4.4.11 External 3-PM-IO module and ext.
3-PM-IO-INV module inverse
Description/Scope of application
The electronic monitoring module is used for light switch
monitoring, in this way the general lighting and luminaires
for the safety lighting can be switched together during
mains operation. The module is also used for 3-phase
monitoring in conjunction with EATON safety lighting
systems of type ZB-S.
Principle of operation
The CEAG 3-PM-IO and 3-PM-IO-INV module has 8
separate input channels for monitoring 230 V AC mains
voltages. Associated yellow LEDs on the front panel
indicate the switch state. Using the left rotary coding
switch on the front panel, the module can be switched
from DLS (maintained light switch monitoring) to 3PH
(three phase monitoring). In the “DLS only” position all 8
input channels are active for DLS (maintained light switch
monitoring). In the “DLS 3PH” position, channels 1 - 5 are
active for DLS (maintained light switch monitoring) and
only the input channels 6 (L1); 7 (L2); 8 (L3) are active
for 3 phase monitoring. The RS 485 interface as well as
the 24 V DC power supply are supplied from the EATON-
safety lighting system. The 230 V switching command
at the inputs 1-8 is forwarded to the CEAG emergency
lighting system over the BUS. The safety luminaires
connected to the emergency lighting system are switched
on and off as per the programming.
The test button triggers a mains/emergency light fault
on the respective ZB-S system after actuation and the
connected emergency lighting switches on.
At the same time, the red error/fault LED lights up.
The green LED on the front panel indicated malfunction-
free operation; the red LED indicates a malfunction. If
several modules (max. 25) are operated in an emergency
lighting system, the RS 485 bus and the 24 V supply are
to be connected in series. The screen on the bus cable
is to be connected to the SE terminal using a suitable
clamping arrangement.
A terminating resistor (120 Ω) must be fitted at the start
and end of the BUS cable. For this
purpose, a jumper is to be fitted to terminals
B1/B2 on the last module; this activates the built-in
terminating resistor.
If the safety system is at the start of the bus cable, then
the appropriate terminating resistor is to be fitted to
terminals provided for this purpose.
