Application
Hazardous areas often require the use of optical signals for
warning, infor mation or signalling purposes. The Ex-LED
Light Expertline-LED provides these signalling options. The
available operating modes are Continuous light, Strobe light,
Blinking light and Rotating light, and turning on the supply
voltage activates the device. The Ex- Light is equipped with
high performance light-emitting diodes (LEDs) and comes
in the colours white, red, yellow, green and blue. The housing
conforms to protection degree IP66 and is suitable for both
indoor and outdoor use. When looping through several devi-
ces successively, please observe the maximum current con-
sumption of 8 A.
Design
The plastic housing and the dome consist of impact-resi-
stant polycarbonate. The dome with the LEDs is completely
filled with transparent compound. The complete electronics
are also encapsulated in the compound. Thus, the "encap-
sulation" type of protection is established. The terminal room
has been designed according to the "increased safety" type
of pro tection.
The slide switch for adjusting the operating modes has the
'intrinsically safe' type of protection. A metal bracket serves
as wall mounting.
Mounting
The device may be placed in any position. The mounting
angle can be rotated 90°, requiring you to loosen the
4 hexagon socket screws using a 4 mm Allen key, rotating
the mounting angle in the desired position, inserting the
screws and tightening them. The device is fastened with 2
screws (ø 6 mm or 8 mm) on the wall/ceiling.
Setting the operating modes
The operating modes are set using the four slide switches in
the terminal room.
The following operating modes may be set:
• Strobe light
Switch 1 only to ON
• Blinking light
Switch 2 only to ON
• Rotating light
Switch 3 only to ON
• Continuous light
Switch 4 only to ON
If more than one switch is set to ON, then operating mode
„Strobe light" is activated.
Connecting
Open the terminal room on the underside of the Ex-LED
Light. Lay the connecting cable through the cable gland,
secure the connecting cable using the cable gland nut and

The Ex-LED Light Expertline LED comes in a direct current
24 V
version and in an alternating current 230 V
DC
In the case of the direct current version, please observe the
polarity of the connections. For the alternating current version,
the cable ends can be randomly connected. Then close the
terminal room with the terminal room lid. The screw torque is
0.9 ... 1.1 Nm.
Notes on cable gland and cable entry
The cable glands must meet the requirements of protection
against
explosive
atmospheres,
-40°C
Ta
+70°C and IP degree of protection IP66. Use
only suited tools for connecting the cable and installing the
cable gland! The cable gland is suited for permanent wiring
only. In case of factory fitted cable glands the attached
operating instructions have to be considered.
Service
No maintenance required.
Commissioning
After having been connected to the mains, the signalling light
is operational. Start operating with closed housing only.

Care and maintenance
The signalling light contains no serviceable parts. The requi-
rements of EN 60079-17 regarding the regular control of the
explosion protection must be applied.
