FT80 Reduced Voltage - Wye Delta (Star-Delta) Closed

The Automatic Transfer Switch Option may be

added to any FD type Fire Pump Controller

whenever automatic transfer from normal to

alternate power is required.

The automatic Transfer Switch and Fire Pump

Controller are mounted in the same enclosure

or in separate enclosures to form one unit and

interwired - depending on the horsepower and

voltage required.

LED Status Indication

An engine test button is provided on the ATC-

300 controller that can be used to test the

Source 2 (generator) engine. The operator can

select the engine run test time (0-600 minutes).

As well, a silence pushbutton is provided which

de-energizes the alarm bell.

The FT Series transfer switch operating mecha-

nisms are mechanically interlocked to prevent

the normal and alternate source from connect-

ing at the same time.

The switch operates upon signals received from

the ATC-300 Plus controller.

The panel mounted,

multi-function, micropro-

cessor based ATC-300

Plus controller accurately

monitors two power

sources and provides the

necessary intelligence

to reliably operate the

transfer switch through

a series of programmed

sensing and timing func-

tions.

The ATC-300 Plus controller membrane is

equipped with seven keypad input buttons

which are used to program the controller as well

as set operating parameters.

Five LED’s indicate the status of the power

sources.

Source 1 Available Source 1 Connected

Source 2 Available Source 2 Connected

Unit Status

The FT Series Transfer Switches

will perform an automatic

transfer from Normal to Alter-

nate source when the Voltage

drops to 85% of normal, or

there is a loss of any phase

and/or Phase Reversal.

The ATC-300 Plus continuously monitors the

normal source for out of range setpoint values.

When the source is outside the dropout set-

points, the source will become unavailable.

This prompts a transfer to the alternate source.

Retransfer occurs when the normal source’s

frequency and/or voltage return within pickup

setpoints.

The alarm relay is de-energized to indicate an

absence of an alarm state and energized to

indicate the presence of an alarm condition.

Alarm conditions include:

Improper Circuit Breaker Operation

Motor Operator Failure

Lockout

Failsafe Condition

Aborted Engine Test

Aborted Plant Exerciser

Unsuccessful in-phase Transition

The FT80 Transfer Switch Controllers use a

method of connecting the pump motor windings

into wye conﬁ guration to start, then switching to

a delta conﬁ guration to run.

This reduces the starting current of the motor

signiﬁ cantly.

Wye-Delta starting is the only method that has

a starting torque efﬁ ciency of 100%. The FT80

can be programmed for either fully automatic or

semi-automatic operations.

Communication

The controller can be ordered with the option to

display and output current values and status,

on command, from various software protocols

through the appropriate port(s).

Embedded Web Page

The web page is a multifunction tool that allows

the user to view the controller’s current status,

data values, programmed set points and history.

It is accessed using the optional ethernet port.

USB Port / USB Drive

The logic controller board is equipped with a

USB port that can be used to transfer data to

and from a portable USB Drive device (memory

stick).

Ethernet Port

An optional ethernet port is used for direct con-

nection to a computer for data transfer.

RS485 Serial Port

An optional RS485 serial port can be provided

for communication to various external software

programs.

Buzzer

A buzzer is mounted on the logic board which

will operate if Fail to Start, Hardware Malfunc-

tion or any Common Alarm condition exists.

Transformers

Incoming line voltage is run directly to the I/O

board from the incoming lines. The three trans-

formers mounted on the I/O board will accept

voltage inputs between 100 and 600V.

Customer Connection Terminals

Connection terminals for external customer

connections, are located on the top of the

Power I/O board.

Output Relays

Seven socket mount,

8 Amp, 2 Form - C

(DPDT) output relays

are provided standard

on each power I/O board.

They are designated for:

Common Alarm,

Phase Failure,

Phase Reversal,

Pump Run,

Startup,

Acceleration

and Future # 1.

Each socket has an LED mounted on the I/O

board which indicates each relay’s coil status.

Optional Output Relay Boards

There is provision to add up to eight additional

relay outputs, via optional relay output boards.

Each board contains a maximum of 2 addi-

tional relays. The Power I/O Board will accept a

maximum of 4 optional boards which mount in a

snap-on conﬁ guration.

Each board provides an area for the user to

label the terminal number and relay name.
