IM 33Q06C20-01E

A1. Control Station OverviewIn the standard configuration, the main components of the PFCS/SFCS are two I/Omodule nests containing I/O modules for conversion of signals to and from the field.By adding an I/O expansion rack, a PFCS/SFCS can contain a total of five I/O modulenests.

There are two types of LFCS2/LFCS: the model installed in a cabinet and a rackmountable model. An LFCS2/LFCS is composed of nodes, I/O units, and the RIObus.

There are two types of KFCS2/KFCS: the model installed in a cabinet and a rackmountable model. An KFCS2/KFCS is composed of “Local Nodes”, “RemoteNodes”, and the ESB bus (Extended SB bus).

FFCS may be configured as a compact type field control unit with 3 I/O nodes.

A3.1.2 Installation of Rack Mountable DeviceThis section describes how to install a PFCS/SFCS and a rack mountable LFCS2/LFCS, KFCS2/KFCS, FFCS on a rack or in an instrument panel, its precautions, andhow to install the I/O expansion rack.

WARNING

A rack mountable LFCS2/LFCS, KFCS2/KFCS, FFCS weighs nearly 25 kg, a PFCS/SFCSwith two I/O module nests weights nearly 18 kg. An I/O expansion rack with 3 module nestsweights nearly 8 kg. A sufficient work space for installation should be ensured and theequipment should be installed by several persons with attention to safety.

Observe the following when you install a rack mountable device on a rack or an instrumentpanel.

● Isolation from the Rack

Isolate the rack mountable FCS from the rack by attaching isolation bushings. Fasten a pairof isolation bushings together to each of the screw holes on the plate or the bracket on theFCS to prevent the FCS from touching the rack. And then screw the FCS to the rack. Afterscrewing the FCS to the rack, confirm that the FCS is electrically isolated. Isolation bush-ings are supplied with the rack mountable FCS.

WARNING

When you install the ‘FCS with isolation bushings attached’ on a rack or an instrumentpanel, do not keep the FCS hung on loose screws in an unstable status. Too much forcemay apply to the isolation bushings and cause damaged or broken isolation bushings.


IM 33Q06C20-01E

● Installation Procedure

1. Fasten a pair of isolation bushings together to each of the screw holes on the plate orthe bracket on the FCS. The tapering end of the isolation bushings must come to thefront side where a screw enters.

■ Attaching the Clamp Filters (Ferrite Cores) : LFCS2/LFCS £

IMPORTANT

The clamp filter case is made of plastic, and so may crack when opened and closed at asub-zero temperature (in centigrade) or when a mechanical shock is given, such as if itfalls.

Be careful to follow the working and storage temperature limits (of an HIS and LFCS2/LFCS).

After completing the V net cable (10BASE-5 cable) connection, attach the clamp filters (thatcome with the product) to the V net cables over the cable sheath in order to improve thenoise isolation.

● Clamp Filter Set : LFCS2/LFCS £

6 ferrite cores (part No. A1179MN) per V net cable

TIP

Since terminals 4-6 are in the lower back beneath terminals 1-3 on an RIO bus connector unit, it is easierto connect the wires to terminals 4-6 before terminals 1-3.

An RIO bus cable from an LFCS2/LFCS or another node, or an RIO bus cable to be connected to thenext node can be connected to either terminals 1-3 or 4-6, in principle. However, on the connector unit atwhich the bus connection ends, it is recommended to connect the RIO bus cable to terminals 4-6 andinstall a terminator over terminals 1 and 2. This makes it easier to wire a node that is added later.

A4.5 Connecting a Cable to Contact OutputThis section describes how to connect a cable to contact output of PFCS/SFCS ,LFCS2/LFCS, KFCS2/KFCS and FFCS.

CAUTION

• All equipment connected to a contact output, including the signal wires, junctionterminals, relays, and power supply unit, should comply with CSA 1010 or CSA 950(for a 100-120 V AC power supply), or EN 61010-1 (for a 220-240 V AC power sup-ply).

• When performing wiring for the READY output terminals, attach the clamp filter (partNo. A1193MN, included in accessories) near the terminals. The clamp filter is suppliedwith CE Mark-certified LFCS2/LFCS and KFCS2/KFCS of both rack mountable typesand cabinet types.

• The cable connected to the READY (processor status contact output) terminalsshould run at least 1 cm from other signal cables since a high voltage is applied to it.

Each field control station (an PFCS/SFCS, LFCS2/LFCS, KFCS2/KFCS and FFCS) moni-tors its own processor status. Upon detection of a failure, it outputs a system alarm andopens the output contact. This break (normally closed) contact is labeled as READY, and isopened in the following cases:

• When the CPU stops control.

• Duplexed CPUs, when both CPUs stop control.

• When the power supply fails.

• Duplexed power supplies, when both power supplies fail.

Make sure of the following when using the contact output:

• Avoid applying an AC voltage directly to the contact output terminal. Use a voltage lessthan the rated.

• When this contact directly drives an external relay or the like, use a spark killer toprotect the relay contact.

• RDY:The green light turns on if both the hardware and software are normal. If either of themis abnormal, the light turns off.

• CTRL:In the duplex PFCS/SFCS, the green light turns on if the processor card is the controlside and turns off if it is the standby side. When starting up the duplex PFCS/SFCS,the right side becomes the control side. In the single PFCS/SFCS, the green light isalways on.

• COPY:In the duplex PFCS/SFCS, the green light turns on when program copy is executedand turns off when program copy is completed.When a processor card has been replaced or when the unit is stopped then startedagain, the standby side processor card automatically copies the program of thecontrol side processor card. When copy is completed, the light turns off.In the single PFCS/SFCS, the light is always off.

