E-Clipse bypass functions overview
Advanced Override Mode (Override 2)
In the Advanced Override (Override 2) mode, the motor is powered either by the
drive through the drive or by AC line power through the bypass contactor.
Depending on the E-Clipse bypass parameter 1708 setting, the user can switch to
the Advanced Override mode by closing the Advanced Override input contact (DI5 -
if programmed) or as a command through communications.
When Advanced Override is active, the system does not respond to the inputs on the
Drive and E-Clipse Bypass control panel keys.
The Motor Run LED flashes green on the drive and bypass keypads when the
system is in override.
While in Advanced Override, the system responds to bypass overloads and
programmed faults. The system can be custom programmed to acknowledge or
disregard certain faults, safeties and enables. The unit default is programmed to
ignore all external safeties and run enables. See Group 17 for programmability of the
digital input and fault functions.
Normally when the Advanced Override is deactivated, the system returns to the
previous operating mode and can be controlled using the Drive and Bypass
keypads. If the system was previously in
Hand
mode, the system reverts to
Off
mode. The exception to this is when the Smoke Control (Override 1) input contact is
closed, in which case the system remains in Smoke Control mode.
The tables on pages
provide information on how to set up the E-Clipse bypass
and the ACH580 drive for Override 2 mode. The table on page
Override 2 parameters in the E-Clipse bypass. The table on page
describes the
key Override parameters that would be programmed in the ACH580 drive.
describes how to configure Override in the ACH580 drive
using Primary Settings, instead of using parameters. In most Override 2 applications
the Primary Settings (page
) will be used to program Override 2 applications.
Note that programming ACH580 drive Override parameters / Primary Settings is not
necessary if E-Clipse bypass parameter 1708 is set to [1] Bypass or [4] Stop. The
tables on pages
and
assume the ACH580 drive is in Scalar mode.
