Relay (for models with the optional alarm output terminal)
• It is possible to set relays even without an alarm output terminal (but there is no effect).
• The alarm output terminal number can be set from 0 to 12. However, there is no alarm output
when 0 is set.
■
AND/OR (output mode)
AND Alarms are assigned with the AND condition for activation of an alarm output terminal.
The relay turns ON when all alarms set for one alarm output terminal are activated.
OR
Alarms are assigned with the OR condition for activation of an alarm output terminal.
The relay turns ON when any of the alarms set for one alarm output terminal is
activated.
• If both AND and OR are set for the same alarm output terminal, the relay turns ON when all the
alarms set for AND are activated, or when one of the alarms set for OR is activated.
■
Marker*
• It is possible to set a marker No. that automatically writes an annotation on the trend screen when
an alarm occurs.
• If the setting is “0,” the marker function does not operate.
