Safety instructions
Please absolutely observe!
Please read and observe the following operation instructions before installation and start-up
and all further works with the control panel SN 2960 / SN 2962 / SN 2963 / SN 2965.
Special designs of the STRACK control panels must be used according to these operating
instructions. Upon release of a new version, these operating instructions lose their validity.
ATTENTION!
If the control panel is improperly used or dismounted, the following things threaten:
- Risks to health,

1. Features
Differently charged gas springs can cause a canting of the tool.
By connecting of the gas springs with high-pressure hoses, it is guaranteed that all gas springs
have the same pressure.
Due to a control panel (SN 2960 / SN 2962 / SN 2963 / SN 2965) fitted on the tool, all gas
springs are simultaneously filled or released.
By using the manometer in the control panel, the filling pressure can be controlled at each time.
2. Types
The program of STRACK NORMA includes different types for such applications.

3. Installation
The control panels SN 2960 / SN 2962 / SN 2963 and SN 2965 can be connected with a plate
by means of screw-fixing.
During the installation of the control panel in the upper part of the tool, the screws must be
secured with screw-locking adhesive (medium-strength) due to arising vibration exposure.
3.1 Installation with special design
3.1.1 SN 2960
During the installation of a special design, the panel is also fixed by means of screw bore holes,
the filling of the plate is effected by means of the boring in the rear side (example at SN 2960).
3.1.2 SN 2962
Here the filling of the plate is effected by means of an additional connecting piece.

3.1.3 SN 2963
The filling of the tankplate over the control panel SN 2963 can be effected as well as it is the
case at the control panel SN 2960 by means of a boring with o-ring sealing directly on the plate.

4. Initial set-up
4.1 Filling of the system pressure
At the initial start-up after the installation of the STRACK nitrogen gas spring systems, the
system must be filled.
Proceed as follows:
ATTENTION! During all works at the STRACK nitrogen gas spring system, the applicable
operating safety regulation paragraph 3 must be considered.
The initial start-up and operation of the STRACK gas spring system must
exclusively be done by personnel which has been trained and instructed by
STRACK.
1. Drive the press in the top dead centre and stop it there.
2. Close the release valve of the
used control panel.
3. Connect the charging hose SN 2967 LS on the one side with the quick coupling
of the control panel and on the other side with the pressure reducer of the nitro
gen bottle.
Adjust the pressure reducer to maximal gas spring filling pressure, e.g. 150 bar.

4. Open the shut-off valve of the nitrogen bottle.
5. Open slowly the valve (1) at the charging hose.
Now fill the whole system with nitrogen. After the piston rods are completely
extended, you can continue to open the valve (1) at the charging hose to
accelerate the charging process.
Adjust the pressure how you need it later.
This pressure must lie between 50 and 200 bar.
Observe that the system pressure can slightly decrease after the initial filling due
to system constraints.
6. Close the valve (1) at the charging hose (2) as well as the valve at the nitrogen
bottle.
7. Decouple the charging hose from the control panel.
Now the system pressure is the same in all gas springs.
NOTE
Decouple the nitrogen bottle during the operation
of the gas spring system.
4.2 Modification of the system pressure of the gas springs
The control panels allow a simultaneously control of several gas springs.

4.3 Release of the pressure at a gas spring bloc
Now open slowly the release valve and observe the manometer of the gas spring, which should
be reduced in pressure.
Close the release valve at the desired pressure.
ATTENTION!
Please consider the respective indicated minimal- and maximal
filling pressure for the gas springs contained in the catalogue.
Now the gas spring has the selected initial force.
4.4 Increase of the pressure at a gas spring
a) Connect the charging hose (a) of the charging equipment
SN 2967-LS including the pressure reducer and the
nitrogen bottle closely to the filling valve (quick coupling) (1)
of the control panel SN 2960.
b) Open the release valve of the nitrogen bottle.
c) Open slowly the valve at the charging hose.
Now fill the selected gas springs with nitrogen.
(Force see table in annex)
d) Close the valve at the charging hose
as well as the valve at the nitrogen bottle.
e) Decouple the charging hose (2) from
the control panel.
NOTE If the control panel SN 2960 is equipped with a pressure controller,
disturbances can occur, if the adjusted pressure at the control panel is under
the adjusted minimum pressure of the pressure controller.
Thus, the press can be blocked.
In such a case, you have either to increase the pressure again or to adjust the
pressure controller to this new value.
