smelling or heating, turn off the power supply and contact
your agent of CHINO Corporation.
■
Request for ensuring against risks
1. Environment
Make sure not to use your controllers in
・places containing corrosive gas (ex. sulfuric gas, etc.),
powder or dust,
・places containing flammable or explosive gas,
・places flooded or covered with oil,
・places subject to significant change of temperature and
strong wind
・places where is significantly influenced by vibration and
shock
・places subject to direct sunlight and dew condensation.
2. Unused terminals
Make sure not to wire to unused terminals.
3. Inductive noise
・Make sure to separate all wirings to your controller from
power line with high voltage or high current.
・Install your controller apart from equipment generating
strong magnetic field, electrical field or high frequency.
4. Ventilation
Make sure not to block the ventilation openings to ensure
the heat dissipating space for your controller.
5. Cleaning
When cleaning is required, make sure not to use
chemicals (ex. thinner, benzene, etc.) affecting molded
parts.
Use alcohol available in markets.
6. Safety measures at final products side
・To ensure safety in the event of malfunction of your
controller, prepare separate safety measures.
・Prepare an enclosure for protection against fire when
installing your controller.
・Prepare safety measures to prevent contact with
terminals.
Caution
Note

1. Installation to a panel
To avoid electrical shock, make sure to turn off the power supply and then install your controller to a
panel.
∙Installation condition
・Thickness of panel: Steel sheet of 1 to 10mm ・ Installation angle: Within 10º for forward tilting and backward tilting, and
within 15º for left and right
① Insert the terminal board side of your controller into the angular hole of the panel cutout. When your controller is with optional
water-proof, mount the rubber packing attached and then insert your controller.
②Insert the fixtures (2 pieces attached) into the mounting holes of your controller (for up and down sides), and then push them
into the panel.
③For the optional water-proof only, tighten the screw of the fixture. [Tightening torque]: 0.5 to 0.7 N･m
Remark：The figures below show Model LT370. For Model LT350, the same installation procedure is required.

2. Before wirings
① To avoid electrical shock, make sure to turn off the power supply and then work all wirings.
②Work all wirings by only personnel who have basic knowledge of wiring and
experienced the actual works.
1. Use a single-phase power supply with less noise, distortion of wave, voltage fluctuation to avoid malfunction of your
controller.
2. If the power supply has noise too much, prepare a noise filter or other measures separately.

4. Troubleshooting/Maintenance
4.1 Troubleshooting
Trouble Check/Cause/Action
①Is the rated power (100 to 240V AC, 24VDC) supplied to the power terminals?
②Is the connection to the power terminals (L, N / +, - ) correctly?
Not operated at all
③Turn off the power supply and then tern it on again. If the operation is normal, CPU may be
malfunctioned by electrical noise. In this case, prepare measures to suppress the noise.
No control output “Run/Ready” may be set at [rEdy]”. Set it to [rUn].
Late transition The set value of “Output variation limiter” may be low. Set it to be higher.
Stable at above to setpoint The control may be P and D only due to low set value of “ARW-H”. Set it to be higher.
Stable at below to setpoint The control may be P and D only due to low set value (minus value) of “ARW-L”. Set it to be
higher.
Control result not stable ①The derivative time may be too short. Set it to be long.
②The derivative time may be too long. Set it to be short.
Control
operation
abnormal
Overshooting Set the “targeted value filter” to ON.
Not stable
1) Are input terminals connected securely? 2) Is the input signal (sensor) stable? 3) Make sure
that a sensor (thermocouple or resistance thermometer) is not connected in parallel to other
instruments.
Measured
value
abnormal Not correct 1) Is the input type correct? 2) Is the “engineering unit” correct? 3) For the thermocouple input, is
a thermocouple or an extension wire connected to the input terminals?
SV stopped on its way The set value of “SV limiter L” or “SV limiter H” may be not correct.
SV rising or falling “SV rising ramp” or “SV falling ramp” has been set. (If it has been set, its ramp operation
functions at the selection of SV No., the change of SV, etc.)
Incorrect
settings
Key not accepted Keys may be locked.

Your controller may be in trouble. Turn off
the power supply and then turn it on again.
If it is still in trouble, contact your agent of
CHINO Corporation.
*1: Control continues without reference junction compensation. *2: Control continues on non-calibration condition.
4.3 Control at power recovery
1) Short power interruption
For the short power interruption within 20msec, the normal operation continues.
2) When recovery
The control operation is determined by the selection in “Control at power recovery” of Mode 5. In case of “ ”, the control
operation before power interruption or power off is continued. In case of “ ”, the control output becomes to the value of
“Preset out”.
■How to check the type

②Press key for several times until “Model confirmation 1”
appears. 3-digit figure (“A” mentioned below) is displayed.
③Press key again to appear “Model confirmation 2” or
“Model confirmation 3”. 3-digit figure of “B” or “C” is displayed.

■Set the parameters in Mode 0 first. The parameters in
Mode 0 exist in Mode 4 and Mode 6.
*1: Refer to the separate instruction manual for
communications interface.
*2: For the details, read [ Heating/cooling control in “9.
Setting of parameters”].
*3: The decimal point position changes by the setting of input
type and linear decimal point.
*4: The deadband is initialized by resetting of EV mode.
*5: For thermocouple or resistance input, the linear decimal
point can not be changed. (display only)
*6: The range changes by the setting of input type.
