become active/in both directions?
Thread Content
Logic Switch Points Logic Switch Points For a temperature switching point to become active, 5 out of 8 transmitters must be in the direction of the switch type. If it is a High switch point then 5 out of 8 transmitters must be greater than the setpoint. If it is a Low switch point then 5 out of 8 transmitters must be less than the setpoint. All temperature switching points will have a deadband of 5 Deg C and debounce time of xx seconds. The debounce time is applied in both directions. In order for a temperature switching point to function, 5 of the 8 transmitters must be in the switching type direction. If it is a high switching point, 5 of the 8 transmitters must be greater than the set value. If it is a low switching point, 5 of the 8 transmitters must be less than the set value. All temperature switching points will have a 5°C deadband and xx seconds jump time. Jump times apply in both directions.

“"Two directions" refers to the two temperature switching directions of High and Low. Debounce time means that you cannot switch to another temperature direction within XX seconds after the temperature switch. Can be translated as follows: The above XX seconds jump time applies to both temperature switching directions (High and Low).
For a temperature switching point to become active, 5 out of 8 transmitters must be in the direction of the switch type. How do you understand become active/be in the direction of the switch type?
personal understanding: become active, activate be in the direction of switch type, among the 8 transmitters in conversion mode, 5 are in conversion mode. In addition, transmitter also means sensor. I wonder if there is also a temperature sensor here?
transmitter here is the "transmitter", which converts the temperature signal measured on site into an electrical signal and transmits it to SIS/DCS.
For a temperature switching point to become active, 5 out of 8 transmitters must be in the direction of the switch type. This sentence mainly talks about the problem of chain activation. Switch means chain. In the past, many chains were implemented with solenoid valves, two positions. In order to achieve temperature chain activation, the eight-to-five transmitters must be in the same chain state. That is to say, when five of the eight temperature transmitters reach a certain temperature, the temperature chain will take effect. Of course, all eight temperature transmitters have interlocking functions. The stove here also has a similar interlock, but it was later cut off, making it difficult to operate. The speaker is probably also translating the content of the temperature control part of a certain furnace in ethylene.
In order to control the temperature of the furnace within a certain range without causing harm, a temperature chain is used to protect the device. Of course, the occurrence of the chain generally has a delay, that is, how long does it take for the chain effect to occur after reaching the chain value. If there are several inaccurate temperature measurements or large deviations or temperature transmitter failures, it is usually one or two. How many of the eight are accurate? So we choose five from eight instead of eight from eight. Five out of eight reached the chain value at the same time, indicating that there is a problem with the temperature control. In order to protect the device and equipment, the chain must be activated. In this way, the poster should have a clear understanding of the meaning and function of chaining.
For a temperature switching point to become active, 5 out of 8 transmitters must be in the direction of the switch type. There is another problem that I didn't pay attention to. Basically agree with 6th floor. It’s 5 out of 8. But from the context, the temperature switch here is a two-point temperature control, not a temperature chain. In the direction of the switch type means that the switching condition is reached, that is, the switching setting value is exceeded. Trial translation is as follows: To trigger a temperature switch, five of the eight transmitters must reach the switch condition (exceed the switch setpoint).
For a temperature switching point to become active, 5 out of 8 transmitters must be in the direction of the switch type. Temporarily translated as: In order to activate the temperature switching point, five of the eight transmitters must reach the switching condition.

I didn’t read the discussion process carefully, but my understanding of “active” may be relative. That is to see what state or stage the system is in. “Five of the eight transmitters must meet the switching conditions." This expression seems incomplete, that is, =5 active. It may be to buy time, and the minority obeys the majority. Greater than or equal to 5 active may be for security or training, etc. Mathematically, 5/8=0.625, which is relatively close to the golden section in the traditional sense. It may be for good luck or to make "wealth", haha, it is just a joke. This post was last edited by wwwyyhbmt on 2008-2-24 01:47 ]
Today I was translating the patent agent’s documents, and switchpoint appeared many times in the text. It can be alarm and interlock (including parking interlock and other interlock). In short, it is better to translate flexibly depending on the context. Here, it obviously means something related to interlocking.
