When JMP503 is set to the RESTART position as shown in
Figure 15 below (factory set to UV trip), the drive will stop
when an under voltage condition, (bus voltage drops below
200 VDC), occurs. This can occur due to line sag, line
transients, or line disconnect. A timer, (1.5 seconds), is
started which allows an automatic restart if the bus voltage
has returned to proper operation potential. Refer to Figure
4 (page 4) for Jumper Locations.
