Reflash
Turns On/Off the reflash alarm operation of alarm output relays I01, I02, and I03.
When set to On, alarm output relays I01, I02, and I03 set to reflash alarm operation, and
the operation is fixed to OR, de-energized, and non-hold.
AND
Sets the AND/OR operation of alarm output relays.
None: No relays are set to AND operation. All relays are set to OR operation.
I01: Only I01 is set to AND operation.
I01-I02: I01 and I02 are set to AND operation.
I01-I03: I01 to I03 are set to AND operation.
I01-I04: I01 to I04 are set to AND operation.
I01-I05: I01 to I05 are set to AND operation.
I01-I06: I01 to I06 are set to AND operation.
Act
Sets whether the output relay is energized or de-energized when an alarm occurs.
Energize:
Energizes the relay when an alarm occurs. The relay is de-energized
during normal operation.
De_energize: De-energizes the relay when an alarm occurs. The relay is energized
during normal operation.
Behavior
Specifies whether to set the alarm output relay to hold operation or non-hold operation.
Nonhold:
Releases the relay output at the same time the alarm is released.
Hold:
Holds the relay output until the alarm ACK operation is executed.
Indicator
Specifies whether to set the alarm indication to hold operation or non-hold operation.
Nonhold:
Releases the alarm indication at the same time the alarm is released.
Hold:
Holds the alarm indication until the alarm ACK operation is executed.
Increase
Set the interval of the high limit on rate-of-change alarm to an integer between 1 and 15.
The interval is set to scan interval × (1 to 15).
Pen model:
The scan interval is 125 ms. The maximum interval is 1.875 s.
Dot model:
The maximum interval when the scan interval set to 1 s is 15 s. The
maximum interval when the scan interval set to 2.5 s is 37.5 s.
Decrease
Set the interval of the low limit on rate-of-change alarm to an integer between 1 and 15.
The setup procedure is the same as Increase.
Hysteresis
Sets the alarm hysteresis of the measurement channels.
The hysteresis width can be set in the range of 0.0% (Off) to 1.0% of the recording span
in 0.1 steps.
The hysteresis applies to all high limit and low limit alarms of measurement channels.
M_Hysteresis (Models with the Computation Function (/M1 Option))
Sets the alarm hysteresis of the computation channels.
The hysteresis width can be set in the range of 0.0% (Off) to 1.0% of the recording span
in 0.1 steps.
The hysteresis applies to all high limit and low limit alarms of computation channels.
