2.3.2 Controller and I/O
Emergency Shut-down
An emergency stop should always be available. Adapt it to local statutory regulations. This is an
obligation of those responsible for the plant design and construction. The controller system does
not supply this specially arranged function.
NOTE
Check the location of the emergency stop and use it in an emergency
situation.
From an electrical and functional viewpoint, an emergency stop has the same consequences to
the controller and attached equipment as a safety shut-down. See below.
Safety Shut-down
The controller and its S100 I/O mounted in a row of joined cabinets are, from the mains power
supply viewpoint, an entity. Safety shut-down aimed at disconnecting the controller from the
mains is carried out in two ways:
•
As prescribed in the site planning section,
Section 2.1.7, Power Supply and Fusing
should be a common safety switch installed within 3 m from the cabinets.
NOTE
Check the location of the safety switch and use it when working with the
equipment.
The safety switch should shut down the power supply of not only the electronics system
but also the adequate transducers and other process objects. In other words, a total power
shut-down for the plant section controlled.
Since the safety switch is a plant component, this document cannot stipulate and describe
the design exactly. Please check the plant documentation in this respect carefully.
Instructions indicating the extent of the power supply shut-down should be attached to the
safety switch.
•
You can also create a selective power shut-down of the entire electronics system using the
mains circuit breaker in the lower part of the cabinet where the controller subrack resides.
The breaker is labeled S1.
This circuit breaker sometimes also disconnects the field equipment supply for the plant.
NOTE
Sometimes exist several breakers. See
