- Threshold for starting
the data transmission
This determines how big the change of
the measurement value must be to end
the idle mode.
off /
0,8 to 204 µm


- Stabilisation time for
ending the data
transmission
This determines the time after that the
radio module changes to the idle
mode (*), if the value has not changed.
off /
0.1 sec to
25.5 sec


- Send mea. value after
stabilisation
This determines the maximum number
of retries to send a last value after the
stabilisation of the measuring value until
a confirmation is received.
If the radio module has not received a
confirmation after this number of retries,
it gives an error message.
with 0 to 255
retries
( 0 = no
verification and
no error
message )


(*)Note : In the data transmission mode, 10 measuring values / sec are requested by the ISM-ISi.
In the idle mode no measuring values are transmitted and only 2 measuring values / sec are
requested by the ISM-ISi.
4. Confirmation signals of the gauge radio modules
The gauge radio modules always return a clear optical and acoustical confirmation to the
operator on programming or measurement data transmission. Hence, the operator is immediately
informed whether the transmission was successful or not.
If the transmission was not successful, then the Morse - flashing code of the LED informs the operator
about the cause of error.
The following table explains the confirmation signals returned by the gauge radio modules:
LED
Buzzer
Meaning
1 x green
1 x short
Data transmission successful
1 x red
2 x long
Faulty radio transmission
2 x red
2 x long
Timeout Error on reading the measurement value from the gauge
3 x red
2 x long
Spike on the data line of the Opto-RS232 interface
4 x red
2 x long
No stop-bit from the Opto-RS232 interface
5 x red
2 x long
Parity - error from the Opto-RS232 interface
6 x red
2 x long
Input buffer overflow on the Opto-RS232 interface
7 x red
2 x long
Undefined data format on the Opto-RS232 interface
8 x red
2 x long
Write error on EEPROM access
9 x red
2 x long
Read error on EEPROM access
Note :
Further measurement data cannot be transmitted until the error message has ended !!!
