Preparation
Running-in time and warm-up time
Procedure
1
Open the VISIC100SF enclosure:
▸
Unscrew the two screws on the enclosure cover with the SW4 hex key.
▸
Remove the enclosure cover on the front side of the device.
▸
Unscrew the four screws of the measuring unit.
▸
Hang the measuring unit in using the hinge fixture and swivel it downwards.
2
Set the VISIC100SF to Maintenance mode.
3
Observe the running-in and warm-up time for the gas sensors.
NOTICE:
Risk of destruction of electronic components by electrostatic discharge (ESD)
When touching electronic assemblies, there is a risk of the assembly being destroyed by
electrical equipotential bonding.
▸
Make sure you have the same electric potential as the subassembly (e.g. by
grounding) before touching the subassembly.
NOTICE:
Entering a too high test gas concentration on the adjustment tool can lead to incorrect
adjustment of the electrochemical cell.
▸
Ensure the correct test gas concentration is used depending on the gas
concentration,
NOTICE:
The warm-up phase for the gas sensors takes 5 minutes.
▸
Do not interrupt the connection to the gas sensors or the voltage supply of the
VISIC100SF when opening it.
The 5-minute warm-up phase of the gas sensors will otherwise restart.
