Power supply, coding switches 3.2. Power supply 3.2.1. Internal power supply Every slot card installed in the PC is automatically supplied via the PC power supply unit when you switch the PC on. Power is supplied via the ISA interface. The different models are supplied from various sources: -- PC Control 645-12M (645.425.01): Voltage / power consumption: 5 V DC / c. 0.4 A -- PC Control 645-12M NT (645.425.10): Voltage / power consumption: 12 V DC / c. 0.15 A 3.2.2. External power supply Applies to PC Control 645-12M NT (645.425.10) only. This model supports both methods, internal (see above) and external power supply: -- Voltage: 24 V DC -20%+25% -- Power consumption: c. 0.15 A -- Connector: 2-pin screw-type locking connector +24 V DC 0V The external supply ensures that the card can also be operative when the PC is off which adds to the security of the process controlled. Install the card in the PC before you connect it to the external power supply. Never start it outside the PC. Failure to comply with this rule may lead to card damages. 3 - 2
Hardware 3.2.2.1. Uninterrupted switchover If the external power supply fails, the PC automatically immediately takes over without any interruption - if it is on. The integrated undervoltage monitoring detects voltage dips in good time. The monitoring function is enabled when the card is exclusively supplied externally (PC off). You can provide for the appropriate action via the user program to ensure a safe status in case of a failure (see chapter "4.10. Error and failure handling"). 3.2.2.2. Potential separation 3.3. Reset button The connection to the external power supply has no potential separation. Thus, the "0 V" line is internally connected to earth via the PC. You must therefore make sure either -- to provide a non-potential external supply, i.e. one that is not connected to earth or -- to provide an equalisation of the potential between the earth connection of the external supply voltage and the PC's earth connection. Connecting the external power supply to earth without equalising the potentials may lead to the occurrence of equalisation currents that may destroy the card or the PC or some of their components. Press the red Reset button to reset the card (see chapter "3.4.2. Reset"). The card will restart when you let go of the button. 3 - 3

3.2.2.1. Uninterrupted switchover<br />
If the external power supply fails, the <strong>PC</strong> automatically immediately<br />
takes over without any interruption - if it is on.<br />
The integrated undervoltage monitoring detects voltage<br />
dips in good time. The monitoring function is enabled when<br />
the card is exclusively supplied externally (<strong>PC</strong> off). You can<br />
provide for the appropriate action via the user program to<br />
ensure a safe status in case of a failure (see chapter "4.10.<br />
Error and failure handling").<br />
3.2.2.2. Potential separation<br />
3.3. Reset button<br />
The connection to the external power supply has no potential<br />
separation. Thus, the "0 V" line is internally connected<br />
to earth via the <strong>PC</strong>.<br />
You must therefore make sure<br />
either<br />
-- to provide a non-potential external supply, i.e. one that is<br />
not connected to earth<br />
or<br />
-- to provide an equalisation of the potential between the<br />
earth connection of the external supply voltage and the<br />
<strong>PC</strong>'s earth connection.<br />
Connecting the external power supply to earth without<br />
equalising the potentials may lead to the occurrence of<br />
equalisation currents that may destroy the card or the <strong>PC</strong> or<br />
some of their components.<br />
Press the red Reset button to reset the card (see chapter<br />
"3.4.2. Reset").<br />
The card will restart when you let go of the button.<br />
