F263 Series Liquid Level Switches Installation Instructions
5
Setup and Adjustments
Checkout Procedure
Before applying power, ensure that installation and wiring connections are made to job specifications.
After making all necessary adjustments and electrical connections, put the system into operation and observe at
least three complete operation cycles before leaving the installation site.
Operation
The F263 Float Switch controls water levels to within approximately 1/2 in. (13 mm).
When the liquid level falls approximately 1/2 in. (13mm) below the height at which the switch is installed, the switch
closes the red contact (common) to the blue contact. See Figure 6 and Figure 7.
!
CAUTION: Risk of Property Damage.
Do not set the switch lower than the factory setting. The switch is factory set at
approximately the minimum flow rate. A lower setting may result in the switch failing to
return to a no-flow position which may result in damage to the controlled equipment or other
property.
MISE EN GARDE : Risque de dégâts matériels.
Ne pas régler le commutateur sur une valeur inférieure au paramètre d'usine. Le
commutateur est réglé en usine sur une valeur correspondant environ au débit minimum.
Un réglage sur une valeur inférieure risque d'empêcher le commutateur de revenir sur une
position « aucun-débit », ce qui risque d'endommager l'équipement contrôlé ou de
provoquer d'autres dégâts matériels.
!
CAUTION: Risk of Property Damage.
Do not attempt to change sealed settings. Attempted adjustment may damage the control
or cause loss of calibration or other property damage.
MISE EN GARDE : Risque de dégâts matériels.
Ne pas essayer de modifier la position des éléments de réglage bloqués. Toute tentative de
réglage risque d'endommager le dispositif de contrôle ou de provoquer la perte des valeurs
d'étalonnage ou d'autres dégâts matériels.
IMPORTANT:
All F263 switches are factory-set and factory-sealed.
Do not
attempt to change the factory
settings. Changing the factory settings voids the warranty.
