1 and it has it’s startup and run-on timers both set to 10 seconds. All other functions are turned off or set to zero. Provided the F60 is unlocked you can restore it to this default state at any time by pressing and holding down the (P) button and pressing the (R) reset button at the same time.
Introduction The F60 pump controller includes a set of functions that can be set up to control a pump. The functions range from a simple override on start timer that allows a pump to start in spite of an initial lack of flow, through to sophisticated cyclic running and stopping sequences.
The Three Operating Modes The F60 can be set to operate in one of 3 fundamental operating modes. An initial choice must be made as to how you want to control the pump. Once you have made your choice, the F60’s menu will ask you a series of questions that relate to...

Pump control is solely based on flow and time. The controller’s pressure sensor is used to display the system’s dynamic pressure on its LCD screen during normal operation. F60 Modes & Functions MODE 1 Functions (# Settable) # Select pressure units kPa or psi...

Mode 2 Flow Control In this mode the F60 will start the pump each time the pressure falls below a preset value or whenever the controller’s paddle is pushed to the on position by flow. It will then run the pump entirely on flow. Unlike a conventional pressure...
Pressure System Operation If operated in mode 3 the F60 will only start the pump on flow on a rising pressure. Consider a standard pressure system operated through a pressure switch. The pump will start each time the pressure switch closes its contacts and stop each time the pressure switch opens its contacts.
The F60’s ability to operate on a close differential can be a major advantage in certain circumstances. In theory the cut-out pressure of the F60 can be set to 1kPa higher than the cut-in pressure. With such a setting the controller will operate on a differential of 1kPa.
For example, some VS drives require a few seconds to stabilise and the F60’s pre-run timer can hold off the starting of the pump until the whole system has stabilised. The pre-start timer can also be used to stage or stagger the starting of multiple pumps.
The snore time can be set to any value from 0 to 240 seconds (0 to 4 minutes) in increments of 1 second. The F60 identifies a dry run situation when the paddle has remained in the off position for longer than the time you have set on the snore timer.
(perhaps a few seconds). The F60 will sense no flow because the float valve will still be closed. The F60 will then shut down the pump and again wait for 12 hours before again attempting to start...
If a set running and stopping time are programmed in, the F60 will run the pump for whatever time it is set to and then stop for the time set on its stop timer. If a run time is set to some value and the stop time is left set at zero, the pump controller will behave as a one-shot batch controller.
2 and 3. If the F60 is set to operate in mode 2 or 3 it will identify any dry run situation that may occur and respond by shutting the pump down, thus preventing damage to the pump.
Such rapid cycling will cause the pump to overheat very quickly. The F60’s anti cycling feature can be used to shut down the pump and prevent damage in such a situation. To use the anti-cycling function for this type of pump protection simply set the starts per hour to some value that is marginally higher than the system’s normal start rate.
Burst Pipe Detector The F60 includes a unique system for detecting burst pipes. The burst pipe detection system can be used in all modes. It is most commonly used in pressure systems. If a pressure system bursts its discharge pipe the system pressure will fall and the pump will start at its low pressure setting.
Leak Detector The F60 includes a unique leak detection system that can be used as a tool to analyse suspected leakage in a pressurised pumping system. The leak detector only operates in mode 3. It can be switched on or off in the main menu. It should be left switched off when not required as its display screen excludes the display of normal system pressure and messages when it is in use.
When locked, pressing the (P) button has no effect on the F60 and does not take you into the menu in the usual way. Access to the menu can then only be obtained by first unlocking the (P) key.
