Telemetry Control Unit

DFS is an industry leader in providing pump controllers for thousands of pumping stations installed and operating nationwide. The Telemetry Control Unit (TCU), a SCADA ready pump controller, is designed specifically for level management applications such as Sewer Pump Stations, Lift Stations and Water Storage Tanks.

Preconfigured to operate up to three fixed speed pumps, and incorporating most of the required control components, the TCU is easily installed and placed into operation without the need for PLC programming knowledge. The TCU is also customizable for advanced VFD control.

The TCU combines powerful pump control functions with advanced SCADA communications, or an Autodialer, to provide a powerful, price-competitive solution. The TCU includes a 3-year lightning warranty.

Description

The Telemetry Control Unit (TCU) pump controller is a fully-programmable, dual-function device. The TCU can be factory-programmed to control up to three fixed speed pumps; or it can be custom programmed for a specialized control application.

As a pump control device, the TCU contains all the hardware and software needed to control up to three motor starters based on level input. Float ball switches, pressure transducers, or other types of analog level sensors are supported.

When used as a custom programmed device, the TCU can control up to six discrete devices, monitor up to 12 discrete inputs and monitor up to two analog devices.

The TCU features dual double-speed microcontrollers. One handles the control functions while the other manages the unit's communications. The TCU is available with an optional factory-integrated synthesized radio, network interface adapter, or a standard telephone line compatible autodialer.

An integrated AC phase monitor uses True RMS to produce accurate and exact 3-phase voltage readings. The analog inputs are 12-bit for superior accuracy and resolution. An auxiliary input function as a standard discrete input or pulse counter for a tipping bucket rain gauge. An RS-485 serial interface enables communication with industry-standard devices and VFD controllers. In addition, the unit features an RS-232 Serial Radio interface that supports both Modbus ASCII and Modbus RTU.

For ease of operator interface, the TCU incorporates a large 4x20-character LCD display and 12-button keypad. Eight LEDs surrounding the display are programmable for at-a-glace status indication.

Technical Specifications

LCD Display

The TCU features a large 4-line x 20-character LCD, and in conjunction with the 12-button keypad, provides an operator interface for configuring, analyzing status information, viewing and resetting alarms. The contrast of the LCD is controlled by an onboard temperature sensor, which ensures that the LCD screen is easy to read in both high and low temperature conditions.

Keypad

The TCU's 12-button keypad can be used to page through onboard menus items, scroll through configuration options, and enter numeric data. The keypad includes the 0-9, a decimal point, Enter, Escape, and scrolling keys. Several keys are dual functional and is dependent on the current mode. The unit features a power key, that when pressed and held cycled power on or off. The keypad is also used when IP address or phone numbers are required.

Service Port

The service port provides an RS-232 interface for diagnostics, configuration storage and updating. This service port allows a portable computer to be connected to the TCU through an interface cable. The configuration can be uploaded from the TCU and saved to a portable computer. If the TCU is replaced, the saved configuration can be downloaded from the portable computer to the new unit.

Warranty

Three (3) Year Return to Factory Warranty covering defective parts, workmanship and lightning damage .
