How to remove the safety option:
1.
Disconnect all power supplies before removing
the option.
2.
Verify that no voltage is present.
3.
Remove the safety option according to the
instructions in
Installation
in
VLT
®
AutomationDrive FC 301/FC 302 Operating
Instructions
.
NOTICE
If the removed safety option is installed in another
frequency converter, the frequency converter issues a
warning. The user can then select the safety configu-
ration from either the frequency converter or from the
safety option.
9.2.2 Replacing the Safety Option
WARNING
ELECTRICAL SHOCK HAZARD!
Always disconnect mains supply to the frequency
converter before removing the safety option.
When replacing the safety option, note the following:
•
If the firmware version has changed, configured
functions and stated parameters may no longer
be supported or may have been modified. Adapt
the configuration in the MCT 10 Set-up Software.
Use one of the following ways to program the safety
option after the replacement:
•
Reset the safety option to blank initial state as
described in
MCT 10 Set-up Software Operating
Instructions
and reprogram the safety option
using MCT 10 Set-up Software as on the first
commissioning as described in
and
•
Use parameter mismatch functionality to use an
existing parameter set with the new safety
option.
•
Copy the safe parameters using the graphical
LCP, see
chapter 9.2.4 Copying Safe Parameter
NOTICE
Protect the safety parameter configuration from changes
using the password protection. For example, the changes
may occur when there is a parameter mismatch (see
chapter 9.2.3 Mismatch of Safety Option Parameters
), or
when copying the parameters via LCP.
0-68 Safety
Parameters Password
and
0-69 Password Protection of
Safety Parameters
allow to configure the safety
parameter password protection. This protection is
different from the password that MCT 10 Set-up
Software uses, for more information, see
NOTICE
If the safety option is replaced with a different safety
option model, for example, if Safety Option MCB 152 is
replaced with Safety Option MCB 150 or vice versa, the
frequency converter trips with
Alarm 67, Option Change
or
Alarm 88, Option Detection
. For more information, see
chapter 9.2.1 Removing the Safety Option
.
9.2.3 Mismatch of Safety Option
Parameters
At each power-up, the parameter mismatch functionality
checks if the safety parameters in the frequency converter
and the safety option are different. If there is a difference,
for example after a replacement of the safety option, it is
possible to select 1 of the valid detected safety parameter
configurations using the
SO Param. Selection
form on the
LCP:
130BD115.10
SO Param. Selection
Mismatch of SO param.set
detected. Please choose:
!1(1)
0 RPM 0.00 A
SO : Test1234_ 1.00
VLT : SafeSet1_ 1.00
Illustration 9.1 SO Param. Selection Form.
After selecting 1 of the parameter sets, the set is written to
the safety option. During this process the safety option
saves a checksum along with the parameter set, which
allows to identify the duplicated safety option parameters.
The LCP messages guide through the parameter transfer.
Follow the steps below when replacing the safety option,
assuming that the safety parameters in the frequency
converter have the correct values:
1.
Select
VLT
.
2.
If configured, enter the password for the safety
option configuration that is being copied. See the
Maintenance, Diagnostics an...
