monitor input logic contacts P_WD and S_WD, The basic philosophy is that master RU monitor the
signal coming from primary and secondary IDA8C/8Ss to decide which one can be active, and also
pass the decision to next RU through EXP_OUT port. The judgment logic is different between
IDA8RU set to master and slave.

Ateis Net

Each IDA8C and IDA8S connect with its own Local Ateis Net. If one of the system is out of order,
another one will replace .

24V DC Power Supply

From IDA8 to RU-MAIN:

IDA8: 24VDC output.

RU MAIN: Power Supply 24VDC/0.25A.

From RU-MAIN to RU-PDC/CTL:

RU-MAIN: Expansion Power Supply.

RU-PDC/CTL: Power Supply 24VDC/0.25A.

Note:

The only power supply for RU is from IDA8s. In case the 24VDC output connector and wire are not
working right, IDA8 can detect it and show the info on the TFT screen.

If there is no power supply in the system, it means both the IDA8Cs are out of order, please contact
your Ateis dealer.
