Describes setting item, operating condition and contents of alarm for each pump in English abbreviation. (2 lines, 16

alphabets)

②key, key and key :

key: To be used for writing selection of each setting value. At that time, ENTER key will be used for

confirmation of figure down of value and operation.

By the combination of MENU key and SELECT key, it is able to access to each setting screen individually.

key: The designation of setting screens No., changeover of Stop & Run and Alarm reset can be executed.

③Controller operation mode selection key (MANU operation):

When LED turns on by depressing key, operation mode can be switched to manual operation mode.

Manual mode can effect all sort of setting and work on the panel manually.

④Controller operation mode selection key (AUTO operation):

When LED turns on by depressing key, operation mode can be switched to automatic operation mode.

Automatic operation mode can effect all sort of setting on the panel manually, and remote operation can be effected

for pump start, pump stop and alarm reset respectively by zero voltage contact signal or open collector signal.

⑤LEDs:

There are 5 LEDs in total. The explanation of each LED is as follows.

RUN: Turns on while pump is operating. (Green)

LEAK: Turns on when leak alarm is detected. (Red)

TIME: Turns on when time-up alarm is detected. (Red)

LIFE: Turns on when life alarm is detected. (Red)

FAST: Turns on when fast alarm is detected. (Red)

⑥Exclusive connector for alarm output signal (CN1):

At the same time of each alarm detection, each alarm output signal are made out to the external. Connect this

controller and your equipment with an output cable (optional).

⑦Connector exclusively used for driving solenoid valve (CN2):

Solenoid valve driven signal will be generated. Then, connect this controller and solenoid valve (single or double

solenoid valve) with an output cable (optional).

⑧Connector exclusively used for pump input (CN3) :

This connector effects to input the signal of proximity switch and leak sensor. Connect this controller and pump

with an input cable (optional).

⑨Connector exclusively used for external input (CN4):

This connector effects to input signals of pump start, pump stop and alarm reset respectively from the external.

Connect this controller and your equipment with an input cable (optional).

⑩Connector exclusively used for electro-pneumatic regulator (CN5):

This connector generates regulator control signal for flow rate control. Connect this controller and electro-

pneumatic regulator with an output cable (optional).

⑪Connector exclusively used for power supply (CN6):

This connector supplies DC24V + / - 10%.

Connect this controller and power supply with a cable for power supply (optional).

(1) Pump operation:

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

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

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

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

⑤The 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

2minuites, it may start again if it is in alarm condition.

①Possible to fix a specified flow rate control against the load fluctuation at discharge side.

②Possible to set flow rate freely.

③Possible to display stroke rate, flow rate and total count number while pump is operating.

④In case of bellows broken, leak alarm will be output to the externals. Pump stops simultaneously with alarm output.

⑤Possible to set necessary time set for 1 shot of pump operation. When the time for 1 shot of pump is beyond the

setting time, time up alarm will be output to the externals.

⑥Possible to set total counts number of pump. When count number for 1 shot of pump is beyond the setting number,

life alarm will be output to the externals.

⑦Possible to set maximum counts stroke rate. When count number for stroke is beyond the setting number while its

operation, first alarm will be outputting to the externals.

⑧Possible to set alarm reset for start / stop of pump by signals from the externals.

⑨Possible to select operation mode of controller from MANU and AUTO.

⑩In case of proximity switch broken, possible to operate pump by timer mode until proximity switch is replaced.
