WARNING! To avoid operator hazards and damages of

the device, the following instructions have to be worked

out by qualified technical personnel.

1.4 Limitation of liability

By non-observance of the operating manual, inappropriate

use, modification or damage, no liability is assumed and

warranty claims will be excluded.

1.5 Intended use

- The field display PA 440 is supplied by the analogue

current loop and shows the measured value on the dis-

play. For monitoring the limit values optionally up to two

PNP open collector-contacts are available. As standard

the PA 440 is equipped with a LC-display, optionally a

LED-display is deliverable.

- The configuration is menu-driven via two push buttons

located in the front. Following parameters could be con-

figured: decimal point, zero point, end point, switch-on

and switch-off points, etc. Those parameters are being

stored in an EEPROM and, thus, are being kept also in

case of power breakdown. Limit exceeding in both direc-

tions can be displayed as a message. Furthermore an

access protection is provided.

- It is the operator's responsibility to check and verify the

suitability of the device for the intended application. If

any doubts remain, please contact our sales department

in order to ensure proper usage. BD SENSORS is not

liable for any incorrect selections and their effects!

- The technical data listed in the current data sheet are

engaging and must be complied with. If the data sheet is

not available, please order or download it from our

Do not use any force when installing the device to

prevent damage of the device and the transmitter!

3.2 General installation steps

- Carefully remove the pressure measuring device from

the package and dispose of the package properly.

- Next the field display has to be mount stationary on a

suitable fixing location via two appropriate fastening

screws.

3.3 Lead in the transmitter cable

Lead in the connecting cable of the transmitter through

the cable gland on the left side. The cable length inside

the terminal box has to be long enough for connecting

the cords with the terminal clamps on the left

(SENSOR).

Then tighten the cable gland by hand. Take care that

the cable is strain-relieved.

Pay attention that the PTFE-filter on the gauge refer-

ence of BD SENSORS-transmitters may not be dam-

aged or removed.

3.4 Lead in the supply line

Lead the supply line through the cable gland on the

right side. The cable length inside the terminal box has

to be long enough for connecting the cords with the

terminal clamps on the right (SUPPLY).

Then tighten the cable gland by hand. Take care that

the cable is strain-relieved.

4. Electrical Installation

WARNING! Install the device only when currentless!

Supply:

The supply created by the electronics of the device is

approx. 6.5 V

. Please take this into consideration when

planning your power supply. The tolerances for the power

supply can be calculated as follows:
