3, 3 In order to wire the wireless units, it is necessary to unscrew their covers and remove their electronics modules. Screw terminals are located on the reverse side of the electronics modules. Wires should be run through the conduit entry holes at the rear of the device en- closures. The following diagram shows screw terminal locations on the electronics module. Basic Wiring of Wireless Units Analog Input Wiring The analog input may be either 4-20 mA, 0-10 V, 0-5 V, or 1-5 V. The appropriate input type must be programmed for ea…

4, 4 The diagram below shows a typical PDW30 installation. A transmitter is outputting an ana- log signal to the primary wireless unit. The analog signal is being wirelessly broadcasted to the secondary unit which then sends a 4-20 mA signal to the destination device. This guide will show you how to congure this type of installation. Wireless Installation Any wireless network can be negatively a󰀨ected by certain factors, such as physical obstacles and improper equipment placement. Please review the wireless installation tips b…

5, 5 The primary wireless unit determines network protocol and digital I/O settings for the sec- ondary unit, simplifying the setup process. If a digital connection is programmed to be an input on the primary unit, that same connection will be an output on the secondary unit. Primary Device Setup • Press to access the device menu. • Press to access the ANALOG INPUT menu. • If the desired input type is not 4-20 mA, press . Press to select the desired input type and press . • Press so the display reads…

6, 6 Both the primary and secondary wireless units may be protected with a four digit numeric password in order to prevent unauthorized tampering. When a password has been set, you will be prompted to enter that password in order to access the device menu. Setting a Password If a mistake has been made while programming either the primary or secondary device, and it is unclear where the error occurred, the best option may be to perform a factory rese…
