2 .2 .2 .3 Electrical connection - pulse output (version FC100-CA-U1T4...)

The quantity-dependent pulse may be selected in the menu item "USER OUTPUTS" (see chapter
5.9). A square pulse signal is available for driving a counter of a primary control at the plug XAH /
BUSY E/- and /BUSY C/+ (pins 3 and 4) (see fig. 19 - circuit diagram FC100-CA - transistor out-
puts).
Signal ground shall be connected to pin 3 (BUSY E/-) and the driving load to pin 4 (BUSY C/+).
The pulse length is 50 ms (±1%) continuously.

Select cable size ≤1.5 mm to make the connections.
Electronic signal processing (see fig. 20)
If the frequency output of the FC100-CA is connected to an electronic counter, computer or PLC,
the load current should not exceed 10 mA to ensure low level is 0.8 V.
