- Programmable settings for either current or voltage input, threshold levels and over or under relay alarms.
- Internal DIP switches may be set for either 0 – 1mAdc or 0 – 10Vdc, and may be set for under alarm or over alarm relay operation.
- Lid mounted two digit numerical push-button switch calibrated as percent of full-scale with a threshold range of 01 – 99 percent.
- Red LED lamp lights to indicate when threshold level has been obtained.
- Highlighted area indicates Factory Setting. Unit is set at factory for the 0-1mA input and in the over range alarm mode.
- Under Range Alarm
The output relay will energize when instrument power is applied and the current is above the set point threshold. It will remain in a “Fail Safe” mode until either the input current drops below the set point threshold or instrument power is removed.
- Over Range Alarm
The output relay will energize when instrument power is applied and will remain in a “Fail Safe” mode until either the instrument power is removed or the input current exceeds the set point threshold level.
