2.3.2.3 Electrical connection - frequency output (version FC01-LQ-U1T4)
The quantity-dependent pulse may be selected in the menu item “DISPLAY SELECT”. A square
pulse signal is available for driving a counter or a primary control at the plug XAH /BUSY E/- and
/BUSY C/+ (pins 3 and 4) (see fig. 16 - circuit diagram FC01-LQ - transistor outputs).
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.
The shield cables can be connected to connector XAS, pin 3.
Electronic signal processing (fig. 17)
If the frequency output of the FC01-LQ is connected to an electronic counter, computer or PLC,
the load current should not exceed 10 mA so as to ensure low level is 0.8 V. The max. admissible
voltage level of 48 V is irrelevant in this connection.
Typical circuit (example 1)
