Do you have a question about the Samwon ENG SU-105 and is the answer not in the manual?

The SAMWON ENG SU-105 is an instrument designed for automatic temperature control, offering both On/Off and Proportional-Integral (PI) control methods. It supports various sensor types, including K-type and T-type thermocouples, Pt100 Resistance Temperature Detectors (RTDs), and IC sensors, making it versatile for a range of temperature monitoring and control applications.

Function Description:

The primary function of the SU-105 is to maintain a desired temperature by controlling external heating or cooling elements. It achieves this through two main control modes:

On/Off Control: This mode simply switches the output on or off based on whether the current temperature is above or below the setpoint, with an adjustable hysteresis (dIF) from 0.1 to 25.0°C. It also includes an ON Delay Timer (dLt) adjustable from 0 to 300 seconds, allowing for delayed activation of the output.
PI Control: This advanced mode uses proportional (P) and integral (I) compensation to achieve more precise temperature control, minimizing overshoot and steady-state errors. The proportional band is adjustable from 0.1 to 50.0, and the integral compensation helps eliminate offsets. A Period Timer (tYP) from 1 to 120 seconds determines the ON/OFF period for relay output.

The device features two outputs: a Main Output and an Auxiliary Output. The Main Output is dedicated to temperature control (heating or cooling), while the Auxiliary Output can be configured for either Alarm Output or Period Timer Output.

Alarm Output (Auxiliary Output): When configured as an alarm, it can activate based on a separate set temperature (SV2) and a differential range (dF2) from 0.1 to 25.0. It also includes a delay timer (dt2) from 0 to 300 seconds and can be set for heating (H) or cooling (C) direction. This allows for alerts or secondary control actions when the temperature deviates from a specific range.

Period Timer Output (Auxiliary Output): When configured as a period timer, it allows for scheduled ON/OFF cycles. Users can set the time unit (minutes or seconds), the initial output state (ON or OFF), and the ON (ton) and OFF (toF) durations, ranging from 0 to 999. A value of 0 for ton or toF signifies a continuous state. This is useful for applications requiring timed operations independent of temperature.

PRESET OUT Feature: This is a safety feature designed for TH, IC, HUM, and A sensors. In case of a sensor error during operation, it prevents immediate shutdown and instead levels the output value based on prior output data. This helps minimize damage and ensures a more graceful failure mode. It operates only in On/Off control mode, with On/Off times within 1 second/18 hours on average, and recalibrates every 30 outputs.

Lock Feature: An "Installer's RESET" menu allows for locking certain features (Hysteria, Delayed time, direction) to prevent unauthorized changes, ensuring system stability. The "Allowance of range" feature can limit the preset temperature range.
Sensor Compensation: The SU-105 allows for sensor compensation (rSt) to correct for inaccuracies caused by long sensor wires or environmental factors, ensuring precise temperature readings.
Decimal Point Adjustment: The decimal point position can be adjusted for different levels of precision in temperature display.
Panel Mount Design: The device is designed for panel mounting, with a cutout size of 70+0.6 mm x 28+0.6 mm, and external dimensions of 76 mm (width) x 34 mm (height) x 70 mm (depth).

Maintenance Features:

Error Detection: The device displays "Err" in case of wiring errors or sensor malfunctions.
PRESET OUT for Sensor Errors: As described above, this feature helps mitigate the impact of sensor errors by leveling output values, preventing abrupt shutdowns and allowing for continued operation in a controlled manner.
Clear Wiring Diagram: The manual provides a clear wiring diagram for connecting sensors, power, and outputs, facilitating correct installation and troubleshooting.
Robust Design: Built to operate within a temperature range of 0°C to 50°C and humidity below 85% RH, ensuring reliability in various industrial environments.

Safety Precautions:

The manual emphasizes several safety precautions:

Electrical Shock: Do not access AC terminals while in use. Always shut down electrical power before checking power input.
Environmental Protection: Prevent ingress of dirt, water, oil, and cable debris to avoid damage and fire hazards.
No Modifications: Do not modify or disassemble the product, as this can cause critical damage.
Wiring: Connect terminals by confirming polarity and usage. Isolate wiring from high-voltage cables, electrical power, and motors to prevent noise.
Avoid Harsh Conditions: Protect from dirt, corrosive gases, oil, humidity, freezing, direct sunlight, vibration, and altitudes higher than 2,000m.
Power Switch/Breaker: Use a power switch or circuit breaker (IEC947-1 or IEC947-3 equivalent) for shutdown.
Sensor Wiring: Use authorized compensating lead wires for thermocouples and RTDs. For RTDs, ensure three wires of the same thickness and length are used.
Noise Prevention: Isolate the product from power cables and avoid equipment that generates strong high-frequency noise (e.g., welding machines).
Mobile Radio: Refrain from using mobile radios near the device, as they may cause defects.
Lightning/Thunder: Turn off the controller during lightning and thunder.
