A-2
[Design Precautions]
WARNING
Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the programmable
controller. Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and
protective interlock circuit for forward/reverse operation or upper/lower limit positioning.
(2) The programmable controller stops its operation upon detection of the following status, and the
output status of the system will be as shown below.
All outputs may turn on when an error occurs in the part, such as I/O control part, where the CPU
module cannot detect any error. To ensure safety operation in such a case, provide a safety
mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit
example, refer to LOADING AND INSTALLATION in this manual.
(3) Outputs may remain on or off due to a failure of an output module relay or transistor. Configure
an external circuit for monitoring output signals that could cause a serious accident.
Status
Overcurrent or overvoltage protection of
the power supply module is activated.
The CPU module detects an error such as
a watchdog timer error by the
self-diagnostic function.
All outputs are turned off All outputs are turned off
All outputs are turned off
All outputs are held or
turned off according to the
parameter setting.
Q series module AnS/A series module

A-3
[Design Precautions]
WARNING
In an output module, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
Configure a circuit so that the programmable controller is turned on first and then the external power
supply.
If the external power supply is turned on first, an accident may occur due to an incorrect output or
malfunction.
For the operating status of each station after a communication failure, refer to relevant manuals for
the network.
Incorrect output or malfunction due to a communication failure may result in an accident.
When changing data of the running programmable controller from a peripheral connected to the
CPU module or from a personal computer connected to an intelligent function module, configure an
interlock circuit in the sequence program to ensure that the entire system will always operate safely.
For program modification and operating status change, read relevant manuals carefully and ensure
the safety before operation.
Especially, in the case of a control from an external device to a remote programmable controller,
immediate action cannot be taken for a problem on the programmable controller due to a
communication failure.
To prevent this, configure an interlock circuit in the sequence program, and determine corrective
actions to be taken between the external device and CPU module in case of a communication
failure.
CAUTION
Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm (3.94 inches) or more between them.
Failure to do so may result in malfunction due to noise.
When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a
large current (approximately ten times greater than normal) may flow when the output is turned from
off to on.
Take measures such as replacing the module with one having a sufficient current rating.

A-4
