10 HMI local indicator
10.8.1 Detailed diagnostic info from HMI
When the above kind of diagnostic information is displayed,
from the HMI it is also possible to see the details.
10.9 Activation procedure
— Press the (1) key for 4 seconds until a special symbol
appears in the low left corner of the display
Important. This step is necessary only for the keypad activation of
TTG HMI type. For conventional HMI start from step 2.
— Press the key (2)
— The HMI enter in the special menu with three items:
Diagnostics
Operator View 1
Signals View
— Select “Diagnostics” and the list of all the active error
conditions appears with on top the worst condition.
The format of how the detailed diagnostic info are displayed is
“XA.BBB” where:
X = NAMUR
NE107 Categories A = Priority. (Higher
number = higher priority)
BBB = error code
F = Failure
M = Maintenance
O = Out of
Specification
C = Function
Check
Important. The list and details of the possible HMI error code are
described in the Appendix A – Device Data Block (Diagnostic,
Block_err and Status Byte).
10.10 HMI as Feedback of the local push button
operations
As consequence of the operations described in the apposite
section, when the Z or S buttons are released, the feedback of
the executed operation is displayed in the bottom of the LCD
(same position as per diagnostic messages):
Message Description
! Oper Done
The push button operation has been successfully
executed
! Proc Too Low
The Pressure measured in input is too low and not
acceptable for the requested operation
! Proc Too High
The Pressure measured in input is too high and not
acceptable for the requested operation
! New URV Error
The Zero (Z) operation cannot be accepted because
the URV would be shifted outside the Upper Sensor
limit
! Span Error
The Span (S) operation cannot be accepted because
the new URV would be too close to the LRV and their
difference lower than the Minimum Span value
! Oper Disabled
The push button operation has been refused because
the Write Protection is enabled with the hardware
button or in
PB_WRITE_LOCKING or because the
Local Operation is disabled in the
PB_LOCAL_OP_ENA
10.11 HMI as configuration tool
The HMI can be used to read and change the display
configuration through a dedicated menu accessible by using
the 4 HMI buttons. To access the functionality of the HMI an
activation procedure needs to be carried out.
For details see APPENDIX B - HMI menu Structure
10.12 LCD (L1 option) Activation considerations.
Gain access to the display by unscrewing the windowed cover.
Please observe the Hazardous area prescription before
proceeding with the cover removal. For activation, see
instructions below.
10.13 TTG (L5 option) Activation considerations.
The TTG technology allows the user to activate the keypad on
the HMI without the need of opening the windowed cover of
the transmitter. The capacitive pick-ups will detect the
presence of your finger in front of the respective button
activating the specific command. At the transmitter power-on
the HMI automatically calibrate its sensitivity, it is mandatory for
the proper functioning of the TTG HMI that the cover is properly
tightened at power-on. In case the cover has been removed to
access the communication board, it is recommended to power
off and power-on again the transmitter once the windowed
cover has been set in place and properly tightened.
10.14 Activation procedure for TTG (L5) and LCD (L1)
— Press the (2) and (3) keys together for 3 seconds until a
special symbol appears in the low left corner of the display
— Press the (4) key
— The HMI enter in the configuration menus:
