Cerabar M, Deltabar M, Deltapilot M / 4...20 mA HART Operation
Endress+Hauser 39
5.2 Operation without operating menu
5.2.1 Position of operating elements
The operating keys and DIP switches are located on the electronic insert in the device.
Function of the DIP switches
P01-Mxxxxxxx-19-xx-xx-xx-001
Fig. 25: HART electronic insert
1 DIP switch for locking/unlocking parameters relevant to the measured value
2 DIP switch for switching damping on/off
3 DIP switch for alarm current SW / Alarm Min (3.6 mA)
4 DIP switch only for Deltabar M:
Switch 4: "SW/Square root"; used to control the output characteristics
Switch 5: "SW/P2-High"; used to determine the high-pressure side
5 Slot for optional local display
6 Green LED to indicate successful operation
7 Operating keys for lower range value (zero) and upper range value (span)

2damping Damping is switched off.
The output signal follows measured value
changes without any delay.
Damping is switched on.
The output signal follows measured value
changes with the delay time .

3 SW/Alarm min The alarm current is defined by the setting in
the operating menu.
("Setup" -> "Extended setup" ->
"Curr. output" -> "Output fail mode")
The alarm current is 3.6 mA regardless of
the setting in the operating menu.
The following switches only for Deltabar M:
4SW/ The output characteristics is defined by the
setting in the operating menu.
•"Setup" -> "Measuring mode"
• "Setup" -> "Extended Setup" -> "Current
output" -> "Linear/Sqroot"
The measuring mode is "flow" and the
output characterisitcs is "Square root"
regardless of the settings in the operating
menu.
