Detenting actuation of the manual override (manual reset)
Operation Valve response
• Use a screwdriver (max. blade
width 3 mm) to press down the
plunger of the manual override
until the valve switches.
• Then turn the plunger in a
clockwise direction one fourth of a
turn.
The pilot v alve switches and controls
the power valve in the switching
position.
• Remove the screwdriver. The v alve maintains the switching
position.
• With the screwdriver, turn the
plunger one fourth of a turn
anti-clockwise.
• Remove the screwdriver.
The spring force presses the plunger
of the HH N into the basic setting.
The pilot valve returns to its neutral
position and thus also the power
v alve (not for impulse valve,
ident. code J).
