Safety

2.1 General safety information

 Before work on the product, make sure that the following and been switched off

and secured against being switched on again:
– Compressed air supply
– Power supply

 Observe the handling specifications for electrostatically sensitive devices.
 Commission a valve terminal only if it has been completely mounted and connected.
 For the electrical power supply, use only PELV circuits in accordance with

IEC 60204-1/EN 60204-1 (Protective extra-low voltage, PELV):
 Observe the general requirements IEC 60204-1/EN 60204-1 of the PELV

power circuits.

 Use only voltage sources that ensure a reliable electric separation from the

mains network in accordance with IEC 60204-1/EN 60204-1.

2.2 Use for intended purpose

The valve terminal is intended for installation in machines and automation techno­
logy systems and must be used exclusively as follows:
– In perfect technical condition
– In its original state without unauthorised modifications; the conversions or

modifications described in the documentation are permitted

– Within the limits of the product defined through the technical data
– Only in combination with approved components (e.g. valves, drive/displacement

encoder combinations)

– In an industrial environment
Use for intended purpose is described completely in the documentation. Every
other use is considered not intended.

2.3 Training of specialized personnel

The product may be commissioned only by an electrotechnically qualified person,
who is familiar with the following topics:
– installation and operation of control and automation systems
– applicable regulations for operating safety-engineering systems
– applicable regulations for accident prevention and occupational safety
– documentation for the product

Multi-pin plug connection

5.1

Pin allocation of multi-pin plug connection

Dependent on the plug type of the multi-pin plug connection, within the valve ter­
minal a maximum of 32 solenoid coils can be controlled. Each solenoid coil occu­
pies a pin of the multi-pin plug connection. Numbering of the pins on the valve
terminal facing the plug connector

5.2 Power supply

Power supply to the valves is provided through the multi-pin plug connection.

5.3 Activation

Control of the valves is provided solely through the multi-pin plug connection.
 Use a uniform method of control within a multi-pin plug. Preferably, all control

signals should be positive switching (shared supply cable at 0 V); otherwise all
control signals are negative-switching (shared supply cable at 24 V). Control in
mixed operation is not permissible!

 If flat cables are used:

Use plug connector in accordance with IEC 60603-13 with long interlock.
Connect all 0 V-/24 V supply cables. If the technical implementation does not
permit use of all 0 V/24 V supply cables, contact a Festo technical consultant.

 If terminal strips are used:

Install all lines/supply cables together, for example as a cable harness or in a
cable channel, to prevent malfunctions. Mixed operation is not permissible!
