GE CS300 manual USE of S4 and S5 DIP Switch, USE of CV Jumper, AC Mains frequency

CS300

1)Set all the switches in off position (18-seconds ramp time), use a current probe able to detect a current peak ≤ 10mS between the C or D terminal of the DC-LINK.

2)At this point read the measuring of the maximum peak current present on the DC-LINK during the precharging phase.

3)If the measured peak current is much lower than twice the value of the CS300 rated current, it is possible to select the switch for a lower ramp time (SW3.4 - 8- second ramp time). Go back to point 2.

Such operation will be repeated till the measured peak current is equal or lower than twice the value of the converter rated current.

3.5 USE OF S4 AND S5 DIP SWITCH

The S4 and S5 dip switches are used to select the AC mains frequency.

AC Mains frequency	S4	S5
50 Hz (Default)	OFF	OFF
60 Hz	ON	ON

3.6 USE OF CV JUMPER

(See the ML signal function)

With “CV” jumper mounted (on), the signal available on the terminal 36 will be LOW with AC mains voltage lower than the undervoltage threshold (see figure 3). It will be HIGH, with AC mains voltage higher than the undervoltage threshold.

With “CV” jumper open (off), the signal on the terminal 36 will indicate, with an impulse of about 150ms, (low level signal) that the power supply voltage has had a transition at a level lower than the undervoltage threshold.
