NOTE
To override momentary under voltage fluctuations, the TSC
80’s Engine Start Delay Timer feature is utilized.
Refer to Table 1 for the factory default settings of the utility under voltage sensor.
4.2.2. GENERATOR UNDERVOLTAGE SETPOINT
A potentiometer is provided to adjust the setpoint of the TSC 80’s generator 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 generator voltage (i.e. “drop-out” setting) on
any one phase. The under voltage sensor will reset to normal when the generator
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.
NOTE
To override momentary under voltage fluctuations, the under
voltage sensor is provided with a transient time delay period of
3 seconds which is non-adjustable.
Refer to Table 1 for the factory default settings of the generator under voltage sensor.
4.2.3. GENERATOR UNDER FREQUENCY SETPOINT
A potentiometer is provided to adjust the setpoint of the TSC 80’s generator under
frequency sensor. The under frequency setting is expressed in percentage of system
