LED Configuration
The LEDs can be configured within menu:
[Device Para/LEDs/Group X]
Attention must be paid to insure that there are no overlapping functions due to
double or multiple LED assignment of colors and flashing codes.
If LEDs are configured as
»Latched=active«,
they will k
eep (return to) their
blink code and color even if there is a power outage within the power supply of
the protective device.
If the LEDs are configured as
»Latched=active«,
t
hey will also retain their blink
code and color even if the LEDs are reprogrammed in another way. This also
applies if the LEDs are set to
»Latched = inactive«. 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
side of the display (Group A).
If your device is also equipped with LEDs on the right hand side of the display
(Group B), the analog information in this chapter is valid. The only difference
between “Group A” and “Group B” is within the menu paths.
Via the
»INFO«
push-button, it is always possible to display the current
pickup
s and alarm texts that are assigned to an
LED. Please refer to the
Navigation section for a description of the »INFO« push-button functionality.
Set the following parameters for each LED.
•
»Latching (self holding function)«: If »Latching« is set to »Active«, the state that is
set
by the
pickup
s will be stored
until it is reset. If »Latching«
is set to
»Inactive«, the LED always adopts the state of those
pickup
s that were assigned.
•
»Acknowledgement«: Signal that will reset the LED.
•
»LED active color«: LED lights up in this color when 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 when none of the allocated functions is valid (red, red-flashing, green,
green flashing, off).
•
»Assignment 1...n« Apart from the LED for System OK (Operational), each LED can be assigned up to five functions
(e.g.
pickup
s) out of the »Assignment list«.
•
»Inverting an Assignment 1...n«: This will invert the input signal.
