I10 capacity is 120 points max. per unit, but 240 110s can be covered by linkage operation.
Now the F2 series
is enhanced greatly with additional specializedfeatures and functions.
The outlinesare as follows, but accordingly peripherals need to be updated.
However, when
it is usedwithin conventionalF2 functions, peripherals need not be updated.
@ The programcapacity is enhancedup to 2000 steps. (Except F2-20M)
And inaddition to EPROM cassette, EEPROMcassette can be read and written.
@ Pointsof state for Step-ladderare enhanced from 40 to 168 points.
@ 64 points of data register (BCD 3 digit) are added.
@) Functional instructionsare highly enhanced. (Includingarithmetic handling)
@ Special functionunitscan be handled.
*Only CPU card in the base unit
is enhanced, so dimensionsand Input/Output card are the same as

POWER SUPPLY
Power supply voltage. . . . . . . 24VDCk8V

2-1-1 Power Supply
(1) Connect a power supply cable of the correct rating to the base unit and extension unit (if used)
as illustrated. Supply voltages should be as specified.
It is recommended to provide power
supply switch which can be used when the ROM cassette
is plugged inor off.
(2) The power consumptionof the base unit
is less than 20VA to F2-20, 25VA to F2-40and 40VA
to F2-60however, this does not include the power consumption of any external load.
(3) The power must be switched offwhen the ROM cassette is loaded onthe base unit or unloaded
from the unit.
(4) The power supply to the extension (if used)shall be connected to same ONIOFF switch for the
base unit.
2-1-2 Emergency Stop
Although the PC is designed to switch off all its outputs in emergencies, external safety power
switching equipment should be incorporated also.
2-2 GROUNDING
(1) The unit must be grounded as illustrated. The extension unit (if used) must also be grounded
with same line of base unit.
(2) Resistanceshould be less than loon.
(3) Grounding must not be shared with any high power equipment such as a motor system.
2-3 RUNISTOP MODE TERMINALS
(1) These terminals should be connected to key switches or other suitable control devices (push
button)as illustrated.
(2) The RUN mode is used when the programmable controller is running aprogram (controlling
a
system).
(3) When the STOP mode is used (or there is a power failure of more than 20msec.), all outputs
are turned off and timers, plus the 128 of 192 auxiliary relays are reset. However, all counters
and 64 of the auxiliary relays, state relays and some special auxiliary relays are maintained by
battery support.
(4) When the 'STOP' switch is on, all outputs will be 'OFF'. However it is recommended that
external facilities be provided in case of emergenciesto support and back up this facility.
(5) Inthe case of AC input models, see section
3-5.
If RUN terminal is kept ON by permanent wiring, normally, PC will not leave RUN mode.
However, if power
is removed and a programming panel is connected in program mode, on
returnof power, PC will enter program mode and allow alterations to be made tothe program.
2-4 RUN OUTPUT TERMINALS
( Lz-a or U (except F2-20M)
(1
) A relay contact is provided between these two terminals inside. The contact is switched on at
normal run mode, but is switched off if CPU error might be caused from electrical noise Inter-
ference, etc Itis switched off in STOP mode.
(2) This facility is used to make an emergency stop circuit
or warning circuit.
(3) Output load of the relay is less than 35VA. For loads over the rated limit,operation should be
performed through an extra relay.

2-5 DC24V TERMINALS
(1 ) In the case of the sink input (minuscommon)models, input devices of non-voltagecontacts are
powered from input terminals and the
24+ terminals provide DC24V power for input sensor
devices such as proximity switches or photo sensors.
(2) In the case of the source input (pluscommon) models, non-voltagecontact devices are powered
from the
24V terminals and the 24V terminals have extra power capacityfor the input sensor
devices
as specified.
(3) Ifthe extension unit is used, connect the DC24V terminals betweenthe base unit and extension
unit. The
COM terminals are also connected in the same manner.
(4) Any external power must not be supplied to these terminals.

