VOLTAGE MONITORING
Figure 35
– Voltage Monitor Settings
Optimizer3 monitors Voltage with loop-powered 4-20 mA Voltage transducers. The transducers can be used to monitor DC station
battery voltage at the circuit breaker, AC station service voltage at the circuit breaker, or motor activity. When Voltage is selected,
scaling for the mA current range and voltage range appear.
High and Low Voltage Alarm Limits appear. If either Limit is set to 0 (zero), the alarm is disabled. The Low Voltage Alarm Limit
is asserted if the measured voltage is less than or equal to the setting. The High Voltage Alarm Limit is asserted if the measured
voltage is greater than or equal to the setting.
A hysteresis of 3 volts is applied to an active alarm to reduce nuisance toggling of the alarm. The alarm is non-latching and clears
itself when the measured voltage is between the alarm limits.
If Yes is selected for Run-Time Metrics, it is assumed the voltage sensor input is connected in parallel to a spring charging motor, air
compressor motor, or hydraulic pump motor. The cumulative run time, the number of runs per day, and average run duration are
reported and logged. If Yes is selected for Monitor Continuous Voltage, the daily average, minimum, maximum, and sample count
are reported and logged.
