When no error are active, it appears the string “All Alarms clear”.
When an error condition is active, corresponding error code is
displayed plus a short textual description and a brief suggested
action about how it could be fixed.
The error code is the combination of the letter relating its
NAMUR NE107 classification (F, M, S, C), its internal priority
number and a three digit code.
Its Namur classification correspond at how the error has
been mapped in the RB_FD_xx_MAP (Where xx = FAIL; MAINT;
OFFSPEC; CHECK)
If more errors are active together, they are displayed into this
page according to their priority. They can be visualized by
scrolling up/down the screen with the two central buttons and
their order is indicated by the bar and number on the right side
of the display.
Configuration of the field indicator using
the housing push buttons
The Z and S buttons are located under the housing metallic
type plate together with the Write Lock & rotation switch.
The Write Lock button
Write locking prevents the configuration data from being
overwritten by unauthorized users. If write lock is enabled, the
Z and S buttons are disabled.
When the JDF300 is write locked, the lock symbol is displayed
in the bottom side of the display.
However, when write lock is enabled it is still possible to read
out the configuration data through the HMI local menus or
using DD based configuration tools.
Write lock is activated as follows (also refer to the symbols on
the plate):
1
First, use a suitable screwdriver to press the switch down
fully.
2
Then turn the switch clockwise by 90°.
To deactivate the switch, push it down slightly and then
turn counter clockwise by 90°.
The Z and S functions
When the JDF300 is used as indicator of more than one
variable, the
Z
button is used to locally select the one to be
displayed.
By default the
“MAO_CHANNEL”
selects the input 1 but it can be
changed selecting any of the 8 inputs of the MAO block.
When it is held down for more than 0.5 seconds, when released
the
“MAO_CHANNEL”
is switched to the next valid input.
The next valid input is the next enabled into
“HMITB_INPUT_ENABLED” (index 33)
. Only the inputs enabled
into this parameter can be selected and displayed.
