Troubleshooting
7.1.
Device responses in error situations
The idOil-30 3G and idOil-30 Battery 3G units send a text message response to any
commands they receive. At times, the text message command sent by the user may be
erroneous, in which case the unit responds with an error message to the user’s mobile
phone.
Possible reasons for error messages are listed below.
Error state/message
Possible cause
No response
The 3G modem is not connected to the
network. The signal strength bar must be
visible on the local display. If this is not the
case, it is possible that the signal is too
weak or the SIM card’s PIN code is
incorrect.
COMMAND ERROR
The command was entered incorrectly.
COMMAND SYNTAX ERROR
The command is correct, but there was an
error in the parameter entry. The reasons for
the errors vary between commands.
Possible causes include the following:
the point is missing from between the
numbers
there are too many numbers for the free
memory slots
too many characters
the point or colon is missing
the sensor input number is not 1...3
the separator characters are missing or
are incorrect
the data/time entered is invalid
the entered value deviates from the
allowed values
Solution: Enter a new text message command and check before sending that it has been
entered correctly.
7.2.
Resetting the message counter (RSTC)
The total number of messages sent by the device within 24 hours is limited to 50. If the
device is not sending any messages, it is possible that the message counter has reached
its limit.
To reset the counter and resume message traffic with the device,
send the following text message to the idOil unit:
