Alarms
The CPC incorporates a LOW and HIGH Alarm with an adjustable hysteresis setting. The low and High alarm levels
are activated within the range:
Example: 10% low alarm = 4 + (10% x 16) = 5.6 mA. 90% High alarm = 4 + (90% x 16) = 18.4 mA.
Hysteresis:
1. The calculation is: 4 + (2% x 16) = 0.32 mA.
Low alarm hysteresis in this example = 5.6 mA + 0.32 mA = 5.92 mA.
High alarm hysteresis in this example = 18.4 mA - 0.32 mA = 18.08 mA.
2. Enter the requested percentage, for the alarms and hysteresis.
3. Click on "Test" to close or open your contact relay.
4. Click on "Write Alarms" (1) once your alarm settings are correct.
