Honeywell Description of Parameters 199
1032 Interlock selection 7 (2.9.23)
With this parameter you can activate or deactivate the feedback signal from the drives.
The interlock feedback signals come from the switches that connect the motors to the
automatic control (frequency drive), directly to the mains or place them to off-state. The
interlock feedback functions are connected to the digital inputs of the frequency drive.
Program parameters ID426 to ID430 to connect the feedback functions to the digital
inputs. Each drive must be connected to its own interlock input. The Pump and fan
control controls only those motors whose interlock input is active.
0 Interlock feedback not used
The frequency drive receives no interlock feedback from the drives
1 Update of autochange order in Stop
The frequency drive receives interlock feedback from the drives. In case one of the
drives is, for some reason, disconnected from the system and eventually re-connected, it
will be placed last in the autochange line without stopping the system. However, if the
autochange order now becomes, for example, [P1 P3 P4 P2], it will be updated
in the next Stop (autochange, sleep, stop, etc.)
Example:
[P1 P3 P4] [P2 LOCKED] [P1 P3 P4 P2] [SLEEP] [P1 P2 P3
P4]
2 Update of order immediately
The frequency drive receives interlock feedback from the drives. At re-connection of a
drive to the autochange line, the automatics will stop all motors immediately and re-start
with a new set-up.
Example:
[P1 P2 P4] [P3 LOCKED] [STOP] [P1 P2 P3 P4]
1033 Actual value special display minimum 57 (2.2.46, 2.9.29)
1034 Actual value special display maximum 57 (2.2.47, 2.9.30)
1035 Actual value special display decimals 57 (2.2.48, 2.9.31)
1036 Actual value special display unit 57 (2.2.49, 2.9.32)
The Actual value special display parameters are used to convert and display the actual
value signal in a form more informative to the user.
The Actual value special display parameters are available in PID Control Application and
Pump and Fan Control Application:
Example:
The actual value signal sent from a sensor (in mA) tells you the amount of waste water
pumped from a tank per second. The signal range is 0(4)…20mA. Instead of receiving
the level of the actual value signal (in mA) on the display, you wish to receive the amount
of water pumped in m 3 /s. You then set a value for par. ID1033 to correspond to the minimum
signal level (0/4 mA) and another value for par. ID1034 to correspond to the maximum
signal level (20 mA). The number of decimals needed can be set with par. ID1035
and the unit (m 3 /s) with par. ID1036. The level of the actual value signal is then scaled
between the set min and max values and displayed in the selected unit.
