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 èTechnical data.
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. Ground 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. Mount the earthing cable with self-tapping screw and toothed disc to the
earth connection of the valve.
4. Screw the electrical connecting cable for CAN-BUS to the 5-pin M12 plug con-
nector. Tightening torque: £ 0.4Nm.
The maximum permitted length of the electrical connecting cable for the CAN-
BUS is 30m.
5. Remove cover cap and screw electrical connecting cable for the displacement
encoder system onto the 8-pin M12 socket. 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).

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 è Fig.1.
ÄThe 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.