) Connect input control devices, e.g. limit switches, push buttons, to the input terminations as
specified.
(2) In the case of sink input (minus common) models, non-voltage contact devices are powered
from the input terminals and the 24Vterminal pointscan be used to power external transistors
such
as proximity switches.
The capacity of 24V DC source
is rated by 0.1 Amp (F2-20140)and 0.2 Amp (F2-60)from
24V terminal inaddition to each 7mA from all input terminals.
(3) In the case of source input (plus common) models, non-voltage contact devices are powered
from the 24V terminals and the current rating at each input terminal
is 24VDC, 6mA. The
control devices should be specified accordingly.
The 24V terminal points can also be used to power external transistors such
as proximity
switches.
Total of 0.1 Amp (F2-20140)and 0.2 Amp (F2-60)current by two 24V terminalscan be used
for such transistors in addition to each 6mA supply to all input terminals.
Iffurther more power is requested, use an external power source of 16to 36V DC.
The OV terminals are used for negativesof this DC source.
(4) If transistor circuits,such as proximity switches, are connectedto inpuf terminals,their parallel
resistance should be morethan 100kQand their series resistance less than Ikn.
(5) Three common terminals are connected internally and are common. However, the base and
extension unit commons are not linked unless connected together externally as detailed in
other section section 2-5.
The commonterminal is also used for
a negativeof 24V DC source.
(6) For the sake of convenience and appearance and to avoid damage or failure, input wires should
be bound or cabled together.
It is recommendedthat input wires are not longer than 20 metersfor the general use. However,
the length can be longer but it depends upon the conditions of the noise environment and
voltage drop.

(Example: Fz-40MR-UAi )
When input devices such as proximity switches or photo sensors are connected to the input
terminals, be aware that the leakage current may activate the input signal incorrectly.
Where the leakage current
is more than 2mA, it may prove necessary to provide additional
bleeder resistor or CR circuit
(e.g. O.1pF + IOOQ), otherwise use input deviceswith low leakage
current of less than 2mA.
The power supply to the PC can use 110/220VAC, however, AC input voltage of 11OVAC or
220VAC is different accordingto the model name.
When AC input type PC and DC input type PC are mixed, (e.g. base unit and extension unit),
commonterminalsof inputsmust
not be connected together.

Normal open relay contacts are connected internally to the output terminals on the base and
extension units. The ratings of the contacts are 2A at 24V DC, 110/120V AC, 220/240V AC.
These ratings apply for resistiveloads (COS
Q = 1.0).
The durability data of output relays
is stated inanother section (4-5).
Each internal contact is protected by a residual current circuit. When the contact is closed, its
current leakage will normally be less than I .lmA at 220V AC or 0.55mA at 110V AC.
However, it
is possible that this might have some effect on external loads.
Where the external current demand
is very low, it may prove necessary to provide additional
parallel resistance because of the influenceof leakage (see section 4-5).
When using the controller in a direct current circuit, it is recommendedto connect afree wheel
diode in parallelto the inductive load.

Connect external load devices e.g. contactors, pilot lamps, solenoid (electromagnetic) valves, etc.,
tooutput terminations of the base unit and extension unit (if used).
As shown inthe lastfigure, common terminals are providedfor the output terminations.
As these commons are not linked and cover each four output terminals intheir block, different
types of power can be used as shown in the above example as far as the output terminals are in
a block share of one type of power.
The load limitation of the triac (SSR) outputs is 1A for each individual output, but the total
collective output load should not exceed 8A across all 16 outputs at AC 110/120V or AC 2201
240V.
For inductive loads, the rated coil of magnetic contactors should be within 50VA at AC 110/
120V or 100VA at AC 220/240V. If the coil load
is over these limits, then an external relay will
be required. For lamp loads above IOOW, an external relay will also be required.
Each triac (SSR) inside the unit will withstand moderate surge currents, and is protected by a
residual current circuit. With the triac 'off' current leakage is less than 1.2mA at AC 120V or
2.2mA at AC 220V. However, it
is possible that this might have some effect on external loads.
It is not possible to operatetriac output card on DC loads.
4-3 TRANSISTOR OUTPUT MODELS (F2-20/40/60UT.-u) SINK OUTPUT TYPE

Connect external load devicese.g. contactors, pilot lamps, solenoid (electromagnetic) valves, etc.,
to output terminations of the base unit and extension unit.
The load limitation of the transistor outputs
is 1 A for each individual output, but the collective
output load should not exceed
2A per 4 points at DC 24V.
Due to surge current limitations lamp loads should be within 3W.
When other loads are connected to an output termination in addition to lamp load, the total
output load tothis termination should be as specified with referenceto the following table.
The external DC power supply should be DC 24V +15%/-30%.
2A rated back-up fuses or protectors are recommended per each four outputs to prevent damage
to the circuit boardsof the PC inthe event of ashort circuit fault in one of the external circuits.
