Using the EMERGENCY-STOP switch
Introduction
The EMERGENCY STOP switch is used to interrupt probe
movement and probe Air blaster cleaning immediately in the
event of danger to personnel. Actuating the switch disables all
mechanisms serving to protect the gas sampling probe.
The gas sampling probe interrupts its movement and probe Air
blaster cleaning immediately and in any position.
The probe is only retracted out of the rotary kiln after pressing
the Emergency Stop reset switch on the front of the control
cabinet.
Instructions
What to do after pressing the EMERGENCY STOP switch:
1. Remove danger only if this does not represent a subsequent
danger to the person performing the action. Please refer to
local emergency procedures if personnel need to be
medically attended. Only after this, continue with next steps.
2. Make sure that:
• the danger cannot occur again
• no-one is standing in the area of probe retractor travel
3. Unlock the EMERGENCY STOP switch by turning the back ring
in the direction of the arrow.
4. Actuate EMERGENCY Reset button

WARNING
Actuating the Service Mode switch moves the probe out of
the kiln.
• Do not stand in the area of travel of the probe buggy until
the probe has reached its end position and the warning
signal goes out.
Result:
The gas sampling probe is automatically retracted out of the kiln
and enters Manual mode of operation; the controller displays the
“manual mode” message.
Human Machine Interface (HMI)
Overview
The Human Machine Interface (HMI) is the access point for
information and control of the probe gas sampling system. The
HMI is connected directly to the control system and will show the
status of the probe gas sampling system in numbers and in
graphics. The HMI will have entry point for set points and
operational push buttons. Depending on access privileges,
various screens and options will be available.
