36 Chapter 4 Operator Control And Display Panel

Alarm message		Description
REC FLASH UPDATE	Ongoing update of rectifier firmware
INV FLASH UPDATE	Ongoing update of inverter firmware
MONITOR FLASH		Ongoing update of monitor firmware
UPDATE
Unit off confirm		Prompt to press the Enter key (F4) to acknowledge that the UPS will be disconnected from other
		paralleled UPS modules
System off confirm		Prompt to press the Enter key (F4) to acknowledge that the all paralleled UPS will be disconnected
		from the load
Fault reset		FAULT CLEAR direct access key pressed
Alarm silence		SILENCE ON/OFF direct access key pressed
Turn on fail		Inverter failed to turn on when INVERTER ON direct access key was pressed. This may be as a
		result of Invalid Operation (Maintenance bypass on) or DC bus or rectifier not ready
Alarm reset		FAULT CLEAR or SILENCE ON/OFF direct access key pressed
Transfer confirm		Prompt to press the Enter key (F4) to acknowledge that an interrupted load transfer to bypass will
		happen
Transfer cancel	Prompt to press the ESC key (F4) to avoid that an interrupted load transfer to bypass will happen
Manual turn on		Manual Turn On through operator control and display panel
Manual turn off		Manual Turn Off through operator control and display panel
Battery ground fault		Battery leakage to ground detected (option)
Protocol version clash	Firmware incompatibility between Monitor Board and Digital Signal Processor Board
Setting save error		History records not saved. (Reserved)
Battery overtemp.	The Battery temperature is over limit. Check the battery temperature and ventilation
Ambient overtemp.	The Ambient temperature is over limit. Check the ventilation of UPS room
Battery fault		Battery detected faulty (Reserved)
Battery maintained		Battery test failed, Battery should be replaced
		Before the end of discharge, battery undervoltage pre-warning should occur. After this pre-warning,
Battery low pre-warning		battery should have the capacity for 3 minutes discharging with full load. The time is user-configured
		from 3 to 60 minutes. Shut down the load in time
Battery end of discharge		Inverter turned off due to low battery voltage. Check the utility failure and try to recover it
Inverter comm. fail		Internal RS485 communication failure between monitor and inverter
		The CAN communication between different UPSs within a parallel system fails. 1.Check if there are
Parallel comm. fail		some UPSs not powered on in the parallel system. If so, power on these UPSs and check if the
		alarm disappears. 2. Press the FAULT CLEAR push button
		This alarm is triggered by an inverter software routine when the amplitude or frequency of bypass
		voltage is beyond the normal range. The amplitude threshold is fixed for positive and negative 10%
		rating.
		This alarm automatically resets once the bypass voltage goes normal. 1. First verify that the bypass
Bypass unable to trace		voltage and frequency displayed on the operator control and display panel is within the selected
		range. Note here the rated voltage and frequency are specified by the system voltage level and
		output frequency level respectively. 2. If the displayed voltage is believed to be abnormal, then verify
		the bypass voltage and frequency presented to the UPS. Check the external supply if it is found to
		be faulty
		This alarm is triggered by an inverter software routine when the amplitude or frequency of bypass
		voltage exceeds the limit. This alarm automatically resets once the bypass voltage goes normal.
		First check if there are some relevant alarms such as Bypass disconnect open, Bypass phase
		reverse. If they appear, solve them first. 1. Then verify that the bypass voltage and frequency
Bypass abnormal		displayed on the operator control and display panel is within the bypass limit. Note here the rated
		voltage and frequency are specified by the system voltage level and output frequency level
		respectively. 2. If the displayed voltage is believed to be abnormal, then verify the bypass voltage
		and frequency presented to the UPS. Check the external bypass supply if it is found to be faulty. If
		the utility is likely to trigger this alarm frequently, the bypass limit can be changed a little larger
		through the configuration software according to the customer’s agreement
		This alarm is triggered by an inverter software routine when the inverter and bypass waveforms are
		misaligned by more than 6 degrees in phase. This alarm resets automatically once the condition is
Inverter asynchronous		no longer true. 1. First check if the alarm Bypass unable to trace or Bypass abnormal occurs. If so,
		solve it first.
		2. Verify the waveform of the bypass voltage. If it is too distorted, ask the customer to verify and seek
		any possible measurements
Inverter output abnormal		Inverter output voltage beyond limits. Load transfers to bypass
