5.2. Measuring other CGU 04i signals
5.2.1 Measuring the supply voltage
Another two signals are measured in CGU 04i. The first is called +UN (DC SUPLY), it
is an internal one and describes supply voltage on CGU 04i brackets. The measuring range is
0 to 30 V. The supply voltage value has an effect over CGU 04i function – in case it falls below
the set value the GSM module is disconnected, because its proper function is not
safeguarded, and discharge current of reserve accumulator is reduced.
The second one is INAC (AC SUPLY) linked to the supply connector (see the supply
connector description). The measuring range is 0 to 30 V. The signal is protected against
overvoltage by a protection element that blocks voltage in excess of 16 V. INAC is designed
for measuring of network supply voltage presence. The change of the value is recorded in
CGU 04i statistics as a failure and rise of supply voltage 230 V.
Beware – it is impossible to link 230 v supply voltage directly to the input!

5.2.2 Measuring internal CGU 04i temperature
To ascertain proper GSM module function, temperature is measured inside CGU 04i. In
case the temperature exceeds the set control value, the GSM module is disconnected from the
supply voltage, as proper function is not guaranteed over this temperature and at the same
time it is protected against heat damage.
