Connection between switch threshold and hysteresis on
(minimum safety) and
(Maximum safety):
On minimum safety the set point condition remains active so
long as the measured signal lies below the switch threshold
value plus the hysteresis
, on maximum safety larger
than the switch threshold minus the hysteresis (
Operation of the red fault LED
If the input range 4...20 mA / 20...4 mA is selected and the
actual current signal is < 3.6 mA or > 21 mA, then the red LED
on the front of the unit will illuminate.
Relay deactive (powerless), yellew LED off
Meas. value
Meas. value
* Time delay
Set up the time delay for
the set point condition
event once the switch
threshold has been
reached.
Value range:
0 to 99s
The time delay can be set in
steps of 1 sec.
