5.8 Preselection 1 Menu
This function is only available for devices with option CO, AO or RL.
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
RESULT=0
Display value is zero (Standstill after STANDSTILL TIME(s)),
e. g. standstill monitoring, (only in mode SPEED and PROCESS TIME).
7
RESULT>= PRES->0
Auto reset at PRESELECTION 1: (only in mode TIMER or COUNTER)
Display value is greater or equal PRESELECTION 1, the display value is set to zero.
If the BACH MOD is active, the batch counter increments or decrements when the
display value is set to zero.
8
RESULT<= 0->SET
Auto set to PRESELECTION 1: (only in mode TIMER or COUNTER)
Display value is less or equal zero, the display value is set to PRESELECTION 1
If the BACH MOD is active, the batch counter increments or decrements when the
display value is set to PRESELECTION 1.
9
RES>=PRES-TRAIL
Trailing PRESELECTION 1:
Display value is greater or equal PRESELECTION 2 – PRESELECTION 1  ON,
PRESELECTION 1 is the trailing value from PRESELECTION 2
