The auxiliary voltages of power supply modules and the corresponding rated input
voltages of digital inputs are:
For further technical data of the power supply, refer to Table 5.2.1-2 on page 81.
5.1.5.2.
Low auxiliary voltage indication
The machine terminal is provided with a low auxiliary voltage indication feature.
The power supply module issues an internal alarm signal when a drop in the power
supply voltage is detected. The alarm signal is activated if the power supply voltage
falls about 10% below the lowest rated DC input voltage of the power supply
module, see the table below:
The indication of a low auxiliary voltage is available in the machine terminal
configuration environment and can be connected to any signal output of REM 54_.
The auxiliary voltage indication in the machine terminal configuration is as follows:
REM 543: PS1_4_ACFail
REM 545: PS1_4_ACFail
5.1.5.3.
Overtemperature indication
The machine terminal includes an internal temperature supervision function. The
power supply module issues an internal alarm signal when overtemperature has been
detected inside the terminal enclosure. The alarm signal will be activated once the
temperature inside the terminal enclosure increases to +78
o
C (+75...+83
o
C).
Overtemperature indication is available in the machine terminal configuration and
can be connected to any signal output of the terminal. The overtemperature
indication input in the machine terminal configuration is as follows:
REM 543: PS1_4_TempAlarm
REM 545: PS1_4_TempAlarm
