Two battery chargers are available see Figure 3-2. Annual Maintenance and Testing 3-23. The pickup value is fixed at 10% of the drop-out. No special tools are required to remove and re- place control system components. Control Plate The Control Plate contains two transformers; one for Emergency supply and one for Normal supply Figure 2-13.
Electronic Control Circuit Modules 2-9. When the transfer switch is in the Source 1 Normal position, switches S2, S3, S4, and S5 are actuated. Reconnecting the Transfer Switch 3-4. The default val- ue is 10 seconds. The Power Module contains eight transformers. After the Setup is Completed 6-3.
If you are unable to locate a dealer or distributor, consult the Yellow Pages. The controller monitors each source for allowable voltage and frequency range. If the duration of in- terruption exceeds the delay time, the control sys- tem starts the generator. The Source 1 or Source 2 Available relays are en- ergized when their respective power sources are producing power. The load transfers to the generator set when genset power becomes available accept- able.
For rear seats, third door is used. Replacing Block and Cross-Bar Assembly Normal or Emergency 7-14. An open switch stops the generator. Software Versions Prior to Version 1. The InPower service tool can be used to create a capture file of all the calibration and adjustment settings in the Digital Module.
It is this level of detail, along with hundreds of photos and illustrations, that guide the reader through each service and repair procedure. Troubleshooting Using Fault Codes 6-5. Removal of the automatic trans- fer switch must only be performed by trained and experienced personnel, following the pro- cedures provided in the Sections 6 and 7. The Source 1 or Source 2 Connected relays are energized when their respective power sources are available, ready to produce power, and con- nected to the load. This delay begins when the Source 2 typically the generator voltage and fre- quency reaches the settings of the control. Bypassing Load to Normal Source 1 3-2. Jewelry is a good conductor of electricity and should be removed when working on the electrical equipment.
The Source 1 or Source 2 Connected relays are energized when the respective power source is producing power and connected to the load. After the delay, the transfer switch transfers the load to Source 2. Retransfers the load to Source 1. The vari- ous types are designated as general-purpose, in- door or outdoor cabinets. Please read this manual carefully as it will be of assistance for service and sales activities. The adjustable range for the time delay period is 0.
When contacting your distributor, always supply the complete Model Number and Serial Number as shown on the nameplate. The sensor indicates a fail- ure when the maximum deviation from the average voltage is greater than a user-specified value be- tween 2 and 10 % drop-out of the average volt- age in 1% increments. When placed in the Off position, the Not In Auto indicator on the front panel will light and the display indicates a Mo- tor Disconnect event. The load-supplying contacts of the auto- matic transfer switch are out of service, but the controller and linear actuator are powered and ful- ly operational. The exercise routine is not avail- able with this configuration.
The default value is 3 seconds. Identify all hazards by referring to the Safety Precautions and observe all warnings and cautions within the manual. Connections to these relays are made at J14 and J15 on the Relay Mod- ule. Digital Module The Digital Module Figure 2-10 contains the logic and timing circuits that control transfer switch op- eration. In the Test position, the primary isolation contacts are open and the secondary isolation contacts are closed. For utility-to-genset configurations, the exercise clock initiates generator set start and run cycles at specified intervals for specified durations.
How to Obtain Service 1-3. During this time delay, the generator set cools down without load before stopping. Movable Contact Assembly Removal and Replacement 3000 Amperes 6-25. The default delay time is 1. Typical Interconnection Diagram Sheet 3 of 10 10-11. If necessary, the switch can be lifted from its rails and removed for service.
