Parameter Values
40 Slow Detect Hi Lmt
Decreasing this makes the UPS
more sensitive to an overvoltage
condition by lowering the overvoltage
detection level.
NOTE: The Slow Detect Hi Hyst
parameter (42) should be adjusted
by the same % of rated line input
voltage
42 Slow Detect High Hyst
Increasing this raises the voltage
level where the UPS resumes On
Line mode after a overvoltage has
been corrected.
44 Slow Detect Boost High
Increasing this raises the return
voltage level from Boost mode to On
Line mode.
45 Slow Detect Boost Low
Increasing this raises the voltage
level where the UPS goes to Boost
mode.
43 Slow Detect Low Hyst
Decreasing this lowers the voltage
level where the UPS resumes On
Line mode after an low line condition
has been corrected.
41 Slow Detect Low Lmt
Increasing this makes the UPS more
sensitive to a low line disturbance
(brownout) by raising the brownout
detection level.
NOTE: The Slow Detect Low Hyst
(43) should be adjusted by the same
% of rated line input voltage.
