z Always ground the FG and LG terminals to the protective ground conductor.

Failure to do so may cause an electric shock or malfunctions.

z Wire the module correctly after confirming the rated voltage and terminal layout.

Connecting a power supply of a different voltage rating or incorrect wiring may cause a fire or failure.

z Do not connect multiple power supply modules to one module in parallel. The power supply modules may be heated, resulting in a fire or failure.

z Press, crimp or properly solder the connector for external connection with the specified tool.

Incomplete connection may cause a short circuit, fire or malfunctions.

z Tighten terminal screws within the specified torque range. If the screw is too loose, it may cause a short circuit, fire or malfunctions.

If too tight, it may damage the screw and/or the module, resulting in a short circuit or malfunctions.

z Carefully prevent foreign matter such as dust or wire chips from entering the module.

Failure to do so may cause a fire, failure or malfunctions.

z Install our programmable controller in a control panel for use.

Wire the main power supply to the power supply module installed in a control panel through a distribution terminal block.

Furthermore, the wiring and replacement of a power supply module have to be performed by a maintenance worker who acquainted with shock

protection. (For the wiring methods, refer to Type A1SCPUC24-R2/

(c) When a power transformer or insulating transformer is employed to reduce the voltage from 200 VAC to 100 VAC, use one with a capacity greater than those indicated in the following table.

Power Supply Module Transformer Capacity

A1S61PN 110VA n

A1S62PN 110VA n

n: Stands for the number of power supply modules.

(d) Separate the programmable controller’s power supply line from the lines for I/O devices and power devices as shown below.

When there is much noise, connect an insulation transformer.

(e) Taking rated current or inrush current into consideration when wiring the power supply, be sure to connect a breaker or an external fuse that have proper blown and detection.

When using a single programmable controller, a 10A breaker or an external fuse are recommended for wiring protection.

(f) Note on using the 24 VDC output of the A1S62PN power supply module.

CAUTION z Do not connect multiple power supply modules to one module in parallel. The power supply modules may be heated, resulting in a fire or failure.

If the 24 VDC output capacity is insufficient for one power supply module, supply 24 VDC from the external 24 VDC power supply as shown below:

(g) 100 VAC, 200 VAC and 24 VDC wires should be twisted as dense as possible. Connect the modules with the shortest distance.

Also, to reduce the voltage drop to the minimum, use the thickest wires possible (maximum 2mm

).

(h) Do not bind 100VAC and 24VDC wires together with main circuit (high tension and large current) wires or I/O signal lines (including common line) nor place them near each other. Provide 100mm (3.94 inch) clearance between the wires if possible.

(i) As a countermeasure to power surge due to lightening, connect a surge absorber for lightening as shown below.

Surge absorber for lightening Programmable

controller I/O devices

E1 E1

POINT

(1) Separate the ground of the surge absorber for lightening (E1) from that of the programmable controller (E2).

(2) Select a surge absorber for lightening whose power supply voltage

does no exceed the maximum allowable circuit voltage even at the time

of maximum power supply voltage elevation.

(2) Wiring to I/O device

(a) The solderless terminal with insulation sleeve is inapplicable to a terminal block.

It is advisable to cover the wire connection part of a terminal with a mark tube or insulation tube.

(b) Install wiring to a terminal block using the cable of core diameter 0.3 to 0.75mm

, and outside diameter 2.8mm or less.

(c) Run the I/O line and output line away from each other.

(d) When the main circuit line and power line cannot be separated, use a shielding cable and ground it on the programmable controller side.

However, ground it on the opposite side in some cases.

Shielded cable

Shield jacket RA

(e) When cables are run through pipes, securely ground the pipes.

(f) Run the 24VDC input line away from the 100VAC and 200 VAC lines.

(g) The cabling of 200m (656.2ft.) or longer distance may produce

leakage current depending on the capacity between lines and result in an accident.

(h) As a countermeasure against the power surge due to lightning,

separate the AC wiring and DC wiring and connect a surge absorber for lightning as shown in (i) of item (1).

