3 Product Description
X-MIO 7/6 01 is a overspeed trip module intended for use in the programmable electronic
system (PES) HIMax.
The module serves for monitoring the rotation speed and the shut down (trip function) of a
turbine. The module is equipped with the following inputs and outputs:
Inputs/outputs Number Task
Safety-related
measuring inputs 3 Rotation speed measurement (frequency) 0...35 kHz,
Safety-related
rotation sense inputs 3 Reading in static rotation sense signals
Safety-related
digital input 1 External reset input, turbine start, reset after
shut down (trip function)
Safety-related
digital inputs
3
Trip signals from external protection devices such as
machine monitoring systems
Safety-related
digital outputs 5 Actuator control, e.g., solenoid valves
Relay output
(non-safety-related) 1 Potential-free signaling contact (changeover),
warning relay
Table 3: Module Inputs and Outputs
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.
The module can be used to realize applications in accordance with API 670. The module
complies with the turbine requirements for rotation speed monitoring and trip routines defined in
API 670. The rotation speed monitoring and the trip routines are independent of the overall
HIMax system and the user program.
The trip function complies with the requirements specified in the Machinery Directive.
The module has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511 and IEC 62061) as well as Cat. 4 and PL e (EN ISO 13849-1).
Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards used to
test and certify the module and the HIMax system.
The module is inserted in redundant connector boards to increase availability through module
redundancy. To this end, the base plate must be equipped with at least two adjacent slots.
The module can be inserted into any of the base plate slots with the exception of the slots
reserved for system bus modules. For more information, refer to the System Manual
(HI 801 001 E).
