Page 4: Section 1 - Introduction
(utility), the transfer switch system transfers the load to the secondary (generator) source. Once utility power is restored to the home or building, the transfer switch transfers the load back to the normal source, and initiates generator engine shutdown. -
Page 5: Standard Configurations
Incorrect connection of a central air conditioning/heat pump system to an OVATION™ Series ATS can be dangerous, and may cause damage to the transfer switch, generator, or air conditioning/heat pump equipment, and will void all warranties. Late model (2007+) air conditioning/heat pump compressors may require modification with Hard Start Kits to ensure proper startup under generator power. -
Page 6: How The Ovation™ Series Automatic Transfer Switch Works
1) When the utility power fails or drops below 190 volts or 54 Hz or exceeds 280 volts or 66 Hz, the OVATION™ Automatic Transfer Switch will begin the generator starting sequence after a 5-second delay. 2) Once the generator is started, the system is programmed to allow the generator to warm up and wait for possible successful utility power grid re-strike (approx. -

- Page 9 Up to 6 connected loads based on parameters set up at installation are actively managed to optimize generator capacity utilization. As generator power capacity becomes available, the transfer switch will attempt to turn on each load controlled by PowerPause™ Load Management until the generator reaches 85% output utilization. Ideal for seasonal (i.e. air conditioning, pool equipment, etc) or intermittent (i.e.

Call Factory if your installer needs the UL file number. Each OVATION™ Series ATS complies with NFPA 70 (National Electric Code) Article 702 as an “automatic transfer switch for use in Optional Standby Systems.”... -
Page 11: Section 2 - Compatible Equipment
SECTION 2 – COMPATIBLE EQUIPMENT 2.1 Compatible Generators In order for the OVATION™ Series ATS to function as designed, it must be connected to a permanently installed, automatic starting generator, with a continuous supply of fuel, such as gasoline, diesel, LPG or natural gas. Additionally, gasoline or diesel-powered generators must be equipped with automatic choke and electric/remote start. -
Page 12: Section 3 - Preparing For Installation
Standard, Arc-fault, GFCI or Surge protection circuit breakers for branch circuits. If Arc-fault, GFCI or Surge protection circuit breakers are used as the branch circuit protector in the main load center, they MUST be used in the transfer switch. See Section 2.2 for compatible breakers. - Page 13 NOTE: Critical loads that MUST operate when required should NOT be connected to a PowerPause ™ Load Management Module. It is recommended that the generator and transfer switch be sized properly to power ALL critical loads without the need for load management.
- Page 14 Examples of critical loads that are NOT recommended (NOT OK) to be connected to the PowerPause ™ Load Management Module and Relay Box are: • Refrigerators and freezers • Aquariums • Central heating systems (gas, oil, electric) • Furnace fan (air handler) •...

Page 18: Standard Mounting Procedures
4.1 Standard Mounting Procedures 4 .1.1. As Service Equipment and/or primary Load Center Panel: Models ATS1001D/R, ATS2001D/R or ATS2002R: When using the transfer switch as Service Entrance Equipment, mount the OVATION™ Series ATS as close as possible to the utility meter. - Page 19 4.1.2. As a Generator subpanel: Models ATS1001D/R: If using the Ovation™ Series ATS as a generator sub panel, mount the transfer switch as close to the load center as possible. The OVATION™ ATS can be installed on either the left or right side of the load center. If flush-mounting is desired, the OVATION™ ATS can be mounted in the adjacent stud space next to the existing load center.

If the generator is a 2-wire control system, use a 3-wire conductor to ensure a -12VDC signal is wired to the transfer switch on PIN 1. If 3-wire conductor is not available, install a jumper between PIN 1 and the ground bar in the OVATION™... -
Page 21: Connecting The Low Voltage Cable To The Generator
Some generators use 2, others 4 control wires. Refer to the generator installation manual for proper connection. Connect the PIN 1 wire from the transfer switch to the battery “–“ (negative) terminal. If there is no battery terminal block, run the PIN 1 wire to the “–“... - Page 22 Hold at 30° angle, push onto bus stabs c. Lower outside end flush with enclosure. d.

Page 25: Section 6 -Startup And Testing
Turn OFF the service equipment disconnect in the transfer switch or feeding the transfer switch. This will simulate a utility power interruption. After a 5 second delay, the OVATION™ transfer switch will attempt to start the generator. Use a digital volt meter to verify generator voltage at GENERATOR MAIN circuit breaker lugs. Verify the following: Turn ON service disconnect that was turned OFF in Step 1 above. -
Page 26: Re-Installing Covers And Labeling Circuits
1) Determine where branch circuit breakers have been installed and remove the required dead-front twist-outs. All dead-front openings must be covered with circuit breakers or with filler plates. Order GenTran PN 51022 for additional filler plates. 2) Install dead front cover on enclosure with screws provided. For Models 1001 and 2001, any excess openings between circuit breakers and twist out openings must be corrected by adjusting the two screws on the inside of door or adjusting the depth of the box. -
Page 27: Section 7 - Troubleshooting
Check generator oil level alert and refill reservoir if necessary. Check generator battery for low or dead cell. Check all power cord and cable connections. Generator main circuit breaker (on generator) should be in the ON position and run switch should be in AUTO position. 7.2 Troubleshooting Guide PROBLEM POSSIBLE CAUSE A. - Page 28 1. Reset computer by pressing RESET button on controller module. (Note: User custom programming is retained in ROM) 2. Replace Control Module. Call GenTran. 1. Change to desired delay. 2.
