a latching type.
•
Over-range (flammable gases)
As soon as gas concentration exceeds 100% LEL,
MX 16 stores the over-range
condition and displays
>100% LEL. The concerned channel goes into alarm and fault
condition and OVS
(OVERSCALE) and FAULT (FAULT) visual indicators are lit.
Alarm reset is manual and under the responsability of the user who must follow the
site-specific safety guidelines. Over-range condition can only be deactivated by
switching off the detector via the maintenance menu providing the gas concentration
is below the alarm threshold.
