Testing and startup

5.1 Manual override
The valve control's functional reliability and method of
operation can be checked before start-up by activating the valve
positions using the manual override instead of the electrical
signal. The electrical signal is disabled when the manual
override is used.
1 or 2 manual overrides depending on the valve model
(with 1 or 2 solenoids), can be operated independently of each
other in 2×3/2 valve units:
Turn and detent:
Put the screwdriver into the manual override's groove and turn
it to position 1 from the zero position using slight force until it
clicks into place. The valve switches and remains in the
switched position until the manual override is turned back to the
zero position.
Turn:
Put the screwdriver into the manual override's groove and turn
it to position 1 from the zero position using slight force.
The valve switches. The valve returns to the zero position when
released.
