Bypass-Specific Parameters
Description
Defines the time from when the bypass is
activated until the M1 (bypass) contactor
is pulled in, and the motor begins to spin.
Enable parameter to the Auto Bypass
feature. If enabled, when a selected fault
(as defined by AutoByp Faults [P3.18.3])
occurs, and the amount of time defined in
AutoBypass Delay (P3.18.4) has passed,
the unit automatically switches to Bypass
mode of operation. The M2 (Output)
contactor opens, the M1 (Bypass)
contactor closes, and line voltage
connects directly to the motor. The motor
spins at full speed.
Defines the authorized faults for the Auto
Bypass feature to activate.
Defines the delay time from when the
drive faults and the bypass is enabled.
Enable parameter to the Essential
Services feature. If enabled, when
activated by Essential Services
(P3.5.1.52), an Essential Services Fault
(83) displays. This is a version of Fire
mode that uses bypass instead of the
drive for controlling the motor. The unit
will automatically switch to Bypass mode
of operation. The M2 (Output) contactor
will be opened, the M1 (Bypass)
contactor will be closed, and line voltage
will be connected directly to the motor.
Motor spins at full speed.
Enable parameter to the Remote Bypass
feature. If enabled, when the unit is
placed in Bypass mode, the M1 (Bypass)
contactor opens/closes in accordance
with Rem. Ctrl. Place (P3.2.1).
