickly through the sensing range.
Example
WP1QTO.00.01.02 sets the behavior to "reduce duty cycle" in the event of excess temperature.
RP1QTO.00.00 reads out the specified behavior.
AF AFI to Request
The AF parameter can be used to filter tags by the AFI value. This means that only the relevant
tags can be addressed out of a large number of tags.
ParamTyp:
Default:
Value range:
TO
TO = 0
0 = switch off
1 = reduce power
2 = reduce duty cycle
Meaning Description
Switch off The read/write device switches off when the internal device tem-
perature is over 85 °C.
The device will switch back on when the internal temperature falls
below 80 °C.
Reduce Power The read/write device gradually reduces the transmission power
when the internal device temperature is between 80 °C and 85
°C. A reduced transmission power reduces inherent heating.
The read/write device switches off when the internal device tem-
perature is over 85 °C.
Reduce duty The read/write device pauses for approx. 0.5 seconds after a
cycle complete pass if the internal device temperature is between 80
°C and 85 °C. This reduces inherent heating. The length of the
pause varies with the internal temperature and the duration of the
read/write command executed
The read/write device switches off when the internal device tem-
perature is over 85 °C.
