Turbo and Active Gauge (TAG) Controller Edwards TAG (Turbo & Active Gauge) controller is a small low cost pumping system controller, suitable for a wide range of vacuum applications and compatible with all Edwards EXT and nEXT turbopumps. The large LED display shows the pump speed or vacuum pressure and an easy to use push button interface enables ease of operation and control. TAG controller will also run a backing pump, air vent valve an air cooler and an Edwards active gauge, making the TAG a versatile system controller. This compact 24V TAG controller is ideal for use on bench-tops or suitable for mobile platforms where space is limited yet functionality and reliability are essential. NOTE: TAG controller does not contain an in-built power source. A 24V power supply is available from Edwards or users must supply their own. Features and Benefits Turbopump control capabilities —— Turbopump start/stop —— Display pump speed as % of full speed —— Visual performance display; acceleration, deceleration or normal running —— Control of a single vent valve when connected to the turbopump controller with choice of three vent modes ◦ Vent when pumping speed drops below 50% ◦ Controlled vent from full speed then hard vent at 50% ◦ Fan mode, continuous power to the vent port so the system will not vent. Alternatively it may be used to power an air cooler connected directly to the pump Gauge control and display functions —— Control of a single Active gauge: APG, AIM, ASG or WRG gauge —— Choice of pressure display: mbar, Torr, Pascal or Volts —— Zero adjustment/calibration of gauges —— Use of gauge signal to start/stop the turbopump Backing pump control, plus more —— TAG has the additional capability to control a backing pump —— 24V EXT/XDD1 may be connected directly and will share power with TAG/turbopump —— nXDS and XDS35i pumps can be controlled by the TAG logic interface —— Other mains backing pumps may need a relay (see instruction manual for details) —— A single 24V isolation valve can be controlled and powered from the TAG —— For pumping large chambers the TAG allows delayed start of the turbopump to either a time or pressure set point
