10.6 Replacing the Option Board
W A R N I N G
SHOCK HAZARD FROM CONTROL TERMINALS
The control terminals can have a dangerous voltage also when the drive is disconnected from mains. A contact with this voltage
can lead to injury.
Make sure that there is no voltage in the control terminals before touching the control terminals.
C A U T I O N
DAMAGE TO OPTION BOARDS
Do not install, remove, or replace option boards on the drive when the power is on. Doing this can cause damage to the boards.
Switch off the AC drive before installing, removing, or replacing option boards on the drive.
C A U T I O N
FAULTY OPTION BOARD
Indications of a faulty option board can be, for example, constant faults that indicate internal faults of the option board. Even if
the option board works correctly some of the time, there can be underlying faults that can create unexpected situations and
cause damage to the equipment.
Replace an option board when it is suspected to be faulty.
C A U T I O N
REPAIRING THE OPTION BOARD
Unsuccessful repair work can cause damage to the equipment. Return faulty option boards to the manufacturer for analysis.
Do not perform any repair work on the option board.
Find out if your software and parameter file version are supported by the new hardware version.
Parameterize the new option board. It can be necessary to load the existing parameter file from the current option board.
Changing the option board can affect the operation of whole safety system. It can be necessary to revalidate the safety system.
Changes may be due to different hardware versions or faults in either the old or new option board.
Procedure
Store the parameter file of the option board, for example, on the control board of the AC drive or on your PC.
If the old option board is intended to be used in another system or as a back-up, you can delete its parameter file using
factory reset. See 10.4 Factory Reset.
Disconnect power, including the power stage supply voltage and the controller supply.
Make sure that there is no voltage.
Remove the old option board.
Install the new option board using the instructions in 4.1 Installation Safety and 4.2 Installing the Option Board.
Commission the new option board.
Keep the replaced option board for further use, or contact Danfoss for possible analysis of the option board. Also see 10.8
Disposal.
After replacing the option board, the next start-up is the first start-up of the new option board. Do the checks and
procedures of the first start-up. See 9.1.2 Procedures Before the First Start-up of the System with the Option and
9.1.3 Preparing for Commissioning Checklist.
10.7 Replacement of Other Components of the Safety System
When you plan and make changes to other components of the safety system where the Advanced safety option board is included,
consider the possible effects of the changes.
