Gammapilot M
Endress+Hauser 17
!
Note!
• If the supply voltage for the Gammapilot M fails during the locking or unlocking procedure or during the
locking sequence, an alarm or warning is not output when the supply voltage is reapplied. For safety reasons,
however, the current output is set to error current ≤ 3.6 mA and held.
• To restart, the "safety locking (S22)" function has to be selected in the "safety settings (S2)" function group
and security locking has to be performed.
Configuration of switch point and hysteresis
The Gammapilot M converts the pulse rate linearly into the output current.
This requires configuration of switch point and hysteresis in the evaluation unit located downstream.
The following switch points must be configured in the evaluation unit:
1. 16 mA → Transition from "free" to "covered"
2. 8 mA → Transition from "covered" to "free"
SD230en13
Hysteresis to be configured in the control unit
Maintenance, recalibration Instructions for maintenance and recalibration can be found in the Operating Instructions BA00236F/00/EN.
During parameterization and maintenance work on the Gammapilot M, alternative monitoring measures must
be taken to ensure process safety.
"
Caution!
The Gammapilot M must be recalibrated in the following circumstances:
If, following calibration of the measuring point, changes to the system are made in the immediate vicinity of
the measuring point which may affect the measuring signal due to scattering, or if changes are made to the
measuring point itself which alter the radiation conditions.
A check can be carried out by verifying the pulse rate with a free radiation path and comparing it to the
calibration record, → ä 20.
