Step 8 - Verify the Setup and Adjust Switches if Required

8-7

8.3.3 Relay Control Output - Running or Faulted (Position 3)

The switch at position 3 specifies the type of status indication provided by the normally
open (N.O.) relay control output (control terminals 19 and 20). See section 7.3 for a
description of control terminals 19 and 20. The relay can be used to indicate that the
unit is running (power is applied to the motor section) or has faulted (an active drive
fault exists).

Settings (Position 3):

OFF position = Unit Running Indication (Default)
ON position = Unit Faulted Indication

8.3.4 Auto Restart (Position 4)

The switch at position 4 enables or disables the auto-restart function. If the
auto-restart function is enabled, the unit shuts down as usual upon the detection of a
fault, waits five seconds, and attempts to start automatically. If the fault reoccurs, the
drive section again waits five seconds before trying to start, up to a maximum of four
attempts within a five minute period. If the drive section fails all these attempts, it
remains in the faulted state and displays the fault it is attempting to clear.

While the unit is counting down the five-second restart period, the display flashes the
following pattern to warn of the impending automatic restart of the drive:

.....

If the Reset input is asserted (or the

key is pressed) during the countdown, the

auto-restart process is canceled. Table 8.1 lists the auto-restartable faults.

ATTENTION: Enabling this feature causes the unit to restart
automatically after auto-restartable faults (see table 8.1) have shut down
the unit. When this feature is enabled, the user must ensure that
automatic restart of the driven equipment will not cause injury to
operating personnel or damage to the driven equipment. Failure to
observe this precaution could result in severe bodily injury or loss of life.