Failure to do so increases the risk of I/O device failure due to lightning.

(3) Grounding

CAUTION z Be sure to ground the FG terminals and LG terminals to the protective ground conductor. Not doing so could result in electric shock or erroneous operation.

(a) Carry out the independent grounding if possible. (Grounding resistance 100 or less.)

(b) If the independent grounding is impossible, carry out the shared grounding (2) as shown below.

(c) Use the cable of 2mm

or more for grounding.

Set the grounding point closer to the programmable controller to make the grounding cable short as possible.

(d) If a malfunction occurs due to earthling, separate either LG or FG of

the base module, the device combination, or all the connection from

the earthling.

POINT

(1) Use the thickest possible (max. 2 mm

(14 AWG)) wires for the 100/200 VAC and 24 VDC power cables. Be sure to twist these wires starting at the connection terminals. For wiring a terminal block, be sure to use a solderless terminal. To prevent short-circuit due to loosening screws, use the solderless terminals with insulation sleeves of 0.8 mm (0.03 inch) or less thick. The number of the solderless terminals to be connected for one terminal block are limited to 2.

Terminal block Solderless terminals

with insulation sleeves

(2) Be sure to ground the LG and FG terminals. Failure to do so may cause the programmable controller to be susceptible to noise. Note that LG terminals include the potential as half as that of input voltage; you might get an electric shock when you touch them.

(3) A1S61PN and A1S62PN do not need to be switched as the are 100 to

240VAC wide-range.

4.4 Precautions when Connecting the Uninterruptible Power Supply (UPS) Connect the programmable controller system to the uninterruptible power supply (UPS), while paying attention to the followings.

Use the on-line UPS or line interactive UPS (voltage distortion of 5% or less.)

Alternatively, use the off-line UPS, i.e., FREQUPS-F series with serial number P or later (Mitsubishi).

Example: FW-F10-03.K/0.5K

Do not use the off-line UPS other than above.

*1 The fuse in the output module is provided to prevent the external wiring from burning in the event of a short circuit in the module’s output. Consequently, it may not be able to protect output devices.

If an output device is damaged in a failure mode other than a short circuit, the fuse might not be blown.

*2 The "ERR." LED will alxo come ON when the external power supply is cut.

*4 The power supply voltage (12/24VDC) is applied in the LED’s reverse direction.

If the peak inverse voltage is insufficient, connect protective diodes in series with each of the LEDs.

6. When an error occurs while in the PLC RUN or RUN state, the self-diagnostic function stores an error indication or error code (including step number) in the special register. This section describes how to read the error code, as well as causes of errors and corrective actions. Table 6.1 shows the error codes for A1SCPUC24-R2, Table 6.2 the error codes and detailed error codes for

A1SHCPU and A2SHCPU (S1), and Table 6.3 the error codes and detailed error codes for A2ASCPU(S1/S30) and A2USHCPU-S1, respectively. Take proper action to eliminate the cause of error.

(1)EP-ROM or memory cas-sette, which cannot be decoded, has been loaded.

(2)Since the memory contents have changed for some reason, instruction code, which cannot be decoded, has been included.

(1)Read the error step by use of a peripheral equipment and correct the program at that step.

(2)In the case of EP-ROM or memory cassette, rewrite the contents or replace with an EP-ROM or memory cassette which stores cor-rect contents.

"PARAMETER ERROR"

(Checked at power-on,

STOP RUN, and PAUSE

RUN)

11 Stop (1)Capacity larger than the memory capacity of CPU module has been set with the peripheral equipment and then write to CPU mod-ule has been performed.

(2)The contents of parameters of CPU memory have changed due to noise or the improper loading of memory.

(3)RAM is not loaded to the A1 or A1NCPU.

(1)Check the memory capac-ity of CPU with the memory capacity set by peripheral equipment and re-set incor-rect area.

(2)Check the loading of CPU memory and load it cor-rectly. Read the parameter contents of CPU memory, check and correct the con-tents, and write them to CPU again.

(3)Install the RAM and write parameter contents from a peripheral device.

"MISSING END INS."
