14 

A pressure manometer, located on hydraulic cabinet is, when pump is 
running, indicating max. hydraulic working pressure. The pressure is 
manually set and automatically controlled by the hydraulic pressure 
regulator valve. 

Air pressure manometer for air cylinder pressure (tension) control and 
adjustment is located on the air pressure regulator inside the cabinet. 

The air dumping valve

 

is set to dump the tension compensating 

cylinder air pressure whenever the taut wire is outside mooring mode. 
The set point is adjusted at the bottom of the valve and should give an 
air pressure corresponding to 150 kp tension.

Heating System 

Heating elements in electrical motors and outdoor cabinet provides 
heating while the main power switch at the local control panel is 
switched “OFF” to prevent condensation.
