Rise of opacity higher than damage check level
- Display "CODE" : -215 (-116) (-115)
representing the type of device VN 215, VN 116 or VN 115
- Display "VALUE" : Value is higher than zero and represents the opacity
- LED - Chain with increasing opacity the illuminated LED is moving
upwards
- LED "READY": on
- LED "TEST": off
- LED "ALARM": off
- Devices VN 215 / 93 and VN 116 / 93 only : The valves in the valve box will be
activated according to a special algorithm to identify the side of the engine with the
highest opacity (on VN 116 / 93) or the compartment with the highest opacity on
devices VN 215 / 93
Rise of opacity higher than main alarm level
- Display "CODE" : -215 (-116) (-115)
representing the type of device VN 215, VN 116 or VN 115
- Display "VALUE" : On devices VN 116 / 93 and VN 215 / 93 :
represents the opacity in the compartment which is
indicated by the red symbol of the valve box
On devices VN 115 / 93 : Average value of the opacity of all
compartments.
- LED - Chain with increasing opacity the illuminated LED is moving
upwards
- LED "READY": on
- LED "TEST": off
- LED "ALARM": on
- ALARM - Relay will be activated
- VN 116 / 93 :
The side of the engine (left or right) where the highest opacity occurred will be
indicated by 3 red symbols shown above each other on the valve box.
It can be assumed that the engine damage is located on that side.
- VN 215 / 93 :
