F9 DC BUS ????
Before PFC start, DC bus voltage is lower than 50 volts DC. PFC stage is no allowed to start.
F10 BOOSTER SOFT
Booster soft start step could not be completed within 16 seconds
F11 DC BUS ERROR
DC bus voltage is lower than PFC start minimum limit. PFC system can not start.
F12 SHORT CIRC.
There is a short circuit at the output of the UPS. Disconnect loads one by one and try to reset UPS.
F13 WAVEFORM
A63 INV.FAILURE alarm occurred 4 times within 60 minutes. Unstable waveform error.
F14 BATT.SAMPLE?
Battery voltage control signal is lost or signal level is wrong.
F15 4-INV FAIL
Inverter output low or high alarm has occurred 4 times within 1 hour. Inverter output voltage is out of tolerance.
F16 4-OVERCURR.
Overcurrent has been sensed in UPS 4 times within 1 hour.
F17 MIS-FUNCTION
Maintenance bypass switch is suddenly turned on without switching to manual bypass first.
F18 ALT.PROTECT.

ADJUST MENU
Adjust menu contains some factory selectable options, settings and adjustments. A service password is
required,to access the ADJUST MENU.please refer to your local distributor for changing your options.
NOTE : adjust menu is only for service purpose. the wrong usage of this menu can cause damage to UPS.
The following options are selectable from adjust menu :
SPLIT BYP:ON /OFF (Split bypass : on/off)
OPTION DESCRIPTION
ON Bypass voltage measurement enabled in measures menu. (BYP.: 230V 50.0Hz)
OFF Bypass voltage measurement disabled in measures menu.
Split bypass input is the secondary AC input to the UPS. This input is used for transferring the load to bypass.
As a default, there is no split bypass input on a standard CL115D series UPS. But during production in the
factory, it is possible to install a separate split bypass input to the UPS. The voltage and frequency
measurement system is ready and the measurement inputs are shorted to the already available AC input of the
UPS. If OFF option is selected bypass voltage and frequency measurement menu item will be cleared from
measures menu. If ON option is selected, separate bypass measurements will be shown in measures menu.
REPO INPUT:NO/NC contact (function of the Remote emergency power off input)
OPTION DESCRIPTION
NO If REPO input terminals are shorted UPS applies emergency stop
NC If REPO input terminals are opened UPS applies emergency stop
This selection will be applied after the next power on.