• START/STOP:This maintenance switch is used for forcing stop or restarting the processor card CPU.If this switch is pressed when the processor card is still operating, the CPU will stop.If this switch is pressed when the processor card is not operating, the CPU will restart.This switch is located inside a hole next to the START/STOP sign.Push the switch using a slender bar of around 2 mm in diameter.

• Daily inspections

• Procedures for replacing parts having a limited life that must be replaced, andparts that can be replaced by the user

• Procedure for replacing each unit

CAUTION

• If dust or dirt is found in peripheral devices, clean with a vacuum cleaner or dry softcloth. If the stain is tough and cannot be removed easily, wipe with soft cloth soaked inwater or mild soap water after wringing it tightly.

• When power is ON, do not install or remove the cards, cables, connectors not listed inthis manual.

• During maintenance, put up wrist strap, and take other ESD (Electrostatic Discharge)measures.

• Opening a cabinet door during operation increases the radiation noise; immunityagainst the radiation noise cannot be guaranteed.

A7.1 Precautions for MaintenanceThis section describes the general precautions for maintaining the FCS hardware.



IM 33Q06C20-01E

A7.1.1 Precautions for Static ElectricityNote the following to prevent faults due to static electricity:

• When storing or carrying a maintenance part, put it in an anti-static bag. (Such partsare packed in anti-static bags with a label describing precautions for static electricity,when delivered.)

• During maintenance, wear a wrist strap with grounding wire and ground the wire via a1 M ohm resistor.

• When placing a card with a built-in battery (power supply unit) on a conductive sheet,set the battery switch to OFF or remove the battery.

• When carrying out maintenance at a desk; 1) do it on a conductive sheet that isgrounded via a 1 M ohm resistor, 2) wear a wrist strap, and 3) keep away things whichmay be charged, such as plastic.

• Do not touch maintenance parts without first putting on a wrist strap and placing theparts on a conductive sheet.

• The wrist strap and conductive sheet are available from Yokogawa’s sales agents.

Figure Power Supply Wiring for ACB21/ACB41 £



● Connections £

Lead the power supply cable into the cabinet through a round hole of a seven-piece bottomplate; the power supply input terminals on the power distribution board are directly abovethe hole. This is the same for dual-line power supplies.

CAUTION

• Wire the power cable through the conduit at the desk entrance for the following rea-sons:

• To prevent damage to the cable due to contact with a metal plate.

• To avoid applying excessive weight on the solderless lugs or power connectionterminals due to the weight of the cable.

• Turn off the main power supply, and perform work after confirming with a tester thatthere is no power in the power cable to be connected.

• After the power cable has been connected, turn on the power to the power cable withthe breaker in the power panel turned OFF. Then, confirm with a tester that normalpower is being supplied to the power connection terminal.

• Wire the power cable so that a distance of 1 cm or more is maintained from othersignal lines.

1. For the power cable, an 8 mm2 cable or thicker is recommended.

2. Provide terminal treatment for the end of the cable, and crimp a ring-tongue crimp-onlug (for an M6 screw) onto each wire.

3. Detach the protection cover for the terminal strip TM1 on the power distribution board.

4. Connect the non-grounded side of the power supply wires to terminal L, and thegrounded side to N.

5. After connecting the power cable, turn on the power supply to the cabinet while leav-ing the circuit breaker on the power distribution board OFF. Then, use a circuit tester tocheck that the power is supplied at the power supply terminals.

6. Replace the protection cover.

This completes the power supply wiring.


IM 33Q06C20-01E

■ Connecting the Grounding Cable to ACB21/ACB41Be sure to ground the equipment in order to avoid the electric shock of the operator andmaintenance engineers and to prevent the influence of external noise.

The grounding bar is shown on the page before the preceding one.

CAUTION

When grounding the cabinet, connect the grounding cable to the designated protectivegrounding terminal.

1. The grounding resistance must be 100 ohm or less. Do not share the grounding withequipment of other systems.

2. For the grounding bus, use a 22 mm2 cable or thicker.

3. The grounding bar for connecting grounding wires is at the bottom front of the cabinetand is not isolated from the cabinet casing.

■ Wiring for Contact Outputs of ACB41This section describes the wiring between the contact outputs of ACB41 and the house-keeping unit (hereinafter referred to as HKU). The terminal board of the contact outputs isplaced at the lower part of the cabinet. The diagnosis signals of the internal temperature ofthe cabinet and the fans are sent to the CPU though the HKU and the connected FIOmodules. To enable the housekeeping capability, the corresponding software application isrequired.

CAUTION

• All equipment connected to a contact output, including the signal wires, junctionterminals, relays, and power supply unit, should comply with CSA1010 or CSA950 (fora 100-120 V AC power supply), or EN61010-1 (for a 220-240 V AC power supply).

• When performing wiring for the READY output terminals, attach the clamp filter (partNo. A1193MN, included in accessories) near the terminals.

• The cable connected to the READY (processor status contact output) terminals shouldrun at least 1 cm from other signal cables since a high voltage is applied to it.

The figure below shows the terminal board of the contact outputs and HKU.

● Contact Output Wiring £

Make sure of the following when using the contact output:

• Avoid applying an AC voltage directly to the contact output terminal. Use a voltageless than the rated.

• When this contact directly drives an external relay or the like, use a spark killer toprotect the relay contact.

The figures below show the contact output terminals of an ACB41 cabinet and an exampleof using a spark killer.
