(1) Pump operation:

① When proximity switch R input is on, solenoid valve operation output keeps ON condition.

② Even if proximity switch R input is off, solenoid valve operation output keeps ON condition.

③ At the condition of proximity switch L input is on, solenoid valve operation output becomes off.

④ Then, until proximity switch R input comes on, solenoid valve operation output keeps off condition.

⑤ The above operations (①~④) shall be repeated in order.

(2) Flow rate control:

1 shot flow rate for F pump has been arranged; discharge capacity shall be “pump stroke rate times 1 shot flow rate”.

When the flow rate was set arbitrarily, stroke rate shall be converted automatically within the controller. Comparing

this converted stroke rate and operating cycle of proximity switch, which is effected to input into controller while

pump is operating, control voltage (DC0~10V) to Electro-pneumatic regulator (ER1) shall be adjusted. Varying

secondary air pressure of electro-pneumatic regulator (ER1), discharge capacity shall be controlled.

(3) Leak alarm:

This function effects to stop pump with alarm signal when pump brings about leakage.

It detects leakage and makes output signal by that leaked liquid conducts between electrodes (C1- C2 or D1-D2) of

which set up corresponding to each bellows (left and right).

Receiving this alarm, the controller effects warning, and put control signal off to Electro-pneumatic regulator

simultaneously. Then, it makes stop pump.

On this occasion, pneumatic pressure to drive inside of pump shall be released and becomes no-pressure only when

Electro-pneumatic regulator (optional) is being used.

(4) Time up alarm:

This function effect to alarm when pump stops or stroke speed becomes abnormally slow down for some reason.

Output for solenoid valve still keeps operating condition, though. Time set for criterion of warning shall be

executed on setting screen No.8.

It makes output as an alarm in case of whatever longer stroke time (t1, t2 and t3), than preset time t0. When all of

t1, t2 and t3 become shorter than t0, this alarm shall be reset automatically, and starts operation again.

(5) Life alarm:

This function effects to alarm and notice when accumulated count number becomes beyond the fixed total count

number which was set manually.

Output for solenoid valve and Electro-pneumatic regulator (optional) still keep operating condition, though.

Total count number setting can be executed at setting screen No.9, and also, it is able to reset by manual reset or

reset signal from the externals. After input of reset, Life alarm detection is neglected for 2 minutes. After 2 minutes

past, it detects again if pump is operating condition.

(6) Fast alarm:

This function effects to alarm when pump stroke became abnormally faster than the preset stroke rate for some

reasons. Output for solenoid valve and Electro-pneumatic regulator (optional) still keep operating condition,

though.

Stroke rate setting for criterion of warning shall be executed on setting screen No.10.

If actual operating stroke becomes slower than the fixed stroke, then it resets automatically. Also it is able to reset

by reset signal from manual reset device. After reset signal input, it neglects detection for 2 minutes. After

Caution

• Proximity switch cord of FF, FW and FS pumps consists of three wires of black, white and red. Wrong connection
of them will cause the failure of proximity switch.

Caution

1. Standard proximity switch can not be used to handle flammable liquid such as solvent or so. Ask IWAKI for

explosion-proof proximity switch.

2. Electrode can not be used to handle flammable liquid. If used, it may spark resulting in fire.

Caution

• Use power source of DC24V plus minus 10% range.

■Air piping

Figure 5 and 6 show electrical wiring and air piping schemes. Make the air piping according to following procedures
referring to the schemes.
(1) Precautions for air piping

a) Bad quality air will give bad influence to the performance and life of the equipments.

Supply clean air which contains no solid matters, water and oil.

b) Flush pipes before they are connected. When the seal tape is used for piping, pay attention so that the tape can be

get into the pipe.

c) Install a regulator before the electro-pneumatic regulator (option) and adjust supplied air pressure to get the stable

performance.

d) If the electro-pneumatic regulator is not used, connect pipe from manual regulator

(FR) on Fig. 5 and 6 to the solenoid valve.

Note: The secondary side set pressure of manual regulator must not exceed the max. supply air pressure of the pump.

Refer to the instruction manual of the used pump.

(Pay attention to the pumped liquid temperature range.)

(2) Piping of electro-pneumatic regulator

Install the electro-pneumatic regulator between the manual regulator and the solenoid valve. Refer to the
instruction manual of the electro-pneumatic regulator for details.

1. Troubleshooting

Symptom Causes Check point & countermeasure

Pump does not start Defective electrical

wiring line

Confirm wiring between FDC-1 and solenoid valve for pump.
Confirm wiring between FDC-1 and proximity switch.

NO and NC proximity sensor of pump supply are being input to FDC-1
as right and left reversed.

Defective pump proximity sensor.
After power on to FDC-1, confirm output voltage of proximity sensor
without supplying air to pump.
FF pump: voltage between white and black is approx. 24V.
FH, FA pump: voltage between black and blue is approx. 24V.
FS pump: voltage between white and black is approx. 24V.
FW pump: voltage between white and black is approx. 24V.
If the above voltages close to 0V, it seems defective.

Electrode (leak sensor) is conducted.
The sequence is arranged to let inter-lock work among pump, FDC-1

and equipment when pump starts.

Defective air piping
line

Air supply is not provided correctly to the preliminary (IN) side of
Electro-pneumatic regulator EV2000.

Defective solenoid valve.
Minimum air pressure for drive becomes higher due to solenoid valve

run down.
Exhaust outlet of solenoid valve or QEV is covered or closed.

Wrong IN and OUT connection of Electro-pneumatic regulator
EV2500.

Wrong IN and OUT connection of QEV.
Air piping for pilot is not arranged in spite of using solenoid valve for

external pilot way.

Defective liquid
piping line

Liquid valve installed at both sides of pump inlet and outlet are closed.
The sequence is arranged for not to open liquid valve when pump starts

Sufficient filtration size is not secured and it becomes high load due to
entangled filter by air.

Pump stops soon
after it starts.
Time up alarm
outputs.

Improper setting

Too little flow rates.
Resettle value of setting screen No.4.

When the pump discharge side pressure gets lower, the flow control
function of FDC-1 lowers the supply air pressure. When the air
pressure gets lowered, it may happen the pump stops because enough air
pressure to drive the pump can not be kept. If this happens, change the
value on Setting screen No. 6 on page 20 to the value at which the pump
can not stop.

Confirm wiring between FDC-1 and Electro-pneumatic regulator
EV2500.
