11.1.2 Activating the gas detection system
Switch on the activation switch of the gas detection system.
Attention! When the gas detection system is activated via the main switch, the CO
2
fire suppression
device may be triggered automatically. In that case, CO
2
flows quickly from the pressurized gas cylinder
into the interior of the chamber. If the door is open, there is a risk of suffocation and frostbite.
DANGER
Risk of suffocation, poisoning, and frostbite due to triggering of the CO
2
fire
suppression device.
Death due to suffocation. Frostbite.
∅ Do NOT open the chamber door when the gas detection system is active.
Switch the main switch of the gas detection system off before opening the door of
the chamber.
• After switching the gas detection system on, wait approx. 5 minutes until the sensors are initialized
(during initialization, sensors show "Err 2")
• In the meantime, check the flow meter for measuring gas and dilution gas and adjust, if necessary.
IMPORTANT: The measuring and dilution gas must always be set to a ratio of 1:1, otherwise the CO
and H
2
sensors will malfunction. A deviation from the volumetric flow set point will result in a fault notifi-
cation and activation of the yellow indicator light (flashing signal).
• After successful initialization, the display changes to the measured gas concentration
