Thetransfer scheme could be a solenoid or motorized operated ATS or a breaker pairtransfer scheme.The PMCP maintains power to the load when an acceptable normal or emergencysource is available. The frequency and voltage on both sources are monitored foracceptability. The frequency can be programmed for 50 or 60 Hz operation andthe voltage sensing can be programmed for single or three phase operation(120-600 volts).The PMCP contains three relays: the Engine Start Relay (ESR), the Normal SelectRelay (NS), and the Emergency Select Relay (ES). The normally closed contactsof the ESR provide the engine start signal. These contacts are also referred to asthe Engine Start Signal (ESS).The NS and ES relays control the transferring of the load to an acceptable normalor emergency source.The PMCP contains four connectors and a 26 position terminal block as shown inFigure 1. The J1 Connector contains the 3 -phase voltage sensing of the Normal andEmergency sources and the transfer switch control contacts from the NSand ES transfer control relays. The J2 Connector contains the transfer switch position (they are Form Cdry contacts from the transfer switch). J2 also contains the ESS contactsfor the engine start (Form B contacts) and inputs from the CT output. The J3 Connector is a standard ribbon cable connector used to interface tothe ETC Add-On Panel accessory. The J4 connector is a RS232 serialcommunication port used to interface to a laptop, the ETC Display Panel,and the ETC Handheld Programmer. These signals are standard RS232signals. A 26 position terminal block is provided for accessing the features withinthe PMCP Controller. These features are inputs and outputs. The inputsare activated by connecting the input to 24 Vdc ground and the outputsdrive 24 Vdc leds and 24 Vdc relays.4

Ifthe normal source fails for more than a predetermined time (Momentary OutageDelay), the PMCP shall signal for the engine generator to start by closing the ESScontacts. The PMCP shall sense the emergency source for acceptability. Once theemergency source has reached acceptable voltage and frequency and ismaintained for a predetermined time (Transfer to Emergency Delay), the PMCPshall signal for the transfer switch to connect the load to the emergency source ofthe transfer switch.The PMCP shall keep the load on the emergency source until the normal sourcereturns. Once the normal source has restored back to acceptability and ismaintained for a predetermined time (Transfer to Normal Delay), the PMCP shallsignal for the transfer switch to connect the load back to the normal source of thetransfer switch.After the load has been reconnected back to the normal source, the enginegenerator is allowed to run for a predetermined time (Engine Cool Down Delay).Once the delay has expired, the PMCP energizes the ESR relay to shut down theengine.1.3SpecificationsOperating temperature:Operating voltage range:Operating Frequency:-20 to 60 C120 – 600 VAC (3 phase on both sources)50 or 60 HzMeets EIA standards RS232 and RS485Controller dimensions:9.0 x 10.5 x 3.75 inchesController Weight:11 poundsPower consumption:50 VAExternal 24 Vdc current draw:100 MANS & ES contact ratings:ESR contact ratings (ESS):600 VAC @ 3 amps 3/4 HP120 VAC @ 13 amps 1/3 HP277 VAC @ 13 amps 1.2 HP24 VDC/240 VAC @ 5 amps6

A Form C configuration must be provided tothe J2 Connector of the PMCP as shown in Figure 2.If the position is incorrect, the PMCP shall activate a transfer switch failure alarm andthen go into a shutdown or sleep mode. The controller will remain in the sleep mode untilthe alarm reset feature is activated. The alarm reset feature can be performed by applyinga momentary short across terminals 21 and 22 on the Terminal Block. The user may alsoreset the alarm from the Laptop, Display, Scada, and Handheld.PM CPTransfer Sw itchJ2 -1L o a d co n n e cte d toN o rm a lJ2 -3J2 -2PM CPTransfer Sw itchJ2 -1L o a d co n n e cte d toE m e rg e n cyJ2 -3J2 -2Figure 210

