Functional description Function sequence Function sequence The hydraulic pump driven by the motor conveys the hydraulic medium into the space below the piston. This generates hydraulic pressure that acts outwards via the piston and lifting rod. The piston and lifting rod move backwards after the motor is switched off either due to a force acting from the outside (brake weight, brake spring) or due to the integrated reset spring.

Assembly and installation Electrical connection 6.2.1 Junction box and terminal diagram There is a connection diagram in the terminal box cover. The motor is voltage switchable for delta connection (Δ) or star connection (Y). On delivery, the devices are connected in star connection (Y). The phase sequence for the connection is arbitrary.
Assembly and installation Electrical connection Terminal board 3-pole with position indicator Lk/La Terminal diagram: Figure 11: 3-pin terminal diagram (single voltage) Screwed connection for motor cable M25 x 1.5 PE earthing conductor terminal 6.2.2 Earthing conductor connection NOTICE If the external earthing conductor connection is used, the thruster’s pivoting ability and the surface temperature must be considered.
If using a quick lowering switch (capacitors) and a motor protection switch, the overcurrent trigger must be adjusted after consulting EMG Automation GmbH. A pivoting arrangement requires a flexible cable. A minimum cable cross section of 1.5 mm must be provided for all thruster sizes.
Assembly and installation Adjusting the valves Unless ordered differently, all three-phase motors are wired for a star connection as delivered from the factory. If required, the user can reconnect the bridges (⇒ Junction box and terminal diagram section) to also operate the motors in delta connection. The motor’s phase sequence and therefore its direction of rotation do not matter.
Assembly and installation Adjusting the valves Examples for the version with valves: Lowering valve (S): e.g. EB 50/50 S Lifting valve (H): e.g. EB 800-60 H Throttle valve (D): e.g. EB 125/60 D All thrusters can be equipped or modified with valves retrospectively by the manufacturer.
Assembly and installation Completing assembly 6.3.3 Changing the set time and the reset time Figure 12: Lifting/lowering valve adjustment parts Screw plug Cylinder casing Regulating plug Guide cylinder Turning the regulating plug (3) clockwise increases the lifting or lowering time. Turning the regulating plug (3) anticlockwise reduces the lifting or lowering time.
