System internal structure & wiring

ATS contain the AMF module which can get the remote

start signal from SAM2-Gen Controller/SAU to start &

stop D.G and to make the system go into Hybrid

cycles . It can also supply alarm and D.G running information to

SAM2 to monitor the D.G status.

ATS check method How to confirm ATS bypass?

Note: If site battery can not supply power to site. Contact

authority and do the repair after the site battery is good. Step1: If Gen-set is supplying power to site by ATS, check

which by-pass method was used on GCB. 1. Is something used to close contactor? 2. Is the relay closed with manual handle 3. Was Live wire connected directly to

GCB coil? 4. Was relay normally closed contact used to supply power to GCB by changing the wire connection 5. Was negative looped to BO3? 6. Was negative looped to Fuel? Note the contactor is power ,will get in the shock

ATS wiring survey process Check the ATS manufactory and model. Record or take

photos for check report.

Check if you have wiring diagram for this type ATS,

check the wire number between wiring diagram and

practical ATS. If there is difference, correct it.


ATS wiring survey process If you don’t have wiring diagram for this type of

ATS, fill the components name and the wire

number on the typical wiring diagram according to

existing ATS in use. The diagram will help you

locate the fault part.

RS1—RELAY FOR START RC1—REALY FOR FUEL COIL RN1– RELAY FOR MCB( NEPA /MAINS)RG1—RELAY FOR GCB (GEN) RA1—RELAY FOR ALARM

Note: sometime the relay mark is wrong


ATS wiring survey process

The ATS survey wiring diagram and component

location diagram must be submitted to Huawei as

part of repair report.


Check wiring from Gen-set to ATS

GEN Interface Interface

mark



There are 6 cable from ATS to Gen-set. Wrong wiring lead to start motor and fuel solenoid damage and other accident. Check and confirm wiring properly.

#1 Battery Negative Wire--- Voltage between #1 wire and ground is 0VDC.

#2 Battery Positive Wire--- Voltage between #2 wire and ground is 12VDC. Note: Battery Positive wire connect to breaker first, then connect to AMF module, DC relay in ATS .



#3 Gen START ---From ATS connect to Gen start relay

#4 Gen Running----- From ATS connect to Gen Fuel ON relay

Confirm each wire according to below list then mark properly.

Voltage between #4 wire and battery negative 0VDC 12VDC 12VDC

#6 High Engine Temperature Alarm Wire---From ATS To High Engine

Confirm each wire according to below list then mark properly.

Check cables from ATS to SAM2-Gen Controller

Sometime the Inala Team member already connect wire to

AMF module or terminal in the ATS. These wires maybe

effect AMF module working properly. Remove these wires

and insulate each wire.


REPLACING INTELILITE AMF25/25 WITH INTELILITE 25/20 NT

BINARY OUTPUT PORTS IS 7 PORT

BINARY OUTPUT CONSISTS OF 4 PORTS FOR START AND FUEL, AND ANOTHER 5 PORTS FOR OTHER OUTPUTS


Connect AMF module and PC then use LiteEdit software to configure binary input and output port.


CONFIGURE THE PORTS (SITE WITHOUT PHCN)


CONFIGURING SITES WITH PHCN


Module parameter setting

Press the “parameter setting button” and go into “Set points” page and begin to set according to following figure
