YEQ***3 type auto transfer switch(shorten as ATS) is suitable
for dual power supply system of AC *0Hz, rated operational voltage
**0V and below, can complete the switching over between normal
source and standby power source through automatic or manual
operation mode. The switch is mainly applicable to important places
such as hospital, store, bank, chemical industry, metallurgy,
high-rise building and military installations where power off is
forbidden
Use of Operates and supports
Whether main power or backup power with voltage or not, all
can be by manual mode operated.Under manual, put the auto- manual
button to manual position, pull the handle by clockwise to
end, Backup power implementation circuit breaker Qr is OFF,
implementation of MAIN power supply circuit breaker Qn ONg; When
pull handle counterclockwise to the end, the implementation
of Backup power source Qr is ON, implementation of MAIN power
supply circuit breaker Qn is OFF;Set the auto position, if the MAIN
power is normally, ATS will transfer to MAIN power
working. The MAIN POWER indiacation will bright on panel;If
the MAIN power is unusually, ATS will transfer
to Backup Power ***** Backup indication will be bright on the
panel.
ATS has 1A of two units fuses and a
electric connector, fuse as short-circuit protection in automatic
***** connecto as dry contact in Indication light to
panel of controller box, voltage of **0V AC, l*0mA , the
detail please reference to instruction.
Fault Analysis and Removal
When ATS under automatic control state, the POWER condition
was changed, but the operation mechanism no action. Such as
MCB can`t closed-transition or open-transition, then should be
checked:
(1) whether the power grid are failured;
(2) whether the wiring shedding;
(3) the fuse itself whether burning. If the front point of one
circuit breaker with electricity, and the connection are botht
wiring well, fuses are intact, but yet can not
closed-transition or open-transition.You should be asked to
professionals or contact manufactory.
