Theory of Operation

The Rotorspray 97115 is clamped in a fixture. The dispensing valve is clamped in the holder of
the rotorspray so that the tip of the flexible dispensing needle is directed to the inside of the
wetting holes on the rotor disk.
The LOCTITE Controller 97153/97204 or the Controller 97152 must control:
®
– Switching on of the rotorspray.
– The preselected dispensing time after the rated rotor speed is reached.
– Switching off of the rotorspray.
As long as the dispensing valve is open, the product is dispensed through the wetting holes by
centrifugal force and uniformly distributed onto the cylindrical inner surface of the part.
In conjunction with an advancing slide, reaching the end of the advancing movement triggers the
dispensing.
The head of the rotorspray has a longitudinal play of 5 mm. Within this distance, unintentional
contact with an obstacle can be compensated without the rotor disk or the drive assembly and its
shaft being damaged. Furthermore the drive assembly is designed that in case the product flows
back, the drive assembly and the rotor housing do not bond together. With longitudinal play and
the special design of the drive assembly a perfect function is guaranteed.
When a disturbance occurs in a dispensing sequence:
– The dispensing sequence is interrupted.
– The rotorspray is switched off, possibly the advancing slide is switched to moving backwards.
– The Loctite Controller signals an error message with a beeping tone (see Section 7).
