Input (start) signal
The Dual TrueFeed needs an input signal from the production machine in order to operate.
Two different input signals can be used to control the Dual TrueFeed.
1. A potential free relay contact.
Use the white and brown wire for the potential free contact.
2. A relay signal up to 30 Volt DC.
In case of a powered relay signal, connect the white wire to +24 VDC and the yellow wire to
the side. To detect a start signal, the TrueFeed needs a minimum voltage of 18 VDC.
Configuration: Input filter
The "Input filter" setting is only visible when "Relay" is selected as the Input mode.
In the Relay Input mode the length of the feeding time is measured automatically by the duration of the
incoming input signal. The Input filter calculates the average feeding time of the set number of shots (3-32)
The calculated average time is used as steady feeding time. The default Input filter setting is 3.
During production, if a production setting was changed or if the "Stop/Start" button was pressed, the feeding time will
reset automatically.
Configuration: Fill. System
Filling system, NO (None), ME, MV or GR (see Section 7.7)
Configuration: Filling start
Function: When it is detected that the hopper weight is 800 grams (default) or less, the filling system will
automatically start. The default value can be manually changed if necessary (depending on the material
properties).
This function is only visible when a filling system is selected.
Configuration: Hopper empty
The system will give a "Low Hopper Level" message if there is less then 700 grams (default) of material in the
hopper. For this system to work correctly it is necessary to calibrate the loadcell with an empty hopper and the
hopper lid in place. This system will always be active. The default value can be manually changed if necessary
(depending on the material properties).
Regrind HL
High level of the Regrind hopper. This is the weight of Regrind hopper when the hopper is filled to its maximum
capacity. (Default is 2000 grams)
Regrind lvl4
Maximum Regrind feeding percentage (Level 4 of the Regrind hopper). This value will be added to the
Regrind % setting on the Production screen. (Default is 20%)
Input mode is not visible in RPM Production Mode. (Timer is used automatically)
