START-UPS
WarnIng
risk of injury from improper operation.
Improper operation may result in injuries as well as damage to
the device and its environment.
▶ Before start-up, ensure that the operating personnel are
familiar with and completely understand the contents of the
operating instructions.
▶ Observe safety instructions and information on intended use.
▶ Only adequately trained technicians may start up the device.
risk of injury due to an incorrectly functioning system.
Before start-up, carry out tests to ensure correct functioning of
the system. This helps to avoid personal injury and damage to
the system during operation.
▶ Before final system start-up, carry out a full function test and
the required safety tests.
▶ Plan foreseeable possible faults in the tests.
Configuration must be fully completed to start up the equipment.

Electrical start-up
CauTIon
Undefined reaction of the valves.
The reaction of the valves is undefined if the supply voltage
is too low. This may result in unintentional processes in the
system.
▶ Ensure that the level of supply voltage is above the low toler-
ance limit (see "14.4 Electrical data").
risk of injury due to hot surfaces.
A longer duty cycle may result in the valves becoming hot.
▶ Let the valves cool down before removing them or wear
heat-resistant protective gloves.
When using UL-certified device versions with 2x3/2-way
valves, Type 6524:
▶ If switching occurs frequently, leave at least 100 ms pause
before switching on again.
Feedback about sufficient supply voltage is displayed at the
valve block via the PWR LEDs (connection units PSU-L... and all
PQ modules).
If diagnostics has been activated, a diagnostics message occurs
via SIMATIC ET 200SP / SP HA.
procedures before electrical start-up:
→ Check the connections.
→ Check supply voltage.
→ Set manual overrides of the valves in neutral position.
