34 3-PM-IO-INV Module
In order to avoid the risk of power failures, it is necessary
to permanently monitor the function of the general lighting
light distributors in order to switch on the safety lighting in
the event of a fault. The 3-PM-IO-INV modules are therefore
an important part of the safety system. The safe functioning
of the entire system must be constantly monitored and, in
the event of faults, the system must switch on the safety
lighting automatically. The results of both automatic and
manual tests must be logged. At the same time, emer-
gency luminaires should be switched on with the general
lighting during normal operation. EATON´s 3-PM-IO-INV
modules offer all these functions in one device in compli-
ance with standards. Deviating from the 3-PM-IO module,
the 3-PM-IO-INV module offers inverted measuring inputs
so that individual circuit breakers can be monitored with
integrated signalling contacts.
The easily accessible test button offers the advantage that
an interruption of the mains voltage is not necessary to
check the function of the voltage monitoring devices. As a
rule, one of the monitored phases must be enabled without

a test button, which at least leads to a failure of the power
supply of the general lighting and thus to severe disturban-
ces of the operational processes.
IMPORTANT NOTE
Inputs 6 to 8 report a power failure which is forwarded to
the visualization (HMI, WEB, VisionGuard) with the desti-
nation specified in the test book. Inputs 1 to 5 are used to
query the light switch for general lighting and do not signal
a power failure.
