Connection of sensors

Up to four of the following CMC sensors may be connected to the PDU:
– Temperature sensor (7030.110)
– Temperature/humidity sensor (7030.111)
– Infrared access sensor (7030.120)
– Vandalism sensor (7030.130)
Connect one of the above sensors from the accessories range to the CAN bus interface of the PDU
using a CAN bus connection cable (fig. 11, item 2).
Status change display:
– The two green and the two red CAN bus LEDs on the CAN bus connection of the connected sen-
sor will start to flash.
– The multi-LED of the PDU flashes continually in the sequence green – orange – red.
– The multi-LED of the connected sensor flashes blue continuously.
Confirm the newly connected sensor on the PDU website.
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 PDU:
– 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 connected sensor.
– Continuous blue flashing: Communication via the CAN bus.
– Green flashing: When the measured value changes or, at the latest, every 5 seconds.
Further sensors are connected as daisy chain.
If necessary, connect another component (e.g. another sensor type) to the second, free CAN bus
interface of the first component.
Proceed in the same way for further components (up to four units in total).
Note:
Further information concerning the connection and configuration of sensors can be found
in the associated documentation of the accessory part.
