5-5.1 Trip Latch Overlap Adjustment
Figure 5-5a shows a composite view of the shunt trip lever
and the trip latch, as described in Paragraph 4-4. The angular
position of the trip shaft latch surface is adjustable in relation
to the trip latch surface. This adjustment is made possible
by a screw located in the top of the actuator frame (Figure
5-5b).
The proper adjustment procedure is as follows:
1. Close the breaker.
2. Slowly rotate the adjusting screw clockwise until the
breaker trips. This is the “no overlap” position.
3. Conclude by rotating the adjusting screw four turns in a
counterclockwise direction.
5-5.2 Breaker Open Position Stop Adjustment (DSII-632
Only)
The proper adjust procedure is as follows:
1. Refer to Figure 5-6.
2. Open the breaker and loosen the open position stop bolt
nuts so that the eccentric cylinders can be turned by hand
but will stay put.
