Yes — please observe the maximum temperature and do not mix thermocouple types.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eQ. Which wire is positive?\u003c\/em\u003e\u003cbr\u003eA. On current UK\/European IEC 60584 cable, green is positive and white is negative, with a green sheath. Older UK BS1843 cable uses brown positive and blue negative with a red sheath. US ANSI cable uses yellow positive and red negative — note red is negative here. If the leads are unmarked, the negative leg is slightly magnetic.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eQ. What happens if the polarity is reversed?\u003c\/em\u003e\u003cbr\u003eA. The reading moves the wrong way as temperature rises, so the controller cannot hold setpoint. Swap the two leads at the controller terminals.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eQ. Can the thermocouple cable be extended?\u003c\/em\u003e\u003cbr\u003eA. Yes, using Type K extension (KX) or compensating (KCB) cable with Type K plugs and sockets. Do not use ordinary copper cable — it creates an extra junction that causes errors whenever the joint is at a different temperature to the controller. A quality shielded cable is strongly recommended where the environment contains industrial equipment.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eQ. What is the maximum permissible cable length?\u003c\/em\u003e\u003cbr\u003eA. There is no official limit. To preserve signal quality, 30M should be considered a realistic working maximum.
