 Before commencing any work on the gas sampling system, turn the ser-
vice switch to ON and secure the service switch against unauthorized
switching (with a padlock).
 Additionally press the EMERGENCY-STOP switch before working on the
retractor or probe.
 Do not enter the danger area around the retractor until it is at standstill
and the warning lamps and buzzer are off.
 Never stand in the danger area around the retractor when the protective

 When the warning lamps light up or the earning buzzer buzzes, leave the
danger area around the probe retractor immediately as the probe is
about to move at any moment.
 Press the EMERGENCY-STOP switch immediately if anyone is still in the
danger area around the retractor after the warning lamps light up or the
warning buzzer buzzes.

expected, wait for the warning lamps on the retractor terminal box to go out
before fixing the errors.
