[Problem] When nothing is connected of S272 but alarm light of the device will turn on.
[Possible causes and solutions]
(1) Please check whether the external power supply of the equipment is connected or not, and the external power failure will alarm.
(2) Connect the device to the computer, open the configuration software, and read the DIN trigger setting page on the configuration software to check whether the DIN setting of some channel is normally closed. If it is not used, it can be disabled.
(3) Connect the device to the computer, open the configuration software, and read the AIN trigger setting page on the configuration software to check if there are some AIN high and low limit settings that have exceeded the currently read value. If you don't use it, you can disable it or change it to a range that won't trigger.
