8.7 MP Parameters
This menu allows the parameters for each sensor (MP) to be reviewed or changed. A code level 1 password is
required.

8.7.1 Activate – Deactivate MP
Every sensor needs to be active at the controller. After activation sensor signal will be displayed at the
controller. Existing alarms and faults are cleared with deactivation of the sensor.
Analog input signals are reserved for MP1 to MP3. Up to eight further Honeywell bus sensors can be
connected, here the address assignment starts with 4 and ends with 11.
Attention: The deactivated sensor does not cause a fault message.

Range
----
Set measuring range (must correspond with the sensor head).
The gas type to be monitored and the range are set in the two menus.
Ensure the controller setting is meeting the sensor setting.
Select the gas type; then the associated unit will appear on the right next to it.
The indication of measured values, alarm thresholds and hysteresis depends on the measuring range. If the
measuring range is <10, there are three, if <100, there are two, if <1000, there is one decimal place. If => 1000,
the display is without decimal place. The resolution and accuracy of the calculation is not affected by the
different measuring ranges.
Please refer to the Honeywell sensor datasheets and sensor settings for the correct range. Please refer also
the Honeywell Sensepoint XCL and Sensepoint XRL datasheet.
