The MFC outputs the control signal to an invert-er for a certain stroke speed. The inverter con-trols frequency in accordance with the control signal to adjust the motor and pump speed.

The system has three main features. Stable stroke speed control down to 1spm. The MFC controls the stroke speed in the feed-back control by a stroke speed detector installed in the pump. This enables operation immune to the load fluctuation. Automatically controlled operation by the exter-nal input signal.

The MFC is designed for the reciprocating meter-ing pump (LK pump). The left picture is a wiring diagram.The devices required to compose the system are...• A MFC controller• A reciprocating metering pump

(With a stroke speed detector)• An inverter

7. Wiring7-1. Outline For proper operation, ensure correct wiring between the pump, inverter and stroke speed detector.

Installation

CAUTION

● Do not bind signal wires to a power cord or output relay wires together.● Do not share a power source with the high power equipment that generates surge

voltage, otherwise the controller may fail.● Risk of electrical shock. Be sure to provide a protective earthing.

Use a yellow/green spiral wire to secure correct wiring.● Use an isolator to extend the wire of the stroke speed detector. Reduction of signal

level and noise interference can cause malfunction.The sensor output is open collector.

● Refer to the instruction manual of the inverter for the wiring for inverter control and inverter RUN/STOP.

● Refer to the instruction manual of inverter for noise problems.

CAUTION● Wiring work while the pump is operating can cause electrical shock or short circuit. Be

sure to turn off power before conducting wiring work.● Right after power source is turned off, the internal circuit is still electrified. Wait one

minute or more before work.

Installation7-2. General wiring

1. Loose two screws with a driver to remove the ter-minal cover.

2. Remove an unused cord nut and a blind cap. And insert a cord into a terminal box through a cord nut and a cord gasket in order.

3. Connect the leads to the connector. Strip the end of the leads about 5mm and connect each lead into corresponding terminals. Tighten the screws on the connector to fix the end of leads with a flathead screwdriver by an approximate tighten-ing torque 0.4N·m.

CAUTIONConfirm that the connector is completely attached. Incomplete connection can cause a malfunction.

4. Attach the terminal cover and fix it with screws.

CAUTION

Mount the terminal cover while check-ing a terminal cover gasket is in place. Incomplete placement can cause a liquid influx.

5. Tighten cord nut in the last place.

CAUTION

4 - 8mm is the suitable cord diameter for wiring. When using the cord smaller than 4 mm, seal performance declines and this could lead to failure. Provide a preventa-tive measure.

7-5. Others Controlling the LK-M type pump by the MFC controller enables a wide range of the flow rate setting. In the operation at small flow rate, it takes long time for the pressure inside piping to rise depending on piping arrangement. Examine the piping arrangement including an importance of an air chamber.

9-2. Pulse dividing operationIn this mode, the pump runs in the dividing operation for the external pulse signal. Dividing ratio is variable within the setting range between "9999 : 1" and "1 : 1". The maximum stroke rate of the pulse dividing oper-ation is equivalent to that of manual operation. When the input signals are entered over the max stroke rate, the residual signals are stored up to 65535.

9-3. Pulse multiply operationIn this mode, the pump runs in the multiply operation between 1 and 9999 times for an external pulse signal and stops automatically. The stroke rate of the pulse multiply operation is equivalent to that of manual opera-tion. The incoming pulse signal during the multiply operation motions are cancelled and are stored up to 65535.
