LogicFlow & LogicPress

Logicpress features: 

Automatic reset function: pump protection from dry running but with automatic reset, enabling the pump to operate normally again during a condition where the lack of water may have only been temporary. In this situation, a conventional pressure controller would switch off and the system would require a manual reset, which could cause inconvenience. Both devices are designed to make 10 attempts to start over a 24 hour period. On the 10th attempt, if the condition still exists i.e. it is not temporary, it switches off. A system inspection and manual reset is then required. 

Daily pump test function: if for any reason the pump remains idle for 24 consecutive hours, both devices are designed to start up the pump for about 5 seconds. This helps to avoid various problems associated with pumps inactive for long periods. 

Dual voltage: It can be operated at 110 volts or 230 volts and with 400 volts 3 phase (with a contactor). 

Application conditions are: 

The column of water between the switch and the highest outlet must not exceed 15 metres (1.5bar) – the “restart pressure value setting” - otherwise the system pressure may not fall to the pre-set “cut in” pressure and the system will not restart. This value is pre-set at factory, so no additional programming is required, or possible, during installation. 

Minimum flow required inwards is 1 litre per minute. 

It must be operated vertically. 

Logicpress(M): this is the same product as the Logicpress, but with a factory fitted Manometer pressure gauge (M). 

Logicpress SET: this is the same as the Logicpress but with three pre-programmed restart pressure settings of 1.5, 2.0 and 2.5 bar, which can be programmed by the user. This feature enables the user to purchase one device for a range of duties. It must be operated vertically. Minimum flow required inwards is 1 litre per minute. Optional pressure gauge (M). 230v only, or 400v (with a contactor) 

Logicpress SET (M): this is the same product as the Logicpress(M), but with a factory fitted Manometer pressure gauge (M). 

Logicpress PLUS: this has the same features as the Logicpress, but is for higher flow rates and hence has a larger inlet and outlet. 

Logicpress 3PHASE PLUS: this has the same features as the Logicpress, but is specifically for 3 phase pumps (230v and 400v) that have higher flow rates and hence has a larger inlet and outlet. It has reverse rotation protection. 

Logicflow: for surface mounted pumps only in applications of positive suction i.e. underneath a tank or direct withdrawal from the mains water supply. It will start a pump immediately when a valve in the pipe system is opened and stop the pump immediately when the valve is closed. It has integral dry running protection an external re-set switch, pump status LEDs, power black-out auto reset, dual voltage (110- 230v) and has IP65 protection. Minimum flow required inwards is 0.5 litres per minute. 

Manometer: this is a pressure gauge that can be retro-fitted to Logicpress and Logicpress SET. Models with this device, factory fitted, have suffix “(M)”
