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
two2/2-way valves. The purpose of the 3/3-way proportional-pressure regulator
is to regulate the cylinder pressure and the cylinder position. The two2/2-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.
Ä
This will prevent kinks from forming in the connecting cables and the
tubing.
2. Place the valve as close to the consumer as possible.
Ä
This leads to better control response.
3. Attach the valve using the 4 screw holes M5 (10mm deep) under the valve or
on the valve side with the pneumatic connections (1) and (3). Tightening
torque: 5Nm£
7 Installation
7.1 Pneumatic Installation
1. Attach the following connections:
– Connection (1) compressed air
– Connection (2) working air (balancer cylinder)
– Connection for control element 1 Applicable Documentsè

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 IEC60204-1/EN60204-1.
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: 0.4Nm.£
The maximum permitted length of the electrical connecting cable for the CAN-
BUS is 30m.
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 0.4Nm.£
The maximum permitted length of the electrical connecting cable for direct
connection with the displacement encoder system of the DNCI is 1.5m.
The maximum permitted length of the electrical connecting cable to the
sensor interface is 2m.
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).

Tab. 6 LED
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 ( 18VDC)<
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
Ä
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.
