Control Unit ST 20 E

Control Unit ST 20 E

The freely programmable ST 20 E control module with 4-line plain text display is used for programming, monitoring and logging of all operational states. All functions such as charge, mains and battery changeover and deep discharge protection as well as the emergency luminaires connected to the central power supply system are automatically checked. Optionally, an external phase monitor and an annunciator cover with key-operated switch can be connected by means of terminals. The test intervals for the function and duration test can be inputted. Malfunctions are shown in the display and signalled by means of potential-free contacts. An ‚E/G/A interface‘ allows connection to an overriding monitoring station.
