This guide covers all aspects of the PTU300 transmitter, starting with general information and product overview, followed by detailed installation procedures such as standard mounting, wall mounting, DIN‑rail, pole, and rain‑shield options. Wiring diagrams for power, signal, LAN, WLAN, and optional modules are included, along with instructions for configuring the serial and RS‑485 interfaces.
Operational sections describe how to use the display/keypad, set up language, adjust sensor heating, configure MODBUS, and perform calibration and adjustment for pressure, humidity, and temperature. Maintenance, troubleshooting, and technical data—including performance ranges and optional module specifications—are provided to support reliable field use.
The transmitter can be mounted using standard mounting without a plate, wall mounting kits, DIN‑rail kits, pole installation kits, rain‑shield kits, or a panel mounting frame.
The PTU300 supports LAN, WLAN, RS‑422/485, serial line, USB, and optional data logger modules for communication.
The language can be changed through the Display/Keypad menu under the 'Changing the Language' option.
