8.4 ADJUSTEMENT/CALIBRATION OF THE DROPSA OPTILEV OPTICAL LEVEL (on selected models)
The level is tested and calibrated with oil by Dropsa, however is recommended before starting the pump to follow the procedure
below:
1) Fill the reservoir;
2) Open the front regulating hole;
3) Turn the level adjustment screw using a screwdriver,
until the green led on the level is off (see the image
below);
4) Turn the screw in the opposite direction until the
minimum signal level disappearance on the display (or
the green LED for manual versions).
At the end of this procedure the level is correctly set. It is possible to re-do the calibration following the same procedure above.
8.5 OPERATING MODE FOR AUTOMATIC VERSIONS
For automatic version, you can set two different operating modes: CYCLE or PULSE as described below:
8.5.1 "CYCLE" Mode
In Cycle mode if you use a
timer,the lubrication cycle will
be completed when the timer
ends. The Cycle will complete
when the timer expires or the
pressure is reached. The
Standby phase is determined
by a timer or by an external
input counter.
8.5.2 "PULSE" MODE
In Pulsemode, the duration of
the Standby Phase and the
Lubrication Phase are both
determined by an external
signal counter. The correct
operation of the Lubrication
Cycle can be monitored using a
cycle sensor. This mode is
typically used for conveyor or
chain lubrication where the
duration of the lubrication
cycle is determined by an
external pulse.
Lubrication Phase can be
repeated
Example 4) Standby determined by a counter. Alarm signal given if the
external counter signals not detected within a set time.
Example 1) Standby and Lubrication determined by ON & OFF
Timer
Example 2) Standby determined by a counter
Example 3) Standby determined by a counter and timer
combination.
Example:
Standby Phase determined by the Pause Counter, and
lubrication Phase determined by Cycle Counter.
[CYCLE Cnt>1 PAUSE Cnt>0 ]
The Lubrication Phase is Suspended if no external
signals are recieved within a time specified by the
suspend Timer.
[SUSPEND T>0 ]
