6 - PARAMETER DESCRIPTION
Inline Configuration I/O 24
LCD Display
Range Off, 0 – 10.0 seconds (Default: 3.0)
Description The Inline Configuration parameter controls the behavior of the No Line warning, No Line fault, and the
Ready relay function.
If the Inline Configuration parameter is set to "Off", then the MX
3
assumes that there is no Inline contactor
and that line voltage should be present while stopped. If no line is detected, then a No Line alarm condition
exists and the ready condition does not exist. If a start is commanded, then a No Line fault is declared.
If the Inline Configuration parameter is set to a time delay, then the MX
3
assumes that there is an Inline
contactor and that line voltage need not be present while stopped. If no line is detected, then the No Line
alarm condition does not exist and the ready condition does exist. If a start is commanded and there is no
detected line voltage for the time period defined by this parameter, then a “noL” (No Line) fault is declared.
In order to control an inline contactor, program a relay as a Run relay.
z
NOTE:
This fault is different than over/under voltage since it detects the presence of NO line.
See Also Relay Output Configuration parameters (I/O 10-15) on page 91.
Bypass Feedback Time I/O 25
LCD Display
Range
0.1 – 5.0 seconds
(Default: 2.0)
Description The starter contains a built in dedicated bypass feedback input that is enabled when the dedicated stack relay
is factory programmed to "bypass". The programmable inputs DI 1, DI 2, DI 3, DI4, DI5, DI6, DI7 or DI8
may also be used to monitor an auxiliary contact from the bypass contactor(s) or in the case of a wye-delta
starter the 2M contactor. The digital input is expected to be in the same state as the UTS relay. If it is not, the
MX
3
trips on Fault 48 (Bypass Fault).
The Bypass Confirmation input must be different from the UTS relay for the time period specified by this
parameter before a fault is declared. There is no alarm associated with this fault.

Keypad Stop Disable I/O 26
LCD Display
Range LCD Description
Disabled Keypad Stop does not stop the starter
Enabled Keypad Stop does stop the starter
(Default)
Description If “Disabled”
When this parameter is set to "Disabled", the keypad Stop button is de-activated. This should be done with
caution, as the [STOP] will not stop the starter.
