The Harmony XPS Universal safety relays are characterized by their functional scope and diagnostic ability, which reduces downtime in the event of an error. This safety component includes a safe still detection of an engine by measuring the residual voltage, so that no other sensors need to be installed. For this purpose, the engine line is connected to the standstill guard and after the engine is switched off the voltage induced by the running rotation. If the measured residual voltage is below the front-side set limit value (50- 500 mV), an engine stop is assumed. In addition, a delay of 0.5 to 60 seconds is also adjustable on the front side. DC and AC engines can be monitored for engine standstill in 1 or 3-phase networks up to 690 V. This safety switch has 1 secure relay close contact at the output, 1 semiconductor message output and 1 diagnostic signal. With the help of the qualified diagnosis, states and errors are detected and transmitted by direct wiring to a standard input of a PLC by means of a telegram. A prefabricated function component for common control systems evaluates these messages so that the operator is fully informed at the machine display. If the number of outputs is to be increased, the XPSUEP14AC extension can be easily connected to the side via an integrated connector and the cross-wiring is not time-saving. The supply voltage is 24 VAC / DC and the connections are made via removable spring-train terminals. Application up to safety level PL e in category 3 or SIL3 can be implemented. Multifaceted authorisations allow for international use. The assembly is done by fastening to a hat rail or by screwdriver on mounting plates. To protect the settings under the transparent cover, a clearly numbered locking tape is attached.
