SECTOIN 1: INTRODUCTION 1.1 Preliminary Comments and Safety
Precautions
This document covers installation, operation and maintenance of the ATS-34 Automatic Transfer Switch Controller. This manual is for the use of authorized and qualified personnel only.
WARNING
High voltage can kill.
1.2 Product Overview
The ATS-34 controls the second ATS in a redundant emergency ATS system that works with two backup Gensets. A redundant ATS system consists of two ATS, the first ATS being a standard ATS (Normal-Emergency) that triggers the second ATS (GEN-1 – GEN-2) by using the ATS-34 control. This second ATS control selects which backup generator is the first to run and in the case of a fail start or a breakdown restores power by switching to a second generator. This line circuit illustrated how it works.

The ATS-34 Controller provides programming flexibility for the two backup generators. Therefore, the ATS switch operates properly through a series of sensing and timing functions.
ATS-34 controller allows you to control the generator duty cycle and alternate operation of the two generators.
The ATS-34 control unit features:
● Microprocessor based with touch screen ● Compact with easy to understand LED display. ● Programmable for cycle-mode or fix-mode displays
for 3-phase and 1-phase voltages and frequencies. ● All programming and operations are done from
the front screen interface. ● Monitors over and under voltages for both
primary and secondary generators ● Monitor over and under frequencies on both
generators. ● Dry-contact alarm for transfer fail and
over-cranking ● Manual forced-bypass ● Compatible with almost all ATS switches ● Optional USB / RS485 / Ethernet remote (mobile
proxy) communication functions. ● Program on-site or from remote (mobile) device
(PC, Smart Phone). ● Auto-saved settings (memory preserved
throughout all power disconnects and resets) ● Front panel display provides source status and
fail alarm indications.

1.3 Functions / Features
The primary function of ATS-34 controller is to monitor power sources and provide the necessary intelligence to operate a seamless and automatic transfer of load between two generators.
1.3.1 Operational Simplicity
The design of the ATS-34 PLC simplifies routine operation and programming.
1.3.2 Standard Features
All logic settings for different ATS’s are preprogrammed and stored in its non-volatile random-access memory (NVRAM), this memory retains its information when power is turned off. Some features and set points are user adjustable.
Feature 1: Generator Duty Cycle – start attempts settings
You can program the ATS-34 to switch the lead generator duty by time or start-run attempts. When the working generator times out, or runs a number of times the ATS-34 starts the next generator and makes this one the lead generator. (See lines 3 & 4)
Adjustable Duty Time range: 0 to 250 Hours or
Adjustable start attempts 1 to 10
Feature 2: Transferring Time Delay
The ATS-34 controller provides a time delay when transferring from one generator to the other. Countdown begins when the standby source becomes available. (See line 5)
Adjustable time delay range: 0 to 250 sec
Feature 3: Time Delay Engine Cool-down
Controller permits the generator to run unloaded (cool down) after transferring to the other generator. Countdown starts when the transfer is completed. (See line 6)
Adjustable time delay range: 0 to 250 sec
Feature 4: Time Delay OFF Position Time Delay on OFF stops the switch in the center OFF position (completely disconnected) before transferring to the other generator. (See line 7)
Adjustable time delay range: 0 to 99 sec
Feature 5: Under / Over voltage Sensing
The controller monitors the output voltage for both generators. You can set the working voltage window on lines 8, 9, 10, 11, 15, & 16
Adjustable Over voltage range: 110VAC to 520VAC
Adjustable Under voltage range: 80VAC to 470VAC
Feature 6: Under / Over frequency Sensing The controller also monitors the Hertz for each generator. (See line 12, 13, 14, 18, & 19)
Adjustable Over frequency range: 51Hz to 75Hz
Adjustable Under frequency range: 40Hz to 59Hz
SECTOIN 2: OPERATION PANEL 2.1 General Familiarize yourself with ATS-34 hardware:

