Value of hysteresis current
threshold 1

Options:

3/25/50

/100/200/500 mA

1/2/5 A

To avoid a continuously changing threshold value state, the current detection thresholds feature a
hysteresis function. The set

Value of hysteresis current threshold

ensures that a current change is

only registered as such if it is greater than the hysteresis value. Only then will a change of current
threshold value status be sent.

Partly due to fluctuations in the electrical system and the detection accuracy of the current

transformers in the Switch Actuator, 3 mA is the smallest hysteresis possible.

For further information see:

function with current detection

, p. 142 and

Current detection

specifications

, p. 44

Please note

No hysteresis is used with the option none. With a highly fluctuating current value this can often
lead to frequently changing threshold results. The bus load increases unnecessarily if there is
continuous status change.

Current threshold 1

+/- hysteresis

Options:

no sending
send "0" at crossing over
send "1" at crossing over
send "1" at crossing lower
send "0" at crossing lower
send "0" at crossing over – "1" at crossing lower
send "1" at crossing over – "0" at crossing lower

This parameter determines the value of the communication object

Status Current-Threshold 1

when

undershooting or overshooting current threshold value 1.

•

no sending:

no telegram is sent when there is a current threshold value overshoot or

undershoot

•

send "0" at crossing over:

Should current threshold value 1 be overshot, communication object

Status Current-Threshold 1

sends

the value 0. An undershoot sets the value to 1 but no

telegram is sent.

•

send "1" at crossing over

: Should current threshold value 1 be overshot, communication object

Status Current-Threshold 1

sends

the value 1. An undershoot sets the value to 0 but no

telegram is sent.

•

send "0" when crossing lower

: Should current threshold value 1 be undershot, communication

object

Status Current-Threshold 1

sends the value 0. An overshoot sets the value to 1 but no

telegram is sent.
