GOOD PRACTICES AND SAFETY INSTRUCTIONS

Safety recommendations

If the device is supplied with 100 / 240 V AC, it is mandatory to connect it to the ground with

a good link to the ground, to protect against electric hazard or electrocution.

It is dangerous to change the status of the outputs.

They can control power actuators or other equipment (mechanical, pneumatic, hydraulic,

electrical or other) which can cause serious personal injury and damage to surrounding

material.

For safety and quality measurement reasons, it is important, before powering on the device,

to ensure that it is air supplied with a minimum operating pressure (0.6 MPa ± 15%).

Recommendations for the test environment

Keep the test area as clean as possible.

Recommendations for operators

ATEQ recommends that the operators who use the devices have training and a level of

qualification that correspond to the job to perform.

General recommendations

—Read the user manual before using the device.

—All electrical connections to the device must be equipped with safety systems (fuses, circuit

breakers, etc.) adapted to the needs and in accordance with the applicable standards and

rules.

—To avoid electromagnetic interference, electrical connections to the device must be shorter

than 2 meters.

—Power supply plug must be grounded.

—Disconnect the device from the mains before performing any maintenance work.

—Shut off the compressed air supply when working on the pneumatic assembly.

—Do not open a connected device.

—Avoid splashing water on the device.

ATEQ is at your disposal for any information concerning the use of the device under maximum

safety conditions.

We draw your attention to the fact that ATEQ cannot be held responsible for any accident

related to a misuse of the measuring instrument, the workstation or non-compliance of the

installation with safety rules.

In addition, ATEQ declines anyresponsibilityfor the calibration or the fitting oftheir instruments

that is not done by ATEQ.

ATEQ also declines any responsibility for any modification (program, mechanical or

electrical) of the device done without their written consent.

AIR QUALITY REQUIREMENTS

The air supplied into the device must be clean and dry. Even though the device is provided

with a filter, the presence of dust, oil or impurities may cause malfunction.

Air quality requirements according to ISO standard 8573

The air must be clean and dry.

The presence of impurities, oil or humidity in the air may cause deterioration which will not

be covered by the warranty.

When the instrument is working in vacuum conditions, impurities must be prevented from

being drawn into its internal components.

For this purpose, we strongly recommend that a suitable airtight filter is installed between the

part under test and the instrument.

ATEQ recommends the following characteristics for the air supplied into the device.

Recommended additional equipment

ATEQ recommends the installation of this additional equipment:

—Air dryer to provide dry air at less than - 40°C dew point

—25 microns and 1/100 microns double filter

Preamble

ATEQ ERD620, AN UNIVERSAL VALVES TESTER

ATEQ ERD620 is a pressure ramp generator with the options Contact event or Flow event.

ATEQ ERD620 can memorize 128 different test programs.

QSG_ERD620_421.00_EN_01 / 2020-09-09

FLOW RATE TEST

The purpose of the instrument is to generate a pressure ramp in a valve and detect a flow

event (ex: valve opening). Aramp down can also detect when avalve is closed. The instrument

will display the event pressures and compare them to reject levels. As an option the flow event

can be replaced by a dry contact event.

The ATEQ ERD620 can do direct or indirect measurements. In both cases, the flow meter can

work in vacuum (optional).

Measurement principle

When the fluid (gas) enters the device

,itmoves through a calibrated flow tube

5 Part under test

Direct measurement

Once the part is filled, the device measures the flow rate through the part.

The test pressure is applied to the device 1 and then to the input of the part under test 2.

Indirect measurement

The indirect measurement (also called recovery mode or under bell) allows a considerable

gain in time as the flow which enters into the device is already stabilized.

The test pressure is first applied to the input of the part under test

and then to the

device

2. The output of the device 2 is vented to the atmosphere.

Thismethodallows totestthe parts atahigher pressure test (upto2MPa).

1 Part under test

2 Device

Depending on the part type, it may be possible to use a bell (ex: shower head where

it is impossible to recover the flow other than through the use of a bell). This method can

only be used if the recovery of the flow is easy.

PRINCIPLE OF A CYCLE

The measurement cycle is made of 4 main phases: fill, stabilization, test, dumping.

A Pressure auto zero additional phase 0can be placed at the start or at the end of a cycle,

depending on the requirement of the operator.

0 Pressure auto zero phase (optional)

1 Flow auto zero (0.8s) + Pressure up

time

2 Flow auto zero (0.8s) + Step time

3 Pressure down time
