Introduction

Clipper ATS Model No.SF25, SF50, SF75, SF100, SF200, SF300, SF600, SF1200, SF2000 & SF3000 are fully automatic generator Control Unit. It is designed to control Single fuel such as Natural Gas or Diesel power generators. Clipper ATS SF series is not suitable for any generator that needs to pull choke as the design does not offer any mechanism for pulling the choke, which is required in most Petrol or dual fuel generators. Clipper ATS SF series can be used in Auto or Manual mode. Upon power ON Auto mode is selected by default. User can change the mode of operation to Manual by just pressing Manual button on control panel. In Auto mode, Clipper ATS does not require user intervention. It automatically turns ON the generator upon Utility/Grid power failure. And will turns the generator OFF when utility/Grid power resumes. This also includes automatic Load switch from Utility power to Generator and from Generator to Utility/Grid power; thus eliminating the need of any external change-over switch. In Manual mode Clipper ATS observes all the events such as Utility/Grid power failure, the status of Generator and Transfer relay/contactors etc. It will show the status of all events on LCD display, but it does not act upon any event by itself; rather it will wait for user to command the system by pressing appropriate button on front panel. i.e. Generator ON/OFF button, Generator START motor ON/OFF button, Load transfer change-over button. There are five push buttons and 7 LED indicators on the control panel. Each Push button has dual function. Table1 and Table 2 shows the description of each one.

Installation

Installation of Clipper ATS/AMF is straight forward. However to further simplify we divide it into 3 major areas.

1- Generator Side wiring. 2- Electrical Wiring. 3- Customizing through setup procedure.

Generator side wiring. Generator will be connected to the Clipper ATS power board via UTP5 8 core cable with the help of RJ45 8pin networking connector. Since the UTP5 cable has 8 core cable, however Clipper ATS system requires only 4 connecting wires, therefore, we used two wires in parallel in place of one. This offers further strength to the signal and DC power thus allow longer distance between generator and Power distribution cabinet. Please refer to table3 for RJ45 connections on power board side.

Table3. RJ45 connector and UTP5 cable connections User should get RJ45 connector crimped with UTP5 cable on one side with the above recommended color codes. On the other side of the cable, remove the UTP5 outer jacket for around 2 to 3 feet length and connect them firmly to the generator


locations described in Table3. We suggest you to wrap the connection with electrical insulation tape and later tie them with cable tie wherever it is required and suitable. Please do not connect the RJ45 connector to the Power board at this time. Wait for this until all other electrical connections has been finalized. After you have done this, your first step of installation is completed. Electrical Wiring: Electrical wiring is a vast topic and may differ for different models of Clipper ATS. For Clipper ATS Model SF25 it is relatively straight forward. Model SF25 is designed for single phase generators rated up to 2.5kvA. This model is designed for cost effective single phase implementation of ATS and AMF function for simple house-hold application. It uses built-in SPDT hi-power relay for switching the load between Utility/Grid supply and Generator output power. This saves money and offers affordable ATS solution for low-cost generators. Please refer to Figure1 to understand electric wiring connections for the model SF25. Other higher models of SF series such as SF50 to SF300 uses external multi-terminal Contactors for switching the power. Using contactors allows the higher power loads to be switched when Utility/Grid supply fails and resumes. The electrical wiring of the higher models requires good understanding for Electricity. It is not recommended to install this portion for a regular user rather we highly recommend to hire some professional to carry out the job for them. There could be 4 possible electrical wiring combinations to connect Clipper SF series ATS system. Please refer to Table4 to summarize all 4 wiring combinations.

Figure1. Single phase Grid-Single phase generator. In Figure1 wiring layout, no external high power contactor is used, therefore the load will be on to the relay installed on ATS power board. That relay can only with-stand with 2.5KVa load maximum. Therefore regardless of supply limit from Electric company, total LOAD should not exceed from 2.5kva maximum. Safety circuit breakers are not shown in the schematic and can be implemented according to the specific requirements. In this wiring scheme only high power single phase selector switch can be installed.

