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 CEAG safety
lighting systems of type ZB-S.
Installation
For the mounting and
operation of electrical appa-
ratus, the respective national
safety regulations as well as the
general rules of engineering will
have to be observed.
Assembly
The installation location is to
be chosen in accordance with
the applicable construction
standards (e.g. subdistribution
boards). During this process
attention is to be paid to tem-
peratures outside the permitted
range at the installation location
during operation.
Principle of operation
The DLS /3PH bus 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 slid-
er switch on the front panel, the
module can be switched from
DLS (maintained light switch
monitoring) to 3PH (three phase
monitoring). In the DLS position
all 8 input
channels are active for DLS
(maintained light switch moni-
toring). In the 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 moni-
toring. The RS 485 interface
as well as the 24 V DC power
supply are supplied from the
CEAG-safety lighting system.
The 230 V switching command
at the inputs 1-8 is forwarded
to the CEAG emergency light-
ing system over the BUS. The
safety luminaires connected to
the emergency lighting system
are switched on and off as per
the programming.
The green LED on the front
panel indicated malfunction-free
operation; the red LED indicates
a malfunction. If several mod-
ules (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 appro-
priate terminating resistor is to
be fitted to terminals provided
for this purpose.
