The Digital Tankmaster is a pressure controller which senses level of a tank and controls one or more pumps. The Digital Tankmaster consists of a Operator Interface Panel, a Programmable Logic Controller with digital and analog I/O, and a Pressure Transducer. The Tankmaster Operator Interface Panel has 4 function keys, 4 program arrows keys, and a enter key. The Operator selects pre-programmed screens and inputs level start and stop setpoints, time delays, alternation features, and alarm conditions. The Interface Panel has a Graphic Monochrome LCD display with a integral LED backlight. The display size is 3.2", with a pixel size of 128 by 64. One of the menu screens is the ELEVATED TANK STATUS. The status screen displays level in feet, plus a bar graph, and pump status. Other menu screens allow the operator to select level setpoints or time delays.

The Programmable Logic Controller has 2 analog inputs and 2 analog outputs, 14 digital inputs and 10 outputs. The PLC can expand to 136 I/O if required. The analog 4-20ma input is from a Pressure Transducer with a range of 0-50/100 PSIG. The Transducer can be mounted in the enclosure or remote from the panel. The Transducer has zero and span adjustments, with +/- .25% accuracy. Pump hand-off-auto control switches are provided for each pump. Pump output relays are provided and are rated 10 amp @ 120/230v. The Digital Tankmaster standard models are DT2A for 2 pump control, DT3A, and DT4A for 3 and 4 pump controllers. Master Level Controls will provide special programming for your application.
