• This instrument is intended for use with industrial machinery, machine tools, and measuring equipment. Verify correct usage after consultation with Shinko Technos or its agencies. (Never use this instrument for medical purposes involving human lives.)
• The instrument is designed for installation on a DIN rail in an indoor control panel. If not mounted in a panel, measures must be taken to ensure operators cannot touch power terminals or other high voltage sections.
• External protection devices (e.g., against excessive temperature rise) must be installed, as malfunction could result in serious system damage or injury. Proper periodic maintenance is also required.
• This instrument must be used under the conditions and environment described in this manual. Shinko Technos Co., Ltd. does not accept liability for any injury, loss of life, or damage occurring due to the instrument being used under conditions not otherwise stated in this manual.

Installation Cautions

This instrument is intended for use under the following environmental conditions (IEC61010-1): Overvoltage category II, Pollution degree 2. Ensure the mounting location corresponds to these conditions:

• A minimum of dust, and an absence of corrosive gases.
• No flammable or explosive gases.
• No mechanical vibrations or shocks.
• No exposure to direct sunlight. Ambient temperature: 0 to 50°C (32 to 122°F) that does not change rapidly, and no icing.
• Ambient non-condensing humidity: 35 to 85%RH.
• No large capacity electromagnetic switches or cables through which large current is flowing.
• No water, oil, or chemicals, or where the vapors of these substances can come into direct contact with the unit.
• Note that the ambient temperature of this unit (not the ambient temperature of the control panel) must not exceed 50°C (122°F) if mounted within a control panel, otherwise the life of electronic components (especially electrolytic capacitors) may be shortened.

EVT Output

• Alarm output: (Alarm, Loop break alarm, and optional Heater burnout alarm utilize common output terminals.) The alarm action point is set by ± deviation from the SV (excluding Process alarm). If the input goes outside the range, the alarm is turned ON or OFF (High/Low limit range alarm). When De-energized action is selected, the alarm is activated conversely.
• Setting accuracy: Same as base accuracy.
• Action: ON/OFF action.
• Hysteresis: Thermocouple, RTD inputs: 0.1 to 100.0°C (°F). DC voltage, current inputs: 1 to 1000 (decimal point placement follows selection).
• Output: Open collector, Control capacity: 0.1 A 24 V DC.
• Alarm types: High limit alarm, Low limit alarm, High/Low limits alarm, High/Low limits independent alarm, High/Low limit range alarm, High/Low limit range independent alarm, Process high alarm, Process low alarm, High limit with standby alarm, Low limit with standby alarm, High/Low limits with standby alarm, High/Low limits with standby independent alarm. Energized/De-energized action applies to these, totaling 24 alarm types. No alarm action can also be selected.
• Alarm Energized/De-energized: Alarm output Energized/De-energized can be selected.
• Alarm HOLD function: Once an alarm is activated, the alarm output is maintained until the power is turned off.
• Loop break alarm output: (Loop break alarm, Alarm, and optional Heater burnout alarm utilize common output terminals.) Detects heater burnout, sensor burnout, and actuator trouble.
• Setting range: Loop break alarm time: 0 to 200 minutes. Loop break alarm span: Thermocouple, RTD inputs: 0 to 150°C (°F) or 0.0 to 150.0°C (°F). DC voltage, current inputs: 0 to 1500 (decimal point placement follows selection).

Key Operation Flowchart

This section outlines the basic operation and setting procedures using the controller's keys.

Basic Operation Procedure

1. Step 1: Select Input Type
   Select the desired input type in the [Input Type] setting.
2. Step 2: Set Alarm Settings
   Select the alarm type in the [Alarm Type] setting. Set the alarm action (Energized/De-energized) in the [Alarm Energized/De-energized] setting. If Alarm HOLD is set, the alarm output will be maintained until power is turned off.
3. Step 3: Set Main Setting Mode
   Adjust the SV (Desired Value) using the [UP] and [DOWN] keys. Press the [MODE] key to register the set value.
4. Step 4: Run
   The display reverts to the PV/SV Display.

About Setting Item Displays

• PV Display: Shows the Process Variable (PV) or setting characters when in setting mode.
• SV Display: Shows the Desired Value (SV), output Manipulated Variable (MV), or other set values during configuration.

Key Operations

• [UP] Key: Increases the numeric value.
• [DOWN] Key: Decreases the numeric value.
• [MODE] Key: Switches between setting modes or registers the set data.
• [SUB-MODE] Key: In combination with the [MODE] key, enters Auxiliary function setting mode 2. This key can be configured for functions such as turning all outputs OFF, switching between Auto/Manual control, or canceling Alarm HOLD.

Auxiliary Function Setting Modes

The controller offers various auxiliary function setting modes for advanced configuration, accessible via the [MODE] and [SUB-MODE] keys. These modes allow for detailed parameter adjustments, including:

• PID Control Parameters: Setting proportional band (P), integral time (I), and derivative time (D) for precise control.
• Alarm Configuration: Defining various alarm types (e.g., High Limit, Low Limit, Process Alarms) and their actions.
• Output Control: Configuring output modes, scaling, and behavior.
• Input Scaling: Adjusting input ranges for different sensors.
• Communication Settings: Configuring serial communication parameters (if applicable).

Refer to the full instruction manual for a comprehensive list and detailed explanation of all setting parameters.
