The S1Ca can also run in calibration mode. The corresponding continuous displays show the
current dosing quantities or the feed rate.
The calibration is retained in the event of a change of the set stroke length by up to
±
10
percent (if the stroke length is set to 40% the range is 30% to 50%). If the stroke length is
changed by more than
±
10 percent the yellow warning light lights up, the permanent display
flashes and the flashing “Calib” indicator appears.
IMPORTANT
•
Do not go below 30 % stroke length (SEK type: 50 %).
This will significantly affect accuracy of calibration.
•
Calibration becomes increasingly accurate the more strokes made by the S1Ca
during calibration (recommended: at least 200 strokes).
WARNING
If using a hazardous feed chemical, the following setting instructions ensure
adequate safety precautions have been taken!
Calibration
왘
Insert the suction tube into a measuring cylinder containing the feed chemical - the
discharge tubing must also be correctly installed (operating pressure,…!)
왘
Suck up the feed chemical (press both arrow keys at the same time) when the suction tube
is empty
왘
Note the liquid level in the measuring cylinder and the stroke length
왘
Select the CALIB menu and go the first menu option using the P key
왘
Select “ON” using an arrow key and change to the next menu option using the P key
왘
To commence calibration, press the P key. The S1Ca starts to pump and displays the
number of strokes (“STOP” appears at regular intervals)
왘
After a sufficient number of strokes, stop the S1Ca with the P key
왘
Calculate the dosed quantity (difference between the original quantity and the quantity
remaining)
왘
Enter this quantity in the next menu option and then change to the following menu option
by pressing the P key.
왘
Select the unit (“L” or “gal”) in the “UNIT” menu with an arrow key
The S1Ca is calibrated.
The corresponding continuous displays show the calibrated values.
The total stroke number and total litres are set during calibration to “0”.
The S1Ca is in the STOP status.

The programmable function “auxiliary frequency” allows switching to a different stroke
frequency, which can be set in the AUX menu. It can be activated via the “external control”
terminal. When the auxiliary frequency is activated, “aux” appears in the LCD display.
This auxiliary frequency overrides the current stroke frequency set for the selected operating
mode.
