¡When a tightening valve is located on the discharge piping, and when there is a risk of blockage, be sure to

CAUTION

WARNING

CAUTION

WARNING

install a relief valve on the piping immediately on the discharge side of this pump. When a valve has been tightened or foreign matter clogs the discharge piping of the pump, the pressure in the pump may increase beyond the range indicated in the pump specifications. This may result in chemicals spurting out, damage to the piping or malfunction of the pump, which are dangerous.

¡To prevent chemical leakage from the relief valve return piping, return the tip of the piping to a tank or other

receptacle.

¡This pump is made to outdoor specifications. It is, however, made of plastic so try to avoid installing it at

locations that will shorten its life (e.g. where it is exposed to direct sunlight or wind and rain).

¡When using water-diluted solutions in cold areas, chemicals may freeze in the pump head or piping, damaging

the pump and peripheral parts. Be sure to install heating apparatus or heat insulation.

¡Water used in the pre-shipment test may remain on pump liquid-end parts. When using chemicals that generate

gas or harden due to reaction with water, be sure to drain any water and allow liquid-end parts to dry before use.

¡Generally, the pressure-resistant performance of hoses is impaired when they become hot. When using

commercially available hoses, be sure to use hoses that can resist the operating temperature and pressure as well as being resistant to chemicals. Otherwise, the hoses may become damaged or chemicals may spray from the piping.

¡The durability of hoses varies considerably depending on the chemical used, temperature, pressure, and UV

rays. Inspect the piping, and replace it if it has deteriorated.

¡Do not apply excessive force on the cover as it is made of plastic. Doing so might damage the cover.

Electrical Wiring

¡Do not operate this pump with wet hands. Doing so might result in electric shock. ¡Do not turn the power ON during electrical wiring. Attach a "Work In Progress" label to the power switch. ¡Reliably ground the ground terminal. Failure to do so might cause electric shock. Be sure to install a current

leakage breaker.

¡Do not disassemble the body or circuits.

¡Electrical wiring must be performed by personnel such as an electrician having specialist knowledge. ¡Check the power voltage before wiring. Do not wire a power supply outside of the rated voltage range. ¡Be sure to ground the earth lead (green-yellow) when wiring to prevent electric shock.

Operation and Maintenance

¡Only the operator or administrator is allowed to operate this pump. ¡Do not operate this pump with wet hands. Doing so might result in electric shock. ¡If anything unusual occurs such as smoke or a burning smell during operation, immediately stop operation and

contact your supplying agent. Failure to do so might result in fire, electric shock or damage to the product.

¡Do not disassemble the body or circuits. ¡During air release, chemicals spray forcefully from the tip of the piping. Either release air using water or other

safe liquid, or return the tip of the air release piping to the tank. During this operation, either hold the air release hose by hand or secure it in position.

¡When a valve has been tightened or foreign matter clogs the discharge piping of the pump, the pressure in the

pump may increase beyond the range indicated in the pump specifications. This may result in chemicals spurting out, damage to the piping or malfunction of the pump, which are dangerous. Check the valves before the operation.

¡Before disassembling liquid end parts for maintenance or repair, be sure to turn the power OFF and make sure

that no voltage is being applied to the pump.

¡Do not turn the power ON during electrical wiring. Attach a "Work In Progress" label to the power switch. ¡When handling liquid-end sections, be sure to wear protective coverings (rubber gloves, mask, protective

goggles, chemical-resistant overalls, etc.) appropriate for the chemicals be using used.

¡Before maintaining or repairing the pump, be sure to release the discharge-side pressure, drain the chemicals

from liquid-end sections, and wash the pump with water.

¡Pump vibration sometimes causes hoses to become loose and disconnected. Before starting operation, make

sure that tubes are secured in position and tightened.

¡During operation, the surface of the pump sometimes reaches or exceeds 60°C. When touching the pump during

operation, be sure to wear protective coverings that can resist high temperatures.

¡Idling the pump for a long time may cause the pump to malfunction. Do not idle the pump for more than one

hour.

Other

CAUTION

¡Do not remodel this pump. ¡Adopt preventative measures such as a chemical drain ditch in case chemicals flood out of the pump. Also,

Explanation of Product

The metering pump PZiG Series accurately feeds a fixed amount of liquid for a fixed period of time. Liquid is fed by action of the check valve inside the pump head and volumetric changes in the pump head that occur by reciprocating motion of the diaphragm driven by the force of the electromagnet (solenoid). This structure ensures that the discharge volume per single operation of the pump is fixed. The pump can be used on a power supply within the voltage range 90 to 264 V. A CPU is located inside the pump, which means that various control action can be achieved by externally input signals and pre-input programs. Control action states can also be output to external devices.

