Explanation of symbols

WARNING!

... indicates a potentially dangerous situation that can result

in serious injury or death, if not avoided.

Information

... points out useful tips, recommendations and information

for ecient and trouble-free operation.

2. Safety

WARNING!

Before installation, commissioning and operation, ensure

that the appropriate dierential pressure switch has been

selected in terms of measuring range, design and specic

measuring conditions.

Non-observance can result in serious injury and/or damage

to the equipment.

Further important safety instructions can be found in the

individual chapters of these operating instructions.

2.1 Intended use

This electronic dierential pressure switch is used for monitoring the

dierential pressure of air and other non-inammable and non-aggres-

sive gases. And also for controlling air as well for monitoring of air lters,

blowers in ventilation ducts, control of air and re shutters, for overpres-

sure monitoring in clean rooms and laboratories.

The instrument has been designed and built solely for the intended use

described here, and may only be used accordingly.

The manufacturer shall not be liable for claims of any type based on

operation contrary to the intended use.

damage to equipment.

■

The activities described in these operating instructions

may only be carried out by skilled personnel who have

the qualications described below.

Skilled personnel

Skilled personnel are understood to be personnel who, based on their

technical training, knowledge of measurement and control technology

and on their experience and knowledge of country-specic regulations,

current standards and directives, are capable of carrying out the work

described and independently recognising potential hazards.

6. Commissioning, operation

Installation

■

When connecting the instrument, the process lines must be free of

pressure.

■

Observe the suitability of the instrument for the media to be

measured

■

Observe maximum pressures

Electrical connection

The instruments are designed to operate with safety extra-low voltage

(SELV). When wiring up the instruments, the technical specications

for those instruments should be followed. In the case of a sensor with

transmitter, as a rule, the transmitter should be operated in the middle of

the measuring range, since deviations can occur at the range limits.

■

The ambient temperature of the transmitter electronics

should be kept constant.

■

Current/voltage spikes from switching the power supply

on or o must be prevented by the customer.

Current consumption

35 mA + switch (7 mA each) + instrument with automatic zero

adjustment (20 mA)

0 … 10 V output (10 mA), max. 80 mA

5.2 Packaging

Do not remove packaging until just before mounting.

Keep the packaging as it will provide optimum protection during transport

(e.g. change in installation site, sending for repair).

5.3 Storage

Permissible conditions at the place of storage

Storage temperature: -20 ... +70 °C

Protect the instruments from moisture and dust.

To access the menu, press the "MENU" button for approx. 3

seconds.

To exit the menu, press the "BACK" button.

To open an individual menu point, and to accept the changes,

press the "OK" button.

These buttons enable you to scroll within the menu.

Output signal 0 ... 10 V

Power supply AC 24 V

Relay 1 (standard)

Relay 2 (option)

If the voltages being switched via the relays

are not in accordance with SELV, then the

power supply and signal/control cables of

the relays should be installed so that they

are separated. A separate cable entry is

available for both.

Commissioning

A prerequisite for the commissioning is a proper installation of all

electrical supply, control and measuring lines and of the pressure

connection lines.

■

Before commissioning, the leak tightness of the pressure

connection lines must be checked.

Zero point adjustment

Attention!

Connect the voltage supply one hour before making the

zero point adjustment.

■

Remove both hoses from the pressure connections ⊕ and ⊖.

■

Press both the "up" and "down" buttons simultaneously, or select

"Zero" in the setting menu:

⇒ the green LED switches o and "Zero" is shown in the display.

■

Wait until the green LED switches back on, then reconnect the ⊕ and

⊖ pressure connections.

In normal operation, we recommend that a zero point adjustment is

carried out every 12 months.

Span calibration

Attention!

Connect the voltage supply one hour before making the

span calibration.

A reference pressure measuring instrument is needed for the span

setting.

The span should not be set without pressure being present. If the span

is set with either no test pressure, or too-low a pressure, the instrument

will lose its accuracy and no longer give correct measured values.

If this should occur, select the menu point "Span" and then select

"Reset", in order to reset the span setting.

Set the span in the following sequence:

1. Carry out a zero point calibration

2. Connect the pressure connections

3. Select "Span" in the menu and then select "Adjust"

4. Using both the "up" and "down" arrow buttons, set the relevant value

for the display or the 0 … 10 V output, so that it matches the reference

pressure instrument's value

5. Conrm the setting by pressing the "OK" button

7. Maintenance and cleaning

The dierntial pressure switches are maintenance-free and oer long

service life provided they are handled and operated properly.

Clean the instruments with a moist cloth (soap water).

Repairs must only be carried out by the manufacturer or appropriately

qualied skilled personnel.

8. Disposal

Incorrect disposal can put the environment at risk.

Dispose of instrument components and packaging materials in an

environmentally compatible way and in accordance with the country-

specic waste disposal regulations.
