6.3.12. Parameter -12- : Locking of keyboard operation
The parameters of the main menu, e.g.: target power factor, switching time, etc. and the manual
operating mode MAN, can be protected against unauthorized adjustment by locking the keyboard.
Locking is activated, when the display indicates

locked
YES
If RST is selected (see page 20), NO is reset.
6.3.13. Parameter -13- : Functioning of the alarm relay
During normal and trouble-free operation, the alarm relay is operative. The contact is open. In case of
faults and of a breakdown of the supply voltage, the contact closes. The fault situation to which the
alarm relay shall react can be selected by means of parameter 13.

X = Alarm relay reacts to this fault situation.
The different types of fault are described in the survey matrix under item 7.
If RST is selected (see page 20), 0 is reset.
6.3.14. Parameter -14- : Switching out the capacitor steps in case of alarm
Capacitor steps can be switched out when certain alarm signals are given. The fault alarm which shall
cause a switch-out can be selected by means of parameter 14. The specific kind of fault alarm
determines the switch-out behavior. The numbers 1- 3 indicate the priorities.
1 = the capacitor steps will be switched out immediately without time delay.
2 = the capacitor steps will be switched out after a time delay which can be modified (parameter 19)
3 = steps will continue being switched out until the fault alarm has disappeared.
