Electrical start-up of the valve island corresponds to start-up of
the Siemens distributed I/O system SIMATIC ET 200SP / SP HA.
The steps necessary for electrical start-up can be found in the
Siemens system manual "Distributed I/O system ET 200SP" or
"Distributed I/O system ET 200SP HA".
modules with evs
If the functions "Switched off load voltage" and "PRO-
FIenergy" are active, it is not possible to, among other
things, activate the valve positions programmed by the
user.
If the outputs (valves) have been switched off via EVS,
it is displayed in the LC display. Additionally, the output
data sent by the control are also displayed (regular alter-
nating of "EVS active" and "Output data").
10.2 Pneumatic start-up
CauTIon
hazard posed by noise.
Increased noise can be generated when switching pressurized
valves.
▶ Discharge exhaust air via a hose.
▶ Connect a silencer to the exhaust air connection.
▶ Wear ear defenders.

Start-Ups
procedures before pneumatic start-up
→ Check connections, voltage, and operating pressure.
→ Check correct assignment of the connections 1 and 3 / 5.
They may by no means be interchanged.
→ Set manual overrides of the valves in neutral position for elec-
trical operation.
pneumatic start-up
→ Do not exceed maximum operating data values (see type
label).
→ Switch on the supply pressure first.
→ Then switch on the voltage supply.

oPERATIoN
WarnIng
risk of injury from improper use.
Improper operation may result in injuries as well as damage to
the system and its environment.
▶ The operating personnel must know and have understood
the contents of the operating instructions fully.
▶ Observe safety instructions and information on intended use.
▶ Only adequately trained personnel may operate the system.
The valve block is controlled via the SIMATIC ET 200SP / SP HA
interface module.
Device statuses are displayed via LEDs and the LC displays of
the valve units. For details, see chapter "11.3" and "11.4".
