Contact monitoring
Output A
EIS 1, 1 bit
DPT 1.002
C, R, T
This communication object is enabled if in parameter window A: Function
the parameter Enable function "current detection" has been selected with the option yes.
The communication object value shows the contact state when the contact is open.
Should a current flow be detected with an opening of the contact initiated via the KNX, contact
welding or manual switch on has occurred (contact fault).
The evaluation of whether a current flows occurs about one second after a contact is opened.
The current is safely detected should a measurable current (about 20 mA) flow.
A prerequisite for correct evaluation is switching via the KNX.
Telegram value
1 = contact error
0 = no current flows

Current Value
Output A
EIS10, 2 byte
DPT 7.012
C, R, T
This communication object is enabled if in parameter window A: Function
the parameter Enable function "current detection" has been selected with the option yes and in
the parameter window A: Current Detection of the 2 byte data type.
The presently detected current is sent on the KNX. 1 digit corresponds to 1 mA.

Current Value
Output A
EIS 9, 4 byte
DPT 14.019
C, R, T
This communication object is enabled if in parameter window A: Function
the parameter Enable function "current detection" has been selected with the option yes and in
the parameter window A: Current Detection of the 4 byte data type.
The current value is transferred as a mA value on the KNX.

Status Current-Threshold 1
Output A
EIS 1, 1 bit
DPT 1.002
C, R, T
This communication object is enabled if in parameter window A: Current Detection
the parameter Enable current threshold value(s) has been selected with the option yes.
The status of the current threshold 1 is only sent when a change occurs.
The status value can be inverted.
Telegram value
1 = threshold 1 plus threshold 1 hysteresis is exceeded
0 = threshold 1 minus threshold 1 hysteresis is
exceeded
