11.3 Setting of Switches
11.3.1 Setting of Burnout Switch
The burnout function sets the direction of current
output in situations during occurring the system
alarm. Upon shipment from the manufacturing
plant, the burnout direction is set to High (21.6 mA
or more); however, in cases where the optional
code C1 has been specified, the output direction
will be set to Low (3.2 mA or less).
Modification of the burnout direction must be carried
out using the setting switch from the amplifier’s
board (Switch 2) (See Figure 11.3.1).

NOTE
On the amplifier’s board, the burnout setting
switch (Switch 2) and the write protect switch
(Switch 1) are located adjacent to each other.
Accordingly, special care should be taken when
making switch settings.

11.3.2 Setting of Write Protect Switch
By setting the write protect function to “Protect” it is
possible to prevent the overwriting of parameters.
Write protection can be carried out using either the
hardware switch on the amplifier board (Switch 1) or
software parameter settings. If either of these items
is set to “Protect,” the overwriting of parameters will
be prohibited.
NOTE
If the hardware switch is set to “Protect,” it
will not be possible to overwrite parameters;
furthermore, this condition will be maintained
until the switch is set to “Enable.”
For more details regarding usage of the write
protect function and the software’s parameter
switches, refer to “Chapter 6: Parameter
Description.”
