LA Calibration

The liquid alarm sensors LA1S installed by M&C are factory activated and calibrated. If required, the
basic accuracy of the liquid alarm sensors can be optimized by recalibration. Later-installed liquid
sensors must be activated and calibrated.

To calibrate a liquid alarm sensor, proceed as follows:
1. Enter the PIN (see chapter "12.2 PIN Entry").
2. Tap and hold the

Make sure that the LA is activated. If a retrofitted LA is not activated,
the calibration has no effect and will be discarded.
-key for a short moment.
First calibrate the "dry state" of the liquid alarm sensor.
To do this, leave the LA in the dry state and enter the code "210".
Confirm the displayed value with the
Then calibrate the "wet state" of the liquid alarm sensor.
Immerse the LA in the process-dependent condensate to calibrate the
100 % wet condition via code "211". Confirm the displayed value with
the -key.
