35 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 CEAG 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, emergency luminaires should be switched on
with the general lighting during normal operation. EATON´s
CEAG 3-PM-IO-INV modules offer all these functions in one
device in compliance 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 5 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.
