1-3. Cautions on Operation

•
When there is a malfunction, related characters as shown
in "8. ALARM DISPLAY/OUTPUT" are displayed instead
of numbers. Refer to that section for information.
•
When you make an error in operation, or when an alarm
message is displayed, retry the operation.
•
Be sure to operate each key and external input signal
(contact point) correctly in accordance with the operating
procedures. Otherwise, an operational error may occur.
•
Be sure to perform operations and connections such as
that of each I/O (BCD) in accordance with explanations
given in each section. Unless you operate the unit correctly,
operational error or unit malfunction may occur.
Notes on storing the initial setting data
Data input by the initial settings is written to a flash memory.
The display goes blank and the REF and PEAK lamps flash
while the memory is being written. Absolutely do not turn off
the power while the memory is being written. (If the power is
turned off, the memory cannot be written and the settings
must be made again.) The memory is written in the following
three cases.
a. When the power is turned on.
b. When the menu settings are ended.
c. When RESET key is pressed to end the initial settings
and start the count display.
