start the motor when the bypass has been
selected as the power source for the motor.
The Off/Reset key may be used to manually
stop the motor if the motor is running on
bypass power. The Off/Reset key also
resets most bypass Faults. It may take

reset after an overload trip. If a bypass fault
condition is present, the second push of the
Off/Reset key puts the bypass in the Off

Fig. 127 — Bypass Control Keypad Description
SMOKE CONTROL MODE — In the Smoke Control (Over-
ride 1) mode, the motor is powered by AC line power through
the bypass contactor. The source of the Smoke Control com-
mand is DI 6 and is unaffected by external stop commands. The
VFD Keypad and the Bypass Keypad will not accept user com-
mands when the system is in Smoke Control mode (the keypad
user inputs are disabled). The user can switch to the Smoke Con-
trol mode by closing the Smoke Control input contact (DI 6).
When the Smoke Control input contact is closed, the system is

DESCRIPTION
forced to bypass and runs the motor. The Motor Run LED flash-
es green when the system is in override. While in Smoke Con-
trol, the system only responds to certain inputs. Normally, when
the Smoke Control input contact is switched from closed to open,
the system returns to the operating mode that existed prior to en-
tering Smoke Control and can once again be controlled using the
Drive and Bypass keys. The exception to this is when the Bypass
Override (Override 2) input contact is closed, in which case the
system switches to Bypass Override operation. See Fig. 128 for
typical wiring diagram.

PROGRAMMABLE RELAY CONTACT OUTPUTS —
The ABB E-Clipse bypass has 5 programmable relay outputs
as standard, see Fig. 126. The default programming descriptions
for these relay outputs is described below.
BYPASS NOT FAULTED — The Bypass Not Faulted relay is
energized during normal operation. The Bypass Not Faulted re-
lay is de-energized when a bypass fault has occurred.
SYSTEM RUNNING — The System Running relay is ener-
gized when the ABB E-Clipse bypass System is running. The
System Running relay provides an output when the motor is run-
ning whether powered by the ACH550 drive or the bypass.
SYSTEM STARTED — The System Started relay is energized
when the ABB E-Clipse bypass system is started. Three condi-
tions must be met in order for the relay to energize:
1. A Start command must be present
2. The Safety Interlock input contact must be closed and
3. There can be no fault present in the system
BYPASS SELECTED — Relay output four is factory default
programmed for Bypass Selected. The relay will be energized
anytime the user has placed the system in Bypass Mode.
BYPASS AUTO — Relay Output five is factory default pro-
grammed for Bypass Auto. The relay will be energized anytime
the user has placed the bypass in the Auto mode.
The complete list of programmable relay output functions
follows:
0 = NOT SEL
1 = SYS READY
2 = SYS RUNNING
3 = SYS STARTED
4 = BYPASS SEL
5 = BYPASS RUN
6 = BYPASS FLT
7 = BYP NOT FLT
8 = BYPASS ALRM
