User’s manual for screw-conveyor feeder Quatro PSQ
2.4. Feeder protections
PSQ feeder is protected against pulling back of the heat to the container by:
• Temperature sensor for endless screw located in the controller. This sensor should precisely
adhere on whole measuring length to the socket on the pipe of the feeder.
• one-function cooling valve (so-called fi re- fi ghter), equipped with a bimetal temperature sen-
sor inserted into a dedicated socket in the feeder and connector G1/2” on fl exible hose screwed
with a G1/2” connector to the feeder pipe.
Note! Remember about fi lling a ball of the “ fi re- fi ghter” with water.
2.5. Motoreducer and fan
Motoreducer of the PSQ feeder is protected with a split pin (M5 screw, class 5.8) protecting it against
overloading and it transfers torque to the screw. Before each start-up, you should:
• check whether the split pin is at its location,
• connect plug of the motoreducer and fan to the controller,
• activate the corresponding direction of feeding rotations using the switch on a box of the
motor.
