How should this sentence be understood: \"The output from the Ups to the solenoid actuated valves has to be shut off in case the supply voltage is 110V\"? ?
If the voltage drops to 110V, the UPS will stop supplying power to the solenoid valve. It means that if the voltage of your UPS drops to 110V, it should be shut down
The output from the UPS to the solenoid-actuated valves must be shut off if the supply voltage drops to 110V; when the voltage falls to 110V, the output from the UPS to the electromagnetic drive valves needs to be turned off.
Passive sentences: distinguish between subject, predicate, object, attributive, adverbial, and complement. ^_^ Once the voltage reaches 110V, the UPS power supply feeding the solenoid valve is cut off. 1. It is not necessarily to turn off the solenoid valve; it could also be to turn it on, depending on the type of solenoid valve. 2. When the voltage reaches 110V, it may not decrease; it could also increase, depending on the control conditions. 3. It is necessary to consider the sentences before and after; based on this single sentence alone, it is not possible to determine whether it is the UPS power supply that reaches 110V, or whether it is some other power supply that reaches 110V before the UPS power supply’s switch starts to operate.
