2.3.1
Step-by-step design
With respect to the due care to be applied in designing and implementing the
hardware and software of the control parts realised with the PROTECT-PSC
system there are no differences by comparison with the traditional state of the art,
i.e. errors and inadequacies in design and implementation can impair the intended
protective functions in the same way.
Step 1:
Risk analysis in accordance with EC Machine Directive or ISO 12100-1 and ISO
12100-2 as well as the determination of the (graded) protective measures
(protective devices, additional precautionary measures, categories).
Step 2:
Planning or design of the PROTECT-PSC stations needed.
Step 3:
Planning or design of the safety relationships between these safety-oriented inputs
and outputs under consideration of the desired interdisciplinary and/or partial
dependencies and non-dependencies, possibly under additional consideration of
different operating modes etc.
Step 4:
Assembly and wiring of the PROTECT-PSC stations.
Step 5:
Checking of correct cabling.
Step 6:
Parameter assignment of the PROTECT-PSC system. Refer to chapter 6 in this
respect.
Step 7:
Reverse analysis of parameter assignment. Refer to chapter 6.13.2 in this respect.
The reverse analysis described in chapter 6.13.2 cannot replace a check of the
wiring and in particular of the correct wiring of the outputs.
Step 8:
Initialisation of the PROTECT-PSC system. Before initialising the PROTECT-PSC
system we recommend the temporary connection of the mobile emergency off
(emergency stop) control device between mains supply and mains isolation device
in order to be able to control any undesirable reactions in the safety circuit resulting
from faulty wiring and/or parameter assignments.
Step 9:
Random checking of desired safety-oriented functionalities. It is not necessary to
perform a complete acceptance test of the stipulations in step 3 for the PROTECT-
PSC system due to the reverse analysis already performed in step 7.
