5.1.2 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 pressure 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 (lower switching value minus three times the
increment, see point 5.4). The upper switch-back value is just above the upper switching
value (upper switching value plus three times the increment, see point 5.4). The area between
switching value and switch-back value forms a safety zone which prevents unwanted
switching operations from occurring (e.g. triggered by pulsations from a pump).
Example for switching output 1 (normally open function):
Abbreviations:
“HI 1”, “HI 2” = High level 1 or 2 = upper switching value 1 or 2
“Lo 1”, “Lo 2” = Low level 1 or 2 = lower switching value 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 0 psi and lower than the nominal pressure range.
5.2 Analog output
Analog output signal:
4 to 20 mA or 0 to 10 V (can be set in the menu “basic settings”)
5.3 Setting the switching points, hysteresis and/or
switching values for the window function
• Press “mode” key
• “S.P.1” or “Hi.1” is displayed
• Keep pressing the “mode” key until the required parameter is displayed (for pre-set
switching point function: “S.P.1”, “hYS.1”, “S.P.2”, “hYS.2” appears; for pre-set window
function (WIN) “Hi.1”, “Lo.1”, “Hi.2”, or “Lo.2” is shown)
• After 2 seconds the actual setting flashes.
• Use the
or
the keys to alter the setting.
