WARNING
RISK OF DEATH OR INJURY DUE TO UNINTENTIONAL ALTERATION OF THE
EX-RELEVANT PARAMETERS.
Explosion protection is no longer guaranteed.
Remove the programming enable again after deliberately changing
parameters.
After changing or adapting parameters, a subsequent functional test
must be performed.
The programming enable must be connected and activated in order to change
settings and set point values on the device.
It must only be connected during the deliberate modification of parameters.
After changing or adapting parameters, a final function test must be performed.
During normal operation of the Ex p system it may not be connected.
The BARTEC parameter-setting switch must
be used to change the parameters.
The temperature sensor can be a PT 100 or
1000. Settings for the sensor are made in
the device. Two or three wire sensors can be
used.
