Reply to Bradley6969. Override. It is sometimes necessary to limit a variable in order to maintain safe operation or protect process equipment. If this variable is a function of the system's primary controlled variable, the two variables can be interlocked in an override system. The primary variable maintains control as long as the second variable does not exceed filexlib. A manual override (MO) or manual analog override (MAO) is a mechanism where control is taken from an automated system and given to the user. For example, a manual override in photography refers to the ability for the human photographer to turn off the automatic aperture sizing, automatic focusing , or any other automated system on the camera. override ( overrode pt) ( overridden pp ) vt [+order, objection, decision] passer outre à → As managing director, he will be able to override their decisions.

HVAC fan manual override switch. Thread starter Franspagnolais127; Start date May 16, 2007; F. Franspagnolais127 Member. philadelphia. United States, English May 16, 2007 #1 Bon jour! I am an engineer working on a project and I need a translation for the following technical term: HVAC fan manual override switch.
With a manual override feature that allows you to bypass the motion sensor completely and manually control the motion sensor light switch like a good old wall switch, all your problems are solved. Manual override is the key to having the best of both worlds without the drawbacks of either motion-activated or manual switches. The manual override feature we are talking about here is a permanent override, not a temporary bypass.
I also have a button setup on my bread board where I want to take priority or have a manual switch to turn on if needed before the loop takes over. ( Right now I have to wait till the Void setup code finishes, then in the loop I have the buttons setup so I can manually crush up and down using the actuator)
However, several Contracting Parties suggested that, concerning the manual override, the switching OFF has the highest priority with regard to safety. UN-2 Many ESC systems have an "off" override switch so the driver can disable ESC, which may be desirable when badly stuck in mud or snow, or driving on a beach, or if using a smaller-sized spare tire which would interfere with the sensors.
My initial concern was even if they only wanted to override the timer to perm on (and use a normal 1g2w switch) then there would be backfeed to the switched side of the timer which could possibly cause damage to the unit so your answer has confirmed my thinking. As you say a 2g switch in series would also have been an option.

The first switch is a dpdt that will activate the manual override, and the second switch will actually operate the light In your drawing manual override looks like two 3-way switches. It will be two buttons. Why just not to put one 3-way switch before transistor? $endgroup$ - user263983. Nov 28, 2020 at 2:58
