5.1.6 Binary inputs
There are 2 binary inputs and one additional binary input for firing-pulse inhibit
available, to which a potential-free contact can be connected.
The following functions can be triggered with binary input 1 and 2:
h
Switch to the configuration level
r
Binary input using the key
Value / settings Description
Ext. current limiting This function can only be set if the following
presettings have been made:
Option 1:
Power controller
r
Operating mode r Phase angle control and
Power controller rCurrent limiting rYes
Option 2:
Power controller

Current limiting
r
Yes
If, for example, "Binary input 1" is set here, when the binary in-
put is closed, the current limit value set under "Power control-
ler
r
Current limit value" is overwritten and the "External
current limit value" (further down in the table) becomes effec-
tive.
Switched off No ext. current limiting
Binary input1 Ext. current limiting is controlled by binary input1
Binary input2 Ext. current limiting is controlled by binary input2
Ext. binary input1 Ext. current limiting is controlled via an interface
Ext. binary input2 Ext. current limiting is controlled via an interface
External current
limit value 10 % to max. load
current of the
device +10 % Note:
This parameter is only available if a binary input is set for ext.
current limiting.
The max. load current varies depending on the device type.
For 20 A power controllers, 2 to 22 A can be set.