Bypass Touch Button ● Press to force a transfer
Decrease/Selection Touch Button ● Press to decrease value ● Press for Volt / Duty / Freq display
2.3.1 Increase (▲) Button
When the ATS-34 controller is in AUTO, each touch of the up arrow (▲) changes the display to the next phase voltage reading.
When in programming mode, each touch of the Increase (▲) key scrolls through all available parameters. When touching and releasing the increase (▲) button, the displayed parameter changes and increases in single units. The Increase (▲) button will continue to scroll when held down.
2.3.2 Decrease (▼) Button
Under AUTO operate status; each touch of the decrease (▼) button will change the real parameter display between voltage, duty time, and frequency.
When in programming mode, each touch of the decrease (▼) key will scroll through all available parameters. When touching and releasing the decrease (▼) button, the displayed parameter changes and decreased by one value at a time. The decrease (▼) button will continue to scroll if it is pressed and held down.
2.3.3 Auto Key
When selecting the AUTO key, the ATS-34 runs in automatic mode, lighting the LED under AUTO. The controller automatically starts the generator, transfer and retransfers from source to source as commanded by the preprogrammed settings.
In AUTO, all anomalies are accompanied by its matching alarm output; make sure all failures are corrected before touching the auto key to reset the alarm signal.
WARNING
When any failure occurs at its duty time, the controller will shut down the engine, sound an alarm output and switch to the other generator. The failed engine will not start again unless the user manually resets the alarm output by touching the AUTO key.
2.3.4 Bypass Function Button
The Bypass button provides for a manual override of pre-programmed functions. When the ATS-34 is in AUTO, touching the Bypass key ignores the current timers and setting, and the controller will force-start the second generator and transfer the switch from the current working generator to the second generator. The Bypass function can be activated only in AUTO.

2.3.5 OFF Key
Touching the OFF key, turns the ATS-34 OFF engaging a flashing red LED instantly disabling all functions.
However, in program mode, touching the off button allows the user to change to the next program line to set new parameters using the decrease (▼) or increase (▲) button.

SECTOIN 3: OPERATION
3.1 General
This section describes the operation and functions of the ATS-34 controller. It is divided into four main categories:
● Automatic mode ● OFF mode ● Bypass mode ● Programming mode
The use of each operation under each category will be explained in this section. It is assumed that prior sections are understood, and the operator has a basic understanding of the hardware.
3.2 Auto Mode
The AUTO mode of the ATS-34 controller provides for automatic start, stop, and transfer and retransfers from source to source as dictated by the programmed values.
The ATS-34 constantly monitors the condition of both generators providing the intelligence for transfer operations.
3.3 OFF Mode
In OFF the ATS-34 disables all the transfers and protection functions, the display window and all the LEDs are turned off.
Both remote start signals are also disabled in OFF and the ATS cannot transfer the load to any source automatically.
However, in program mode, touching the off button allows the user to change the program line table and set the selected parameter using decrease (▼) or increase (▲) button.
3.4 Bypass Mode
If the ATS-34 is running in AUTO, pressing the bypass button ignores its current duties and force starts the next generator, and transfers power from this generator to the other. If the second generator fails to start or its voltage and frequency does not become available, the controller keeps the load connected to the working generator and triggers an alarm.
Activate the Bypass only when in AUTO.
3.5 Programming Instruction The controller is fully programmable from the front faceplate.
To get into programming, set the control-to OFF and press and hold the OFF button for 4 seconds. The word “Vr1.0” appears on the display window for 2 seconds, indicating the software version.
Now you are ready to start the line-by-line programming sequence. Press the OFF key to advance to the next programming line. To change each parameter, press the increase (▲) or the decrease (▼) keys. When pressing and releasing the increase (▲) or decrease (▼) key, the displayed parameter can be increased or decreased by one unit. The Increase (▲) or decrease (▼) will continue to scroll if it is pressed and not released.
Always press the “OFF” button to advance to the next programming line or until the word “End” appears on the screen. Note: To end and exit at any time, simply hold the “OFF” key for 4 seconds.
If you make an error or need to return to factory settings; stay in or reenter programming mode and simultaneously hold the AUTO keys for 4 seconds, until the word “Au.Po” appears on the display confirming all settings are reset to factory. (See line by line programming table for ATS-34 factory settings).
