Setting 21: Run (AUTO Mode)
Starts and stops the bypass when Z1-08 is set to 1.
Setting 22: Run Enable (Safety)
Stops the drive from running regardless of Z1-08 setting. Z2-31 controls the message displayed on the HOA keypad when this
input is open.
Note: Multiple digital input terminals can be programmed for "Run Enable (Safety)" (Z2-0o = 22). The drive will run only when all digital inputs
programmed for "22" are active. This feature applies to settings 0 and 22. All other selections should only be set once in parameters Z2-01
to Z2-08.
Setting 23: Run Interlock (BAS)
Stops the drive and triggers alarm AL02. Use parameters Z1-13 and Z1-15 to modify Interlock settings.
Setting 24: Remote Transfer to Bypass
Stops the drive and turns on the bypass when a Run command is issued while in Drive Mode. The fault for this mode is
controlled by parameter Z1-05. Parameter Z1-40 controls the length of time that the drive must be faulted before switching to
Bypass Mode.
Setting 25: Smoke Purge Bypass Run to Destruction
Stops the drive, turns on the bypass, and triggers alarm AL03. The bypass runs continuously regardless of any faults or alarms.
Setting 26: Smoke Purge Drive Run to Destruction at Smoke Purge Preset Speed
Bypass controller will stay in this state even if the drive faults or is unavailable. The preset speed is equal to the value set to
Z1-10.
Setting 27: Motor OR Select
2-Motor OR function; 0/1 for Motor 1/2. Behavior defined by Z1-11.
Setting 28: Motor AND Select
2-Motor AND function; 0/1 for 1/2 motor. If 1 motor, then look to Motor OR input for selected motor. Behavior defined by
Z1-11.
Setting 29: Motor 1 Overload Contact
When input is open, declare an oL Fault, issue an EF0 fault to the drive, delay per EF0 Fault Delay Time (Z1-30), and open
bypass (K3) contactors.
Setting 30: Motor 2 Overload Contact
When input is open, declare an oL Fault, issue an EF0 fault to the drive, delay per EF0 Fault Delay Time (Z1-30), and open
bypass (K3) contactors.
Setting 31: HAND Select
When this is selected, the HAND function command will come from a digital input while the HAND key on the HOA operator
will be ignored. If both HAND and AUTO functions are configured to come from digital inputs, the lack of both of these
inputs being active will put the HOA function into the OFF state. The OFF key on the HOA operator will always place the
HOA function to the OFF state.
Setting 32: AUTO Select
When this is selected, the AUTO function command will come from a digital input while the AUTO key on the HOA operator
will be ignored. If both HAND and AUTO functions are configured to come from digital inputs, the lack of both of these
inputs being active will put the HOA function into the OFF state. The OFF key on the HOA operator will always place the
HOA function to the OFF state
Setting 33: DRIVE/BYPASS Select
When this is selected, the DRIVE/BYPASS select function command will come from a digital input while the DRV/BYP key
on the HOA operator will be ignored.
