Warning
Before actuating the manual override:
Uncontrolled actuation of the valve coils can cause the
actuators to perform sudden unexpected movements
which may cause injury to human beings and damage to
property.
·
Disconnect the power supply for the valve solenoid coils
at the relevant connections on the MPA−S valve terminal.
You will thereby avoid undesired actuation of the valve
coils.
Before switching on the power supply:
During commissioning, manual override functions which
are in the switched state can cause actuators to perform
sudden unexpected movements. These movements can
cause injury to human beings and damage to property.
·
Make sure that all manual override actuations are reset
to their basic positions.
You will thereby avoid undefined switching states of the
valves.
Proceed as follows:
Warning
Before testing the valve−actuator combination:
make sure that nobody is in the danger zone.
Note
A valve which has been switched by an electric signal,
cannot be reset by the manual override. The electric signal
is dominant in this case.
·
Reset the electric signal before actuating the manual
override.
