Precautions for use
• Electrical work should be performed by a qualified electrician. Otherwise,
personal injury or property damage could result.
Le raccordement électrique de la pompe doit être effectué par du person-
nel qualié sinon, il pourrait y avoir un dommage corporel ou incorporel.
• Do not install the pump:
–In a ammable atmosphere.
–In a dusty/humid place.
–In direct sunlight or wind & rain.
–Where ambient temperature can exceed 0-50ºC (32-122°F).
Ne pas installer la pompe dans les endroits suivants:
–Dans une atmosphère inammable
–Dans une atmosphère poussiéreuse ou humide.
–Sous les rayonnements du soleil, dans le vent ou sous la pluie.
–La température ambiante doit être comprise entre 0 et 50°C.
• Select a level location, free from vibration, that won't hold liquid. Anchor
the pump with eight M8 bolts so it doesn't vibrate. If the pump is not in-
stalled level, output may be affected.
Choisissez un endroit où il n’y a pas de vibrations et où le liquide peut
s’évacuer. Fixez la pompe à l’aide de visses M8 de façon à ne pas avoir de
vibrations. Si la pompe est inclinée, le débit peut être réduit.
• When two or more pumps are installed together, vibration may be signifi-
cant, resulting in poor performance or failure. Select a solid foundation
(concrete) and fasten anchor bolts securely to prevent vibration during
operation.
Si plusieurs pompes sont installées ensemble, elles interagissent et les
vibrations peuvent devenir importantes, ce qui engendre des performances
médiocres ou des ratures. Choisissez un endroit solide et xez les boulons
correctement pour évitez les vibrations pendant le fonctionnement.
• Allow sufficient space around the pump for easy access and maintenance.
Prévoyez de l’espace autour de la pompe pour faciliter l'accès et la mainte-
nance.
• Install the pump as close to the supply tank as possible.
Installez la pompe le plus près possible du tank de produit.
• When handling liquids that generate gas bubbles (sodium hypochlorite or
hydrazine solution), install the pump in a cool and dark place. Flooded suc-
tion installation is strongly recommended.
Installez la pompe dans une place froide à l’abri du soleil lorsqu’il s’agit
du dosage de produits dégazant tels que l’hypochlorite de sodium ou
l’hydrazine. Mettre la pompe en charge est vivement recommandé.
• The suction line I.D. should be equal to or wider than the I.D. of the pump.
La ligne d’aspiration doit être plus large que l’entrée de la pompe.
• Build up a flooded suction system for the viscous liquid delivery of
300mPa•S or more.
Pour les liquides ayant une viscosité supérieure ou égale à 300 mPa.s il
faut mettre la pompe en charge.

• Use measures to keep the pump connections free from stress. Weight and
thermal expansion/contraction of the piping can stress connection points.
La pompe ne doit pas être soumise à des effets éventuels de dilation ou de
contraction du pipe dus à un stress thermique.
• Overload protection will stop pump operation when discharge pressures
reach 1.3 to 2 times higher than the pump maximum. If the discharge line
cannot conservatively handle the maximum pressure, use a relief valve to
safely depressurize the discharge line.
Un dispositif de protection en cas de surcharge doit pouvoir arrêter le dos-
age quand la pression au refoulement s’élève de 1,3 à 2 fois le maximum
admis. Installez une vanne de sécurité pour relâcher la pression de la ligne
de refoulement si la ligne de refoulement ne peut pas supporter de haute
pression.
• Use care handling the pump. Do not drop. An impact may affect pump
performance. Do not use a pump that has been damaged to avoid the risk
of electrical damage or shock.
Veillez à ne pas laisser tomber la pompe sur le sol. Un impact important
pourrait réduire les performances de la pompe. Ne pas utiliser une pompe
endommagée sinon il pourrait y avoir un courant de fuite ou une décharge
électrique.
• The pump has a rating of IP65 equivalent, but is not waterproof. Do not op-
erate the pump while wet with solution or water. Failure or injury may result.
Immediately dry off the pump if it gets wet.
La pompe est IP65 équivalent mais n’est pas complètement étanche. Ne
pas laisser la pompe couverte de liquide pompé ou sous la pluie. Il pour-
rait y avoir des ratés ou préjudices. Si la pompe a été mouillée, sechez-la
directement.
• Do not close discharge line during operation. Solution may leak or pump
and piping may break. Install a relief valve to ensure safety and prevent
damaged plumbing.
Ne fermez pas la ligne de refoulement lorsque la pompe est en fonc-
tionnement sinon il pourrait y avoir des fuites de liquide ou la pompe et la
tuyauterie pourraient céder. Installez une soupape de sécurité pour des
raisons de sécurité et pour éviter tout dommage de la tuyauterie.
• Solution in the discharge line may be under pressure. Release the pres-
sure from the discharge line before disconnecting plumbing or disassembly
of the pump to avoid solution spray.
Le liquide au refoulement peut être sous pression. Relâchez la pression
du refoulement avant de démonter la pompe ou d’enlevez le tubage pour
éviter tout jet de liquide.
• Wear protective clothing when handling or working with pumps. Consult
solution MSDS for appropriate precautions. Do not come into contact with
residual solution.
Portez un équipement de sécurité lorsque vous manipulez la pompe. Con-
sultez le MSDS pour utilisez les précautions appropriées. Evitez tout con-
tact avec le liquide chimique.
• Do not clean the pump or nameplate with a solvent such as benzine or
thinner. This may discolour the pump or erase printing. Use a dry or damp
cloth or a neutral detergent.
Ne nettoyez pas la pompe ou la plaque signalétique à l’aide d’un solvant
comme le benzène ou le white spirit. Cela pourrait décolorer la pompe ou
effacer l’impression. Utilisez un tissu sec ou mouillé avec de l’eau ou un
détergent neutre.

