3. System description
3.1 Properties
3.1.1 Product description
The ATICS® transfer switching devices provide all functions for changeover between two independ-
ent power supplies and for monitoring unearthed power supplies. The integration of both the elec-
tronic system and the switching elements in one flat, compact device reduces space requirements
in the switchgear cabinet, minimises the amount of wiring, and reduces the fault probability. To
achieve the highest reliability, ATICS® has been developed closely in compliance with functional
safety guidelines.
Connectors at all connecting wires in combination with by-pass switches enables the ATICS® to be
tested or replaced during service works without interruption of the power supply. ATICS® consider-
ably enhances the safety level in industry and in other sensitive environments like hospitals.
3.1.2 Changeover

Automatic changeover to the second (redundant) line on loss of the preferred supply or when
the values are outside the permissible voltage range

Voltage monitoring Line 1/2 (input) and Line 3 (output)

Automatic return to the preferred line on voltage recovery

Monitoring for short-circuits at the output resp. at the distribution board downstream of the
transfer switching device avoids damaging switching operations

Manual operation, optionally locked by a padlock
3.1.3 Messages

Status indication of operating, warning and alarm messages via integrated graphic display
and external indication at MK2430/MK800/TM800 alarm indicator and operator panels

Automatic reminder for prescribed tests and service intervals

History memory for events, messages, tests and parameter changes

Exchange of information with alarm indicator and operator panels via BMS bus
3.1.4 Other functions

Continuous monitoring of all essential components and connecting wires for proper function-
ing

4 programmable relay outputs (alarm relays)

4 programmable digital inputs
