... Basic safety rules
Operator's obligations towards personnel
The operator must ensure:
• that personnel meet the requirements for their tasks.
• that personnel are provided with the personal safety
equipment specified in these operating instructions and, if
necessary, additional safety equipment against risks posed
by the installation site, e.g. by noise.
• that personnel are provided with maintenance equipment in
order to secure the service switch, e.g. padlocks.
• that the system has protection against restarting the power
supply in order to ensure that the system is powered off
when the main switch is switched off to prevent
unauthorized activation of the power supply.
• that personnel have read and understood these operating
instructions before they handle the probe gas sampling
system.
• that personnel are regularly and recurrently instructed about
the risks and safety measures when handling the probe gas
sampling system.
• that the work areas of the probe gas sampling system are
adequately aired and illuminated.
• that the safety regulations in force in your country are
observed.
• that the safety regulations pertaining to setting up and
operating electrical equipment in force in your country are
observed.
• that the safety regulations pertaining to handing gases,
lubricants, etc. in force in your country are observed.
Procedure in the event of accidents
The probe gas sampling system is designed and built in such a
way that personnel can work with it without any risk. Despite all
precautions, however, unforeseeable accidents may nevertheless
occur in unfavourable circumstances. If cooling water tubes or
compressed-air tubes burst, shut down the probe gas sampling
system and secure it against being switched on again.
If errors are detected, shut down the system and secure it
against being switched on again. Before approaching the probe
gas sampling system, wait until the entire cooling water or the
entire compressed-air has been evacuated. If the switched-on
probe gas sampling system poses a danger, proceed as follows:
Aim
Stop movement of the system
Disconnect the system from the main
and UPS power supplies
Evacuate the compressed-air system
If risk-free operation is no longer possible
If it can be assumed that safe operation is no longer possible,
the probe gas sampling system must be taken out of operation
and secured against being started up again. It can be assumed
that safe operation is no longer possible:
• If the probe gas sampling system is visibly seriously
damaged
• If the probe gas sampling system no longer works
• After prolonged storage under adverse conditions
• After severe transport stress

Action
Press the EMERGENCY-STOP switch
Note: The probe interrupts its
movement immediately and in any

out of the rotary kiln after turning the
service switch to service mode,
releasing the EMERGENCY-STOP
switch, and operating the probe
retractor in manual.
Turn off the main and UPS power
switch on the side of the control
cabinet.
Turn off the safety breaker on the door
of the Retractor rear panel to prevent
all movement of the probe.
Close the MAIN VALVE on the retractor
unit or at the source outlet from the air
tank (if available)
