3 Functional description

3.1 General

Hägglunds Compact CA 50-210 motors in 2-speed

configuration in combination with VTCA 600 valve can shift

displacement from full to half displacement while running

up to 30 rpm and high pressure maximum 105 bar.

Displacement shift from half to full displacement is not

allowed while the motor is rotating.

Shifting from full to half displacement means that 25% of

the pistons are provided with high pressure and 75% of the

pistons are provided with low pressure. This resulting in

twice the speed and half the output torque compared to

full displacement. The valve can be mounted directly onto

the motor and can be used in both open and closed loop

systems.

When ordering a motor prepared for 2-speed function the

main rotation, clockwise (R) or counter clockwise (L), has

to be specified. With wrong direction, load on the piston

will be increased 3 times, which can give overheating of the

pistons.

With the flow inlet connected to P (A-port on motor), the

motor shaft rotates in the directions shown by arrows. (see

Fig. 1 and Fig. 2) R-motor rotates clockwise, and L-motor

counter-clockwise, viewed from the motor shaft side. If the

motor is working in half displacement, and in reversed

”direction of rotation”, is the allowed pressure max 210 bar

(3000 psi).

For higher speed, two valves can be used, one standard

valve and one S-index 05 valve (mirrored inverted).

Maximum operating pressure is 350 bar (5076 psi) and

maximum flow 600 l/min (158 gpm). When using a 2-speed

motor, check the system temperature due to higher

pressure loss, flushing may be necessary and 2-speed

applications for motors with reduced displacements are not

recommended.

The valve is available in five main configurations:

• VTCA 600 0 H: Hydraulic operated displacement

shift.

• VTCA 600 0 H S-index 05: Hydraulic operated

displacement shift. Two valves.

• VTCA 600 0 E: Electric operated displacement shift,

24 VDC.

• VTCA 600 E S-index 05: Electric operated

displacement shift, 24 VDC. Two valves.

• VTCA 600 B E: Electric operated displacement shift

with brake control function, 24 VDC.

3.2 Function

3.2.1 Valve VTCA 600 0 H 0 and VTCA 600 0 H 1

Hydraulic operated valve.

The displacement shift function is controlled by a

directional valve (2), see Fig. 6, which is kept in the full

displacement position by spring action. The control

pressure for the directional valve is obtained from an

external source through port “Pc“.

3.2.2 Valve VTCA 600 0 E 0 and VTCA 600 0 E 1

Electrical operated valve

The displacement shift function is controlled by a

directional valve (2), see Fig. 7, which is kept in the full

displacement position by spring action. The control

pressure for the directional valve is controlled by an

electrical operated directional valve (3) see Fig. 7. The

control pressure is obtained from an external source

through port “Pc“ or internally from “P“.

Using internal control pressure from “P“

(Only VTCA 600 0 E)

The VTCA 600 valves are at delivery prepared for control

pressure connection at “Pc“. In case of electric operated

valve (VTCA 600 0 E), the control pressure can be obtained

internally from “P“ by following instructions below and Fig. 3.

1. Remove plug (B).

2. Remove plug (010).

3. Mount plug (B), tightening torque: 10 Nm.

4. Install a plug at connection

3.2.3 Exchange of oil in motor casing

VTCA 600 0 H 1, VTCA 600 0 E 1 and VTCA 600 B E 1

are prepared for exchange of oil in motor casing. Nominal

oil exchange, with an orifice with a Ø 2 mm hole, is 12 l/

min (3.1 US gal/min) at a pressure in “C“-line of 25 bar

(365 psi).

3.2.4 Valve VTCA 600 B E 0 and VTCA 600 B E 1

Electric operated with brake function.

(See Fig. 8 and Fig. 9)

The displacement shift function is controlled by a

directional valve (2) which is kept in the full displacement

position by spring action. The control pressure for the

directional valve is controlled by an electrical operated

directional valve (3), ISO 4401, included in delivery. The

control pressure is obtained from an external source

through port “Pc“.

Brake function

The brake function is electrical operated. The control

pressure for the brake is controlled by two electrical

operated directional valves (3 and 6), and the brake is

connected to connection “BR“. The control pressure is

obtained from an external source through port “Pc“.

Brake o

When the electrical operated directional valves are open,

the pressure from “Pc“ shifts the directional valve (4),

check valve (5) is closed and the pressure are guided to

“BR“ and the brake release.

Brake on

When the electrical operated directional valve (3) is closed,

the directional valve (4) shifts and the check valve (5)

opens. Spring pressure in the brake cylinder pushes then

oil to tank and the brake applies.

The VTCA 600 0 H 0 and VTCA 600 0 E 0 valves are, at

delivery not prepared for exchange of oil in motor case.

Port (8 )is plugged, and port (9 )is not plugged.

See also hydraulic circuits Fig. 6. and Fig. 7

The valve can be prepared for exchange of oil in motor case

by following instructions and Fig. 5.

NOTICE

High internal pressure in motor case

Risk of damage motor.

▶ Make sure that an external draining line is connected to

one of the external drain connections D1, D2 or D3 on

the motor.

1. Replace the plug (008), M8, with an orifice, material ID

R939055162

2. Install plug (009), R3/8˝, material ID R913053036.

3. Lock the plugs with Loctite 577 or similar.

WARNING

Escaping oil mist!

Risk of explosion, re health hazard, environmental

pollution.

▶ Depressurize the system including valve and repair the

leak.

▶ Keep open ames an ignition sources from the

Hägglunds valve

Static discharge

Cleaning the valve with a dry rug may lead to explosions

through electrostatic dis-charge that may cause severe

injuries and even death

▶ Do not use a dry rug for cleaning

Lack of grounding

Risk of explosion that may cause severe injuries and even

death

▶ The valve must always be tted to the motor or via

adapter tted to the motor. The valve must be electrical

conductive and equipotential bonded with the motor

which must be grounded to the system.

▶ The valve are not allowed to be tted to any separate

bracket without grounding of the valve.

Painting

Risk of explosion that may cause severe injuries and even

death

▶ The valve must not be painted or otherwise coated

with non-conductive sub-stances!

▶ Any change at the surface protection will lead to loss of

explosion protection!

DANGER
