Undervoltage Sensing Input Range
High Range:
0.5 to 12 Vac (sensing input range 1, 2, 5, or 6) or 1.0 to 24 Vac
(sensing input range 3, 4, 7, or 8).
Low Range:
0.1 to 2.5 Vac (sensing input range 1, 2, 5, or 6) or 0.2 to 5.0 Vac
(sensing input range 3, 4, 7, or 8).
Pickup Accuracy
1 to 24 Vac range:
±
2% or 20 millivolts
All other ranges:
±
2% or 10 millivolts
Overvoltage Sensing Input Range
Ranges selectable by unit type for 50 or 60 Hz operation: 1 to 20 Vac, 10 to 50 Vac, 2 to 40 Vac, 20 to
100 Vac.
Pickup Accuracy
120 Vac (sensing input range 1, 2, 5, or 6): ±2% or 100 millivolts, whichever is greater
240 Vac (sensing input range 3, 4, 7, or 8): ±2% or 200 millivolts, whichever is greater
Dropout
98% of pickup within 7 cycles.
Timing Characteristics
Instantaneous:
Less than 70 milliseconds (60-Hz relays) or less than 84 milliseconds
(50-Hz relays) for a voltage level that exceeds the pickup setting by
5% or 1 volt, whichever is greater
Definite:
Adjustable from 00.1 to 99.9 seconds, in steps of 0.1 seconds.
Accuracy is within 2% or 100 milliseconds, whichever is greater. (A
setting of 00.0 provides instantaneous timing.)
Inverse:
Response time decreases as the difference between the monitored
voltage and the setpoint increases. The inverse time characteristics
switch is adjustable from 01 to 99 in 01 increments. Each position
corresponds to a specific curve except 00, which is instantaneous.
Accuracy is within ±5% or 25 milliseconds (whichever is greater) of
the indicated time for any combination of the time dial and within
±
2% of the voltage magnitude or 100 millivolts (for the 120 Vac
sensing range) or 200 millivolts (for the 240 Vac sensing range)
(whichever is greater) from the actual pickup value. Inverse time is
repeatable within ±2% or 25 milliseconds (whichever is greater) for
any time dial or pickup setting. The characteristic curves are defined
in Figures 1-3 and 1-4.
