SWITCHING OUTPUTS
The ETS 300 has 1 or 2 switching outputs. The following settings can be made under the basic
setting:
7.1.1 Switching point setting (SP)
One switching point and one hysteresis can be set for each switching output. The respective
output switches when the pre-set switching point is reached and switches back when the
temperature falls below the switch-back point. The switch-back point is determined by the pre-set
hysteresis (switch-back point = switching point minus hysteresis).
Abbreviations:
7.1.2 Window function setting (WIN)
The window function enables a range to be monitored. For each switching output, an upper and a
lower switching value can be input which determine the range.
The respective output switches when the temperature enters this range. Upon leaving the range,
i.e. when the switch-back value has been reached, the output switches back. The lower switch-
back value is just below the lower switching value (Lo. minus three times the increment (see table
under point 7.4)). The upper switch-back value is just above the upper switching value (Hi plus
three times the increment). The area between switching and switch-back value forms a safety
zone which prevents unwanted switching operations from occurring (e.g. during very slow rise in
temperature). Example for switching output 1 (normally open function):
Abbreviations:
"hi.1", "hi.2"
= High level 1 or 2
"Lo.1", "Lo.2"
= Low level 1 or 2
NOTE:
• The window function only operates correctly (switching on and off), when all switching
values (including the safety zone) are greater than the minimal temperature, and
lower than the nominal temperature range.
