5.5 Function of the LEDs
The 800 Dosino is equipped with two green LEDs which display the status
of the dosing drive.
On LED
The upper LED displays the overall status of the 800 Dosino.
The LED lights up The 800 Dosino is connected to a device which is switched on.
The LED does not
light up The 800 Dosino is not connected or the control device is switched off.
Caution
The dosing drive is supplied with electricity for as long as the On LED is
lit. Even if the 800 Dosino is not attached to a dosing unit, the drive pin
on the underside of the dosing drive will still not be able to be adjusted
by hand. If it should happen that it needs to be adjusted, thus making
the attachment of the Dosino on a dosing unit impossible, then the
control device must be switched off. Manual adjustment of the drive
pin is possible only when the On LED is not illuminated.
Status LED
The lower one of the two LEDs of the 800 Dosino shows the respective
operating mode of the dosing drive. The precondition for this is that the
800 Dosino is supplied with electricity, i.e. that the "On" LED lights up.
The LED lights up The 800 Dosino is attached to a dosing unit and ready for operation. It is
only in this configuration that the 800 Dosino can be removed from the
dosing unit.
The LED does not
light up The 800 Dosino is either not attached or not correctly attached to a dos-
ing unit.
The LED flashes
slowly The 800 Dosino is in operation. It doses, fills, is in waiting mode or is cur-
rently extracting the data from the data chip of the dosing unit.