Overview
Introduction
Pump characteristics, features and part names are described in this
section.
Introduction
Pump structure & Operating principle
The IX series are diaphragm pumps with a brushless DC (BLDC) motor and feature a high turndown ratio &
automatic controls.
Principle of operation
In the IX series design, a BLDC motor rotation controls the ow rate.
Motor rotation is transmitted to an eccentric cam through a reduction gear and then converted to reciprocating
motion. Volumetric change occurs in the pump chamber as the diaphragm moves back and forth and liquid is
pumped because of the suction and discharge check valves. Discharge speed changes the ow rate while the
suction speed remains the same at any ow rate.

Overview
Features
● High turndown ratio
Use of a BLDC control motor enables accurate control with a wide turndown ratio.
● High repeatability
Highly-efcient valve design and accurate discharge-/suction-speed controls assure the high repeatability of
chemical dosing (±1%).
● Energy-saving design
Use of helical gears and an assist spring reduces power consumption by 70% compared to our existing me-
tering pump designs (spring back).
● Automatic control
The IX can automatically run along with analogue-, pulse-, batch- or interval batch-operation programming.
● Multivoltage operation
The IX series can be used in all countries thanks to the universal power voltage (100-240VAC).
● Safety design
A diaphragm rupture detection ensures user safety and a pressure overload detection protects the pump and
pipework from an accidental discharge line pressure rise.
● Ingress protection rating of IP65
Operational functions
Manual mode
Run/stop the pump by key operation. The ow rate can be changed by the up and the down keys at any time

Overview
ANA. V (analogue variable) programming (see page 42 & 54)
The pump increases/decreases a stroke/ow rate in proportion to 0-20mA. Determine the operational behav-
iour by programming two set points and choosing one of the LINEAR, BOX and LIMIT patterns.
To show the current value, push the key. To return to the ow rate display, push the key.
<LINEAR>
A stroke/ow rate changes with a current value by a programmed line.
Condition:
Set Point 1 (SP.1) = Ampere : 6mA, Flow rate : 90L/H
Set Point 2 (SP.2) = Ampere : 17mA, Flow rate : 255L/H
<BOX>
A stroke/ow rate changes with a current value by a programmed line. The rate does not exceed the Set Point

■ Pulse control (see page 42 & 54)
The ow rate is automatically controlled by the ow volume (ml) per pulse and the pulse signal frequency from a
ow meter.
* It takes about 10 pulses for the IX to catch up with the change of the frequency.
Example of use: Chemical dosing in a sewage treatment system
■ Batch control (see page 42 & 54)
The IX discharges a programmed ow volume per pulse and stops when it is completed. The programmed or
remaining ow volume is shown on the controller until it has reduced to zero. In this control mode, the pump
runs at the MAN speed (the pump speed in the manual mode). The pump behaviour can change depending on
the setting of the buffer. See below.
When the buffer is OFF:
Any input of the external pulse signal will be cancelled when the pump is activated for the earlier pulse input.
The next dosing becomes ready after the programmed ow volume has been completed.
*Note the control stops immediately when the key is pushed once.

