TC340 Tank Controller - 4 outputs
Automatic Water Level Control
The 3P TC Series Tank Controller maintains and monitors the level of water in a storage tank. A precise level sensing probe detects the exact height of water present in the tank. The Controller then uses any of four mains voltage outputs which can be connected to pumps, solenoids, motorised valves or any other type of filling or draining device to maintain the level between defined limits.
Each pump or valve connected to the Controller is assigned high and low switch levels, and is set as either a drain or fill function. A pump supplying water to the tank would be a fill device, one in the tank itself would be an drain device.
In a drainage application, 2 pumps could be set in a chamber, assigned as drain type devices and set to start at different levels to produce a duty assist/standby pump chamber.
For a water storage application, a pump or solenoid could be set as a fill device, supplying the tank with water. A second output could then be used to manage an automatic pump supplying water from the tank with dry run protection and both devices operating from the same sensor.
To provide more complex functions, each output can be linked to any of 5 switch inputs, which must be closed for the output to operate. This is in addition to the minimum and maximum levels that the output must operate within and is useful in cases where water is to be transferred from point to point. Filling a tanker for example could be conditional on sufficient water in the main supply tank, and also depend on a shut-off or level switch on the tanker or filling hose. Alternatively a pumped stormwater attenuation system could be linked to a rain sensor to stop emptying the tank when rainfall is detected.
Level sensing is achieved via a single pressure sensor installed on the base of the tank. This reads the actual water depth and the Control Panel then shows the exact level and operates accordingly, thereby removing the reliability issues associated with float switch based systems.
The use of a single level sensor also allows for the stop and start levels to be adjusted from the control panel. There is no need to enter the tank to fit and adjust float switches, and no uncertainty as to whether a pump is operating at the correct water levels. The number of cables required for level control is also reduced to 1 per tank.
Multiple devices can be operated within the same tank, or a second level sensor can be added, giving a single panel control over 2 tanks at the same time. Both tanks could be part of a connected system, totally separate systems, or separate systems sharing the same switch inputs. Finally both sensors could be used within the same tank to provide duplication of sensors and/or pumps/valves as a safeguard against component failure.
Available with 2, 3 or 4 outputs, each output can be configured as a Drain or a Fill function depending on whether the attached device takes water to or from the tank when powered.
High and low level alarms are also set from the control panel, and a switched BMS output (volt free contact) is provided, which can be also used to activate sirens/strobes
All TC Series systems have intuitive menu driven settings. There are no hidden menus, and almost everything is adjustable, level probes are automatically detected when plugged in, and no level calibration is required.
3P TC Series Tank Controllers also incorporate Advanced Fault Tracking. Fault codes are stored in memory until you choose to erase them, allowing easy identification of intermittent and historical faults.
Clever design of the circuit board makes the TC Series the most robust unit on the market today, with overvoltage and brownout protection, immediate recovery from power failures with no loss of setting and auto reboot, individually fused outputs, oversized power supply to electronics, removable MCU chip (software) for easy upgrades. Modular connector design and tolerant software allows pumps and sensors to be ‘hot-swapped’ without switching off the controller or remaining pump.
