Description Of The Switching Functions - turck TS400/500 Série Mode D'emploi

7 Description of the various switching functions
Hysteresis:
This function ensures a stable switching
status, independent of the system-in-
herent temperature fl uctuations and the
adjusted set point.
The switching range is defi ned by the
user via a switching point (SP) and a
release position (rP).
Window:
With this function a range is determined
in which the switch assumes a defi ned
switching status.
The switching range is defi ned by the
user via an upper window limt (SP) and
a low window limit (rP).
The minimum hysteresis between SP and rP is approx. 0.2 K.
If the applied temperture is above or below the customer defi ned limits,
the display starts fl ashing. If the applied temperature is 0.3 % outside
the specifi ed measuring range, the display will indicate UL at the lower
range limit and OL at the upper range limit. The display will indicate Err
it the probe is faulty (short-circuit or wire break).
