6-5 Start functional setting automatically
■ PE is not 0, please permit to restart function automatically. This function is only for external control
two-wire mode, it is not controlled by PD. It is set at closing and starting according to the connection of
two-wire mode.
■ It delays for 60s when power is on, then it will start again automatically.
■ P5 set time is more than 60s, pleas delay though pressing P5 set time. The indication lamp flashes at
delaying state.
■ It can start for n times, besides starting when power is on and restarting after occurring the fault,
" "
" "
n is the PE set value.
■ Automatic restarting doesn't effect until it is started, it still effects if switch on every time.
This soft starter possesses the loss-voltage protection function, it says that the power is
off but power is on later, wherever the external terminal is, it can't start automatically, in
order to prevent the injuring accident. When automatic restarting is permitted, the power
failure protection is unavailable.

9 Protection function
9-1 Instruction of protection function
series has perfect protection function, in order to safe to use. During using, please
AJR3-1000
set the protection grade and protection parameter properly according to different situations.
Over-heat protection: When the temperature rises at 805, it causes the protection action,
when the temperature falls at 55 (min), the over-heat protection is removed.
The lag time of input open-phase protection: Less than 3s.
The lag time of output open-phase protection: Less than 3s.
The lag time of three-phase unbalance protection: Less than 3s. Base on the declination of
each-phase current more than 50%, when the load current is lower than 30% of nominal rated
value of soft starter, the reference declination decided is increased.
Time of over-current protection at starting: The time of protection that when the duration is
more than 5 times of 7 max working current is shown in P15:19-2-1table.
P
Time of over-load protection at running: Basing on the 7 max working current, it runs the
inverse time lag protection, the curve of protection is shown in P16:9-3-1.
Lag time of over-low protection of supply voltage: When the supply voltage is lower than 40%
of the limited value, the protection action time is less than 0.5s, otherwise, this protection
action would be less than 3s when it is less than this value.
Lag time of over-high protection of supply voltage: When the supply voltage is higher than
130%, the protection time is less than 0.5s, otherwise, it is higher than this value, the protect-
ion time is less than 3s.
Lag time of load short-circuit protection: Less than 0.1s, the current is more than 10 times of
nominal rated current of soft starter.
Above parameter that is from detecting the effective signal to send the release protection order,
the parameter is only for reference.
In case that the protection function of soft starter doesn't meet the user's requirement, please add
special protection equipment.
