Changeover and monitoring module UMA710-2-…-ISO…

Changeover and monitoring module UMA710-2-...-ISO... Device features The changeover and monitoring module • Two-pole changeover of the power supply • Voltage monitoring on the preferred supply • Voltage monitoring on the redundant supply • Voltage monitoring at the automatic transfer switching device output (line 3) • Monitoring of the changeover switch for correct switching position • Monitoring of the load current to delay the changeover until the protective device has switched off the short circuit • Internal functional test, including checking the switching times • Monitoring of the insulation...

Changeover and monitoring module UMA710-2-...-ISO Other safety-enhancing measures • Continuous monitoring of all essential components and connecting wires for proper functioning • Monitoring for short-circuits at the output of the transfer switching device with defined switching behaviour • Maximum reliability when switching with: - A patented switching system with mechanical and electrical interlocking - Weld-resistant contacts with the mechanics of a circuit breaker - Insensitive to voltage fluctuations and vibrations due to stable switching position and permanent contact pressure • Preventive...

Changeover and monitoring module UMA710-2-…-ISO Bypass switch Clear text display of messages On the UMA710-2-…ISO-BP changeover and monitoring module, uninterrupted testing or repair of the ATICS® transfer switching and monitoring device can be carried out by means of the bypass switch. Please read the instructions for operation of the bypass switch in the manual. Operating, warning and fault messages are indicated in clear text display format. The required alarm indicator and test combination MK2430, MK800 or the remote alarm indicator and operator panel TM800 must be installed in a place in...
