Frequently Asked Questions - KP-810-30-B BGH
How to wire the power supply?
Connect the power supply to terminals 1 and 2 as marked on the housing. Use a 250V fuse rated for the device power consumption (≤5 VA). Ensure the controller is grounded via the grounding terminal.
What sensor types are supported?
The KP-810-30-B supports thermocouples (types K, J, T, E, R, S) and RTD Pt100 sensors. Select the appropriate sensor type in the configuration menu.
How to perform auto-tuning for PID?
Press and hold the 'SET' key for 3 seconds to enter parameter settings. Navigate to 'At' parameter and set it to '1'. The controller will automatically determine the optimal PID parameters. Tuning may take a few minutes.
What does the alarm output do?
The alarm output is a relay that activates when the measured value exceeds or falls below the set alarm thresholds. You can configure high/low alarms and deviation alarms in the settings.
How to change the setpoint?
Press the 'SET' key once to display the setpoint (SP). Use the up/down arrow keys to adjust the value. Press 'SET' again to confirm. The new setpoint will be saved.
What is the maximum load for the output relay?
The relay is rated for 5A at 250VAC for resistive loads. For inductive loads (motors, contactors), derate to 2A and add a snubber circuit to protect the relay contacts.
How to reset to factory defaults?
In the parameter setting mode, navigate to 'Pno' password entry and enter '1111' (default password). Then select 'Ini' and set it to '1'. The controller will reset all parameters to factory defaults.
Can I use this controller for heating and cooling?
Yes, the controller can be configured for both heating and cooling applications. In the output configuration, you can select 'HEAt' or 'COOL' mode. For dual output (heat/cool), you need an additional output module (not included).
What should I do if the display shows 'Err'?
An 'Err' message indicates a sensor fault. Check the sensor wiring for breaks or shorts. Ensure the sensor type selected matches the connected sensor. If using a thermocouple, verify polarity.
How to clean the controller?
Disconnect power before cleaning. Use a soft, dry cloth to wipe the front panel. Do not use solvents or abrasive cleaners. For stubborn dirt, slightly dampen the cloth with water.
