Confirmation and locking
methods
The device is configured via the operating menu (see Operating Instructions BA00270P).
When using the devices in process control safety systems, the device configuration must meet two
requirements:
• Confirmation concept:
Proven independent checking of safety-related parameters entered.
– Via increased security during parameter entry or
– Manually via a checklist
• Locking concept:
Device locked after configuration (required in accordance with IEC 61511-1 §11.6.4 and NE 79 §3).
– SIL locking via increased security during parameter entry and/or
– Hardware locking via DIP switch on electronics; software locking
Two methods are available for commissioning the devices in process control safety systems:
• Standard device configuration and hardware/software locking
• Increased security during parameter entry
Due to the increased configuration security, the use of the "Increased security during parameter
entry" method is recommended.

1) In the case of devices with firmware version ≤ 02.20.04, certain messages in the SAFETY CONFIRM. menu (increased security during parameter
entry) are automatically set from warning to alarm.
Do not use the SAFETY CONFIRM. sequence if the device is operated outside the set current or measuring range in applications, table ä 14.
2) Configuring E727 as a warning or alarm affects the SIL parameters, Table ä 4 ff.
