Gasman Alarm indications
17
In the event of a Flammable overange alarm
If flammable gas concentrations exceed 100% LEL Gasman
locks into alarm and displays ‘9999’ showing an overange
condition. Gasman will temporarily cut off power to the
sensor to prevent burn out and display a progress bar for 200 seconds.
When the timeout is complete, either press the button to continue or
switch your unit off and on to restart. This option is programmable with
Crowcon Portables PC software and the default is switched on.
If the Gasman goes over range at any time it is recommended to carry out
a gas test before using it again.
