The symbol |

Above I2, the S2Ca ceases to operate. Between I1 and I2 the stroke rate is between F1 and F2, proportional to the signal current.
Upper band: |
|
The signal | appears in the LCD display. The S2Ca will cease to operate below I1. |
Above I2, the S2Ca will operate at F2. Between I1 and I2 the stroke rate between is F1 and F2, proportional to the signal current.
The smallest processable difference between I1 and I2 is 4 mA.
Error processing In the “ER” (error) menu option you can activate an error processing function for the “curve” mode. An error message appears for signals below 3.8 mA and the S2Ca stops.
7.4.3Settings for ÒcontactÓ operating mode (CONTCT menu)
In addition to those settings menus described in 7.5, there is an additional CONTCT in the overall SET menu for the “contact” operating mode.
The operating mode “contact” allows you to activate a single stroke or a series of strokes. The strokes can be activated by a pulse or via the “external control” terminal. This operating mode is intended to transfer input pulses into a reduction (fraction) or small increase in strokes.
IMPORTANT
The factor resets to Ò1Ó if you change to a different operating mode.tity cod
