Description
P00 Mains Normal Delay (0-3600)s
10
Time duration for Mains voltage from
abnormal to normal or from normal to
abnormal is used for ATS to switch.
P01

P02
Mians Under Volt
Value
(30-360)V
184
If the voltage sample is lower than it, under
voltage of Mains is considered; When it is
set 30V, under voltage signal shall not be
detected.
P03
Mains
Over
Volt
Value
(30-360)V
276
If the voltage sample is higher than it, over
voltage of Mains is considered; When it is
set 360V, overvoltage signal shall not be
detected.
P04 Transfer Delay
(0-99.9)s
1.0
It is the time interval for transferring switch
from mains open to generator close or from
generator open to mains close.

P06 Start Delay
(0-3600)s
1
Time duration from remote start signal is
active to engine startup.
