SP3.12  Overvoltage Trip Level: Typically used to indicate 

that the line voltage is too high and at which point a 

trip occurs

•  Overvoltage Trip Delay: The amount of time that 

the overvoltage condition must exist before a trip 

will occur.

SP3.13  Undervoltage Alarm Level: Typically used to 

indicate when the line voltage is too low. This is an 

alarm level. 

•  Undervoltage Alarm Delay: The amount of time 

that the overvoltage condition must exist before a 

trip will occur.

SP3.14  Undervoltage Trip Level: Typically used to 

indicate that the line voltage is too low and at which 

point a trip occurs

•  Undervoltage Trip Delay: The amount of time that 

the undervoltage condition must exist before a trip 

will occur.

SP3.15  Line Frequency Trip Window: The acceptable 

amount of drift above or below the line frequency 

(Hz) before a trip is generated.

•  Line Frequency Trip Delay: The amount of time 

that the frequency drift condition must exist beyond 

the window before a trip will occur.

SP3.16  Power Factor Lead Alarm: Typically used to 

indicate a leading power factor. 

•  Power Factor Lead Alarm Delay: The amount of 

time that the power factor lead condition must exist 

beyond the window before a trip will occur.

SP3.17  Power Factor Lead Trip: The acceptable amount 

of power factor lead before a trip is generated.

•  Power Factor Lead Delay: The amount of time 

that the power factor lead condition must exist 

beyond the window before a trip will occur.

SP3.18  Power Factor Lag Alarm: Typically used to 

indicate a lagging power factor. 

•  Power Factor Lag Alarm Delay: The amount of 

time that the power factor lagging condition must 

exist beyond the window before a trip will occur.

SP3.19  Power Factor Lag Trip: The acceptable amount 

of power factor lag before a trip is generated.

•  Power Factor Lag Delay: The amount of time 

that the power factor lag condition must exist 

beyond the window before a trip will occur.

SP3.20  Power Demand Period: The soft starter 

measures the demand of the motor for several 

parameters (current, kW, kvar, kVA). The demand 

values of motors assists in energy management 

programs where processes may be altered or 

scheduled to reduce overall demand. Demand 

is calculated by a programmed amount of time 

where current, kW, kvar and kva samples are 

taken and then averaged and stored to assess 

demand.
