Commissioning
Initial Commissioning
Power-up Sequence
After power up, the SafeZone Mini device runs through a power-up cycle.
During the power-up cycle, the seven-segment display indicates the device
status.
During the initial commissioning of an SafeZone Mini device, the following
indications are possible:
Table 12 - Seven-segment Display during and after the Power-up Sequence on Initial
Commissioning
ATTENTION: Commissioning requires a thorough check by qualified safety
personnel.
Before you operate a system that is monitored by the SafeZone™ Mini device
for the first time, make sure qualified safety personnel check and release the
system. The result of the test must be documented. Read the notes in
Chapter 1 on page 11 .
• Before the machine is released, check whether the protective devices
entirely monitor the access to the hazardous area or the hazardous point.
• After approval of the machine, at regular intervals (for example, in the
morning before the start of work) check whether the OSSDs (on the
SafeZone Mini device, a safety laser scanner that is connected or on a safety
controller) switch correctly to the OFF state as soon as there is an object in
the protective field. This test must be performed along all protective field
boundaries as per the specific regulations for the application (see
Test Notes
on page 72 ).
