Penn F61 Series Installation Manual

Installation
Important: Use this F61 Series Standard Flow Switch only to control equipment under
normal operating conditions. Where failure or malfunction of the flow switch could lead to
personal injury or property damage to the controlled equipment or other property, additional
precautions must be designed into the control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of
or protect against failure or malfunction of the flow switch.
Important : Utiliser ce F61 Series Standard Flow Switch uniquement pour commander des
équipements dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou
un dysfonctionnement du flow switch risque de provoquer des blessures ou d'endommager
l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit
intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon
permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des
dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en
cas de défaillance ou de dysfonctionnement du flow switch.
Some models of the F61 Series Standard Flow Switches require installation or adjustment of
paddles prior to mounting. See

Installing the Flow Paddles
Important: To allow the switch to detect changes in the fluid flow, the flow paddle must not
touch the pipe or any restrictions in the pipe.
Adjust flow paddles to the size of the pipe used. If needed, trim the large flow paddle at the arc
corresponding to pipe size (see Figure 1 and Figure 2) and install.
