SmartGen HAT560NC Series ATS Controller User Manual

1 Overview

The HAT560NC series ATS controller is an intelligent dual power transfer module featuring configurable functions, automatic measurement, an LCD display, and digital communication. It integrates digitalization, intelligence, and networking to automate measurement and control processes, reducing operational errors, making it an ideal product for dual power transfer applications.

Built with a microprocessor core, the HAT560NC series ATS controller precisely measures 2-channel 3-phase/single-phase voltage. It accurately judges abnormal voltage conditions (over/under voltage, loss of phase, over/under frequency) and outputs volt-free discrete control signals. It is suitable for various ATS types, including specialized ATS, contactor ATS, and air break ATS. Its compact structure, advanced circuits, simple wiring, and high reliability make it widely applicable in electrical devices, automatic control, and testing systems across sectors like electric power, telecommunications, petroleum, coal, metallurgy, railways, municipal administration, and intelligent buildings.

Event log information comprises event type, 1# and 2# power supply status, 1# and 2# 3-phase voltage, 1# and 2# frequency, and the record date and time.

Table 11 Event Log Types details event types:

8 Timing Start

Access the Timing Start menu by pressing the [Set Key], selecting "Time start", and confirming with the [Set Key]. The interface allows configuration of:

• Time start cycle: Inhibit start, single, weekly, or monthly genset start.
• Load set: Start the generator with or without load.
• Start time: Date and time for genset starting.
• Duration time: Generator continuous run time (up to 99 hours and 59 minutes).

9 Commissioning

Access the Commissioning menu by pressing the [Set Key], selecting "Commissioning", and confirming with the [Set Key]. Options include:

• Exit
• Stop to Test
• Test Off-Load
• Test On-Load
• Cyc start

Test Off-Load: Initiates a start signal. If genset and mains voltage are normal, ATS does not act. If mains voltage is abnormal, ATS transfers load to the generator. Upon mains voltage recovery, ATS transfers back to mains, with the generator start signal continuing.

Test On-Load: Initiates a start signal. If genset voltage is normal, ATS transfers load to mains immediately, irrespective of mains status.

Stop to Test: Disconnects the genset start signal and stops TEST OFF-LOAD or TEST ON-LOAD operations.

Cycle Start: Outputs oil engine start signal circularly based on master status. Circular output time is user-configurable. If an oil engine fault occurs, no start signal is sent. In manual mode, it retains current status and stops circular timing.

Requirements for Commissioning:

• Automatic mode must be active.
• Set output to 1# and 2# Oil Engine Start Output (N/O).
• Set input to remote start input.
• Program <Cycle running time> and <Cycle stop time>.
• Set system type to 1# Gens & 2# Gens.
• Set appropriate <Wait Running> time (default delay 60s).

Note: In manual mode, if commissioning input is active, the generator start signal outputs immediately, but ATS transfer requires manual operation via the front panel key.

10 Date and Time Setting

Access the Date & Time Set interface by pressing the [Set Key], selecting "Date & Time", and confirming with the [Set Key]. Use the [Scroll Screen/Decrease Key] to input numbers and the [Set Key] to move bits and update the date/time.

11 Language Setting

Access the Language setting interface by pressing the [Set Key], selecting "Language", and confirming with the [Set Key]. Options include Simplified Chinese and English. Use the [Scroll Screen/Decrease Key] to select and the [Set Key] to confirm.

12 Controller Information

Access the Controller Information interface by pressing the [Set Key], selecting "Controller information", and confirming with the [Set Key]. This displays information such as current breaking positions, transfer priority, controller version, and date. Pressing the [Scroll Screen/Decrease Key] allows access to user-customizable information pages.

13 ATS Operation

13.1 Manual Operation

When the manual mode indicator is on, the controller is in manual mode. Use the following keys:

• Press [1# Close Button]: 1# close relay outputs; if 1# close input is active, 1# power supply connects to load.
• Press [2# Close Button]: 2# close relay outputs; if 2# close input is active, 2# power supply connects to load.
• Press [Open Button]: 1#/2# open relay outputs; if 1#/2# close input is inactive, the respective power supply disconnects from the load.

Note: Pressing the [Open Button] is invalid for ATS without a neutral position.

13.2 Automatic Operation

When the auto mode indicator is on, the controller is in auto mode and can automatically transfer to 1# or 2# load.

13.3 ATS Power Supply

The controller smartly provides ATS power. Normal ATS operation requires at least one channel with normal voltage.

Users select power supply voltage (phase or line) based on ATS type. For phase voltage power, connect the phase voltage (A phase) of 1# and 2# to Terminal 8 (N/C) and Terminal 10 (N/O) of programmable port 3. Connect the N phase of 1# and 2# to Terminal 13 (N/C) and Terminal 11 (N/O) of programmable port 4. Connect the COM of programmable ports 3 and 4 to the ATS power supply. After powering on, configure port 3 as "ATS power A phase" and port 4 as "ATS power N phase". For line voltage supply, the connection is similar, only changing the N phase connection and port 4 configuration.

Diagrams illustrate ATS phase voltage power supply and ATS line voltage power supply connections.

Note: Normally Close (N/C) input voltage must come from 1# voltage.
