[EV1/EV2 Energized/De-energized]
When
(Energized) is selected, Event output 1 or 2 is conductive (ON) while the EV1/EV2
indicator is lit.
Event output 1 or 2 is not conductive (OFF) while the EV1/EV2 indicator is not lit.
When
(De-energized) is selected, Event output 1 or 2 is not conductive (OFF) while the
EV1/EV2 indicator is lit.
Event output 1 or 2 is conductive (ON) while the EV1/EV2 indicator is not lit.

EV1 value and EV1 hysteresis represent EV1 alarm value and EV1 alarm hysteresis respectively.
For EV2, substitute EV1 with EV2.
[Loop Break Alarm]
When the control action is Reverse (Heating) control:
If the PV does not
reach
the Loop break alarm span setting within the time allotted to assess the Loop
break alarm (after the MV has reached 100% or the OUT high limit value), the alarm will be activated.
Likewise, if the PV does not
drop to
the Loop break alarm span setting within the time allotted to
assess the Loop break alarm (after the MV has reached 0% or the OUT low limit value), the alarm will
be activated.
When the control action is Direct (Cooling) control:
If the PV does not
drop to
the Loop break alarm span setting within the time allotted to assess the Loop
break alarm (after the MV has reached 100% or the OUT high limit value), the alarm will be activated.
Likewise, if the PV does not
reach
the Loop break alarm span setting within the time allotted to assess
the Loop break alarm (after the MV has reached 0% or the OUT low limit value), the alarm will be
activated.
If Serial communication is specified, status can be read by reading Status flag 1.
Serial communication can be specified only for the KT4R model.
