5 Configuration
5.1.7 Binary inputs
There are two digital inputs and an additional digital input for firing pulse inhibit
available to which a PLC level can be applied.
The following functions can be triggered with digital input 1 and 2:
h
Switch to the configuration level
r
Binary inputs using the key
Value / settings Description
External change-
over of setpoint
specification Switched off No external changeover of setpoint specification
Digital input1 Changeover is controlled by digital input1
Digital input2 Changeover is controlled by digital input2
Ext. digital input1 Changeover is controlled via an interface
Ext. digital input2 Changeover is controlled via an interface
Setpoint specifica-
tion for changeover Voltage input Selects the source that is used to specify the setpoint value
when external changeover of the setpoint specification is acti-
vated.
Note:
The only analog inputs that are available here are those that
have not yet been populated by a setpoint specification, for
example.
Current input
Value, adjustable
Setpoint value for
changeover 0 % to 100 % Note:
This parameter is available only if "Value, adjustable" is se-
lected for setpoint specification for changeover.
Keypad
locking Switched off No key lock
Digital input1 Key lock is controlled by digital input1
Digital input2 Key lock is controlled by digital input2
Ext. digital input1 Key lock is controlled via an interface
Ext. digital input2 Key lock is controlled via an interface
External switch-off
of display lighting
Switched off
No external switch-off, i.e. the background lighting
behaves according to the configuration in Chapter 5.1.1
Digital input1 Switch-off is controlled by digital input1
Digital input2 Switch-off is controlled by digital input2
Ext. digital input1 Switch-off is controlled via an interface
Ext. digital input2 Switch-off is controlled via an interface
Inhibit input
control direction The firing pulse inhibit can be triggered in the event of "high or
low switching level".

"high load ON" Per default:
Inhibit input "high", power controller does not supply power.
Inhibit input "low", power controller supplies power.
"high load OFF"

digital input1 high inactive The function for digital input 1 can be triggered for "high or low
switching level".
