3.3 Function
The manual application unit consists of a rigid part permanently connected with the heat-
able hose and a rotating part.
The part connected with the heatable hose contains
• the heater,
• the temperature sensor, and
• all electrical connections.
The rotating part has
• the nozzle system,
• the trigger,
• the sender,
• the triggering safeguard
• the removable battery (lithium cell) for the power supply of the transmission electronics
and
• the coding switch for setting up the device address.
The hot melt material flows through the connection fitting (2) of the heatable hose into the
heating cylinder (9) that is heated by the heating cartridge (8).
The hot melt material flows into the nozzle head from there. In its idle state, the nozzle
needle (15) closes the nozzle holder (13), or the swirl nozzle.
When the trigger is activated, the nozzle needle opens the nozzle holder/swirl nozzle
and the hot melt material is discharged. The transmitter is activated at the same time and
transmits the activation of the trigger to the basic unit so that the pump can be controlled
as needed. A non-contacting and therefore wear-free magnet activates the transmitter.
The temperature of the heating element is constantly monitored by the temperature sen-
sor (6) and transferred to the control electronics in the basic unit. The control electronics
use the information to control the heating cartridge.
3.4 Special features
General
• The rotating part can be turned endlessly around the stationary part.
• No obstructing cables on the outside of the manual application unit due to wireless
transmission of the trigger signal.
• The triggering safeguard (22) locks the trigger by moving up and down.
Spray version
• The spray air is pre-heated in the heating hose/cylinder (1 resp. 9) and is discharged
time-shifted (preliminary and secondary air). This ensures an optimal, drip-free spra-
ying pattern.
• The spray application can be converted to extrusion application at any time by using an
adapter.
