5. 12. 15. 1 Overvoltage Reset Threshold
To determine the threshold level to reset the
overvoltage, find the voltage when an overvoltage alarm
will occur. This is the nominal AC line voltage (see
Section 5.5) multiplied by the overvoltage detection level
(see Section 5. 1 2. 1 2). Figure 5 . 1 illustrates the
overvoltage set and reset levels.
The reset voltage is a percentage of the difference (0 to
1 00%) between the nominal voltage and the overvoltage
detection level, as determined by the reset threshold.
You can calculate this by:
where
30
OVR = OVDL - RST x (OVDL - NOM)
OVR = Overvoltage Reset (Volts)
RST
=
Reset Threshold
OVDL = Overvoltage Detection Level (Volts)
NOM = Nominal AC line Voltage (Volts)
