• Temperature monitoring
Temperature monitoring by a rod controller (bimetal switch) is used to detect a temperature increase
due to thermal run-through or fire. As soon as the threshold value of 120 °C is exceeded, message level
2 is triggered directly and the CO
2
fire suppression system is activated.
The adjustable safety controller class 2 and optional safety devices class 2 remain functional and offer
additional protection against excessive temperatures for the chamber.
• Gas detection (chap. 7.8)
• Alarms
Alarm via indicator light and buzzer with forwarding of notifications and alarms to customer systems
(chap. 13.1), notification and alarm messages on the MB2 controller (chap. 13.2)
• CO
2
fire suppression device (chap. 7.9)
• Mechanical door lock (chap. 7.10)
• Exhaust port with reversible pressure relief flap (chap. 7.11)
• Interior spark protection
Partition disks between the fan and rear wall and between the fan and suction element are used to
prevent sparks on moving surfaces.
• Inertization connections for customer systems (chap. 9.2)
Further measures to prevent accidents
• Indications on the type plate
See operating manual chap. 1.6.
• Operating manual
An operating manual is available for each chamber.
• Overtemperature monitoring
The chamber is equipped with a temperature display, which can be read from outs.
The chamber is equipped with an additional safety controller (temperature safety device class 2 acc. to
DIN 12880:2007). Visual and audible (buzzer) signals indicate temperature exceeding.
• Safety, measurement, and control equipment
The safety, measuring, and control equipment is easily accessible.
• Electrostatic charge
The interior parts are grounded.
• Non-ionizing radiation
Non-ionizing radiation is not intentionally produced, but released only for technical reasons by electrical
equipment (e.g. electric motors, power cables, solenoids). The machine has no permanent magnets. If
persons with active implants (e.g. pacemakers, defibrillators) keep a safe distance (distance of field
source to implant) of 30 cm, an influence of these implants can be excluded with high probability.
• Protection against touchable surfaces
Tested according to EN ISO 13732-1:2008.
• Floors
See operating manual chap. 8.4 for correct installation
• Cleaning
See operating manual chap. 28.4.
