Gammapilot M
16 Endress+Hauser
Behavior of current output during locking sequence:
At the start of the locking sequence, the detector outputs the error current ≤ 3.0 mA and remains at this value
until the sequence has been run through completely and the safety-related locking procedure has been
completed by confirming the password.
The output current value must be measured during the locking procedure and confirmed in the operating
menu. The current must be measured with a accuracy of ± 0.1 mA.
Following the correct locking procedure, the Gammapilot M executes all internal diagnosis tests. During this
time, (max. 60 s), the current output is at error current ≤ 3.6 mA.
Following completion of the diagnosis phase, the present current value (4 to 20 mA) is available at the output.
If a device error is detected during diagnosis, the current signal remains in a fault state ≤ 3.6 mA.

Note!
• The lock is not cancelled if the power supply is switched off or if it fails.
• After it is locked, the detector cannot be reset using the Reset (333) function.
• If you have forgotten the password, please contact Endress+Hauser Service.
List of configuration parameters which must be confirmed
The following parameters can be configured by the user and must therefore be confirmed during the locking
procedure:
List of preconfigured parameters
The following parameters cannot be freely defined by the user.
The Gammapilot M configures them to the following initial settings by executing the locking function:
1. Background pulse rate (cps)
2. "Free" calibration point (cps)
3. "Covered" calibration point (cps)
4. Isotope (Cs or Co)
5. Beam type (standard or modulated)
6. (Gammagraphy) hold time (default value "10" for "modulated" beam type)
7. Output damping
8. Current date
9. Calibration date
1. Covered = 100 % → 20 mA
2. Free = 0 % → 4 mA
3. Output in case of alarm = 22 mA
4. Gammagraphy detection = ON
5. (Gammagraphy) Span time = 0 seconds (no dynamic monitoring)
6. Output for gammagraphy = 3.8 mA
7. Gammagraphy sensitivity = 9 (Beam type "standard"); 20 (Beam type "modulated")
8. Low output limit = OFF
9. Current output mode = standard
10. Communication address = 0
11. Service parameters = Preset values
12. Simulation = OFF
13. Release code = SIL locked
