  • Empty DIN rail in the cabinet
  • The PDT101 transmitters you plan to install
  • PDT Wiring Set, 1 set per 4 PDT101 transmitters. The set contains the following:
    • Cable set for PDT or safety
    • Data logger data cable
    • Data logger holder
  • DL4000 data logger(s), 1 logger per 4 PDT101 transmitters
  • Small flat head screwdriver

For item codes, see Spare parts and accessories.

You can install only one type of device or measurement point (PDT101 transmitters, analog input channels, safety barriers, or galvanic isolators) per row in the cabinet.

In cabinet models with 5 to 8 data loggers, you need 2 serial port servers.

One serial port server controls the traffic of maximum 4 data loggers.

Make sure to number the data loggers as well as the cable sets and wires in the PDT Wiring Set before you install and connect them.
DL4000 data loggers are delivered with default factory settings. This applies both to the factory-installed data loggers and the ones delivered as spare parts. For instructions on configuring measurement units and scaling in the data loggers, see the Vaisala viewLinc Enterprise Server User Guide for your viewLinc version, available at www.vaisala.com/viewlinc.

Follow the steps below to install PDT101 transmitters as new devices to an empty DIN rail in CAB100B. Refer to CAB100B layout diagrams when planning the installation.

For instructions on expanding the number of PDT101 transmitters installed in the cabinet, see Expanding PDT101 transmitter installation in CAB100B.

  1. De-energize the cabinet: switch off mains power and the circuit breaker located inside the cabinet.

  2. Remove the cable duct cover below the PDT101 mounting location.
  3. Remove the long vertical cable duct cover in the middle of the cabinet.
  4. Mount the new PDT101 transmitters on the DIN rail, preferably at the left end of the rail.

    Rest the upper part of the PDT101 locking mechanism on the DIN rail and push down firmly. This will click the device into place.

  5. Assemble the data logger holder.
    1. Place the data logger in the logger holder.
    2. Fit the cover into place.
    3. Tighten the screw by hand.
  6. Connect the logger data cable to the RS-232 serial port in the data logger.

    Use a small flat head screwdriver to tighten the screw attached to the connector.

  7. Mount the data logger on the DIN rail, preferably at the right-hand end of the rail.

    Rest the logger holder locking mechanism on the DIN rail and push down firmly. This will click the device into place.

  8. Connect the logger data cable to a free port in the serial port server.
  9. Connect the PDT101 transmitters to the data logger and the power block as shown in 10 to 15.

    Use the cable set for PDT, which is included in PDT Wiring Set (Vaisala item code: ASM213079SP).

    The cable set for PDT contains wiring for 4 PDT101 transmitters. If you install only 1 to 3 PDT transmitters, leave the extra wires unconnected and the wire end caps in place.
  10. Remove the end caps from the wires in the cable set for PDT.
  11. Disconnect the screw terminal connector from the PDT101 by pulling it out.
  12. Observing polarity, connect the PDT101 wires to the screw terminal connector with a small flat head screwdriver.
  13. Follow the terminal block label markings on the PDT101 and plug the connector back in.
  14. Connect the data logger connector to the DL4000 data logger.
  15. Connect the power wire connector to the power block on the right-hand side of the cabinet.
  16. The new PDT101 transmitters are now mounted and connected.
