CD-20SFA Sample Probe Controller
Note The input pulse contact must be closed for at least 5 msec to produce a start pulse. An electronic
square wave input must have a pulse amplitude of 12VDC. A 5VDC square wave will not work.

3. Connect the sample failure alarm relay contact to 1TB-3 and 1TB-4. The contact will remain open for as
long as sampling occurs within the alarm delay period. This contact is rated for 90 VA resistive and 30 VA
inductive loads. It is suitable for use with 115VAC low current.
4. Adjust the alarm delay time by turning the R1 potentiometer screw clockwise. Alarm delays ranging from
5 seconds to 6 minutes can be selected via this adjustment.
