Tank Level Sensor..........................24 Line Pressure Sensor...........................25 Switched Outputs (pump control).......................25 Installation Safety Mains Voltage – There are exposed electrical conductors inside this appliance. This appliance must be installed and serviced by a competent electrical technician to the current requirements of BS7671 and IEEE recommendations. - Page 4 The control panel cannot be mounted outside, it is splash proof not weather resistant. Voltage drop will affect the cable size needed to take power to your pumps. Over very long runs, you may find it more economical to install contactors near to the pumps, allowing you to control the pumps with a sensible cable size.

Page 5: Control Panel Mounting
Control Panel Mounting If your control panel has been supplied with wall mounting brackets, these will attach to the rear of the panel and allow easy wall fixing without having to open the panel. If not then follow the instructions below. Having selected a suitable location, unlock the 4 locking screws on the corners of the front cover and withdraw the front panel. -
Page 6: Mains Power Connection
Mains Power Connection The power supply to the control panel enters via a cable gland on the bottom right of the housing. A 20A supply cable is provided with the panel. If you need to change this, insert the cable, connect to the incoming power terminal on the right of the PCB, and tighten the cable gland. -

Operation Safety Considerations Mains Voltage – There are exposed electrical conductors inside this appliance. This appliance must be installed and serviced by a competent electrical technician to the current requirements of BS7671 and IEEE recommendations. Before servicing this appliance, normal safe isolation procedures should be implemented. -

In the event of a power surge, fuses are ceramic with high (1250A) rupture current and MOV protection/track layout is designed to increase repair probability. PCB repairs are available and most component parts are stocked by 3P Technik UK. P Series v1.81 www.3ptechik.co.uk... -

Page 11: Initial Startup
Initial Startup Upon first applying power, The following screen will be displayed. Main Pumps Single Dual Press either button 1 or button 4 to select a single or dual pump configuration. The system now reboots. If no analogue level sensor is detected the system reconfigures to float switch mode and reboots. The LCD panel will display a startup logo followed by automatic calibration of the tank level sensor for approximately 3 seconds. -
Page 12: Tank Level Display
Tank Level Display The current supply tank level will be shown in %, and is measured by a submerged pressure sensor at the bottom of the tank. The scale is adjusted automatically as the control panel learns the maximum and minimum water levels within the tank, with 0% being the minimum level allowed (pump cut-off level) and 100% being the highest water level detected. -

Tank Menu (PF320) Supply Tank Menu Reset Set min Pump lvl ctrl Exit All options under this menu are related to operations within the water tank. Note - If an analogue level sensor is connected to PF120 the system will automatically re-configure to PF320 and reboot. -
Page 14: Pump Control (Pump Ctrl)
Pump Control (Pump Ctrl) This is a submenu containing functions related to pump selection and pressure. Providing 2 sub- menus as shown. Pump Control Menu Pressure Pumps Alarm Exit Pump Selection (Pumps) Here you can select which pump you would like to use. The default setting is Pump 1. If your system has 1 pump only then you should leave it on this setting. -
Page 15: Pump Pressure Adjustment
Pump Pressure Adjustment Here you can select a pump and alter its start and stop pressures. It is usual to set different start pressure for each pump and have them both stop when they reach the same upper pressure, but you can set them to start and stop at any pressure you want. -
