U/V Auto Restart
Disable
Enables / Disables the auto Restart features.
• Set to “Disable”, if Restart is not required.
• Set to “Measured Voltage”, if control power supply (19-20) is stable during mains
failure (powered from UPS or DC). Mains Failure is detected and causes motor
stop, when voltage decreases below 65% of rated voltage. Mains restoration is
detected when voltage increases to above 85% of rated voltage.
• Set to “Both Sup & Vin” for normal AC mains (both measured voltage (35,37) and
control power supply (19,20) turn off during mains failure).
Note: Setting as “Auxiliary Supply” may not cause restart, for mains failure duration of less
than 0.5sec.
Restart occurs only if:
• Motor was Starting/Running before mains failure
• Turn off time is 0.1 - 4 sec. (±25%)
Range: Disable, Auxiliary Supply,
Measured Voltage, Both Sup. & Vin
U/V Restart Delay
4 Sec.
Time delay for the auto Restart feature, counted from mains (auxiliary supply or
measured voltage, as set on u/v Start Prevent) restoration
Range: 0.4 – 25 Sec.
O/V Level 1
115% of Vn
Over Voltage Level 1. Fault occurs when voltage is above set value for more than 1
second (fixed delay). Range: 100 - 120 % of Un. Increments of : 1%
O/V Level 2
120% of Vn
Over Voltage Level 2. Fault occurs when voltage is above set value for more than O/V
LEVEL 2 Delay. Range: 100 - 120 % of Un. Increments of : 1%
O/V Level 2
Delay
1 Sec.
Over Voltage Level 2 delays.
Range: 1 - 100 Sec. Increments of : 1Sec.
