The M9203-xxB-x models include one integral auxiliary switch with a switch adjuster accessible on either face of
the actuator (see Figure 2 and Figure 3). The factory setting for the Auxiliary Switch is 11° closing (relative to the
0 to 90° rotation range as printed on the product label). See the Technical Specifications table for the auxiliary
switch ratings.
WARNING: Risk of Electric Shock and Property Damage.
!
Insulate and secure each unused wire lead before applying power to the actuator. Failure to insulate
and secure each unused wire lead may result in property damage, electric shock, and severe personal
injury or death.
AVERTISSEMENT : Risque de décharge électrique et dégâts matériels.
Isoler et protéger chaque fil non utilisé avant de mettre l'actuator sous tension. Le non-respect de cette
obligation d'isolation et de protection de chaque fil non utilisé risque d'entraîner des dégâts matériels,
des décharges électriques et des blessures graves, voire mortelles.
The switch point is continuously adjustable through the actuator's rotation range. For the most accurate switch
positioning, see Figure 12 and use the method in the following example.
To change the switch point, proceed as follows:
1. Position the actuator in the full spring return position.
Note: The switch is factory set to trip when the actuator reaches the 11° position.
