Description
35
N# INV Ov Load Tout
N# Power Module Inverter Over Load Timeout. The UPS overload status continues
and the overload times out.
Note:
The highest loaded phase will indicate overload timing-out first.
When the timer is active, then the alarm “unit over load” should also be active as the
load is above nominal.
When the time has expired, the inverter Switch is opened and the load transferred to
bypass.
If the load decreases to lower than 95%, after 2 minutes, the system will transfer
back to inverter mode. Check the load (%) displayed in LCD so as to confirm if this
alarm is true. If LCD displays that overload happens, then check the actual load and
confirm if the UPS has over load before alarm happens.
36
N# INV Ov Temp.
The N# Power Module Inverter Over Temperature.
The temperature of the inverter heat sink is too high to keep inverter running. This
alarm is triggered by the signal from the temperature monitoring device mounted in
the inverter IGBTs. The UPS recovers automatically after the over temperature signal
disappears.
If over temperature exists, check:
Whether the ambient temperature is too high.
Whether the ventilation channel is blocked.
Whether fan fault happens.
Whether inverter overload time is out.
37
On Ups Inhibited
Inhibit system transfer from bypass to UPS (inverter). Check:
Whether the power module’s capacity is big enough for load.
Whether the rectifier is ready.
Whether the bypass voltage is normal.
38
Manual Transfer Byp
Transfer to bypass manually
39
Esc Manual Byp
Escape from “transfer to bypass manually” command. If UPS has been transferred to
bypass manually, this command enable UPS to transfer to inverter.
40
Batt Volt Low
Battery Voltage is Low. Before the end of discharging, battery voltage is low warning
should occur. After this pre-warning, battery should have the capacity for 3 minutes
discharging with full load.
41
Batt Reverse
Battery cables are connected not correctly.
42
N# INV Protect
The N# Power Module Inverter Protect. Check:
Whether inverter voltage is abnormal
Whether inverter voltage is much different from other modules, if yes, please adjust
inverter voltage of the power module separately.
43
Ip Neutral Lost
The mains neutral wire is lost or not detected. For 3 phases UPS, it’s recommended
that user use a 3-poles breaker or switch between input power and UPS.
44
Byp Fan Fail
At least one of bypass module Fans Fails
45
N# Manual Shutdown
The N# Power Module is manually shutdown. The power module shuts down
rectifier and inverter, and there’s on inverter output.
46
ManBoost
Manually force the Charger work in boost charge mode.
47
Manfloat
Manually force the charger work in float charge mode.
48
Arrears Shutdown
Reserved.
49
Lost N+X Redundant
Lost N+X Redundant. There is no X redundant powers module in system.
50
EOD Sys Inhibited
System is inhibited to supply after the battery is EOD (end of discharging)
