The TCU800 pump controller automates the management of simplex, duplex, and triplex sewer pumping stations. Building upon the successful TCU001 pump controller, which is in use in tens of thousands of pumping stations across the US, the TCU800 boasts a 5” touchscreen interface for operators, enhanced processing speed, and expanded on-board inputs to bolster monitoring and motor protection functionalities. The base programming is designed for fixed-speed or soft-start motor controllers. However, the TCU800 has expanded capabilities where Variable Frequency Drives (VFD) can be controlled and monitored using user-selectable modes of operation with an external Modbus I/O device.


Optimal Data Usage

The TCU800 is equipped with all necessary hardware and software to control pump operations based on level input from floats and/or analog level-indicating transducers. An integrated True RMS AC phase monitor provides accurate three-phase voltage readings and under/overvoltage motor protection. It also can give motor current readings (with optional CTs) with specialized user-selectable display options for optimal data usage.

SCADA-ready with open Modbus RTU and ASCII protocols, the TCU800 is available with optional factory integrated TAC II radio, network interface, and/or Verizon cellular modem. The TCU800 introduces additional on-board monitoring of motor seal fail and high-temperature contacts for motors so equipped. These additional inputs are user-programmable to be used by the TCU800 to remove a motor from service, simply create an alarm, or used as additional discrete inputs. Its integrated HOA switches ensure fail-safe operation, functioning even when the TCU800 is unpowered. The touchscreen Graphical User Interface (GUI) offers intuitive access to operation menus, set-point adjustments, fault resets, and status indications with a simple touch. Additionally, ultra-bright LEDs offer instant feedback on pump, power, and alarm status, as well as active communication usage.
