switched on
Normal operating state
Error LED lit
An internal relay fault has
been detected
The relay attempts to
reboot. If the error LED
remains lit, call for
maintenance
Alarm LED lit
One or several signals of the
output relay matrix have
been assigned to output
Alarm and the output has
been activated by one of the
signals. (see Chapter 5.5)
The LED is switched off,
when the signal that
caused output Alarm to
activate, e.g. the START
signal, resets. The
resetting depends on the
type of configuration;
Connected or Latched.
TRIP LED lit
One or several signals of the
output relay matrix have
been assigned to output
Trip and the output has
been activated by one of the
signals. (see Chapter 5.5)
The LED is switched off,
when the signal that
caused output Trip to
activate, e.g. the TRIP
signal, resets. The
resetting depends on the
type of configuration;
Connected or Latched.
Resetting latched indicators and output relays
All indicators and output relays can be given a latching
function in the configuration.
There are two ways to reset latched indicators and relays:
1.
Move to the initial display, from the alarm list, by pushing
the CANCEL key for approx. 3 s. Then reset the latched
indicators and output relays by pushing the ENTER key.
2.
Acknowledge each event in the alarm list one by one, by
pushing ENTER the equivalent times. Then, in the initial
display, reset the latched indicators and output relays by
pushing the ENTER key.
The latchings can also be reset via the communications bus or
via a DI input configured for that purpose.
