Please note the following conditions:
• The configuration guidelines for AS-Interface apply. For all
M12 connecting cables the maximum permissible current is
limited to 4 A. The cross-section of these cables amounts to
just 0.34 mm². For connection of the K60R modules, the afore-
mentioned M12 connecting cables can be used for the spur
lines. The voltage drop caused by the ohmic resistance
(approx. 0.11 Ω/m) must be taken into account.
• For round cable connections with shared AS-i and U
AUX
in a
single cable, the following maximum lengths apply:
- Per spur line from feeder to module: maximum 5 m
- Total of all round cable segments in an AS-Interface network:
maximum 20 m
Tests IP68/IP69K
K60R modules were tested with the following tests:
• Stricter test than IP67:
90 min in 1.8 m depth of water (IP67: 30 min at 1 m depth of
water)
• Salt water test:
Five months in salt water, 20 cm deep, at room temperature
• Test with particularly creepable oil:
Five months completely under oil at room temperature
• Test with drilling emulsion:
Five months at room temperature (components of the drilling
emulsion: Anionic and non-ionic emulsifiers, paraffinic low-ar-
omatic mineral oil, boric acid alkanolamines, corrosion inhibi-
tors, oil content 40 %)
• Test in oil bath (Excelence 416 oil) with alternating oil bath
temperature:
130 cycles of 15 °C to 55 °C, two months
• Cleaning with a high-pressure cleaner according to IP69K:
80 bar to 100 bar, 10 cm to 15 cm distance, time per side
> 30 sec, water temperature 80 °C
To simulate requirements as realistically as possible the modules
were artificially aged prior to the tests by 15 temperature cycles
of -25/+85 °C. During the test the modules were connected to
3RX1 connecting cables. Unassigned connections were closed
with 3RK1 901-1KA00 sealing caps.
Note:
Sealing caps and M12 connections must be tightened with the
correct torque
