The WP-3000 Series Digital Indicators are advanced instruments designed for precise measurement and display in various industrial applications. These devices offer a comprehensive set of functions, including input scaling, sensor compensation, alarm capabilities, and communication interfaces, making them versatile tools for monitoring and control.
The core function of the WP-3000 Series is to accurately measure and display various input signals. It supports mA input (DC 4.00~20.00mA) and pulse input, allowing it to interface with a wide range of sensors and transducers. The device features a display scaling function, which enables users to adjust the displayed value according to specific scales and input ranges. This is particularly useful for converting raw sensor data into meaningful engineering units, such as t/m (tons per minute) for flow rates. For example, an input range of 0.00~10.00Hz can be scaled to display 0.00~7.00 t/m, providing a direct and intuitive reading for operators.
Another key function is the output scaling, which allows the 4.00~20.00mA output value to be scaled to a desired output range. This is crucial for integrating the indicator into control systems, where the output signal needs to correspond to a specific process variable.
The sensor compensation function is designed to correct errors that may arise from long sensor lines or changes in the sensor's zero point due to aging. This ensures the accuracy and reliability of measurements over time, reducing the need for frequent recalibration. For instance, if a sensor initially reads 10.1 t/h and requires a -0.1 compensation, the device can be configured to display the corrected value of 10.0 t/h.
The WP-3000 Series also incorporates a "Function (mA type)" feature, which includes options like F-SL (pass input as is for general input and linearity) and ROOT (pass input after square root calculation, used for flow rate by orifice). This flexibility allows the indicator to adapt to different measurement principles and signal processing requirements. Additionally, a "LIMIT" function is available for applications like level measuring, ensuring that the display always shows zero when the measured value falls below zero.
Alarm functions are integral to the WP-3000 Series, providing critical alerts when process variables exceed or fall below predefined thresholds. The device supports high and low alarms with configurable dead bands. For example, a high alarm (AL-1) can be set to activate when the present value (PV) reaches 500.0 or more and deactivate when it drops to 499.5 or less. This hysteresis prevents rapid toggling of the alarm when the PV fluctuates around the setpoint.
An optional POT (Pulse Output) function is available, allowing the device to generate pulse outputs based on the input signal. This can be configured for pulse per hour (e.g., 3600 pulses per hour at 20mA input) or pulse per second (e.g., 20 pulses per second for a given high scale value).
The communication interface, specifically RS-485, enables the WP-3000 Series to communicate with computers and facilitate remote monitoring. This feature is essential for integrating the indicators into larger supervisory control and data acquisition (SCADA) systems.
The WP-3000 Series is designed for ease of use and robust operation. The front panel includes a clear measured value display, alarm condition indicators, and intuitive buttons for operation and setting. The "MODE" button is used to memorize setting data and navigate through operation menus, while the "EXIT" button allows users to exit modes and return to the PV value display. Data setting involves a straightforward process of selecting the decimal point, flickering the desired digit, and adjusting the value using the navigation buttons.
The device offers a selection of moving average filters (None, Average 4, 8, 16, 32) to stabilize the display and output values when the input is irregular. However, it is noted that using a filter may delay response, so it should be used judiciously, especially when high-speed response is critical.
For initial setup or in cases where all parameters need to be reset, the device can be initialized by simultaneously pressing the "MODE" and "EXIT" keys while turning on the power. This restores the instrument to its factory default settings.
Installation is straightforward, with recommendations for panel thickness (1.2mm to 5mm) to ensure secure mounting. The terminal diagram provides clear guidance for wiring power sources, input signals, and output connections. The device also includes a built-in sensor power source (DC 12V 30mA ±0.5%), simplifying wiring for certain sensors.
Maintenance of the WP-3000 Series emphasizes safety and proper handling. Users are explicitly warned to disconnect the instrument from the main power source before any wiring to prevent electric shock. Protective grounding is mandatory before turning on the instrument, and the protective grounding conductor should never be cut. The device should only be operated within specified environmental conditions, avoiding exposure to combustible, explosive, corrosive gases, water, or steam.
For cleaning, only a dry cloth should be used on the instrument's surface, and organic solvents should be avoided. Cleaning should always be performed after turning off the power.
The manual stresses that only authorized service personnel from Wintech Process Co. are permitted to remove or disassemble internal components such as the inner module, main unit, or printed circuit boards. This ensures that repairs and maintenance are performed correctly and safely, preserving the integrity of the instrument.
In terms of disposal, used products should be disposed of properly, and incineration of plastic maintenance parts or replacement parts is prohibited due to the potential production of harmful gases. Instead, the instrument should be consigned to a special agent for industrial waste disposal.
The instruction manual itself is a crucial maintenance feature, providing detailed guidance for operation, setting, and troubleshooting. Users are advised to read the manual thoroughly before handling the instrument and to keep it carefully for future reference. In case of loss or damage to the manual, a replacement can be obtained from the sales representative.
