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.
6.3
Adjusting the valves
When the ELHY
®
thrusters are delivered, both the actuating
time and the reset time are not set, i.e. the valves are open a
few turns. The setting times depend on the temperature and
must be adjusted when the machine is at operating
temperature.
The versions with lifting and/or lowering valves enable the lifting rod’s
set or reset speed (setting or resetting time) to be adjusted infinitely
within a specific range. The type designation on the type plate
specifies whether an ELHY
®
thruster is equipped with valves (see
type plate;
⇒
Type designation and type key section).
