4.2.1. UTILITY UNDER VOLTAGE SETPOINT
A potentiometer is provided to adjust the setpoint of the TSC 80’s utility under voltage
sensor. The under voltage setting is expressed in percentage of system voltage setting
with an adjustable range of 70-95% (e.g. If system voltage configuration jumper is set
for 600V, an 80% under voltage setting will correspond to an actual 540VAC setpoint.)
NOTE
The actual under voltage setpoint voltage is calculated based
on the TSC 80 voltage configuration jumper setting (i.e. nominal
system voltage) and the potentiometer setting. Actual system
operating voltage should not be used to calculate the under
voltage setpoint.
The under voltage setting is for a falling utility voltage (i.e. “drop-out” setting) on any
one phase. The under voltage sensor will reset to normal when the utility voltage rises
5% above the “drop-out setting (i.e. differential value). Example: if under voltage is
adjusted to an 80% drop-out value, it will reset at 85% voltage. The 5% differential
value is not programmable.
