Relationship Between Alarm and Display/Output

The relationship between the state of comprehensive alarm (Warning, Critical), alarm bar, numeric LCD
display, and transistor output 1, 2 is shown below.
Described below is the case where the alarm latch is disabled and the case where it is enabled.
When the Alarm Latch is Disabled
If you set the alarm latch to "Disable (no latch)" using the software tool or message communications,
the alarm condition of the comprehensive alarm (warning or critical) will not be latched.
After the comprehensive alarm (Warning or Critical) occurs, if the measurement value falls below the
hysteresis (i.e., 10% of the threshold setting value) of the Warning or Critical threshold (for the upper
limit alarm) or higher (for the lower limit alarm), the state of the comprehensive alarm (alarm bar and
transistor outputs 1 and 2) is canceled.
 When the Trigger Mode Is "Free run (no trigger)"
When power is turned ON, measuring and monitoring are started.

*1. In the above figure, the power-ON state and the unmeasured state (i.e., the state
until the measurement value is calculated) that exist immediately after turning ON
the power as shown on page 3-7 are omitted.
*2. The transistor output method of output 1 and output 2 can also be set to "Normally
Open". In the case of Normally Open, ON/OFF is opposite to the above.
