Bat
LED - is lit when the potential on UPS input falls below 13,8V. Since this input
is used to signal main supply failure, the system flag FS1_ups is raised
simultaneously. The FS1_ups flag may be used in rules processing.
•
Power
LED - is lit all the time the module is supplied with power.
Indicators of
Module status
group are the main sources of visual information about
correct operation of the module.
10.1.8. SET1, SET2 alarm thresholds
The
Alarm thresholds SET1, SET2
group encompasses two LED indicators placed in the
neighborhood of two SET buttons placed on the front panel. The buttons are connected to
analogue inputs A1 respective A2 and indicators are marked as
A1
and
A2
.
Threshold indicators SET1 and SET2 are lit when value of analogue signal at corresponding
input crosses the manually set alarm threshold.
10.2. Unblocking of SIM card
Three failed attempts of entering PIN code locks the SIM card and requires entering the
PUK code. In order to prevent this, the module controls the number of failed attempts
written into SIM card by allowing only two attempts making a third attempt impossible
even if the third attempt was correct.
A double unsuccessful attempt is perceived as a fault requiring user intervention. An
attempt to unlock the module may be performed only when the right PIN code is known.
Necessary procedure:
•
turn the power supply off
•
remove SIM card from the module
•
insert SIM to ordinary mobile phone accepting cards from the operator that issued
actual SIM
•
start the phone and enter proper PIN code
•
if not accomplished before...
- start the module
- insert appropriate PIN into configuration
- power the module off
