Outputs

Current output / Loop current

The loop current is controlled by the process variable selected

in the configuration.

The current start and end can be set to represent any desired

value. To check connected peripherals (e.g. limit switches,

controllers), the loop current can be manually specified

(see Pg. 41).

HART communication

The Transmitter Cond Ind 7100e/2(X) can be remote-controlled

via HART communication. It can be configured using a hand-

held terminal or from the control room. Measured values, mes-

sages and device identification can be downloaded at any time.

This allows easy integration also in fully automatic process

cycles.

A list of the HART commands can be found in the “Transmitter

Cond Ind 7100e/2(X) Transmitter-Specific Command

Specification”: www.mtpro.com/transmitters.

Alarm

The alarm delay is configurable.

Error messages can also be signaled by a 22 mA loop current

(see Configuration, Pg 55).

The alarm LED on the front panel can be configured as follows:

HOLD off: Alarm: LED flashing

HOLD on: Alarm: LED on. HOLD: LED flashing.
