Corrects errors from external input temperature sensors.

9. Input Digital Filter [MAvF]

Stabilizes current temperature value (PV) to prevent fluctuating MV and enable stable control.

• LLLL: Measured sensor input lower than temperature range.

Installation

Insert the product into a panel and fasten the bracket. Ensure proper wiring and space for heat radiation. Warm up the unit for over 20 minutes after power-on for accurate measurement.

Parameter Reset

Hold the front +, +, + keys for 5 seconds to enter the parameter reset [INIT] parameter. Select 'YES' to reset all parameters to factory default or 'NO' to maintain previous settings. Parameter reset is unavailable if parameter lock [LOC] is set or auto-tuning is in progress.

Cautions during Use

• Follow instructions in 'Cautions during Use' to avoid accidents.
• Check terminal polarity before wiring temperature sensors. Use same thickness and length cables for RTD sensors. Use designated compensation wire for thermocouple sensors.
• Keep away from high voltage lines or power lines to prevent inductive noise. Use shielded wire for input signal lines.
• Install a power switch or circuit breaker in an easily accessible place.
• Do not use the unit for purposes other than temperature control.
• Turn off power before changing the input sensor and modify the corresponding parameter.
• 24VAC, 24-48VDC power supply should be insulated and limited voltage/current or Class 2, SELV.
• Make required space around the unit for heat radiation.
• Ensure power supply voltage reaches rated voltage within 2 seconds after supplying power.
• Do not wire to unused terminals.
• This unit may be used in indoors, at altitude max. 2,000m, pollution degree 2, installation category II.
