Hired-Hand Farm Hand Series: Swine Finisher - Manual (Page 6)

Part No. 4801-0150 Rev 8-04 Farm Hand Swine Finisher 5 Stage 6 of 32
Important: In the following descriptions, many references are made to the Main Curtain (Unit
1). If you do not have a Main Curtain or do not wish to use the auxiliary
connection as shown in Section 11.3, you must place a jumper across the signal
terminals for Unit 1. This manipulates the controller into thinking the main
curtain is closed. In turn, this allows the heat and negative stages to operate.
6.1 Stage Parameters
The following parameters are used to program each stage on the Farm Hand Swine Finisher.
Through these parameters, the user has complete control over the operation of each stage. The
following sections explain each parameter in detail.
P1 = Stage Sensors
P2 = Stage Mode
P3 = Stage Timer Settings
P4 = Stage ON Point
P5 = Stage OFF Point
6.1.1 Stage Sensors (P1)
The Swine Finisher triggers stage operations from temperature sensors. The stage sensor
parameter (P1) sets which sensor(s) the controller uses to regulate stage operation.
P1 options are as follows:
10 = Sensor 1
Sensor 1 is used. The controller will ignore sensor 2.
02 = Sensor 2
Sensor 2 is used. The controller will ignore sensor 1.
12 = Average of Sensors 1 & 2
The average temperature of sensor 1 and sensor 2 is used.
6.1.2 Stage Mode (P2)
The Farm Hand Swine Finisher is a very intelligent controller, therefore, it needs to not only know
whether this is a heating or cooling stage but also what type of cooling stage. The Farm Hand
Swine Finisher reacts not only to temperature but also curtain position. This feature allows the
grower to program the cooling stages to work exactly like he wants them to without the expense
of hard wiring through relays and limit switches. This feature allows the Farm Hand Swine
Finisher to better react to the environment. Any Stage can be programmed to be one of the
following:
01 = Heat
This mode allows the equipment to operate when room temperature is below the
ON Point for the stage, and the curtains are closed.
02 = Cool Stir
This mode setting allows the cool stage to run whether the main curtain is open or
closed. The only time that this mode will not run is during tunnel mode.
03 = Cool Negative
This mode setting only allows the cooling stage to run if the main curtain is
closed, hence the name Negative. This stage will not run if the controller is in
tunnel mode.
04 = Cool Negative Tunnel
This mode setting works exactly like the Cool Negative setting except it will run if
the controller goes into tunnel mode. This stage is sometimes referred to as a
transitional stage. In other words, it operates before it goes into tunnel and also
during tunnel.
