INSTALLATION
3-10
- Use the tension system, with the tension spring, which incorporates
the bracket for the encoder conveyor. To achieve the tension, place
gently in the final position and rotate the arm, tensioning it forward
(anti-clockwise, looking from the side of the wheel). Maintain in this
position and tighten the screw.
- Do not overtighten. There must always be some slight slack to allow for
small variations on the surface.
- Place the encoder on smooth surfaces, free of joints or protuberances
that may cause the contact wheel to jump with the conveyor and
therefore ‘lose’ reading pulses.
- For an encoder mounted with a coupling on the shaft, the elastic
coupling hole is 10 mm in diameter.
- When mounting on a shaft, the parameter of pulses per meter must be
configured for correct operation.
- The operating values of the encoder are defined in each installation; for
this, follow the instructions provided in section ‘4. Use’.
To connect other types of encoders, consult your Focke Meler Representative
or the Focke Meler Main Office.
Pressure regulator
The 0-10 V output is used when required:
- Control of the pneumatic supply pressure of the application pump
(piston pumps).
- Control of the pressure of the by-pass valve (gear pumps) to, depending
on the speed of the machine, apply the necessary hot-melt flow or
maintain the circuit pressure at the desired value.
For this, there is a pneumatic pressure regulation system (or proportional
valve VP-200) that transforms the output voltage of the controller (0-10 Vdc)
into the corresponding pneumatic pressure of the pump or of the by-pass
valve (0-6 bar).
The correspondence is linear between the established sections, being able to
program up to 5 different sections.
The VP-200 regulator itself has its own setting and programming mode. See
the instructions for use for it.
This peripheral needs 24 Vdc power supply, provided by the controller through
the 0-10 V connection of output 4.2 (see the Introduction chapter, page 2.5)
and needs a pneumatic power supply (max. 10 bar), through a built-in filter
of 5 µ. The VP-200 has a display that shows the existing pressure at any given
moment.
