Safety
All safety information, notes and instructions specified in this manual must be strictly observed.
The product may only be used if all guidelines and safety instructions are adhered to.
For further information on safety, observe the instructions provided in the HIQuad X safety
manual (HI 803 209 E).
2.1
Intended Use
This chapter describes the intended use of the safety-related automation system HIQuad X.
The automation system is designed for controlling and regulating industrial process plants.
SILworX, HIMA's programming tool, is used for programming, configuring, monitoring, operating
and documenting the HIQuad X system.
2.1.1
Application in Accordance with the De-Energize to Trip Principle
The HIQuad X system is designed in accordance with the de-energize to trip principle.
If a fault occurs, a system operating in accordance with the de-energize to trip principle enters
the de-energized state to perform its safety function.
2.1.2
Application in Accordance with the Energize to Trip Principle
The HIQuad X system can also be used in applications that operate in accordance with the
energize to trip principle.
A system operating in accordance with the energize to trip principle switches on, for instance,
an actuator to perform its safety function.
When designing the automation system, the requirements specified in the application standards
must be taken into account. For instance, line monitoring (SC/OC) for inputs and outputs or
message reporting a triggered safety function may be required.
If the components are defective, the de-energized state is entered irrespective of whether the
system is operating in accordance with the energized to trip or with the de-energized to trip
principle.
2.1.3
Use in Fire Alarm Systems
The HIQuad X systems with analog inputs are tested and certified for use in fire alarm systems
in accordance with DIN EN 54-2 and NFPA 72.
The conditions of use provided in this manual must be observed, see also the HIQuad X safety
manual (HI 803 209 E).
2.1.4
Explosion Protection
The HIQuad X automation system is suitable for mounting in zone 2.
The conditions of use provided in the HIQuad X safety manual (HI 803 209 E) must be
observed.
