Before initial operation check the suitability for the intended
application.
3.1 Functional description
The temperature transmitter serves for the conversion of a
resistance value or a voltage value into a proportional current signal
( ... 20 mA). The analogue signal is transmitted to a series-
connected logic unit, e.g. an SPS or an alarm contact, where
it is monitored for upper deviations from a maximum value or
lower deviations from a minimum value. For failure monitoring the
logic unit has to be capable of recognising HI alarms (adjustable
from 21 ... 22. mA) as well as LO alarms (3.6 mA). The electrical
components of the transmitter are arranged in a plastic case and
completely encapsulated.
