The Keypad
890CS Common Bus Supply - Frames B & D; 890CD Common Bus Drive and 890SD Standalone Drive - Frames B, C & D
Alert Message Displays
A message will be displayed on the Keypad when either:
♦ A requested operation is not allowed
♦ The drive has tripped
Most messages are displayed for only a short period, or for as long as an illegal operation is tried, however,
trip messages must be acknowledged by pressing the E key.
Experience will show how to avoid most messages. Refer to Chapter 11: “Trips and Fault Finding” for trip
messages and reasons.
