Output Frequency
Example 1: To lock the output frequency, 12 groups of binary codes are 000000000001, and the set password value is 0001.
Example 2: Lock the output frequency, sensor type and the second signal source of control output, 12 groups of binary codes
are 100001000001, and the set password value is 4101.
Example 3: Lock output frequency, the first signal source of main output and the second signal source of main output, 12
groups of binary codes are 000000000111, and the set password value is 0007.
When "Password Lock Parameter Range" is set to 9999, all parameters marked with "*" will be locked.
