Step : Reapply Power To The Unit; Step 4: Verify That The Signals And Status Are Correct; Step 5: Adjust The New Drive's Programming - ABB ACH400 Series Retrofit Manual

Step 23: Reapply power to the unit.
 First, remove the safety tagout/lockout from the feeder device. Be certain to follow all designated
safety procedures.
 Close the branch device.
 Now turn the disconnect handle on the bypass unit to the "On" position.
Step 24: Verify that the signals and status are correct.
 Verify that the unit is powered. The Control Panel on the drive
should be illuminated and status lights should appear on the by-
pass unit.
Verify that the Control Panel green led is flashing and that the wel-

come screen is displayed on the unit. The welcome screen may be
alternating with an Alarm 2021 (no enable) screen. This disabled
condition will remain until programming selects the proper Macro
for the drive.
 Verify that the bypass unit has a steady, illuminated, green
"Ready" led.
 Verify that the bypass unit has a steady, illuminated, green "En-
able" led. If this led is not illuminated, manually supply the enable
signal from the system. This most likely requires reversal of one or
more of the actions taken in Step 3.
Step 25: Adjust the new drive's programming.
 Press the "OK" button on the Control Panel to access the Start-Up Assistant. Press "Save" to ac-
cept "English" as the language. Select "Commission" and then press "Save".
 Enter the correct motor data as recorded in the ACH400 parameters from Step 2. These include
Motor Volts, Motor Amps, Motor Frequency, Motor RPM and Motor Power.
Select "E-BYPASS" as the macro and press "Save".

 Complete the rest of the remaining steps in the Start-Up Assistant, answering questions and select-
ing features based on your systems design.
