manual on to the end user.
[DESIGN PRECAUTIONS]
DANGER
zProvide a safety circuit outside the C Controller module to ensure that the
entire system will operate safely even if an external power failure or C
Controller module failure occurs.
Failure to do so could result in accidents due to erroneous output or
operation.
(1) For an emergency stop circuit, protection circuit and interlock circuit that
is designed for incompatible actions such as forward/reverse rotation or
for damage prevention such as the upper/lower limit setting in
positioning, any of them must be provided outside the C Controller
module.
(2) When the C Controller module detects the following conditions, it will
disable the output (Y) from the user program and writing to buffer
memory in the case of both (a) and (b) and turn off all outputs for (b).
Whether to hold or clear all the outputs is set by a parameter.
(a) The overcurrent protector or overvoltage protector of the power
supply module is activated.
(b) An error such as a watchdog timer error is detected by the
self-diagnostic function of the C Controller module.
If an error occurs in I/O control parts and the C Controller module cannot
detect the error, all the outputs may turn ON.
Provide a fail-safe circuit or a preventive mechanism outside the C
Controller module so that machines will operate safely in such a case.
For fail-safe circuit examples, refer to Section 3.2 in this manual.

[DESIGN PRECAUTIONS]
DANGER
(3) Output could be left on or off when there is a fault in an output module
relay or transistor.
So build an external monitoring circuit that will monitor any output signal
that could cause serious accidents.
zIf load current more than the rating or overcurrent due to a short circuit in the
load has flowed in the output module for a long time, it may cause a fire and
smoke. Provide an external safety device such as a fuse.
zCreate the circuit so that the external power supply will turn on after the C
Controller system is powered on.
Turning on the external power supply first could result in accidents due to
erroneous output or operation.
zFor each station's operating status in the event of a each station error, refer
to the corresponding each station manual.
Not doing so could result in erroneous output or operation.
zWhen controlling a running C Controller module (data modification) by
connecting a personal computer to the C Controller module, create an
interlock circuit on user programs so that the whole system functions safely
all the time.
This must be also done when performing any other controls (e.g. operating
status change (status control)) or operations instructed from the computer.
In these controls, especially the one performed from an external device to a
C Controller module in a remote location, some C Controller side problem
may not be resolved immediately due to failure of data communications.
To prevent this, create an interlock circuit on user programs and establish
corrective procedures for communication failure between the external device
and the C Controller module.
zWhen setting up the system, do not allow any empty slot on the base unit.
If any slot is left empty, be sure to use a blank cover (QG60).
Otherwise, in the short circuit test or when an overcurrent or overvoltage is
accidentally applied to the external I/O section, internal parts of the module
may be flied.
CAUTION
zDo not install the control wires or communication cables together with the
main circuit or power wires, or bring them close to each other.
Keep a distance of 100 mm (3.94 inch) or more between them.
Not doing so could result in malfunctions due to noise.
zWhen controlling a lamp, heater or solenoid valve using an output module,
large current (approximately ten times greater than in normal conditions)
may flow when the output is turned ON from OFF.
Take preventive measures such as replacing the module with the one having
sufficient rated current.

3.2 Fail-safe Circuit
DANGER
zProvide a safety circuit outside the C Controller module to
ensure that the entire system will operate safely even if an
external power failure or C Controller module failure
occurs.
Failure to do so could result in accidents due to erroneous
output or operation.
(1) For an emergency stop circuit, protection circuit and
interlock circuit that is designed for incompatible
actions such as forward/reverse rotation or for damage
prevention such as the upper/lower limit setting in
positioning, any of them must be provided outside the C
Controller module.
(2) When the C Controller module detects the following
conditions, it will disable the output (Y) from the user
program and writing to buffer memory in the case of
both (a) and (b) and turn off all outputs for (b).
Whether to hold or clear all the outputs is set by a
parameter.
(a) The overcurrent protector or overvoltage protector
of the power supply module is activated.
(b) An error such as a watchdog timer error is detected
by the self-diagnostic function of the C Controller
module.
If an error occurs in I/O control parts and the C
Controller module cannot detect the error, all the
outputs may turn ON.
Provide a fail-safe circuit or a preventive mechanism
outside the C Controller module so that machines will
operate safely in such a case.
(3) Output could be left on or off when there is a fault in an
output module relay or transistor.
So build an external monitoring circuit that will monitor
any output signal that could cause serious accidents.
zIf load current more than the rating or overcurrent due to a
short circuit in the load has flowed in the output module for
a long time, it may cause a fire and smoke. Provide an
external safety device such as a fuse.
zCreate the circuit so that the external power supply will turn
on after the C Controller system is powered on.
Turning on the external power supply first could result in
accidents due to erroneous output or operation.
zFor each station's operating status in the event of a each
station error, refer to the corresponding each station
manual.
Not doing so could result in erroneous output or operation.

9
DANGER
zWhen controlling a running C Controller module (data
modification) by connecting a personal computer to the C
Controller module, create an interlock circuit on user
programs so that the whole system functions safely all the
time.
This must be also done when performing any other controls
(e.g. operating status change (status control)) or
operations instructed from the computer.
In these controls, especially the one performed from an
external device to a C Controller module in a remote
location, some C Controller side problem may not be
resolved immediately due to failure of data
communications.
To prevent this, create an interlock circuit on user
programs and establish corrective procedures for
communication failure between the external device and the
C Controller module.
CAUTION zDo not install the control wires or communication cables
together with the main circuit or power wires, or bring them
close to each other.
Keep a distance of 100 mm (3.94 inch) or more between
them.
Not doing so could result in malfunctions due to noise.
zWhen controlling a lamp, heater or solenoid valve using an
output module, large current (approximately ten times
greater than in normal conditions) may flow when the
output is turned ON from OFF.
Take preventive measures such as replacing the module
with the one having sufficient rated current.
When the C Controller system is powered ON-OFF, the control output may not be
supplied normally for a little while because of the delay time and rise time
difference between the C Controller system power supply and the external power
supply for the control target (especially in DC).
In the case of a DC output module, for example, when power is applied to the
external power supply first and then the C Controller system power supply, the
DC output module may temporarily generate false output at power-on of the C
Controller system. Therefore, it is necessary to configure a circuit in which power
is applied to the C Controller system first.
Also, erroneous operations may be performed when the external power supply or
C Controller module is faulty.
To prevent the erroneous operations from resulting in entire system failure, and
from a viewpoint of fail-safe system operation, configure circuits outside the C
Controller module for the areas that will lead to mechanical damage and/or
accidents due to erroneous operations (emergency stop circuit, protective circuit,
interlock circuit, etc.)
A system design circuit example based on the above viewpoint is shown on the
next page.

The power-ON procedure is as follows:
For AC
1) Turn ON the power.
2) Set the C Controller module to
"RUN".
3) Turn ON the start switch.
4) When the magnetic contact
(MC) comes ON, the output
equipment is driven by the user
program *1.
For AC/DC
1) Turn ON the power.
2) Set the C Controller module to "RUN".
3) When the DC power is established,
RA2 goes ON.
4) RA2’s ON turns XM ON, and
processing starts in the user program*2
when the DC input signal is established
100%.
5) Turn ON the start switch.
6) When the magnetic contact (MC)
comes ON, the output equipment is
driven by the user program.