Overview
Example of use: Chemical dosing in a production line system
When the buffer is ON:
Every time the external pulse signal is inputted, the programmed ow volume per pulse is accumulated (max
65535 pulses) even when the pump is activated for the earlier pulse input.
*The control stops immediately and all the pulse accumulation is cleared when the key is pushed once.
Pulse input by the key:
Instead of the pulse signal input, pushing the key can start or stop the batch control. In this case, the pump
behaves as the control with the buffer OFF even when the buffer is set to ON in the batch control mode.

■ Interval batch control (see page 42 & 54)
To make an interval batch control, set a date and time interval and the ow volume. The IX discharges the pro-
grammed ow volume at a set interval. In the diagram below, the interval is set to 1 hour.
* The pump runs at the MAN speed. The control is triggered by either the external pulse signal or the push of the key.
Push the key to stop the control when it is triggered by the key.
Example of use: Water transfer for a sprinkler system
AUX function
The pump runs at the AUX speed while receiving the external signal via the AUX terminal. See page 51.
* This function works only when the pump is running in either MAN or EXT mode (see page 40.). The pump returns to the
MAN or EXT mode once the AUX signal stops.
Priming function
The pump runs at the MAN speed (or the maximum stroke rate with default setting) while both the UP and
DOWN keys are pressed. Use this function for priming or degassing. Release both the keys to stop the pump.
See page 55 for detail.
* This function is available at any time except when the pump is in the MAN/EXT selection or menu selection (see page 40.).

Overview
STOP functions
■ STOP function (see page 45)
The start/stop of operation can be controlled by the signal from a level sensor. The operation LED changes
from green to red colour when the pump is receiving the Pre-STOP signal from a level sensor in operation.
See page 32 "STOP IN" for wiring diagram.
Example of use: Liquid level monitoring
The pump stops when liquid has fallen below the minimum level.
■ Pre-STOP function (see page 45)
Liquid level in the supply tank can be monitored by the signal from a level sensor. The operation LED changes
from green to orange colour when the pump is receiving the Pre-STOP signal from a level sensor in operation.
See page 32 "STOP IN" for wiring diagram.
Example of use: Liquid level monitoring
The operation LED lights in orange colour to inform a user that liquid comes
close to the minimum level in a supply tank.
Analogue output function
The pump transmits the 0-20mA analogue signal in proportion to the preset ow rates (see page 46).

Protective functions
■ Interlock function (see page 32 & 47)
Interlock function works in the same way as the STOP function but uses a preference circuit. Use this function
for emergency stop.
■ Diaphragm rupture detection (see page 45)
The pump stops right after a built-in sensor detects a leak in the compartment at the back of the diaphragm. In
this condition, the operation LED lights in red colour. Replace a broken diaphragm as necessary. See page 63
for diaphragm replacement. To release this error condition, push the start/stop key (or the ESC key if the pump
is under the Probus control.).
NOTE
This capacitance sensor does not work properly if liquid conductivity is 1mS/m or below. Before sending pure
water, oil or any other low-conductivity liquid, check the conductivity to see if it meets the minimum detection
level. If it is not satised, the leak sensor is no longer usable. In this case a leak from the drain port is the
only valid indicator. In either case, replace the diaphragm immediately when a leak is found.
■ Pressure overload/Failed rotation control detection
The pump stops with the red operation LED blinking when a built-in pressure sensor detects 1.3-2.0 times high-
er discharge pressure than the maximum level or when the hole IC which monitors the motor rotation has failed.
If the pump is suspended (by the over-current protection) in either condition, the pump resumes operation 30
seconds later. If the suspended operation has recurred 5 times consecutively, the pump will not resume opera-
tion any more and will keep still. These error conditions can be released when the start/stop key is pushed once.
NOTE
The discharge pressure can rise 1.3-2.0 times higher than the maximum allowable level of the pump de-
pending on operating conditions and piping layouts. Also, if the pressure rises too sharp (with the closed dis-
charge), it may not be even detected or curbed by the over-current protection. Set up a relief valve to protect
the related devices on the discharge line from the possible pressure rise if their pressure resistance is low.
