The user can select the following Open and Close sequences:
. Open: the Open coil is driven. In case of four coils, the selected Open coil phase is driven.
. Close: the Close coil is driven.
. OC: In sequence, the Open and Close coils are driven. In case of four coils, the selected Open coil
phase is driven.
. CO: In sequence, the Close and Open coils are driven. In case of four coils, the selected Open coil
phase is driven.
. OCO: In sequence, the Open, the Close and then again the Open coils are driven. In case of four
coils, the first Open command is issued on the selected Open coil phase, while the second Open
command is issued on all coil phases.
Via the software, it is possible to repeat an OC or CO command up to 9999 times.
These sequences are also selected by means of a dedicated pushbutton; the selected sequence is
confirmed by an LED.
For all the above sequences, the user can program the following delays:
. Open command duration: range 10 ms to 10 s.
. Close command duration: range 10 ms to 10 s.
. Open to Close delay: delay range 10 ms to 199.990 s.
. Close to Open delay: delay range 10 ms to 199.990 s.
. Recording duration: range 10 ms to 199.990 s.
. After programming, it is possible to view on the display the sequence timing: this helps avoiding
programming errors.

TATIC RESISTANCE MEASUREMENT
(OPTIONAL)
This measurement is performed connecting CBA2000 to the test sample and measuring its
resistance. Test samples can be: joints, main contacts and so on. Main contacts resistance is
measured in the closed position.
. Test current, resistance measuring range, resolution and accuracy: see the table.