Thestate of the breakers is unchanged. The user must activate the Alarm Reset buttonon the front of the cabinet door to clear the Alarm Feature and restore automaticoperation.Note: Once the PMCP Controller has activated the Alarm Feature, itimmediately goes into an idle state (sleep mode) and remains in this stateuntil the Alarm Reset button is activated.2.0If a current fault should occur from any breaker, the PMCP Controller shallactivate the Alarm Feature which also activates the Feature 86. The PMCP shallshutdown any further automatic operation immediately and the Feature 86 shallinhibit all breakers from being closed electrically from the circuit breaker controlswitches. The user must activate the Alarm Reset button on the front of thecabinet door to clear the Alarm Feature, reset the Feature 86, and restoreautomatic operation.Note: Feature 86 places a normally closed contact in the closing circuit of eachbreaker. Once a current fault has occurred and the Feature 86 is activated,the normally closed contact opens which prevents the breakers from beingclosed electrically from the circuit breaker control switches. Feature 86,once activated, is latched and remains in this state until the Alarm Resetbutton is activated.3.0As part of the ETC safety features, ONLY two breakers are allowed be closed atany given time. The control logic and external hardware shall prevent all threebreakers from being closed at the same time. This safety feature is only availablewhen performing an OPEN Transition transfer.4.0The ETC controls provide a Feature 43M: Automatic or Manual mode operation.When the Automatic Mode is selected, the PMCP Controller operates the MTMscheme normally. While in the Automatic Mode, the breakers can not be operatedfrom the circuit breaker control switches located on the front of the cabinet door.When the Manual Mode is selected, the PMCP Controller shall shutdownautomatic operation. The breakers can now be operated from the circuit breakercontrol switches on the front door.23

If both mains are closed, the PMCP will notsignal to close the Tie.6.0Tie Recovery: When both Mains are closed, the Tie is inhibited from closing bythe controller. If the Tie should close from some other means, the controller shallre-open the Tie immediately.7.0Overlap Recovery: During a non-interruption of power (Closed Transition) onretransfer, all three breakers are closed for about 150 msec until the PMCPController signals for the Tie to open. If the Tie fails to open, the controller shallre-open the last Main that closed. The controller shall activate the Alarm Featureand end automatic operation.24

Only 2 ETC products are required to operate this transferscheme: the PMCP Controller and the Breaker Add-On Panel: Refer to Diagram 1 onthe previous page.Definitions: Normal state S1 and S2 are available, both Mains are closed and TIE openedS1 Source #1S2 Source #2M1 S1 feeder breakerM2 S2 feeder breakerPMCP Controller: ETC controller operating and monitoring a MTM transferAP Breaker Add-On PanelBreaker Add-On Panel PCB containing control relaysManual Re-transfer feature: inhibit re-closing Mains until feature is deactivatedAuto Manual Mode operation: no breaker operation when Manual Mode isselectedTest 1 feature: activated to simulate a S1 failureTest 2 feature: activated to simulate a S2 failureOPEN transfer: load power is interrupted during retransferCLOSED transfer: NO interruption of load power during retransfer86 Fault Lockout Relay: prevent closure of breakers after an overload fault oralarm43M Manual Mode selected: controller is disabled and breakers can be operatedfrom the circuit breaker control switches mounted on the front door.83 Control Voltage Select: if S1 is present then S1 shall power the controlvoltage.

If S1 should restorebefore the delay has expired, the state of the breakers shall remainunchanged. If the delay expires and S1 is unacceptable then M1 opens andTIE closes.1.2S2 powers all the selected load(s)S1 Returns:Selected for Open Transfer:2.1If the controller is selected for OPEN transfer and S1 restores, a retransferdelay shall start. If S1 should fail again before the delay has expired, thestate of the breakers shall remain unchanged. If the delay expires and S1 isacceptable and the Manual re-transfer feature is de-activated then the TIEopens and M1 re-closes. The MTM is restored to the normal state.If the Manual Re-transfer feature is activated, the controller will not returnthe MTM to the normal state until this feature is de-activated.Selected for Closed Transfer:2.2If controller is selected for CLOSED transfer, the PMCP controller sensesboth S1 and S2 sources for proper synchronization before retransferringback to the normal state. Once both sources have meet the synchronizationrequirements (5% voltage difference, 0.2 HZ frequency difference, andwithin 5 electrical
