Product Description

X-MIO 7/6 01 is a overspeed trip module intended for use in the programmable electronic

system (PES) HIMax.

Only sensors (pulse generators) either providing pulses or pulses with a static rotation sense

may be connected to the measuring inputs. HIMA recommends using sensors of the same type

to reduce divergence among the measured values to the greatest extent possible.

The module monitors the rotation speed and, optionally, the acceleration of a turbine with

respect to configurable thresholds. It also shuts down the turbine through the trip function when

the thresholds are violated, see Chapter 4.4.2 and Chapter 4.4.3.

The trip function is implemented in the module’s operating system. It operates therefore

interference-free and independently of the HIMax overall system and the user program. The trip

function is triggered within the module cycle if the evaluation of the measuring or digital inputs

results in a trip condition, see Chapter 4.4.4.
