1. Introduction
In the case of the SC series, a backup battery is used for keeping the system
parameters when the power is off. If the system parameters cannot be kept in
memory because of the battery degradation, the system of SC controller must reset
at the start-up for using the controller normally.
It is necessary to reset the system by the front panel or by using a
remote command from the out side client.
SC-200、SC-210、SC-400、SC-410、SC-800
It is necessary to reset the system by RC-10 not included in the price
or by using a remote command from the out side client.
SC-020、SC-021
The information backuped on ROM in the controller is erased, thus it
cannot be operated normarly. In the case, it is necessary to reset the
system every start-up. It is available to set new parameters by user,
but the new parameter have never kept after then the power off.
If the backup battery is discharged, ...

Backup system parameters | Kohzu Precision Co., Ltd.
3. Backup system parameters
When replacing a backup battery, the system parameters of the SC controller3 are deleted,
since the backup battery is removed temporarily. Therefore, backup of the system
parameters are necessary before starting the tasks. Backup can be performed with one
method to use a Windows application and the other method to take notes from the front
panel.
3.1. Backup with Chamonix
Using "Chamonix", the standard control application made by our company, backup of a SC
controller is possible. For details, refer to "Backup method of system parameters".
Figure 3 Chamonix
3.2. Take notes from the front panel
It is possible to take notes of the system parameter values displayed in the front panel of a
SC controller. For operation on the front panel of a SC controller, refer to the instruction
manual for the SC controller.
3
System parameters saved in a SC controller may be referred to as system settings on
control software of our company and old version of documents for SC controllers, etc.
When referring to these documents, please regard system parameters in this manual as
system settings.
For backup method using
Chamonix, refer to "Backup
method of system parameters".

5.1. Connect the cable
After connecting the power cable to the SC controller, turn the power of the SC ON. As
shown in Figure 15, "**RAM Data Error**" is displayed.
Figure 15 Display immediately after turning the power ON
5.2. Reset the system parameters
Push the "F5" button on the front panel as shown in Figure 16. The system of the SC
controller is reset. When RAM with saved system parameters is not correctly operated due
to low battery, system parameters may not be correct. To assure correct operation, it is
required to reset the system.

Kohzu Precision Co., Ltd. | Reset system parameters with Chamonix
15
SC-020 and SC-021do not have a front panel. Therefore, reset should be performed by
sending RST command with control software like Chamonix or by setting SYS No.36 of the
system parameters to 1 with the optional product, RC-10 (production has finished).
5.3. Reset system parameters with Chamonix
The reset method of system parameters using Chamonix is described.
Figure 17 Command button
As shown in Figure 17, push the Command button at the top part of the main form.
"Chamonix Command Control" opens. As shown in Figure 18, enter "RST" in the sending
box at the bottom part, and push the "Enter" key to send the RST command to the SC
controller. As shown in the figure, the reply from the SC controller is displayed as "→C
RST" that indicates the system parameters are successfully reset.

5.4. Restore system parameters
System parameters before replacing a battery are changed to default system parameters.
Finally, restore the system parameters using the system parameters backed-up before
replacing a battery in Backup system parameters3. Backup can be restored with one
method to use a Windows application and the other method to directly enter on the front
panel.
5.5. Restore of backup with Chamonix
Using "Chamonix", the standard control application made by our company, the backup of a
SC controller can be restored. When using "Chamonix" available with a fee, the backup can
be restored with the same method. For details, refer to "Backup method of system
parameters".
Figure 19 Restore with Chamonix
5.6. Restore backup from the front panel
When the system parameters before replacing a battery are taken to notes, the parameters
can be entered on the front panel of the SC controller. For operation on the front panel of a
SC controller, refer to the instruction manual of each SC controller.
For the restoring method of
system parameters using
Chamonix, refer to "Backup
method of system parameters".
