Hired-Hand Farm Hand Series: Swine Finisher - Manual (Page 7)

Part No. 4801-0150 Rev 8-04 Farm Hand Swine Finisher 5 Stage 7 of 32
05 = Cool Tunnel
This mode setting only works when the controller is in tunnel mode.
6.1.3 Stage Mode (P3)
The Farm Hand Swine Finisher is equipped to satisfy any of your minimum ventilation needs for
regular runtime timers and to cool timers.
00 = No Timer
Select 0 for the timer setting if you do not want the stage to be on a timer.
01 = Runtime Timers
Any one of the On/Off stages can be placed on the system timer by
placing a "1" in parameter 3 (P3) of the stage. By doing this the stage
will operate off of the system timer while the temperature is below the
stage's OnPoint. Once the temperature reaches the stage OnPoint, the
stage will come on full time.
02 = Cool Timers
ON/Off Stages
Any one of the On/Off Stages can be placed on a cool timer.
By doing this the stage will operate off the system timer only while the
temperature is above the stage OffPoint (OFF). Refer to Section 9.3
"Cool Timer Stage Operation" for proper setup.
Variable Stages
Any of the variable stages can be placed on a cool timer. By doing this
the stage will be placed on the system timer all the time. It will run full
speed for a certain percentage of time which is set in Var Timer/PCT.
This percentage will progressively increase as the temperature rises
above the minimum OnPoint setting (OFF). Refer to Section 9.5
"Variable Speed Fan Control" for proper setup.
6.1.4 Stage OnPoints (P4)
The OnPoint setting is the temperature at which a stage turns on. (i.e. the temperature at which a
start signal is transmitted by the controller). The OnPoint setting of a 'cool' stage will always be
greater than the target temperature. The OnPoint setting of a 'heat' stage will always be less than
the target temperature. The temperature controller will automatically limit settings accordingly.
6.1.5 Stage OffPoints (P5)
The OffPoint setting is the temperature at which a stage turns off.
6.1.6 Minimum Runtime Percentage (P10) (Variable Stages Only)
This setting is the percentage of the system timer that the variable stage will run at minimum
speed if the stage sensor's temperature is below the Minimum OnPoint (OFF) for the stage.
