HVAC400X – APPLICATION MANUAL
P3.5.1.4 CONTROL SIGNAL 2 B (ID 424)
You can use this parameter to select the digital input signal (Control Signal 2) that starts and stops the drive when
the control place is I/O B.
P3.5.1.5 I/O B CONTROL FORCE (ID 425)
You can use this parameter to select the digital input signal that switches the control place from I/O A to I/O B.
P3.5.1.6 I/O B REFERENCE FORCE (ID 343)
You can use this parameter to select the digital input signal that switches the frequency reference source from I/O
A to I/O B.
P3.5.1.7 EXTERNAL FAULT CLOSE (ID 405)
You can use this parameter to select the digital input signal that activates an external fault.
P3.5.1.8 EXTERNAL FAULT OPEN (ID 406)
You can use this parameter to select the digital input signal that activates an external fault.
P3.5.1.9 FAULT RESET CLOSE (ID 414)
You can use this parameter to select the digital input signal that resets all active faults.
Active faults are reset when the state of the digital input changes from open to closed (rising edge).
P3.5.1.10 RUN ENABLE (ID 407)
You can use this parameter to select the digital input signal that sets the drive to Ready state.
When the contact is OPEN, the start of the motor is disabled.
When the contact is CLOSED, the start of the motor is enabled.
To stop, the drive obeys the value of P3.2.5 Stop Function.
If you open Run Enable during the operation of the drive, the drive stops.
NOTE: The state of the drive remains in 'Not Ready' if the state of this signal is 'opened'.
P3.5.1.11 RUN INTERLOCK 1 (ID 1041)
You can use this parameter to select the digital input signal that prevents to start the drive.
The drive can be ready but start is not possible when the state of the interlock signal is 'open' (damper interlock).
If an interlock is active, the drive cannot start.
You can use this function to prevent the start of the drive when the damper is closed. If you activate an interlock
during the operation of the drive, the drive stops.
P3.5.1.12 RUN INTERLOCK 2 (ID 1042)
You can use this parameter to select the digital input signal that prevents to start the drive.
The drive can be ready but start is not possible when the state of the interlock signal is 'open' (damper interlock).
If an interlock is active, the drive cannot start.
You can use this function to prevent the start of the drive when the damper is closed. If you activate an interlock
during the operation of the drive, the drive stops.
P3.5.1.13 ACC/DEC TIME SELECTION (ID 408)
You can use this parameter to select the digital input signal that switches to the ramp 2 instead of the standard
ramp 1.
