F30 12V DC WIRING DIAGRAM

The F27 and F30 controllers require a continuous stable supply
to their Active terminals. In most installations they will also need
an isolation switch to allow them to be reset. To protect the
controllers a 125mA fast blowing fuse should be placed in series
with the supply active. All controllers are protected from over
voltage by high amperage varistors that will blow the control
circuit fuse in the event of a voltage surge beyond the maximum
limits set out in the table below. Where possible ensure the
control circuit is not on the same phase as the pump motor. This
is particularly important where long cable runs are involved.
Voltage drop from the pump motor starting may cause the
controller to reset, or its output relay to chatter and cause the
pump to jog. Jogging can snap a pump shaft very quickly, so
please take all precautions to ensure the supply to the controller
is stable and adequate for the job.

Supply voltage must be

within the limits set out in the table below.

Note:

Current draw with their internal relay energised is
<85mA for all F27 and F30 controllers.

All the controllers use an inbuilt relay as their output. The
contacts of the relay are voltage free. The relay contacts are
rated at 250VAC at 10Amps resistive. To ensure a long
reliable life from the controllers we recommend all pump
motor control should be via a suitable contactor.

The F30 controllers require an input from an external
pressure switch located in the discharge pipework of the
pump. The F30 accepts a switched input to its AUX terminal
that is at the same voltage, and derived from the same phase
as the main supply to the F30. The current draw through the
pressure switch is <5mA. Series connect the pressure switch
contacts between the control circuit active and the AUX
terminal.

Use only the contacts that close on a falling

pressure, that is, the low-pressure cut in contacts.

If the

switch has duel poles, connect both sets of contacts in
parallel to reduce the resistance path through the switch.
Details on setting up and adjusting the pressure switch can be
found further on.

ONLY ON THE F30, THIS LIGHT TURNS
ON WHENEVER THE PRESSURE SWITCH
CONTACTS CLOSE.

THIS LIGHT TURNS GREEN WHEN THE START-UP
TIMER IS RUNNING AND TURNS RED WHEN THE 
RUN-ON TIMER IS RUNNING

THE START-UP TIMER IS ADJUSTABLE FROM 1 SECOND TO 
3 MINUTES AND IS USED TO GET THE PUMP STARTED IN
SPITE OF NO FLOW.

THIS LIGHT INDICATES THE TRUE POSITION OF THE PADDLE.
IT TURNS GREEN WHENEVER THE PADDLE IS ON.  ON THE F30
IT ALSO FLASHES RAPIDLY RED TO INDICATE IF THE PUMP 
HAS RUN DRY.

RUN-ON TIMER
THE RUN-ON TIMER SETS HOW LONG THE PUMP RUNS ON 
AFTER FLOW STOPS.  ON THE F30 IT ALSO SETS HOW LONG
THE PUMP RUNS AFTER THE PRESSURE SWITCH CLOSES.
IT IS ADJUSTABLE FROM 1 SECOND TO 5 MINUTES.

IT BLINKS SLOWLY RED IN STANDBY MODE

WHENEVER THE POWER IS ON.

Red

Indicates that the paddle is in the on position.
Normally off, this light turns green as soon as flow
pushes the paddle into the on position.  The pump
will be on whenever this light is green

Blinks every two seconds to indicate power is on to
the controller.  This light will slowly blink red
whenever the power is on but the pump is off.

On the F30 controllers only, this light flashes rapidly
red indicating that the pump has run dry and the
controller has shut down the pump due to lack of
pressure.  Normally the blue auxiliary light will also
be on, indicating that the pressure is too low. 

Green

Red

Provided the start-up timer is set to some value
other than zero, this light Indicates that the start-up
timer is running, only comes on when the controller
is first powered up.  The pump will run while ever
this light is on.

Indicates that the run-on timer is running.  Can only
come on after the start-up timer has timed out.
Provided the run-on timer is set to some value
other than zero, this light will switch on whenever
the paddle swings to the off position.  On an F30
controller it will also switch on whenever the
pressure switch contacts close.  The pump should
be running while ever this light is on.

Blue

This light indicates the true status of the remote
pressure switch.  It is on when ever the contacts of
the pressure switch are closed.  The pressure
switch contacts must be open and this light off
before the run-on timer times out.  If not, the
controller will shut down the pump and go into
alarm mode and the red paddle light will flash
rapidly.  The pump will not restart until power to the
F30 is reset.
