Hired-Hand Farm Hand Series: Swine Finisher - Manual (Page 14)

Part No. 4801-0150 Rev 8-04 Farm Hand Swine Finisher 5 Stage 14 of 32
From the graph, you can see that at 78
°F, the cool timer stage will run at 70% of the timer
duration. Below 75
°F the stage will never run. Above 81°F the cool timer stage will run at 100%
continuously.
The minimum Runtime Percentage may be set when going through the main display indicators.
9.4 Setting up a Cool Timer Stage
There are two unique parameters used in programming a Cool Timer stage in addition to the other
5 stage parameters. They are P10-P11. The following is an overview of how to program a cool
timer stage:
1. Enter Program Mode by pressing and holding the Mode button for 5 seconds until
P1 is displayed and the red light next to the stage you want to program is lit. This
parameter selects the sensor(s) that this stage watches for on/off operation.
2. Press the + or - button until the desired sensor is displayed. 1= sensor 1; 2 = sensor
2, and 3 = an average of sensors 1 and 2.
3. Press the Mode button again and P2 is shown. This parameter selects what mode the
stage operates as.
4. Press the + or - button until the desired mode is displayed.
5. Press the Mode button until P3 is displayed. This parameter allows you to put a
stage on the system timer (5 or 10 minutes).
6. Press the + or - button until a 2 is displayed.
7. Press the Mode button again and P4 is displayed. This parameter sets the Onpoint
temperature for this stage. Press the + or - button until the desired full runtime
temperature is displayed.
8. Press the Mode button again and P5 is displayed. This parameter sets the Offpoint
temperature for this stage. Press the + or - button until the desired minimum
runtime temperature is displayed.
Note: The following two steps only apply to variable speed stages being used as cool
timers.
9. Press the Mode button again and P10 is displayed. This is where you set the timer
percentage for the times when the temperature is below the offpoint of the stage. If
you want this to be a strictly cool timer set this to “0”.
10. Press the Mode button again. P11 is now displayed. This can be ignored because
the stage will no longer vary the speed.
11. Exit program mode by pressing the Mode button until PS3 has been displayed or by
waiting 1 minute.
12. Now press the Mode button until the green light next to Var./Timer Pct is lit and the
stage status indicator for the stage you are programming to be the cool timer is lit.
Press the + or - button until the desired minimum fan runtime % is displayed.
