Alarm Signal output [AL]
The Inverter alarm signal is active when a fault has occurred and it is in the Trip Mode.
When the fault is cleared the alarm signal becomes inactive.
We must make a distinction between the alarm signal [AL] and the alarm relay contacts AL0, AL1and AL2.
The signal [AL] is a logic function which you can assign to the relay output terminal RN.
The most common (and default) use of the relay is for [AL], thus the labeling of its terminals.
Option Terminal
Code Symbol
5 AL
Valid for inputs:
Required setting
Notes:
• When the alarm output is set to normally closed
[NC], a time delay occurs until the contact is closed
when the power is turned on.
Therefore, when the alarm contact output is to be
used, set a delay of about 2 seconds when the
power is turned on.
Terminals RN0 and RN1 are relay outputs,
so the electric specification of [AL] is similar to
the contact output terminals AL0, AL1, AL2.
• See the description of AL1, AL2 and AL0.
• When the inverter power supply is turned off,
the alarm signal output is valid as long as
the external control circuit has power.
• The signal output has the delay time
(300ms nominal) from the fault alarm output.
• Output terminal RN is a relay contact a.
In case of contact b, setup C14.
