IM 11M13A01-02E 10-10
In the Blowback setup display shown in Figure 10.10, if you choose “Mode: No
function” or “Semi-auto blowback,” the Interval, Start Date, and Start Time for these are
not displayed.
CAUTION
• If the blowback is executed with an input contact, it must be preset in the Input
contacts setting (for more details, see Section 8.5, earlier in this manual).
• In Section 8.4, “Output Contact Setup,” earlier in this manual, set the contact used as
the blowback switch beforehand.
• Do not set any other function for the contact used as the blowback switch. Otherwise,
blowback may be activated when the contact is closed by any other function.
• No blowback is executed during calibration or maintenance service. If automatic
blowback reaches the preset start time during calibration or maintenance service,
blowback will be executed after completing the calibration or maintenance service and
after the equipment returns to the measurement mode.
• If automatic blowback reaches the preset start time during semi-automatic blowback,
the current automatic blowback will not be executed.
• If you set the blowback interval at 000 days, 00 hours, only the first blowback is then
executed. No subsequent blowbacks will be executed.
• If a past date is set for the Start time, no blowback will be executed.
