6. Estimated isolation resistance between positive ter-
minal of the battery and chassis; unit expressed in kΩ.
The two values on the left side of the home screen re-
ports the polled values of the negative terminal of the
battery. The two values on the right side of the home
screen reports the polled values of the positive termi-
nal of the battery. The two values in the center of the
screen (yellow text) reports the energy stored in the Y
capacitors and the isolation resistance.
Error Flags and Uncertainty
To navigate to the error ags window of the SIM100
GUI, click on the “Views” tab. On the drop-down
menu, select “Status”. Once “Status” has been se-
lected, the GUI will navigate to the Status screen.
The upper half of the status screen reports the esti-
mated value of the isolation resistance and isolation
capacitance of the negative and positive terminals of
the battery. Next to each value, the uncertainty of each
estimated value is reported; unit expressed in %.
In the case of high uncertainty, the uncertainty ag
will read “true” (see below for more information).
DC Voltage and Max DC Voltage on the screen refer to
the current value of battery voltage and the maximum
voltage observed since a SIM100 restart.
The bottom section of the status screen reports the
error ags. The error ags are reported as “True” or
“False”, indicating if the bit associated with the error
was set or not.
The reported error ags are:
Hardware Error: Detects error in the hardware of the
system. If the hardware error ag is triggered, inspec-
tion and appropriate actions should be taken.
No New Estimates: The no new estimates ag will
be triggered if the SIM100 was polled for new values
before the module has completed its calculations (can
take up to approx. 6 seconds). In this situation, the
values that are reported are the same estimates pro-
vided prior to the new request.
High Uncertainty: If the uncertainty of the reported
values is higher than 5% the high uncertainty ag will
be triggered.
High Battery Voltage: When the measured voltage of
the systems is higher than the maximum voltage saved
to the module, the high battery voltage ag will be
triggered.
Low Battery Voltage: When the measured voltage of
the system is below 15 V, the low battery voltage ag
will be triggered.
Hardware Errors
The hardware errors screen will show the various
potential errors in the hardware setup. The descrip-
tion of the various errors can be found in the SIM100
CAN2.0B Protocol documentation.
To navigate to the hardware errors screen, click on
the “Views” tab. On the drop-down menu select “HW
Errors”.
