AL1 and AL2 Contacts: 1 SPDT 2A max 0 240Vac resistive load.
AL3 Contacts: 1 SPST selectable NO/NC 2A max @ 240Vac resistive load.
Contact Protection: Varistor for spike protection.
Alarm Type: Each alarm is keyboard programmable for:
• Primary/Secondary input
• High/Low/Low inhibited on start up
• Auto/Manual reset
Excitation Type: Keyboard configurable for each alarm: relay coil energized in no alarm
condition (failsafe) or relay coil energized in alarm condition (non-failsafe).
Threshold: From 0 to 110% Full Scale (the threshold may be limited due to the selected
full scale value).
Hysteresis: Keyboard programmable for each alarm; from 0.1% to 10.0% of span or 1
LSD (whichever is greater) for each alarm.
