Chapter 1 Product Overview
Status Indication All auxiliary contacts can be programmed as NO or NC for the following states
except External Bypass, which can only be programmed as NO.
Normal/Normal NC: The contact state changes when the unit receives a Start/
Stop signal.
Up-to-Speed/Up-to-Speed NC: The contact state changes when the motor
approaches rated speed, and controls the Bypass switch for 7762 and 7763
configurations in
Figure 3 and Figure 4 .
Alarm/Alarm NC: The contact state changes when an Alarm condition is
detected.
Fault/Fault NC: The contact state changes when a Fault condition is detected.
Network Control/Network Control NC: The contact state is controlled over
the network. (Refer to Table 33 on page 93 , which describes logic command
word to control auxiliary outputs.)
External Bypass: This contact controls the Bypass switch for MV applications
with the 7760 configuration in Figure 1 .
Note: The tag name without a suffix indicates a NO state (e.g., Normal). On the
other hand, a tag name followed by NC indicates a normally close state (e.g.,
Normal NC).

Note:
• The Aux #1 contact is always programmed Up-to-speed for 7762 and
7763 applications, or External Bypass (N.O.) for 7760 applications to
control the bypass circuit breaker/contactor.
• The Aux #2 contact is typically programmed for fault indication (it can be
configured for N.O./N.C.).
• The Aux #3 contact is typically programmed for alarm indication (it can
be configured for N.O./N.C.).
