Gammapilot M
Endress+Hauser 13
Installation Mounting, wiring and commissioning
The mounting, wiring and commissioning of the Gammapilot M is described in the Operating Instructions
BA00236F/00/EN.
!
Note!
• When the device is being used in safety-related applications, the "Cascade in", "Cascade out" and "PT100"
terminals must not be wired (for terminal assignment, see Operating Instructions BA00236F/00/EN,
Section "Terminal assignment").
• To ensure system safety, it is recommended that safety-related and non-safety-related devices and functions
be kept strictly separate.
Orientation
Permitted orientations:
• Horizontal and at right angles to the direction of radiation (recommended due to higher sensitivity)
• Horizontal with frontal irradiation
The Gammapilot M must be positioned in the radiation path in such a way that the scintillator is completely
irradiated. The position and length of the scintillator is indicated by markings on the housing pipe.
It is permitted to use a water cooling jacket or additional coverings on the detector as protection from the sun
or weather. As additional coverings can affect the measuring signal due to backscatter, the measuring point
must not be calibrated until installation is complete.
The water cooling jacket must be filled completely during calibration. The flow values and limit temperature
values listed for water cooling in the Operating Instructions must be observed.
If several radiometric measuring points are in use, pay attention to the orientation of the sources and the
arrangement of the detectors to ensure that they do not interfere with each other.
Notes on the redundant use of multiple detectors
This section provides additional information on the use of multiple detectors in 1oo2 or 2oo3 votings for safety-
related point level detection:
• Only one radiation source may be used per measuring point.
• The following parameters must be configured identically when using multiple detectors:
Isotope, beam type, gammagraphy hold time, output damping, current date.
For background calibration as well as full and empty calibration, the same requirements that apply for single-
channel arrangement apply for each detector.
Installation with 1oo2 voting and detectors arranged one above the other:
SD230xx09
!
Note!
The position of the upper detector determines the most unfavorable switch point.