This pump is not designed to explosion-proof specifications. It cannot be used in explosion-proof areas, and in explosive/ignitable atmospheres.

Install the pump in locations out of reach of personnel other than an administrator.

Installation Site

• Avoid installing the pump in the direct sunlight. Also, prevent it from being exposed to wind and rain. Though this pump is designed for outdoor use (IP65), temperature sometimes builds up on metal parts due to direct sunlight, plastic parts sometimes become impaired due to UV rays, and scratches and rusting sometimes occurs due to sand, dirt and rainfall. To extend the service life of the pump when it is installed outdoors, we recommend installing an awning or shade cover.

If you have forgotten to open a valve or foreign objects are blocking the piping on the dischargeside of the pump, an excessive pressure rise that will exceed the pump's specification ranges may occur, liquid may spray out or piping may be damaged, which is dangerous.

• Install the pump on a flat horizontal surface and fix it securely to prevent it from vibrating during operation. If the pump is installed on an inclined surface, the pump may not be able to discharge properly or at all.

Installation

• Install the pump in a location that is well-ventilated during summer, and where chemicals will not freeze in winter.

• Leave enough space to allow easy access for maintenance and inspection work.

Position of Installation Bolts

Use the four pump fixing bolts (supplied) to secure the pump in position.

• Maintenance space.

Piping

This section mainly describes hose connection type piping. Contact TACMINA separately for details of other types of piping.

Requests during Piping

Installation

●Pulsation

• The hoses on this pump vibrate as this pump generates pulsation. Secure this pump in such a way that hoses do not vibrate.

• We recommend installing a damper to reduce pulsation. Contact TACMINA separately.

●Length of Piping

• If the hose is too long, pressure loss might increase, causing the pump's permissible pressure to be exceeded and overfeed to occur or the pulsation to occur on the piping.

• A total of three meters of hose is provided on the discharge and suction side. In particular, when extending the discharge-side piping beyond two meters, pressure loss might exceed the pump's maximum discharge pressure. So, a damper must be installed or thicker piping must be provided. Notify your supplying agent of (1) viscosity of the liquid, (2) length (positional relationship) of the piping, (3) specific gravity of the liquid, and other information. On the 1300 type, when extending the discharge-side piping beyond two meters, be sure to install a damper. Select a damper and the optimum piping size.

●Maintenance

• When removing hoses during maintenance, for example, and the same hose is to be used again, cut the tip of the hose by about 10 mm before inserting it.

• Before performing maintenance, open the discharge-side piping to release pressure to the air.

●Bending Hoses

• Provide sufficient margin (in the case of 12 ✕ 18 mm dia. PVC braided hose, a radius of 100 mm or more) to prevent the hose from folding. Prevent hoses from being folded, rubbed, cut, or trodden on. Failure to do so might damage the hose.

• Minimize bending of hoses that might lead to piping becoming bent or resistance occurring in the flow in joints, for example.

●Floor installation procedure

The following explains an example where a TACMINA tank is used.

1Remove the hose nut on the tank side, pass the

suction-side hose through the nut, connect the hose to the suction valve on the tank, and tighten the hose nut.

2Connect the hose to the suction-side hose joint

on the pump by the same procedure as in (1) above.

3In the same way, connect the discharge-side

hose to the discharge-side hose joint on the pump.

4Install the anti siphonal check valve at the injec-

tion point.

5Connect the discharge-side hose to the anti

siphonal check valve.

• We recommend installing a relief valve for automatically releasing abnormal pressure to air in the discharge-side piping.

• Install a pressure gage on the discharge-side piping to measure the pressure on the pump's discharge side.

• Install the pump as close as possible to the chemical tank. If the suction-side piping is too long, cavitation sometimes occurs and metering performance can no longer be ensured.

¡A circuit protector (CP) is ideal as an overcur-

rent protection device on this pump from the aspects of operating time and shutoff current characteristics. (5 A medium-speed type)

¡ The circuit protector indicated as a recom-

mended protective device can also be used as a power supply switch, which simplifies wiring.

¡A thermal relay for a motor is unsuitable for

protection of this pump from the aspect of characteristics.

●Standalone operation

¡Be sure to use a commercial power supply

(power supplied from an electric power company) as the power supply.

