The SLT-60 is a surface supplied diving system designed to Compliance simultaneously support two divers conducting heavy work The Surface-supplied diving system SLT 60 has been manu- to a depth up to 60 msw, carrying out all manner of un- factured in accordance with the German standard DIN 58642 derwater work including conducting surveys, maintenance, for hose supplied diving apparatus as well as the 1993/2000 defect rectification, cutting and welding etc. The system EN 250 HSE & NPD regulations for Diving equipment. It also may be used for all underwater maintenance work and complies fully with the new European standard for Surface may be used for diving in both polluted and cold waters.

Decompression underwater Divers would normally use breathing air for most diving operations. Switching over from air to oxygen for decompression purposes during ascent is manually possible by means of the air/oxygen selection valves. A safety blocking system prevents the operator from switching to oxygen be- fore the diver has ascended to a safe depth of seven me- tres.

Should the diver attempt to descend while breathing oxygen, the supply of oxygen is automatically switched over to air once the diver reaches the 9m mark. This is a safety fea- ture working against accidentally supplying the diver with oxygen should he descend to an unsafe depth. V-A Major components 10. Bailout Set. 1.

Oxygen is supplied to the panel at a pressure of 11.5 bar. The front plates can be removed for inspection and maintenance by loosening the securing bolts located around the edges of the plates. The lid of the control panel is secured with wires on either side to keep it open during operation.

The SLT 60 DCP is designed for two divers. Two flexible high- pressure hoses fitted with DIN 200 bar connections are -con nected to the high-pressure inlets.

Each diver has his own independent supply line incor- porating a high performance twostage pressure re- ducing system. The 2 main supply lines are intercon- nected at a point by means of a crossover line fitted with a 90° quarter turn ball valve. The crossover valve is situated at the intermediate pressure level (24 bar).

5. Depth monitoring system The depth of each diver can be read on the two precision depth gauges. (See next figure). The depth gauge is connected to the depth measuring hose in the diver’s umbilical, which ends in the divers chest area.
