4 .4 .6 External DLS/3Ph-bus-module and
ext . DLS/3Ph-bus-module inverse
This electronic monitoring module acts as a (light-)switch
scan and/or for monitoring of the phases of a mains
power supply (e. g. in a subdistribution board):
Luminaires of the general lighting and the safety lighting
are switched in mains operation in accordance with the
switch position and the settings for the controller CU-S
+
.
In emergency operation (e. g. after a message about
a breakdown of monitored phases of the mains power
supply) the circuits of the safety lighting will be operated
according to the settings of the controller CU-S
+
.
DLS/3Ph-bus-modules are available in two perfor-
mances which only differ in view of the switching
performance (inverting of the DLS circuits)!
Technical Data
•
Mains supply for the modules
– Device: 24 V DC (19 ... max. 30 V)
– Cable type: 4 x 2 x 0.8 mm IY(ST)Y, Twistet Pair
screened (minimal standard).
– Current consumption: 20 mA (15 ... 25 mA)
with 8 connected circuits
•
Bus connection
– RS 485
– Rated current: U
n
= 24 V DC
– Cable type: 4 x 2 x 0,8 mm IY(ST)Y, Twistet Pair
screened (minimum standard).
– Connecting terminals A, B, SE
•
Input circuits
– up to 8 potential-free disconnected
– Rated voltage U
n
= 230 V
•
Switching performance of DLS-circuits DLS/3Ph
– U < 138 V = OFF
– U > 195 V = ON
•
Switching performance of DLS circuits DLS/3Ph
inverse
– U < 138 V = ON
– U > 195 V = OFF
•
Switching performance of 3Ph circuits (same for
DLS/3Ph module and DLS/3Ph module inverse)
U < 138 V = OFF
U > 195 V = ON
Application
Two operation modes are available:
•
(pure) DLS-mode
•
(mixed) DLS/3Ph-mode
With a dispatcher (pos. 5) the operation mode can be
chosen.
•
Assembly in the subdistribution board
of the monitored circuits due to the low laying effort
for the illumination circuits (compare «Mounting and
connection of external bus modules»)
•
Assembly in the control cabinet AT S
+
C (AT S
+
S)
due to reasons for simplification of the maintenance
(compare «Mounting and connection of external
modules»).
•
Application-environment
Protection class / -category: IP20 / I
Ambient temp.: -10 ... +40°C
NOTE
•
Please observe the regulations for bus-technology and
screening on the following pages.
•
For planning and application of the modules we advice
to observe the technical documentations attached to
the modules and the catalogues ofCEAG Notlichtsys-
teme GmbH!
•
Optically, the inverse and the non-inverse DLS/3Ph-
module only differ in the printed description and the
item number!
•
Due to break or short-circuit of the RS485-bus line all
connected luminaires will be switched on!
