 AVERTISSEMENT

Risque de décharge électrique.

Débrancher l'alimentation avant de réaliser tout

raccordement électrique. Le circuit imprimé et

ses composants présentent une tension CA. Tout

contact avec des composants porteurs de tensions

dangereuses risque d'entraîner une décharge

électrique et de provoquer des blessures graves, voire

mortelles.

Important:

• Use the M4 x 8 crosshead terminal screws

provided. Substitution of other screws voids the

warranty and agency approvals.

• To prevent moisture from entering and

condensate from forming inside the Type 3R/IP43

enclosure, do not block the drain hole provided.

• To prevent moisture from entering and

condensate from forming inside the Type 4/IP67

enclosure, do not remove the case-to-cover O-ring

provided on the flow switch.

• Use copper conductors only. Make all wiring in

accordance with local, national, and regional

regulations.

• Do not exceed the control’s electrical ratings.

Exceeding the control’s electrical ratings can

result in permanent damage to the control and

void any warranty.

The F261 models have three color-coded terminals. Red is

common. See Figure 11 and Table 5 for switch action.

Setup and adjustments

 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.

 ATTENTION

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.

 ATTENTION

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.

To adjust the setting of the flow switch:

1.  Disconnect the power supply before making any

electrical connections.

2.  Remove the enclosure cover.
