3. Mounting
3.1 General mounting instructions
Mounting: snaps onto standard DIN rails to EN 60715.
3.2 Dimensions
Device dimensions (H/W/D): 100 x 22.5 x 121 mm
4. Electrical connection
4.1 General information for electrical connection
The electrical connection may only be carried out by
authorised personnel in a de-energised condition.
Wiring examples: see appendix
As far as the electrical safety is concerned, the protection
against unintentional contact of the connected and therefore
electrically interconnected apparatus and the insulation of the
feed cables must be designed for the highest voltage, which
can occur in the device.
To avoid EMC disturbances, the physical ambient and
operational conditions at the place where the product
is installed, must meet the provisions laid down in the
paragraph "Electromagnetic Compatibility (EMC)" of
IEC 60204-1.
5. Operating principle and settings
5.1 Operating principle after the operating voltage is switched on
AES 1175
1. The functionality of the safety-monitoring module is tested.
2. If the safety guard is closed or the emergency stop button released,
the enabling paths of the safety-monitoring module will close. The
LED is green.
3. The cable and the connected safety switch are only tested when
the safety guard is opened; the emergency stop button is tested by
actuation (no start-up test).
AES 1176
1. The functionality of the safety-monitoring module is tested.
2. The safety guard must be actuated, in order to check the cables and
the connected safety switch or the emergency stop button must be
actuated (start-up test).
3. If the safety guard is closed or the emergency stop button released,
the enabling paths of the safety-monitoring module will close. The
LED is green.
If the safety guard is opened or the emergency-stop button is actuated,
the enabling path of the safety-monitoring module will open. The
machine is stopped and the LED flashes yellow.
Inputs
Connect the safety switch or the emergency stop switch to the inputs
S13-S14 /S21-S22. X1 / X2 separate inputs for the feedback of the
external contactors.
Extension of enable delay time
On safety guards with strong residual vibrations, the end position of a
non-contact position switch is often "overrun". This causes the safety-
monitoring module to generate an error message. To avoid this, the
"enabling delay time" can be extended by removing the device cover
and setting an internal bridge (jumper).
Bridge closed:
enabling delay time = 1.0 second
Bridge closed:
enabling delay time = 0.1 second
(factory setting)
Additional outputs
External relays for increase in capacity or number of contacts are wired
to the additional outputs Y1 and Y2. The function of the external relays
(with positive action contacts) is tested through the inputs X1 and X2.
The redundancy of the safety-monitoring module thereby is maintained.
6. Set-up and maintenance
6.1 Functional testing
The safety function of the safety-monitoring module must be tested.
The following conditions must be previously checked and met:
1. Correct fitting of the safety-monitoring module
2. Fitting and integrity of the power cable
6.2 Maintenance
In the case of correct installation and adequate use, the safety-
monitoring module features maintenance-free functionality.
A regular visual inspection and functional test, including the following
steps, is recommended:
• Check the correct fixing of the safety monitoring module
• Check the cable for damage.
The device has to be integrated into the periodic check-ups
according to the Ordinance on Industrial Safety and Health,
however at least 1x/year.
Damaged or defective components must be replaced.
7. Disassembly and disposal
7.1 Disassembly
The safety monitoring module must be disassembled in the de-
energised condition only.
7.2 Disposal
The safety monitoring module must be disposed of in an appropriate
manner in accordance with the national prescriptions and legislations.
