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
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
, which describes logic command
word to control auxiliary outputs)
External Bypass:
This contact controls the Bypass contactor for MV
applications.
Figure 16 - Control Terminals
Note:
•
The Aux #1 contact is always programmed for External Bypass (NO) to
control the bypass contactor in MV applications.
•
The Aux #2 contact is typically programmed for fault indication in MV
applications (it can be configured for NO/NC).
•
The Aux #3 contact is typically programmed for alarm indication in MV
applications (it can be configured for NO/NC).
•
The Aux #4 contact is always configured as Normal (NO) to control the
line contactor for MV applications.
TIP
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 closed state (e.g. Normal
NC).
