ACCESSORIES
Fluid couplings can be equipped, beyond the standard fusible plug.
with similar safety devices avoiding oil to escape, and that, in the
case 01 the electronic overload controller, can manage a lew more
palameters too.
The luslble plug is present as an element 01 further safety though
being set al a highel' temperature value.
51 SWITCHING PIN directly fitted 10 the couplíng covel plate
(FIG.9).
The electrical connection of the switch must have a lower
voltage than 230 V and a max current of 6 A (electrical
scheme details reported in FIG. 10).
Fllmly position the cam mounted lelay on its support, so tha!
the dlslance lrom the end 01 the switching prn is 6 mm.
11IS very imporlant to be within such a distance because, in
case the device is activated, the pln comes out owing 10
centrifugal lorce and intelcepts Ihe cam, switch es it on and
gives a conveníent outpul signal (to be used as an alarm or a
blocking impulse for the motor).
Notice that, in the configuratlon 01 an external driving impellel
the sWltching pin works in every condition; while, with an
external dliven Impellel' it can be correctly switched on only in
case of a slip increase due to overload 01 eccesslve load
tOlque absorption.
