VERY IMPORTANT This Kelco controller has been fully tested and calibrated. It is presently unlocked and has a simple program loaded. It is set to operate in a basic way with most of its special functions and features switched off.
All other functions are turned off. With the default program loaded, the F29 will start a pump in spite of an initial lack of flow, run the pump for 5 seconds and expect to establish flow past its paddle within this start up time.
5 second run-on time. This is the factory default setting for the F29 flow switch. All other functions will be turned off or set to zero. If you subsequently press the (P) button while the pump is running, the pump will stop and the LCD screen will display the Kelco splash screen and the controller’s model number.
After selecting yes or no to the remote input question and pressing (P) you are asked if you want to use the alarm relay. The F29 contains a dedicated relay (relay 2) with 16 Amp 240VAC rated voltage free contacts. The...

2) Closed if Flow Stops (Remains open if a fault develops) The second alarm choice means the alarm relay will close its contacts every time flow stops, unless there is a fault. This means stopping under normal circumstances. It means the alarm relay will not close its contacts if a fault occurs, as it would if you had made the previous choice.
This feature means the F29 will ignore entrained gas in the pipe system. The flow has to remain continuously off for whatever time you set on the run-on timer for the pump to stop.
F29. If your application only requires dry run protection for a pump and a start override to get the pump going in spite of an initial lack of flow then you will not require the advanced functions.
Each time the F29 is switched on it boots up but prevents the actual starting of the pump for the set period. As soon as the set time has elapsed the pump will start and run normally.
When using the batch control function with the remote input in start only mode the F29 also uses the remote input as a means of detecting dry run. In this scenario the remote input would ordinarily be connected to an external pressure switch.
In effect, zero stopping time means infinite stopping time as there is no defined set stop time. Set up this way the F29 will run for whatever time you have entered into the cyclic running run time and will then stop.
The F29 will sense no flow because the float valve will still be closed. The F29 will then shut down the pump and again wait for 12 hours before again attempting to start the pump. Using this technique prevents the pump from hunting on and off when the tank is full because of slight leakage from the float valve or pipework.
Single restart will attempt to restart the pump after a set time and if the attempt fails the F29 then shuts down the pump and goes into permanent alarm mode. It displays a “pump ran dry”...
The bore can be pumped until dry and the pump under the control of the F29 can be set to shut down as soon as loss of flow is detected and then wait until the standing water level in the bore recovers before attempting to restart and again pump the bore down.
F29 to tolerate in sequence. The default setting is 5. You can change this using the up and down buttons. The range of adjustment is 2 to 50 sequential starts. As a simple example of the way the anti-cycling system works, if the starts...

40 minutes. The pump will then be instantly shut down preserving whatever source water remains. The F29 will then display “burst pipe detected” on its LCD screen.
It will not operate in systems where the F29 is connected to tank level switches or other external devices. The leak detector will not appear in the F29’s main menu unless all other functions are turned off with...
The time that a pump runs for can be useful information to have. For example if a pump under the control of the F29 runs dry then it is useful to know how long it ran for before it ran dry. Consider an irrigation system where the F29 has detected a problem during a fixed irrigation cycle and shut the pump down.
The Hour Meter The F29 has a built in hour meter that keeps track of the total time a pump under its control runs for. The hour meter can be used for scheduling routine maintenance or for monitoring total water intermittently or continuously pumped over long periods.
