5 Configuration
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 inputs using the key
Value/settings Description
Changeover, phase
angle control Note:
The changeover to phase angle control mode is only possible
if the setting
r
Power controller
r
Operating mode
r
Burst-
firing mode has been made in the configuration level.
Switched off No changeover
Binary input1 Changeover is controlled by binary input1
Binary input2 Changeover is controlled by binary input2
Ext. binary input1 Changeover is controlled via an interface
Ext. binary input2 Changeover is controlled via an interface
Ext. current limiting Note:
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
r
Current limiting
r
Yes
Option 2:
Power controller
r
Operating mode
r
Pulse groups
Power controller
r
Soft start
r
Yes
Power controller
r
Current limiting
r
Yes
If, for example, "Binary input 1" is set here, when the binary in-
put is closed, instead of the current limit value set under
"Power controller
r
Current limit value" coming into effect, the
"External current limit value" (further down in the table) be-
comes effective.
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
Ext. 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.

Key lock Switched off No key lock
Binary input1 Key lock is controlled by binary input1
Binary input2 Key lock is controlled by binary input2
Ext. binary input1 Key lock is controlled via an interface
Ext. binary input2 Key lock is controlled via an interface
