Operation Instructions
BotOn/BotOff/TopOn/TopOff
These parameters represent the switching threshold for 2-point and 4-point switching modes.
The switching thresholds must not exceed the measuring range.
These parameters represent the switching threshold for 2-point switching modes:
Selection Mode Switching point Range
BotOff Under/NInv G 0…f
max
TopOn Under/NInv G * (1 + H[%]/100 %) < f
max
BotOn Over/NInv G * (1 - H[%]/100 %) 0…f
max
TopOff Over/NInv G < f
max
BotOn Under/Inv G 0…f
max
TopOff Under/Inv G * (1 + H[%]/100 %) < f
max
BotOff Over/Inv G * (1 - H[%]/100 %) 0…f
max
TopOn Over/Inv G < f
max
These parameters represent the switching threshold for 4-point switching modes:
Selection Mode Switching point Range
BotOff NInv G * (1 - 1.2 * H[%]/100%) > 0
BotOn NInv G * (1 - H[%]/100%)
TopOn NInv G * (1 + H[%]/100%)
TopOff NInv G * (1 + 1.2 * H[%]/100%) 0…f
max
BotOn Inv G * (1 - 1.2 * H[%]/100%) > 0
BotOff Inv G * (1 - H[%]/100%)
TopOff Inv G * (1 + H[%]/100%)
TopOn Inv G * (1 + 1.2 * H[%]/100%) < f

Locking function
This parameter depends on the physical state of the relay. Parameter “Inversion” is regarded.
Selection Description
Switched on The relay switches on according to the measured value and selected
configuration. It stays permanently locked on.
The locked state is left after power on reset or detection of a failure.
Switched off The relay switches off according to the measured value and selected
configuration. It stays permanently locked off.
The locked state is left after power on reset.
Switching on/off delay
The value of this parameter specifies the switch on/off delay after detection of of switch on/off
condition.
Values between 0.05…75 s are possible.
Selection Description (Ex, NEx)
On delay The value of this parameter speci-
fies the switch on delay after detec-
tion of switch on condition. 0.0, 0.5, 0.75, 1.0 s
Off delay The value of this parameter speci-
fies the switch off delay after detec-
tion of switch on condition. 0.0, 0.5, 0.75, 1.0 s
