Technology
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 performances which only differ in view of the switching perfor-
mance (inverting of the DLS circuits)!
Technical Data


Switching performance of DLS-circuits DLS/3Ph/ Switching performance of DLS circuits DLS/3Ph inverse
U < 138 V = OFF U < 138 V = ON
U > 195 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
Notes:

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 Notlichtsysteme 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!
