8. CONFIGURATION OF OTHER
OPERATING MODES.
8.1. BYPASS.
Fig. 38. Control keys.
"ESC"→ Exits the main menu.
" → Previous control screen.
"
" → Next control screen.
"
"ENTER" → Executes a control command.
When the "Go to bypass" command is executed, confirma-
tion is requested and the display immediately shows the
i
message "
Done". Similarly, when the "Switch to normal mode"
command is executed, the display immediately shows the message
i
"
Done".
Messages will be displayed for 5 seconds and will then change
to the new available control option. So, if the UPS was in Normal
mode and the user selected "Switch to Bypass", the new option
available would be "Switch to Normal mode", and if the UPS was
in Bypass mode and the user selected "Switch to Normal mode",
the new option available would be "Switch to Bypass".
If the UPS is not in Normal or Bypass mode, this option is not active
and is not displayed as a control option.
Since it is only a manual request from the LCD display, the LCD
display settings and Bypass limits must be overridden and send
the UPS to "Static bypass". The alarm history log should indicate
"Static bypass".
If the UPS works in "Static bypass" and the bypass frequency is out
of range, the UPS will switch to Standby mode.
