-General-

ATR automatic phase changeover relay is designed to switch the fault phase to the normal phase from errors that:may arise from mains high and low voltage.

-Device Usage and Principle of Operation -

Make the connections of the device according to the connection type. Otherwise, the device may be damaged. Adjust the over-current andhigh & low voltage and settings of the device according to the coperating current and voltage values of the load you will use.

High Voltage Error state:
If the used phase voltage value is over the high voltage set values the device waits for the 3sec.(fixed), then the device de-energizes the relay, the V>led turn on, the high voltage value displayed on the screeflashes throughout the error period.
The device waits for the set time of D-T to switch to another normal phase and energizes the relay.

Low VoltageError state:
If the used phase voltage value is under the low voltage set values the device waits for the 3sec.(fixed), then the device de-energizes the relay, the V< led turn on, the low voltage value displayed on the screen flashes throughout the error period.
The device waits for the set time of D-T to switch to another normal phase and energizes the relay.

Common phase settings:
when set to cyclical the current phase is maintained when the current phase is not faulty. When the curren phase fails, switch to the next fault-free phase and hold.

-Display and Buttons-

1 - Low voltage setting knob

2 - High voltage setting knob

3 - Changeover delay setting knob

4 - Common phase setting knob

5 - Manual On/Off Button:
For close the device output. In this state, the screen will display "off" and the device cannot be automatic changeover. Press this button again toswitch on the device intouse again.

6 - Voltage Display
Display Group: During normal operation, the input voltage value isdisplayed here, the screen lights up steadily when not in error state, the display flashes in case of error (high or low Voltage).

7 - LEDs:
L1 (U>): Lights up when L1 phase has high voltage fault.

L2 (U>): Lights up when L2 phase has high voltage fault.

L3 (U>): Lights up when L3 phase has high voltage fault.

L1 (U<): Lights up when L1 phase has low voltage fault.

L2 (U<): Lights up when L2 phase has low voltage fault.

L3 (U<): Lights up when L3 phase has low voltage fault.

-Working-

Example: Set the low voltage value(U<) to 160V, the high voltage value(U>) to 260V, and the time of Changeover delay time is 5 sec. Set the common is cycle.

Make the connections of the device according to the connection type.L1 is trouble-free and energizesrelay, led is turn on, output led is turn on.

When the L1 voltage is under 160V, the delayis 3 seconds(fixed), cut off the L1 phase and ( L1 U<) error led turn on, turn on the fault-free L2 phase after the delay of D-T (5 sec.), theled turn on, and the output led is turn on.

When the L2 voltage is over 260V, the delay is 3 seconds (fixed), cut off the L2 phase and( L2 U>)error led turn on, turn on the fault-free L3 phase after the delay of D-T (5 sec.), theled turn on, and the output led is turn on.

When the L3 voltage is over 300V, the delay is 3 seconds(fixed), cut off the L3 phase and( L3 U>)error led turn on. In this state,L1,L2, and L3 are all faulty, disable the output, wait for any one phase to return tonormal, and then turn on the load again.

-Warnings-

Please use the device according to the manual.
Don't use the device in wet.
lnclude a switch and circuit breaker in the assembly.
Put the switch and circuit breaker nearby the device,operator can reach easily.
Mark the swith and circuit breaker as releasingconnection for device.
