5.5. Temperature of measured medium can not cause increase temperature housing of transmitter above

the ambient temperature Ta specified for a given category

5.6. Supply voltage min. 13,5VDC **

5.7. Load resistance:

from 28V linear supply

Ro max [Ω] = for transmitter without display back lighting

from a source with “trapezial” or “rectangular” characteristic supply

Ro max [Ω] =

*) barrier resistance

**) 16,5V for transmitter with display back lighting

6. How to connect Ex transmitters DPC…, DPR…

The transmitter and other devices in the measuring loop should be connected in accordance

with the intrinsic-safety and explosion-safety regulations and the conditions for use in

dangerous areas.

Failure to observe the intrinsic-safety regulations can cause explosion and the resulting hazard

to people.

The transmitter is equipped in additional communication resistor RD = 240Ω

During normal operation terminals <Signal –> and <Test –> are shorted.

RD resistor is used when you wish to communicate with the transmitter locally (from its terminals)

and Ro < 250. Terminals <Signal –> and <Test –> must be opened.

Transmitter electrical installation should be realised with engineering standard requirements.

It is not allowed to repair or otherwise interfere with the transmitter’s electrical circuits in any

way. Damage and possible repair may be assessed only by the manufacturer or another

authorized party.

Special conditions for safe use:

- Version of transmitter with surge arrester, marked on the plate "SC, SA", does not meet the

requirements of Section 10.3 of the EN 60079-11:2012 (500Vrms). This must be taken into account

when installing the equipment.

In hazardous areas, connections

to the control terminals must be

made using only instruments which

are permitted to be used in such areas.

Hazardous area

To measure the current in the transmitter without

disconnecting the signalling circuit, connect

a milliammeter to control sockets TEST+, TEST-.
