5.1.6 Binary inputs
2 binary inputs are provided, and an additional binary input for firing-pulse in-
hibit to which a potential-free contact can be connected.
The following functions can be triggered with binary input 1 and 2:

Value/settings Description
Ext. current limiting
This function can only be set with the following
presettings:
Possibility 1:
Controller
➔ Operating mode ➔ Phase angle control and
controller
➔ Current limitation ➔ Yes
Possibility 2:
Controller
➔ Operating mode ➔ Pulse groups
Controller
➔ Soft start ➔ yes
Controller
➔ Current limiting ➔ yes
If, for example, "Binary input 1“ is set here, the current limit
value set under "Controller
➔ Current limit value“ is overwrit-
ten when the binary input is closed and the "External current
limit value“ (further down in the table) becomes effective.
switched off No ext. current limiting
Binary input 1
External current limiting is controlled by binary input1
Binary input 2
External current limiting is controlled by binary input2
Ext. binary input1
External current limiting is controlled via an interface
Ext. binary input2
External current limiting is controlled via an interface
External current,
limit value
10% ... max. load
current +10% of the
device type
This parameter only appears if a binary input is set for external
current limitation.
The max. load current varies according to the device type.
For 20A power controllers it is possible to set 2 ... 22A.
