Manual, 05/2019, L1V30538268002A-01
Note
Further procedure in manual mode
In manual mode a dialog opens for selection of the source. For further information, please
refer to chapter Manual mode (Page 140).
8.1.2
OFF mode (OFF)
In this mode the device is disabled and performs no actions. All displays, both of the
measurements and status LEDs, remain active. If the transfer control devices are pulse
controlled, both Open and Close controllers remain disabled in the OFF mode. In the case of
continuous signal control, on the other hand, the behavior can be selected by means of
Parameter P07.n.06.
To call up programming menus, you must always switch to the OFF mode first.
8.1.3
TEST mode
Press the TEST key for
≥
5 seconds to initiate failure of the priority source. The simulation
involves considering a two-minute absence of the priority source, even if it is actually
present. For more information, refer to chapter Simulation of the failure of the priority source
(Page 69).
8.1.4
Manual mode (MAN)
In manual mode the switching devices can be controlled manually. This enables the user to
switch freely between the power sources.