Figure2. 3Phase Grid-Single phase generator. This wiring can be used for the following Loads Load on L1 = Maximum 2.5KVa. Load on L2 and L3 = Maximum available supply load. In Figure2 wiring layout, no external high power contactor is used, therefore all load on L1 will be on to the relay installed on ATS power board. That relay can only with-stand with 2.5KVa load maximum. Therefore Load on L1 should not exceed from 2.5kva maximum. However, L2 & L3 are directly supplied to the Load therefore L2 & L3 can be loaded with any capacity of Load which is supplied by the Electric company. Safety circuit breakers are not shown in the schematic and can be implemented according to the specific requirements. In this wiring scheme only high power single phase selector switch can be installed.

Figure4a. 3Phase Grid-3phase generator. From 10KVA to300KVA Wiring diagram. Safety circuit breakers are not shown in the schematic and can be implemented according to specific requirements. Please note the high power 3phase selector switch implementation to by-pass the ATS. In the case of emergencies ATS can be by-pass by implementing Selector switch. Selector switch can be installed in all other wirings shown from Figure1 to Figure4. Selector switch can be a high power 3 phase switch or can be small, very low power. Both work in the same manner as far as ATS by-pass is concern. In high power selector switch implementation, all power to the LOAD will be supplied through selector switch itself. ATS as well as Magnetic contactors do not take part in supplying the power to the LOAD. Whereas in low-power Selector switch implementation, ATS is by passed, but all power to the LOAD will be supplied through magnetic contactors.

Figure4b. 3Phase Grid-3phase generator. From 10KVA to300KVA Wiring diagram. Safety circuit breakers are not shown in the schematic and can be implemented according to specific requirements. The schematic in Figure4b is same as in Figure4a, but in figure4b selector switch used isa single phase very low power one. Change-over switches shown in schematics are optional and are not included with the Clipper ATS systems package. System can work without any problem even if change-over switches are not installed. However they might be recommended if ATS by-passing is required. This will offer the possibility to Manually switch the LOAD to the Generator or to Utility/Grid supply in the event of any problem with ATS or its related other items or wiring.


Customizing through setup procedure . Every generator brand and model might behave different from each other while starting and loading. Therefore ATS should be configured with appropriate procedure and delays for every event during starting procedure and during Loading. Traditional Electrical ATS are mostly designed based upon static timer-driven relays. To setup and configure such ATS requires experience and a lot of patient as it takes a lot of time. Mostly timers used in those traditional ATS are dependent upon variable analog settings through a round knob. Therefore they could not be adjusted easily and accurately. To setup such Traditional ATS we need to call a professional which costs extra time and money. Clipper SF series ATS offers great flexibility to customize it for many different brands of generators with different operating behavior. Clipper SF series ATS are equipped with a powerful setup program where user can customize it according to specified generator’s requirements. Clipper SF series ATS has 5 button control panel and a 20x2 character LCD alphanumeric display with backlit. User can easily setup all different types of parameters and delays using the setup routine which guides the user through a step by step menu. In the following section you will be shown an step by step tutorial for setting up custom parameters.

Getting into setup: 1- To enter into setup mode, press Manual/Setup button for 5 seconds. As

soon as 5 seconds completed, the following message will show on the LCD display. 'Press > to restore' ' factory settings'

Please note that if you remove the finger from the Manual/Setup button before 5 seconds and before the above message appears on LCD display, system will go into Manual mode which will be shown by Lighting up the Manual LED indicator. Should this happen, you will have to come out from the Manual mode by briefly pressing the Manual/Setup button again, Manual LED will turn OFF. Now start over from section 1 again.


Upon appearing 1st menu item, which gives the option to restore factory defaults, if user press Right Arrow key > all settings will be reset to its original factory default settings. This facilitate to re-start from fresh. If reset to factory default option is not needed, please press down arrow key in order to proceed the next setup item. Note: Exiting from setup is possible at any moment. If needed, press Manual/Setup button and system will come out from Setup mode into Auto mode after Saving user entered parameters if entered any.
