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 (Presel/- 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 (Presel/- 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.
