Commissioning Gammapilot FMG50

The failure current behavior can be defined as a min or max alarm.
• Min alarm is defined with <3.6 mA
• Max alarm is defined with >21.5 mA
• Both alarm conditions are guaranteed over the entire temperature range and under
the influence of EMC interferences
• If max alarm current has been selected as the failure current, the current value can
be adjusted between 21.5 to 23 V
The setting is made via the operating menu:
Application -> Current output -> Failure current
• In the case of the min alarm settings, there may not be sufficient energy to power
the display lighting and the Bluetooth function. To guarantee the measurement
function, the display lighting/Bluetooth functions may be disabled and enabled
again once sufficient power is available.
The calibration of the Gammapilot FMG50 is completed.
7.2.5 Slave mode
The slave mode can be used if the measured raw pulse rate is to be processed by a
downstream evaluation unit (e.g. a controller) and not by the Gammapilot FMG50.
In this operating mode, the Gammapilot FMG50 transmits the raw pulse rate in cnt/
125 ms as the primary value.
No other settings must be made once the "Slave mode" has been selected. Commissioning is
concluded immediately.

The current output is automatically assigned linearly:
• 4 mA = 0 cnt/125 ms
• 20 mA = 1000 cnt/125 ms
The use of a gamma modulator FHG65 cannot be configured in the "Slave" operating
mode.
If the use of a gamma modulator FHG65 is required, please contact Endress+Hauser
Service.
