2. Description
The explosion-safe signal lights AR-077 have been designed to attract attention in a safe manner in
environments where explosion hazards may exist. For example to indicate a telephone call, indicating the
status of a machine or report a malfunction or hazard that requires immediate action.
The signal light comprises a metal housing with a transparent dome covering the light source. This can be a
flashing or continuous light source. The interior of the transparent dome has light dispersing ribs to
contribute attention of the light beam.
The explosion safety to gas is arranged by the application of protection degree against ignition ‘Flameproof
enclosure’ in addition to the model with connection terminals protection degree ‘increased safety’has been
applied. The explosion safety to dust is arranged by the application of protection degree against ignition
‘protection by enclosure’.
The dome is made out of high quality polycarbonate with an exceptionally high impact resistance of more
than 7 Nm. Therefore the dome is not equipped with an extra guard.
The signal lights can be supplied in various models, differing with respect to:
a. the light source;
b. the light color;
c. the voltage;
d. the material of the armature;
e. the type of electrical connection.
Each of these options are explained in more detail further in this document.
The specific model is identified by the model code. See the table below.

a. Light source
The signal light can be supplied in two different basic types: Strobe Flashing or Steady Burn each with
their own specific type of light source as described below.
Xenon lamp (flashing light)
The strobe flashing light contains an electronic printed circuit board with a xenon gas filled lamp.
When operating it produces bright flashes of light with the energy of 5 Joules at a frequency of
approximately 60 flashes per minute. The printed circuit board has a small potentiometer with which
the flash frequency can be changed within the range of approximately 50 to 80 flashes per minute.
Multi-LED reflex lamp (steady burn or blinking status light)
The steady burn or blinking status light contains electronics with a multi-LED reflex lamp.
b. Light color
The color of the Xenon flashing light is obtained by inserting a color-fast lens. In case of the Multi-LED
reflex lamp, the color is created by using colored LED's. In both cases a stable color is obtained.
c. Supply voltage
With regard to the voltage from the power supply the signal can be supplied for the following voltages.
All the other electrical data is also given in the table.

10. Opening the housing
Compartment with lamp and electronics
The part of the housing that contains the lamp and the electronics is designed as flameproof Ex d and
contains no components that need direct access. It is therefore not accessible to the user. The housing is

User manual explosion-safe AR-077 signal light
Issue April 2020 13 / 16
locked against unintentional opening and may only be opened under non-hazardous safe conditions. To do
this follow the instructions as described under the heading ‘Repair’.
Connection compartment with terminals (Ex de version)
The compartment that contains the connection terminals is accessible to the user by unscrewing the three
cover screws. Opening is only permitted when the power supply has been switched off and the area is
known to be non-hazardous.
11. Maintenance
For maintenance of the AR-077 signal lights the requirements as stated in EN 60079-17 apply. If the signal
light and the connection cable are no longer in good condition or are very dirty or damaged they must be
immediately repaired or cleaned.
The power supply to the signal lights must be switched off and may only be restored after the maintenance
has been carried out and approved.
The advised maintenance cycle for these signal lights depends on their specific use and must therefore be
agreed with the user for the expected use.
12. Repair
Repair of the AR-077 signal lights may only be executed by applying original parts and may only be carried
out by qualified workers who have been trained in accordance with EN 60079-19. Applying of non-original
parts may lead to injury to persons and damage to the equipment.
If non-original parts are used or if repairs are carried out in an incompetent manner, the explosion-safety of
the signal light can no longer be guaranteed. Therefore it is preferred that the signal light is returned to the
manufacturer for repair.
If the housing is opened care must be taken of the following (also refer to the next drawing):
The housing may not be opened unless the area is known to be non-hazardous.
The armature must be disassembled in a logical sequence.
The Ex d cover (foot) of the flameproof Ex d compartment is secured by a special locking screw
mounted in the flange of the cover. The Ex d cover is directly mounted to the Ex d housing. The locking
is arranged by using a cup point screw with internal 2 mm hexagon provision. Its function is twofold;
primary preventing unwanted opening of the housing and secondary establishing a bonding mass
connection between housing body and foot.
The locking screw is inserted through the foot (Ex d cover) which is screwed directly into the housing.
The locking screw is a notching screw with a hexagon socket with 2 mm between the flats.

User manual explosion-safe AR-077 signal light
