Solid State Outputs M (RUN) When controller is operating, the RUN contact is closed.
Um = 100% When motor is running at 100% of line voltage (after starting is
complete), the Um contact is closed.
FAULT The FAULT contact closes for: an EEPROM error; a line voltage
phase loss; or a shorted thyristor. Refer to paragraph 6.1 re
SW1-4 settings.
Recommended Fuse Style * Two levels of short circuit protection can be provided by the user:
1. Type 1 protection is available where the short circuit protective device protects
the wiring and the integrity enclosure. The controller will probably damage and
require replacement or repair befoe being re-energized. Cirucit breakers and
motor circuit protectors provide this type of protection.
2. Type 2 protection is available where the short circuit protective device protects
both the wiring and the controller. The controller should not require repair
before re-energizing after the short circuit has been cleared. Fuses of an KR-1
type or HRC-1 type sized in accordance with the NEC/CEC code or semicon-
ductor type fuses provide this kind of protection.
