Check the type of your PDT101 transmitters (voltage model / current model) before ordering new devices, as you cannot mix different types of PDT101 models in a cabinet installation. For more information, see Spare parts and accessories.

Follow the steps below to add new PDT101 transmitters to an existing set of transmitters in CAB100A. Note the different steps for 24 V DC and PoE powered models.

Refer to CAB100A layout diagrams when planning the installation.

  1. Switch off mains power.
  2. De-energize the existing PDT101 transmitters as shown below.
  3. De-energizing 24 V DC powered CAB100A model:

    Disconnect the PDT101 power wires from the fuse terminal blocks located at the right-hand end of the power block.

  4. De-energizing vNet PoE powered CAB100A model:

    Disconnect the Ethernet PoE cable from the vNet device.

  5. Mount the new PDT101 transmitter on the DIN rail.

    Rest the upper part of the locking mechanism on the DIN rail and push down firmly. This will click the device into place.

The PDT101 transmitters installed at the factory are connected so that the rightmost PDT101 on the DIN rail is connected to data logger channel 4. See the location of the data logger connector and channel markings next to it in 6 above.
