Features of EHN-YN series

High Resolution

Equipped with a digital controller. Precise setting from 1 to 360 shots per minute, adjustable in one shot increments. When combined. When combined with stroke length adjustment, it enables a wide range of flow rate settings.

Multi Hose Connection

This design eliminates hose twisting during connection.

• The following items are not compatible.
Pumps: EHN-□□FC, EHN-□□SH
Accessories: Check valve CS type, Check valve (Without back pressure) CV type, Back pressure valve BV type

Air Vent Valve

Simply turn the air vent knob to release from the pump head.

• Not included with some types.

Universal Voltage

Universal voltage for all models (100 – 240VAC). Free worrying about power voltage.

Water/Dust-Proof

The sealed design of the drive and control unit ensures IP66 equivalent protection.

• Please provide a cover when using outdoors.

Controller function

Manual operation

Pump start/stop is done key input. Stroke rate is adjustable (1–360 spm).

EXT operation

Multiplier (1 : n)
For one pulse signal input, the pump can operate 1–999 times.

Divisor (n : 1)
For 1–999 pulse signal inputs, the pump can operate once.

STOP function

Pump start/stop is controlled by signal input, enabling easy integration with a level sensor or other devices. The controller settings allow the ON/OFF behavior to be Inverted when a STOP signal is input.

Analog input operation

Proportional control of stroke rate between two points
Allows proportional stroke rate control between two user defined points (4–20mA).

• Both 4-20mA and 0-20mA settings are supported.

Auto restoration

Detects the discharge condition and automatically performs a recovery operation in the event of an air lock or other discharge abnormalities.

• Available only when used with the Flow checker FCM.

PA mode
If the flow checker signal stops due to a discharge abnormality and this state continues beyond the preset time, the pump recovers by operation at the maximum stroke rate.

PA+AL mode
If the PA operation continues beyond the preset time (AL time), the pump recognizes this as a discharge abnormality and stops.

PA+AL+RE mode
If discharge is restored during the PA operation and the flow checker signal exceeds the preset time, the pump returns to the stroke rate set before the PA operation.
