Adjusting the valves

In the condition as delivered, the ELDRO

®

thrusters are set to 5

seconds of setting time and resetting time. 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 ELDRO

®

thruster is equipped with valves (see

type plate;

⇒

Type designation and type key section). The H (lifting

valve) and S (lowering valve) marks are embossed into the housing.

Examples for the version with valves:



Lowering valve (S):

e.g. Ed 50/6 S



Lifting valve (H):

e.g. Ed 80/6 H



Lifting and lowering valve (HS): e.g. Ed 121/6 HS

All thrusters (apart from the Ed 630) can be equipped or
modified with valves retrospectively by the manufacturer.

6.3.1

Adjustment screw installation location

The installation location for the adjustment screws is specified on the
dimensional drawings (

⇒

Dimensions section).

Adjustment screw H for the set time (lifting time) is located to the left
of the type plate below a sealing plug. See the “H” on the housing.

Adjustment screw S for the reset time (lowering time) is located to the
right of the type plate and is also below a sealing plug.

See the “S” on the housing.
