6.4.3 Automatic calibration

Automatic calibration begins during operation
for all active outlets if a corresponding event
occurs (Table 1, page 44).
By default, the micro-dosage system is set to
automatic calibration. It can be deactivated via
DIP switch 4 (Chapter 6.2.1, Table A, page
Deactivation of automatic calibration is useful
only in few cases, for example if air pressure
and temperature are constant, or for special
tests in which the quantity of lubricant deliv-
ered should not be influenced by the calibra-
tion process.

See Figures 8 to 10
The machining parameters of machine tool
spindles can vary in the machining process.
The spindle bearings are therefore subjected
to different loads. The optimal amount of lu-
47). bricant required for the bearings can vary de-
pending on the particular load condition.Via
the enable input, the micro-metering unit
provides the ability to influence the quantity of
lubricant delivered in the ongoing lubrication
operation.
If the enable signal is constantly active, the
MDU delivers the set (maximum) volumetric
flow at its outlets (see Figure 8).
