Figure 1. 2 and 3-Wire Control Wiring Examples
Important: Some parameters are unaffected by either the 2-Wire or 3-Wire initialization. The following parameters will not be reset
when parameter A1-03 = 2220 or 3330:
■ A1-04 Password Entry
Setting Range: 0 ~ 9999
Factory Default: 0
If parameters A1-01 through A1-03 are locked (unchangeable), they can be unlocked by entering the correct password number into
A1-04.
Once the correct password number is entered and the specified parameters are unlocked, a 2-Wire or 3-Wire initialization will reset the
password to 0000.
Note: A1-04 will return to “0000” when the password has been entered.
■
A1-05 Select Password
Setting Range: 0 ~ 9999
Factory Default: 0
When the value set into A1-04 does NOT match the value set into A1-05, parameters A1-01 thru A1-03 cannot be changed. All other
parameters determined by A1-01 can be changed. Parameter A1-05 can be accessed by displaying parameter A1-04, then press and hold
the RESET key along with the MENU key simultaneously.
