Light Emitting Diodes (LEDs)
LED
Attention must be paid that there are no overlapping functions due to
double or multiple LED assignment of colors and flashing codes.
If LEDs are parameterized
»
Latched=
active«,
they
will keep (return into)
their blink code/color even if there is a break within the power supply.
If LEDs are parameterized
»
Latched=
active«,
The LED blink code will also
retain, if the LED is reprogrammed in another way. This applies also if
»
Latched is set to ina
ctive«
. Resetting a LED that has latched a signal will
always require an acknowledgement.
This chapter contains information on the LEDs that are placed on the left
hand of the display (group A).
If your device is also equipped with LEDs on the right hand of the display
(group B), the information in this chapter is valid analog. The only
difference is “group A” and “group B” within the menu paths.
Via push button
»INFO«
it is always possible to display the current alarms/alarm texts that are assigned to an
LED. Please refer to chapter
Navigation
(description of the »INFO-key«).
Set the following parameters for each LED:
•
»Latching/self holding function«
: If
»Latching«
is set to
»active«
, the state that is set by the alarms will be
stored. If latching
»Latching« is set to »inactive«
, the LED always adopts the state of those alarms that
were assigned.
•
»Acknowledgment«
(signal from the »assignment list«)
•
»LED active color«
, LED lights up in this color in case that at least one of the allocated functions is valid
(red, red flashing, green, green flashing, off).
•
»LED inactive color«
, LED lights up in this color in case that none of the allocated functions is valid (red,
red flashing, green, green flashing, off).
•
Apart from the
LED for System OK
, each LED can be assigned up to five functions/alarms out of the
»assignment list«.
•
»Inverting«
(of the signals), if necessary.
Acknowledgment options
LEDs can be acknowledged by:
•
Via the push-button »C« at the operating panel.
•
Each LED can be acknowledged by a signal of the »assignment list« (If »
Latched = active«
).
•
Via the module »Ex Acknowledge« all LEDs can be acknowledged at once, if the signal for external
acknowledgment that was selected from the »assignment list« becomes true (e.g. the state of a digital
