5.0 Operation
5.7 Extended capabilities - continued
output voltage may be set to a nominal 220, 225, 230 or 240 Vac. The UPS’s default setting
is 225 Vac.
● Utility failure sensitivity - The UPS’s sensitivity to line voltage distortions may be
customized to allow use of the UPS in “noisy” electrical environments or with fuel
powered generators. High, medium and low sensitivity settings may be chosen. The high
setting provides the best protection from all utility voltage vagaries. The medium setting
is selected where rapid low amplitude line voltage fluctuations occur frequently as the
result of motor load switching in air conditioners, elevators, etc. The low setting is
selected when the UPS is operated from an inexpensive fuel powered generator. The
UPS’s utility failure sensitivity default setting is high.
● Audible alarm operation - The UPS’s audible alarm beeps four times every 30 seconds
in response to failed utility conditions. The alarm beeps continuously when low battery
conditions are reached. This is the default operation. Audible alarm operation may be
customized such that an indication in response to utility failure is delayed by 30 seconds,
silenced until low battery conditions are reached, or muted during both utility failure and
low battery conditions.
● Minimum battery capacity to restart - The UPS may be customized so that it will not
restart upon restoration of the utility until the battery has been recharged to within 0%,
10%, 25% or 90% of full capacity. This function eliminates unexpectedly short run times
when repetitive utility failures occur. The UPS’s minimum battery capacity to restart
default setting is 0%.
● Shut down, turn off delay - The UPS’s shut down or turn off delay interval may be
customized to 20, 180, 300 or 600 seconds. The UPS’s shut down delay default setting is
20 seconds. Extension of the shut delay is useful where the time between issuance of the
UPS shut down command, and actual completion of the operating system shutdown
routine is longer than 20 seconds.
● Turn on delay - The UPS’s turn on delay may be customized to 0, 60, 180 or 300 seconds.
The UPS’s turn on delay default setting is 0 seconds.
