2 Safety

2.1 Safety instructions

– Only use the product in original status without unauthorised modifications.

– Only use the product if it is in perfect technical condition.

– Take into consideration the ambient conditions at the location of use.

– Prior to mounting, installation and maintenance work: Switch off power sup-

ply and secure it from being switched back on.

2.2 Intended Use

The purpose of the valve unit is to control a pneumatic cylinder in balancer applic-

ations.

The product is intended for use in industrial environments. Outside industrial

environments, e.g.in commercial and residential/mixed-use areas, it may be

necessary to take measures to suppress radio interference.

2.3 Training of skilled personnel

Installation, commissioning, maintenance and disassembly should only be con-

ducted by qualified personnel.

The specialized personnel must be familiar with the installation and operation of

electrical and pneumatic control systems.

5 Product overview

5.1 Functional Principle

The valve unit consists of a 3/3-way proportional-pressure regulator and

two2/2-way valves. The purpose of the 3/3-way proportional-pressure regulator

is to regulate the cylinder pressure and the cylinder position. The two2/2-way

valves serve as non-return valves for shutting off the cylinder volume in the event

of an error (loss of voltage, fall in pressure, too high travel speed, etc.). For

increased safety requirements, the valve unit can be equipped with switching pos-

ition sensing for the non-return valves (VPCB-...-T22-M).

6 Mechanical installation

1. Make sure there is sufficient space for the connecting cable and tubing con-

nections.

This will prevent kinks from forming in the connecting cables and the

tubing.

2. Place the valve as close to the consumer as possible.

This leads to better control response.

3. Attach the valve using the 4 screw holes M5 (10mm deep) under the valve or

on the valve side with the pneumatic connections (1) and (3). Tightening

torque: 5Nm£

7 Installation

7.1 Pneumatic Installation

1. Attach the following connections:

– Connection (1) compressed air

– Connection (2) working air (balancer cylinder)

2. Fit a silencer at the exhaust air connection (3) or provide for ducted exhaust

air .

NOTICE!

Pay attention to compressed air quality.

Damage to property or loss of function from lubricated compressed air.

• Operate product only with unlubricated compressed air.

• Observe the requirements for compressed air quality Technical data.è

7.2 Electrical installation

WARNING!

Risk of injury due to electric shock.

• For the electric power supply, use only PELV circuits that ensure a reliable

electric disconnection from the mains network.

• Observe IEC60204-1/EN60204-1.

1. Earth the shielding of the connecting cable on the cable end that is furthest

from the valve.

2. Install electrical connecting cables without squeezing, kinking or stretching.

3. Fasten the earthing cable with self-tapping screw and toothed disc to the

earth terminal of the valve.

4. Screw the electrical connecting cable for CAN-BUS to the 5-pin M12 plug con-

nector (connection X1). Tightening torque: 0.4Nm.£

The maximum permitted length of the electrical connecting cable for the CAN-

BUS is 30m.

5. Remove the cover cap and screw the electrical connecting cable for the dis-

placement encoder onto the 8-pin M12 socket (connection X2). Tightening

torque 0.4Nm.£

The maximum permitted length of the electrical connecting cable for direct

connection with the displacement encoder system of the DNCI is 1.5m.

The maximum permitted length of the electrical connecting cable to the

sensor interface is 2m.

6. Connect the electrical connecting cable for non-return valve 1 and 2.

7. Connect the switching position sensing for non-return valve 1 and 2 (option-

al).

10.2 Diagnostics via controller

The fault messages of the valve are sent to the higher-order controller (e.g. CECC-

D-BA).

10.3 Error status

The following valve errors lead to a switch-off in the power stage:

– Coil temperature too high

– Valve is jammed

– Hardware interface to the actuator is faulty

–

Supply voltage is too low when switching on the valve ( 18VDC)<

When switching off the power stage, the valve has an undefined opening cross

section.

With all other errors, the valve is in the mid-position and pressure is constrained.

Communication and sensors remain active.

The pressure in the cylinder can be constrained by shutting off the two non-return

valves.

11 Conversion to direct pressure measurement on the cylinder

The mounting of the connection set for direct measurement of working pressure

on the cylinder is described in the instruction manual VABS-P15-S-B6.

12 Disassembly

1. Switch off operating voltage.

2. Switch off compressed air supply.

3. With a pin or screwdriver, press the manual ventilation and ventilate the sys-

tem Fig.1.è

The air volume trapped in the cylinder and in the connecting cables is

exhausted.

4. Remove electrical connecting cables.

5. Remove compressed air lines.

6. Dismantle the product.
