Note
Incorrect actuation of the non-detenting manual override can result in malfunctions or
damage to the manual override.
To actuate the manual override, use a blunt plastic pin (max.

6.5 mm), for ex­
ample. In this way, you avoid damaging the plastic of the MO.
Operate the manual override with max. 25 N.
If the manual override is in the actuated state, it is not possible to reset the valve to its
neutral position with an electric signal. The manual override is dominant in this case.
Non-detenting operation of the manual override (reset: automatic)
Operation Valve response
Press in the plunger of the MO,
for example, with a blunt plastic
pin (max.

6.5 mm), until the
valve switches.
The pilot valve switches and actuates
the valve into the switching position.
Hold down the plunger of the MO. The valve remains switched.
Put down the plastic pin. The spring force presses the plunger of
the MO back to the normal position.
The pilot valve returns to the normal
position, and so, too, does the mono­
stable power valve (not for bistable
valves, code J).
