If the »INFO« key is pressed a second time, the »main overview of the right LEDs« are
displayed (if available).
By pressing the softkey »left« (or the »INFO« key a third time) you will leave the main LED
menu.
The main overview shows the 󰊎rst assignments of the LEDs. Periodically the available
softkeys will be shown.
LED multiple assignment page:
On the main overview page use the softkeys »up« and »down« to select an LED.«
From there you can enter the »LED multiple assignment page« by pressing
softkey »right«.
This page gives you detailed information of all states assigned to this LED. An arrow
symbol points to the LED whose assignments are currently displayed.
Via the softkeys »up« and »down« you can call up the next / previous LED.
By pressing the softkey »left« you will return to the main LED overview.
Latching
If an LED is con󰊎gured as »Latched« = “Active”, it will keep its state – regardless
whatever may happen – until it is acknowledged (see “Acknowledgment Options” below).
A latched LED gets reset only in any of the following cases and only after all assigned
trigger signals have dropped out:
• It is acknowledged (either by the user at the HMI, or via SCADA), see below.
• It is reset (acknowledged) by the signal that has been assigned to the
parameter »Ack signal«.
In particular, a latched LED does not get reset in the following cases:
• An LED that had been con󰊎gured as »Latched« = “Active” keeps its state, even if it is
re-con󰊎gured to some other setting. This also applies if it is re-con󰊎gured
to »Latched« = “Inactive”.
• Switching o󰊍 the EMR-3MP0 does not reset latched LEDs, because after a (warm or
cold) restart, every latched LED will return to its individual (previously assumed)
state.
Acknowledgment (Reset) Options
Resetting a latched LED will always require an acknowledgment. (For a detailed
description, see ╚═▷ “Resets”.)
LEDs can be acknowledged by:
• The push-button »Ack/Rst« at the operating panel;
• The LED can be acknowledged by the signal that has been assigned to the
parameter »Ack signal«.
