Standard Options Contact f, g and h are closed when the switch is in position 1, 2 or 0. Contact i is closed when the switch is in Automatic mode. Contact j is closed when the switch is padlocked.

Communication Module

Installation of this module allows RS485 connection.

For standard configurations the ATI can be connected with a PC or a PLC over a maximum distance of 1500 metres, using JBUS/MODBUS protocol.

Voltage OptionsOne switch will cover common voltages.

A separate switch will be available for 277V

Power connections to change in accordance to P-P voltageChanging the Voltage OptionsCommon voltages will work with the standard switch by reconnecting the voltage sensing.The power supply should be connected to points 101/102 and 201/202 to provide 220 - 240V Ac. A separate switch is required for 277V

Inputs and Outputs

Digital ModuleVerify power applied on the electronic module power inputs terminals 101-102 or 201-202 before powering up the unit.

Setting the ATISoftware version is displayed on the unit after reset (powering up action after 3 minutes power off to discharge the unit).Product Programming is possible in Automatic Mode in position 1 when the Mains Source is available, or in Manual mode.It is not accessible when a test or an automatic sequence is activated. Programming mode is accessible by pressing and holding the validation key for 5 seconds and then entering the code 1000 Press for 5 seconds Press once to display 1 Press the Validate keyTo exit the Programming hold the validation pushbutton for 5 seconds.

2Mt: Loss of mains validation timer. Once mains has disappeared, 2Mt is started. If Mains comes back before 2Mt ends, the commutation cycle is not started. (Delay on Gen start.)

At: Generator voltage and frequency stabilisation timer. Generator needs to be stable during AT to allow transfer from Mains.

1Mt: Mains Return validation timer.Once main is back 1Mt is started. If Mains disappears before 1Mt ends, the load is not switched back to the Mains.

rot: Run on time timer. Once the load is switched back from the Generator to the Mains, ROT is started and the Generator will stop once ROT is finished

dbt: Dead Band timer. This timer is counted down before transferring the load from the Mains source to the Generator or vice versa. It allows the load residual voltage to decrease under a non critical value before transfer (Necessary in case of rotating loads).Setting range

ATI MonitoringIf lightning protectionoption is fitted, LIP menu is available.Metering is active as soon as the unit is powered up.Commutation cycles have priority over Visualisation mode and display timers count down as soon as they are active. Any value available in this mode can be kept on the screen once displayed.After commutation cycle, the display comes back to Mains voltage L1N (first variable of the mode).

Manual / Automatic Switch

Manual / Automatic SwitchTo access Manual Mode turn the front keyswitch to manual position.Do not force the keyswitchFrom Position 1 turn clockwise to reach position 0From position 0 turn clockwise to reach position 2From position 2 turn anti clockwise to reach position 0From position 0 turn anti clockwise to reach position 1Padlock is only possible in manual position.Handle must be out of its housing to padlockPadlock is possible in position 0, 1, 2.Manually pull the padlock handle to allow padlock insertion in the hole handle in automatic mode.Once in manual mode it is possible :To access programming and visualisation menusTo padlock the switchTo operate the switch with the handleTo start the Gen using test off load pushbutton.

Manual / Automatic SwitchThe automatic mode must be activated as soon as automatic starting of the generator and source switching is required after loss of mains condition.The unit integrates a power capacitor source to provide enough power during black out (loss of mains) to wait for generator starting. (It does not have power to drive the switch to zero position).Once in automatic mode it is possible:To access programming and visualisation menusTo start off load or on load testingTo start a loss of Mains sequenceTo start a Mains return sequenceAs soon as the unit is switched from Manual to Automatic mode, the automatic cycle is started.Mains and Generator voltage & frequency are verified to define the new stable position of the switch.The same table is considered after a complete power off action (Power Cap must be completely discharged = 2 minutes).

ATI OperationThis Sequence is started as soon as the switch is in automatic mode and in position 1.Position 1:Mains is availableSwitch is in position 1 (Mains)Generator is on or off

ATI Operation

ATI OperationThis sequence is started as soon asthe unit is in automatic mode and inposition 2.Position 2:Mains is not availableSwitch is in position 2 (Generator)Generator is offRetransfer Inhibit FunctionOnce the Mains supply has returned, it may be preferable not to immediately return the load from the generator to the mains.If Retransfer inhibit feature has been enabled in the programming mode, the RTI led is on (default value).Once retransfer from the Generator to the Mains is ready, RTI feature blocks the retransfer and the RTI led is blinking.It is necessary to manually press the RTI push button to start retransfer.

ATI OperationThis sequence is started as soon as the unit is in automatic mode and in position 2.Position 2:Mains is not availableSwitch is in position 2 (Generator)Generator is off

ATI Operation

ATI OperationPress and hold the test pushbutton for 5 seconds to allow test modes access.Enter code = 4000Press and hold the test pushbutton for 5 seconds to exit test mode after the test has been completed.

ATI OperationThis test is possible in automatic in position 1 when the mains is available or in manual mode.This mode allows generator testing without load transfer from the Mains to the Generator.The generator is started and stopped normallyThis test is possible in automatic or manual modeThis test is not possible when an automatic sequence is running.Press Test pushbutton to make the testoff load Led blink and press validationpushbutton to start.In automatic mode, as soon as you enter in test mode option, t on l is displayed. Press test key once for to reach test on load option.

ATI OperationThis test is only possible in automatic mode in position 1 and Mains available.This test simulates a loss of mains condition. Loss of Mains sequence is started and Mains return sequence automatically activated as soon as the genset is available.All timers operate following their set points.The retransfer inhibit feature is always activated during test on load (from keypad).Press Test pushbutton to start the test on load Led flashing then press the validation pushbutton to start the cycle, following Loss of Mains + Mains return sequences.Remote activation via remote test on load inputIt is possible to remotely start the test on load closing contacts 7 and 9 on the electronic module.The cycle is started as soon as the input is closed.The retransfer from. generator to mains is blocked, and only allowed once the input is de-activated.
