Fault signaling units are used in small plants where the installation of complex fault signaling systems would be too cost and labor-intensive. In the event of a fault, they enable fast fault localization of all monitoring devices and limit monitors from a central location. This increases plant availability. With the correct sensor configuration, they also provide the option of preventative maintenance.
4 fault signal inputs with LED
1 LED as centralized fault indicator
One unit each for centralized fault indication and acoustic signaling
With acknowledgment for acoustic indicators
Open-/closed-circuit principle to the 4 inputs can be adjusted via jumpers X1 - X2
A maximum of 39 5TT3 461 expansion fault signaling units can be connected to the 5TT3 460 centralized fault signaling unit
The maximum possible cable length between 5TT3 460 centralized fault signaling units and 5TT3 461 expansion fault signaling units is approx. 100 m with a conductor cross-section of 1.5 mm2.
