1 OVERVIEW
HAT530NC ATS Controller is composed of the core microprocessor, which can precisely measure 3-phase/single phase voltage of 2 ways, make accurate judgment on abnormal voltage (power lost, over/under voltage, over/under frequency, loss of phase, phase sequence wrong), and control ATS to transfer after delay is expired. This controller is suitable for NO Breaking ATS and ONE Breaking ATS. When #1 power is abnormal, the controller will send signal to start genset after the “#1 abnormal delay” has expired. “Three remotes” (remote control, remote measurement and remote communication)
functions can be implemented with the help of RS485 communication port.

Note 1: Each time the controller is power on, the main use status of the controller can be judged by the following three conditions.
If the 1# power indicator flashes 3 times rapidly, the #1 power is main use.
If the 2# power indicator flashes 3 times rapidly, the #2 power is main use.
If 1# & 2# power indicators flash 3 times rapidly at the same time, they are mutual- backup.
Note 2: Each time the controller is power on, the AC line system of the controller can be judged by the following four conditions.
If 1# close indicator is light on, it is 1P2W;
If 1# close indicator, manual status indicator and 2# indicator are all illuminated, it is 3P4W. If 1# close indicator and manual status indicator are illuminated, it is 2P3W.
If 2# close indicator and manual status indicator are illuminated, it is 3P3W.
Note 3: Each time the controller is power on, the auto trans. auto restore/auto trans. non-restore status of the controller can be judged by the following 2 conditions.
If 1# power indicator and 1# close indicator flash 3 times rapidly at the same time, it is auto trans. non-auto restore status.
If 2# power indicator and 2# close indicator flash 3 times rapidly at the same time, it is auto trans. auto restore status.
Note 4: When the remote adjustment is disabled, PC cannot write parameter configuration to host computer.
Note 5: The factory default value is 1# power and 2# power abnormal delay for 5s, the genset will stop delay for 90s.
Note 6: 1# power abnormal delay: adjust the potentiometer (on back panel) of “1# power normal delay”; 2# power abnormal delay: adjust the potentiometer (on back panel) of “2# power normal delay”; the set value of 1# power normal
delay should greater than or equal to the set value of 1# power abnormal delay, otherwise 1# power normal delay value will be forced set to the set value of 1# power abnormal delay; the set value of 2# power normal delay should greater than or equal to the set value of 2# power abnormal delay, otherwise 2# power normal delay value will be forced set to the set value of 2# power abnormal delay;
Note 7: When parameter is set to restore the factory default setting and delay adjustment, press button and press button again; when the indicator of setting item No. flashes, press button to save the configuration.

OPERATION CONTROL
When controller is running, pressing key can set the controller as Auto mode or Manual mode (indicate by automatic and manual indicators).
In Auto mode, controller can transfer the load to 1# or 2# power. When it is set to Auto Trans. Auto Restore, master power is normal, and controller will transfer to master power end in priority; When it is set to Auto Trans. Non Restore, controller only transfers to backup power, and master power transfer can only be controlled manually. Each Backup is for two powers to be backup for each other. When 1# power is abnormal, and 2# power is normal, switch will transfer to 2# power supply, and vice versa. When it is set to Each Backup, controller will not detect auto trans. auto restore settings.
In Manual mode, press key, load will be transferred to 1# power supply; Press to disconnect load supply; and press key, load will be transferred to 2# power supply.

RS485 CONNECTION DESCRIPTION
Connection between RS485 and adaptor is as below:
Fig. 4 – RS485 Connection Diagram
ATS POWER SUPPLY
The power of ATS is supplied by controller smartly, as long as one voltage is normal, this can ensure ATS power supply normally and can be transferred properly.
Users should select power supply voltage (phase voltage or line voltage) based on ATS type. If choose phase voltage, connect the phase voltage of 1# and 2# (e.g. A phase) to normally close (Pin3) and normally open (Pin1) contact of auxiliary output 1; connect N phase of 1# and 2# to normally close (Pin4) and normally open (Pin6) contact of auxiliary output 2. And then connect the common output of auxiliary output 1 and auxiliary output 2 to ATS power supplies. When controller power is ON, the default configuration of auxiliary output 1 is “ATS power A” while auxiliary output 2 is “ATS power N”. If the ATS power supplied by Line Voltage, same procedures as above but change phase N to phase voltage and the auxiliary output 2 should be configured as “ATS power B”. Parameters can be set via PC software. Wiring diagrams are shown as following:
Fig. 5 – ATS phase voltage and line voltage power supply
NOTE: If there is no need to control ATS Power Supply, then the above terminals are not connected and the Auxiliary Output 1 and Auxiliary Output 2 should be set as “Not used”. If the Auxiliary output 1 and Auxiliary Output 2 are used for something function other than the “ATS Power Supply”, corresponding function items should be set.

NOTE: The diagram is for reference only. The actual wiring shall follow the ATS instruction. Users should choose proper fuse capacity according to the actual power consumption. If SOCOMEC VS is applied, the Close delay and Open delay must be no less than 5s (Default: 5s).
