6 Operation
6.1 Environmental conditions
The lifetime of the catalytic cartridge depends on the operating environment related to certain
pollutants.
Take care to avoid exposures to some vapours products as silicone (vapours of some paintings,
some seals ...), halogenated products (molecules containing one atom of chlorine, fluorine,
bromine) or as sulphur ones (H2S...).
6.2 Inhibition
Maintenance Inhibition is temporary. It appears during power up and maintenance phases.
Inhibition stops automatically when the operator gets out of the maintenance menus or 10 minutes
after the end of communication with the TLU.
Maintenance inhibition can be configured in "frozen" mode (Factory setting) or in "free" mode
with the TLU or TLH700. It cannot be configured by the magnetic wand.
•
In "frozen" mode, outputs (current and relay) remain in their previous state.
For example, if the device indicated a fault, this state would be maintained during the
inhibition.
•
If the unit is configured in "free" inhibition mode, the output current will be on the same
level as for the permanent inhibition
The permanent inhibition is activated by an order issued by the TLU, the TLH700 or the magnetic
wand when an operation is performed at or around the device, or when the operator wants to
inhibit a faulty device. The permanent inhibition must be removed by an operator’s deliberate
action using the TLU, the TLH700 or the magnetic wand.
As for the maintenance inhibition, this special mode is leading to a purple colour
on the display.