¡Power supplies that cannot be used:

1.Power supply equipped with an AC power regulator

2.Power supply on the output side of the inverter

¡Do not take power in from the same terminal as

an induction motor (e.g. transfer pump). A high voltage may be generated, for example, when the power is turned OFF and damages the pump.

Setting the Discharge Volume

Outline

On the PZG, the discharge volume can be set by performing the following setup on the operation panel. Before you set the discharge volume, calibration must be performed, and the maximum discharge volume per minute must be set in advance. For details on the calibration method, see "Calibration" (page 16).

Operation

Operation Panel

• Manual mode Sets the strokes (spm, %) or discharge volume (mL/min).

• Analog mode The stroke spm is varied by an external signal (analog signal) to control the discharge volume.

• Pulse mode The stroke spm is varied by an external signal (pulse signal) to control the discharge volume.

• Counter mode Pump operation is performed for the number of preset strokes after the start signal is received to control the discharge volume.

• Interval mode Pump operation is turned ON/OFF using an internal timer function to control the discharge volume.

Calibration

The calibration procedure is as follows. The figures below are for a PZiG-1000. (1) Install the pump and pump to match the actual piping conditions, and set to the trial operation mode (2) Pour the solution to be actually used into a measuring utensil (e.g. graduated cylinder) capable of measuring the

maximum discharge volume per minute of pump operation.

(3) Insert the suction-side end of the pump piping into the graduated cylinder, and

release air.

* It is more convenient to use the measuring piping if this is provided on the tank.

(4) Turn the stroke length adjusting dial to set the actual stroke length to be used.

Do not change the stroke length after the maximum discharge volume has been set.

(5) Press the MODE key several times until the display changes to mL/min.

If the pump is operating, press the STOP key to stop pump operation before performing this operation.

(6) Press the SET key to display the discharge volume setup screen. Press the FUNC key to enter the calibration

mode.

Operation

(7) Note down the level of the solution in the graduated cylinder. (8) Press the START key.

The pump operates for one minute (300 times) and comes to a stop. (9) Check the level of the solution in the graduated cylinder, and measure the amount of decrease of the solution. (10) Press the FUNC to return to the discharge volume setup screen.

(11) Press the UP/DOWN key to set to the value calculated in step (9). (when the measurement value is 1010 mL) (12) Press the SET to return to the discharge volume setup screen.

Remarks

When the screen returns to the discharge volume setup screen, the discharge volume setting value will not change. However, the stroke spm of the pump has changed. (13) Set the discharge volume as necessary using the UP/DOWN key. (14) Turn the pump OFF, and restore the piping.

■Calibration

The specification capability of this pump is the maximum discharge volume at 300 strokes (on the PZiG-1000, 1000 mL/min). However, the discharge volume does not always match the actual discharge volume depending on the operating conditions, product differences, and stroke length setting. For this reason, the actual discharge volume per 300 strokes is measured, and the maximum discharge volume is stored to the pump's memory. This eliminates any error between the preset discharge volume on screen and the actual discharge volume.

Setting the Discharge Volume

Display Operation Explanation

In the manual mode, the number of strokes can be changed during pump operation or when pump operation has stopped.

In other modes, stop pump operation by the STOP key, and press the MODE key several times to set the manual mode.

Default is 300 spm.

Press the UP/DOWN key to set the number of strokes within the range 0 to 300 spm. (in single step increments)

The number of strokes (spm) blinks.

If you do not touch any of the keys for two seconds after setting the number of strokes, the numerical value you entered is determined, and the number of strokes stops blinking and lights.

This completes changing of the setting value.

If the pump has stopped, press the START key to start operation.

The pump enters the run mode, and STP goes out.

* If the screen on the left is displayed during pump operation, the number of strokes can be changed. Press the UP/DOWN key to change the number of strokes.

If you do not touch any of the keys for two seconds after changing the number of strokes, the change is reflected.

Troubleshooting

WARNING

IMPORTANT

Do not operate this pump with wet hands. Doing so might result in electric shock.

Make sure to turn OFF the power before disassembling the liquid end and check that the power is not applied to the pump. Do not start the disassembly only by stopping the pump with a key. Attach a "Work In Progress" label to the power switch so that the power cannot be turned ON during repair works.

When handling liquid-end sections, be sure to wear protective coverings (rubber gloves, mask, protective goggles, chemical-resistant overalls, etc.) appropriate for the chemicals be using used.

Before maintaining or repairing the pump, be sure to release the discharge-side pressure, drain the chemicals from liquid-end sections, and wash the pump.

¡We recommend using the flow indicator as a means of detecting defective discharge.
