A: Door opening angle "β"
B: Door width "C" in mm
C: Door gap "D" in millimeters for overlapping "B" = 0 mm
Calculation example
The actual door gap "D1" is calculated using door gap "D" calculated by
means of the table above minus the overlapping "B" of door and frame:
D1 = D – B
Example:
A safety guard with a 40 mm aluminium profile of 950 mm long must be
protected by means of a TVS 410. According to the technical datasheet,
the safety contact of the TVS 410 opens at 3° in new state (10° at the
end of lifetime). According to the table above, this results in a door gap
of approx. 49.7 mm in new state.
The actual door gap, calculated according to the formula above
D1 = D – B, is (49.7 – 40 = 9.7); D1 = 9.7 mm .
At the end of the lifetime, the door gap is approx. 164.9 mm and the
actual door gap (164.9 – 40 = 124.9); D1 = 124.9 mm.

5. Set-up and maintenance
Functional testing
The safety function of the safety components must be tested.
The following conditions must be previously checked and met:
1. Correct fixing of the component
2. Check the integrity of the cable entry and connections
3. Check the switch enclosure for damage
5.1 Maintenance
We recommend a regular visual inspection and functional test,
including the following steps:
1. Check fitting of the hinge safety switch
2. Remove particles of dust and soiling
3. Check cable entry and connections
4. Examination of the switching angle
Damaged or defective components must be replaced.
6. Disassembly and disposal
6.1 Disassembly
The safety switchgear must be disassembled in a de-energised
condition only.
6.2 Disposal
The safety switchgear must be disposed of in an appropriate manner
in accordance with the national prescriptions and legislations.
