Installation and operation of the slave PDU managed, Technical specifications
7.3
Connection to a CMC III processing unit
Connect the PDU to the CMC III PU or to the adjacent components in the CAN bus using a CAN bus
connection cable (fig. 16, items 1, 2).
Status change display:
– The two green and the two red CAN bus LEDs on the CAN bus connection of the PDU will start
to flash.
– The multi-LED of the processing unit flashes continually in the sequence green – orange – red.
– The multi-LED of the PDU flashes blue continuously.
Press the "C" key on the CMC III PU (an initial audio signal will sound) and keep it pressed for approx.
3 seconds until a second audio signal is heard.
Status change display on the CAN bus LEDs:
– Continuous green LEDs: CAN bus status "OK".
– Continuous red LEDs: CAN bus status faulty.
Status change display on the multi-LED of the processing unit.
– Continuous green light: All devices connected to the CAN bus have the status "OK".
– Continuous orange light: At least one device connected to the CAN bus has the status "Warning".
– Continuous red light: At least one device connected to the CAN bus has the status "Alarm".
Status change display on the multi-LED of the PDU:
– Continuous blue flashing: Communication via the CAN bus.
– Green flashing: When the measured value changes or, at the latest, every 5 seconds.
– Continuous orange flashing: The PDU has "warning" status. Fast flashing: upper limit value over-
shot. Slow flashing: lower limit value undershot.
– Continuous red flashing: The PDU has "alarm" status. Fast flashing: upper limit value overshot.
Slow flashing: lower limit value undershot.
– Continuous red light: Invalid measured value.
Note:
Connection cables in various lengths can be purchased from Rittal.
If installation was unsuccessful: see section 1.1.
