Qualify Bypass

[Always] [Never] [Bypass Disabled]

Always

 

If Always, Bypass operation is allowed when:

 

 

S

Bypass voltages > the value set for Bypass

 

 

 

Voltage Low Limit

 

 

S

Bypass voltages < the value set for Bypass

 

 

 

Voltage High Limit

 

 

S

Bypass frequency > (nominal frequency -3 Hz)

 

 

S

Bypass frequency < (nominal frequency +3 Hz)

 

 

S

Inverter is synchronized with Bypass when

 

 

 

unsynchronized transfers are disabled by the

 

 

 

value set for Unsynchronized Transfers

 

 

If Never, Bypass operation is always allowed; voltage

 

 

and frequency limits are not in use.

 

 

If Bypass Disabled, Bypass operation is prohibited.

 

 

 

 

Synchronization Window

[Sync Disabled] [±0.5 Hz] [±1.0 Hz] [±1.5 Hz]

±3.0 Hz

 

[±2.0 Hz] [±2.5 Hz] [±3.0 Hz]

 

 

If ±3.0 Hz, on inverter operation the inverter tries to

 

 

synchronize with the Bypass when the Bypass

 

 

frequency is not more than 3 Hz from the nominal

 

 

output frequency; otherwise, the inverter goes to

 

 

nominal frequency. On Bypass mode, the sync

 

 

window is always ±3 Hz.

 

 

NOTE: In Sync Disabled state, if the Bypass

 

 

operation is allowed, the UPS synchronizes only

 

 

when it is operating on Bypass mode.

 

 

 

 

Unsynchronized Transfers

[Enabled] [Disabled]

Enabled

 

If Enabled, unsynchronized transfers to the Bypass

 

 

are allowed.

 

 

If Disabled, unsynchronized transfers to the Bypass

 

 

are not allowed.

 

 

NOTE: The Qualify Bypass setting may overrule the

 

 

Unsynchronized Transfers setting.
