Continuation „Preselection 1 Menu“:
The totalization depends on the operation mode. See chart in chapter IN 1 Totalization.
MODE 1
Switching conditions for preselection 1. Output/ relay/ display switches under the following conditions:
0
|RESULT|>=|PRES|
Absolute value of the display value is greater or equal absolute value of
PRESELECTION 1
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value >= PRESELECTION 1  ON,
Display value < PRESELECTION 1 – HYSTERESIS 1 OFF
1
|RESULT|<=|PRES|
Absolute value of the display value is less or equal absolute value of
PRESELECTION 1 (start-up suppression (START UP DELAY) is advisable)
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value <= PRESELECTION 1  ON,
Display value > PRESELECTION 1 + HYSTERESIS 1 OFF
2
|RESULT|=|PRES|
Absolute value of the display value is equal absolute value of PRESELECTION 1
A range (Preselection +/- ½ Hysteresis) can be defined and monitored in
conjunction with the hysteresis.
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value > PRESELECTION 1 + ½ HYSTERESIS 1  OFF,
Display value < PRESELECTION 1 - ½ HYSTERESIS 1  OFF
3
RESULT>=PRES
Display value is greater or equal PRESELECTION 1, e.g. overspeed
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value >= PRESELECTION 1  ON,
Display value < PRESELECTION 1 – HYSTERESIS 1 OFF
4
RESULT<=PRES
Display value is less or equal PRESELECTION 1, e.g. underspeed
(start-up suppression (START UP DELAY) is advisable)
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value <= PRESELECTION 1  ON,
Display value > PRESELECTION 1 + HYSTERESIS 1 OFF
5
RESULT=PRES
Display value is equal PRESELECTION 1. A range (Preselection +/- ½ Hysteresis)
can be defined and monitored in conjunction with the hysteresis.
With HYSTERESIS 1 not equal 0 the following switching condition is applied:
Display value > PRESELECTION 1 + ½ HYSTERESIS 1  OFF,
Display value < PRESELECTION 1 - ½ HYSTERESIS 1  OFF
6
RES>=PRES-TRAIL
Trailing PRESELECTION 1:
Display value is greater or equal PRESELECTION 2 – PRESELECTION 1,
PRESELECTION 1 is the trailing preselection from PRESELECTION 2.
HYSTERESIS 1
This parameter defines the switching hysteresis of the switch-off point for preselection 1
0
No switching hysteresis
…
99999
Switching hysteresis of 99999
