The West ProVu 4 Profiler with graphic/text LCD display is an affordable temperature and process controller with advanced functionality including profiling and datalogging options. Designed to improve user efficiency many features are integrated to reduce commissioning time, simplify operation and minimise maintenance downtime.

The LCD screen on the West ProVu 4 displays real-text messages, removing ambiguity that can be caused by mnemonic codes on LED displays used in many products. Information is displayed in a logical format to be easily understood, hence reducing the risk of errors. User screens are only displayed as each function is enabled, creating an optimised menu structure that is simpler to navigate. Access to specific settings and parameters can also be restricted by assigning them to password protected supervisor and configuration parameter access levels.

The process of configuring the West ProVu 4 is simplified as a setup wizard runs on first power-up. The user is guided step-by-step through the common parameter settings to quickly program the unit. These settings can be saved on a memory stick via the USB port and can be used for reconfiguration or to program other ProVU units. BlueControl software can be used for on and off-line configuration.

Flexible input and output option boards mean that the controller can be selected to precisely match an application. Universal process input (Thermocouple, PT100 & linear DC), digital inputs, remote setpointinputs, RS485 and Ethernet (Modbus TCP) comms and up to nine outputs (relay, SSR driver, triac, linear DC and 24V transmitter PSU) are all available .

The optional profiling function on the West ProVu 4 supports 255 segments for use in up to 64 profiles, segments supported are ramp, dwell, hold, loop, jump to profile. Profile control is possible from the controller, remote input or timed via the integral real time clock.

There is an increasing requirement to log process data for quality control purposes. The optional datalogging feature is a low cost method of recording historical data for exporting to a .CSV file.
