Sensor correction function
This corrects the input value from the sensor. When a sensor cannot be set at the exact location wherecontrol is desired, the sensor measured temperature may deviate from the temperature in the controlled
location.
When controlling with plural controllers, sometimes the measured temperatures (input value) do notconcur with the same setting value due to difference in sensor accuracy or dispersion of load capacities.
In such a case, the control can be set at the desired temperature by adjusting the input value of sensors.

4. Operation
After the unit is mounted to the control panel and wiring is completed, operate the unit following theprocedures below.
(1) Turn the power supply to the ECS-200 ON.
] for approx. 3 seconds during
After the power is switched on, the Digital display indicates [warm-up.
During this time, all outputs and LED indicators are in OFF status.
After that, the actual temperature (PV) or main set value (SV) is indicated on the Digital display,and control starts.

CautionDuring the warm-up status (for approx. 3 seconds), do not operate any keys since the instrument
specifications may be altered.
Do not turn the power supply ON during key operation.
(2) Input the set value.
Input each set value, referring to Chapter “3. Settings”.
(3) Turn the load circuit power ON.
Control action starts so as to keep the control target at the main set value.

5. Other functions(1) Operational error protection function
If a key operation has not been performed for approx. 30 seconds during the Basic function setting modeor Auxiliary function setting mode, the controller automatically switches to the PV/SV display mode, andthe set value is registered.
(2) Sensor burnout alarm (Burnout, upscale)If the thermocouple is burnt out, the control output is turned OFF and the Sensor burnout alarm] flashes.
action indicator lights. At this time, if the PV is indicated on the Digital display, [(Once the alarm activates, the output is held until the power to the instrument is switched OFF.)
When the PV exceeds 999 of “K” input, 900 of “J” input, 350 of Pt100 input, the same action
occurs as the above.
(3) Self-diagnosis
The CPU is monitored by a watchdog timer, and when any abnormal status is found on the CPU,the controller is switched to warm-up status.
(4) Automatic cold junction temperature compensation (only for thermocouple input)
This detects the temperature at the connecting terminals between the thermocouple and the instrument,
and always maintains the same status as when the reference junction is located at 0 (32 ).

6.5 Auto-reset (offset correction)
Auto-reset is performed to correct the offset at the point at which PV indication is stabilized within the
proportional band during the PD action.
Since the corrected value is internally memorized, it is not necessary to perform the auto-reset again
as long as the process is the same.
• Auto-reset does not work in the ON/OFF control action mode.
• Make sure to press the RST key just once.
If the RST key is pressed twice or more, the offset will not be corrected normally.

7.5 Mounting[When using screw type mounting bracket]
Mounting panel thickness is within 1 to 8mm.
Insert the unit from the front of the control panel.
Slot the mounting bracket to the holes at the top
and bottom of the case, and fasten with screws.
When using the soft front cover (FC-48-S),
the panel thickness is within 1 to 7.5mm.

[When using one-touch type mounting bracket]
Mounting panel thickness is within 1 to 3mm.
First, mount the one-touch type mounting
bracket at the top and bottom of the controller.
Then insert the controller from the front of thepanel.
When using the soft front cover (FC-48-S),
the panel thickness is within 1 to 2.5mm.

NoticeAs the case is made of resin, do not use excessive force while screwing in the mounting bracket,
or the case could be damaged.
The torque is approximately 0.4N•m.

Caution• The terminal block of the ECS-200 is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and tightened with theterminal screw.
• Use a thermocouple and compensating lead wire according to the sensor input
specifications of this controller.
• Use the 3-wire RTD which corresponds to the input specifications of this controller.
• This controller does not have built-in power switch or fuse. Therefore it is necessary to installthem in the circuit near the external controller.
• 24V AC or DC is usable as a power source, however, do not confuse polarity when using
direct current (DC).
• When using a relay contact output type, externally use a relay according to the capacity of theload to protect the built-in relay contact.
• When wiring, keep input wires (Thermocouple, RTD, etc.) away from AC sources or load
wires to avoid external interference.
