FAQ
Q: What is the operating temperature range for the OHTS1060?
A: The suitable operating temperature range is -10°C ~ +50°C. Operation outside this range may result in decreased measurement accuracy or equipment damage.
Q: Can this sensor be used as a safety or emergency stop device?
A: No, this device is strictly prohibited from use as a safety device or emergency stop device, and shall not be used in applications where equipment failure may cause personal injury.
Q: What precautions should be taken regarding the installation environment?
A: The humidity sensor utilizes capacitive sensing principles and should be protected from use in environments containing volatile organic compounds (VOCs), as such environments may cause sensor drift or damage. Ensure good ventilation around the sensor, avoiding direct sunlight and heat source interference.
Q: What are the electrical safety requirements for installation?
A: Ensure power is disconnected before wiring to avoid energized operation. Supply voltage must not exceed 30VDC, otherwise permanent equipment damage may occur. RS485 bus shall utilize shielded twisted pair cable with A and B lines correctly connected.
Q: What are the requirements for RS485 bus wiring and device addressing?
A: Each device address on the same bus must be unique with factory default address of 0x01. When bus length exceeds 2000m or excessive devices are connected, local power supply and 120Ω termination resistors are required.
