  • Page 3 The room temperature of the room in which the controller is located MUST ALWAYS REMAIN BETWEEN 32° AND 104°F (0° AND 40°C). To avoid exposing the controller to harmful gases or excessive humidity, it is preferable to install it in a corridor. DO NOT SPRAY WATER ON THE CONTROLLER PF-6.rev.14...
  • Page 4 FEATURES The PF-6 is an electronic device used for air inlet control in livestock buildings. In combination with an environment controller, the PF-6 coordinates the movement of the air inlets with the operation of the fans using a potentiometer located on the panel drive. Additional units can be connected to the PF-6 for an independent control of additional air inlets.

  • Page 7 Integrating an air inlet control system into your ventilation system requires the following equipment: a Comlink-2 communication module added to your controller a PF-6 controller for each air inlet panel (up to 100 in all) an alarm system (optional) a DC power supply (optional) a power unit equiped with a 10 turn potentiometer (>...

  • Page 9 TEMPERATURE PROBES: If your PF-6 unit is supplied with a tempera- ture probe, connect it to terminal PROBE #1 and set internal switch #5 to ON. Note that the PF-6 will operate with no temperature probes connected to it. However, the room temperature position on the func- tion selector will not function in this case.
  • Page 10 JUMPERS The PF-6 network operates on two communication lines. One line links the PF-6 units together to the main controller and the other line links temperature controllers to a computer (this second line is optional). Two jumpers on the Comlink-2 card are used to identify the end of line for each communication line.

Drill a 5/16" hole through the bottom of the controller and thread the communication cable through the hole. Use the grommet provided to secure the cable.
  • Page 13 5. CONFIGURE THE PF-6'S AS PRIMARY / SLAVE If your installation requires more than one PF-6 unit for independent control of different air inlets, one of the PF-6's will be configured as the primary unit and the others will be configured as slaves. Up to 99 slave units can be connected in this way.
  • Page 14 PF-6 6. VERIFY PF-6 OPERATION Power the PF-6 and set the function selector to MANUAL MODE position. Use the adjustment knob to select OPN to open, CLO to close or OFF to stop the winch. Verify motor operation: Open and close the air inlet panels using the open-close switch.
  • Page 15 PF-6 OPERATION The PF-6 adjusts the air inlet opening according to the operation of the temperature controller ventilation stages. As the temperature increases and new stages are activated, the inlet is opened or closed accordingly. The ventilation curve is divided into steps and the user must program a new air inlet position for each step.
  • Page 16 PF-6 The other steps follow according to the ventilation curve. A step is added each time a new stage is activated by the temperature controller. Figure 2 below shows an example of this. Figure 2 Ventilation Curve with Constant-Speed Stages Only...
  • Page 17 PF-6 A step is also added when the speed on a variable speed stage reaches 100% without activating a new stage. Figure 3 below illustrates this. In this example, a step is added when the first ventilation stage reaches full speed at “ temperature set point + bandwidth 1 ” even though no new stages are activated at this point.
  • Page 18 Normal Mode: To use normal mode, set internal switch #8 to OFF. The PF-6 gradually opens or closes the panels in a linear fashion as the room temperature rises above the last reference point temperature. The air inlet opening reaches the percentage specified for the over-opening when the room temperature is equal to "temperature of the last reference point +...
  • Page 19 PF-6 Drop Mode: To use drop mode, set internal switch #8 to ON. The PF-6 maintains the inlet opening at the value of the last controller stage as the temperature rises above the last reference point temperature. When the temperature reaches "temperature of the last reference point + over-opening band-...
  • Page 20 PF-6 internal switches: Set the lock switch to OFF in order to unlock the automatic mode.
  • Page 21 1. Turn the function selector to PROGRAMMING function then set internal switch #7 to ON on all PF-6 units. If the calibration led on a unit is flashing, set switch #7 to OFF and then back to ON. Air inlets are completely closed and the display shows CLO.

  • Page 23 In other words, the two values are reset to the current opening value. To avoid resetting minimum and maximum values, return to the current opening display using the adjustment knob (clockwise or counterclockwise) before the 10 second delay has elapsed. PF-6.rev.14...
  • Page 24 PF-6 IDENTIFICATION NUMBER This function displays the identification number of the PF-6 along with its primary/slave status. The identification number is set using jumpers on the printed circuit board (see chapter on installation). Note that this function is not available during calibration Settings The identification number is displayed, alternating with "ID"...
  • Page 25 PF-6 OVER-OPENING SETTING The over-opening bandwidth is used to open the air inlet further when the last reference point temperature has bean reached. It can be adjusted from 0.5 to 20°F (0.3 to 11.1°C). Note that this function is not available dur- ing calibration.
  • Page 26 PF-6 PROGRAMMING This function is used to calibrate the air inlet opening for each calibration step. A step is created each time a new stage is activated or whenever the speed on a variable speed stage reaches 100% without activating a new stage.
  • Page 27 "AL,X" where X is the alarm number If the potentiometer is defective, the PF-6 will operate in security mode: when the room temperature is 2°F above the set point, the inlet opens according to the cycle: 5 seconds ON, 120 seconds OFF.
  • Page 28 PF-6 ALARMS - HIGH This function is used to adjust the offset for the high temperature alarm. The alarm contact is activated when the room temperature exceeds "temperature set point + high alarm offset" as shown below. The offset can be adjusted from 0.5°F to 40°F (0.3°C to...
  • Page 29 PF-6 ALARMS - LOW This function is used to adjust the offset for the low temperature alarm. The alarm contact is activated when the room temperature drops below "temperature set point- low alarm alarm offset" as shown below. The offset can be adjusted from 0.5°F to 20°F (0.3°C to 11.1°C).
  • Page 30 PF-6 ROOM TEMPERATURE This function gives a readout of the current room temperature, minimum maximum temperature values can also be displayed. Internal switch #5 must be set to ON and a temperature probe must be connected for this function to work.
