PRECAUTIONS

We strongly recommend installing supplementary natural ventilation, a failure alarm system as well as a back-up thermostat on at least one cooling stage (refer to the wiring diagram enclosed with this user's manual to connect the thermostat).

Although fuses at the input and outputs of the controller protect its circuits in case of an overload or overvoltage, we recommend installing an additional protection device on the supply circuit as well as an external relay on all ON-OFF stages to prolong the life of the controller.

The room temperature where the controller is located MUST

ALWAYS REMAIN BETWEEN 32°F AND 104°F (0°C TO 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

FOR CUSTOMER USE

Enter below the serial number located on the side of the controller and retain this information for future reference.

FEATURES

The ST 5129 is an electronic device used for environmental control in livestock buildings. It allows the user to maintain a specified target temperature by controlling the operation of ventilation and heating equipment. One stage of variable speed cooling fans can be connected to the controller, as well as nine stages of constant-speed fans and two stages of either constant-speed fans or heating units. In addition, the last cooling stage can be configured as a mist cooling stage.

The main features of the ST 5129 are as follows:

THREE-DIGIT DISPLAY

A three-digit display provides a high level of accuracy, allowing the user to specify a temperature to within one tenth of a degree (in Fahrenheit or Celsius units).

PILOT LIGHTS

Pilot lights indicating the state of outputs allow the user to monitor the operation of the system without having to enter the building.

MINIMUM VENTILATION CYCLE

When ventilation is not required for cooling, the first stage fans can be operated either continously or intermittently to reduce the level of humidity and supply oxygen to the room.

TEMPERATURE AND MINIMUM VENTILATION SPEED CURVES

The controller can be set to automatically change the temperature set point and the minimum ventilation speed over a given period of time in accordance with the user's requirements by specifying a temperature curve and a minimum ventilation speed curve with up to six different points each.

CHOICE OF FIVE MOTOR CURVES

The variation in motor speed resulting from a change in voltage will depend on the make and capacity of the motor. In order to achieve a high degree of compatibility between controller and motor, the user can choose from among five different motor curves, thus ensuring that the correct voltage is supplied.

QM1327.rev.02

ST 5129

FULL-SPEED FAN START-UP

In order to overcome the inertia of the ventilation system components and de-ice the fan blades in cold weather conditions, the controller supplies maximum voltage to the variable speed fans for 2 seconds immediately following each start-up.

FOUR INDEPENDENT TEMPERATURE PROBE INPUTS

Up to four temperature probes can be connected to the controller in order to obtain a more accurate reading of the average room temperature and a faster reaction time.

OVERLOAD AND OVERVOLTAGE PROTECTION

Fuses are installed at the input and outputs of the controller to protect its circuitry in the case of an overload or overvoltage.

COMPUTER CONTROL

The controller can be connected to a computer, thus making it possible to centralize the management of information and diversify control strategies.

CONTROL OF AIR INLET MOVEMENT

If the ST 5129 is used in combination with a SB 2000 controller, the movement of the air inlets can be coordinated with the operation of the fans using a potentiometer located on the curtain machine or baffle actuator. This allows the air inlets to be adjusted correctly, without the influence of uncontrollable factors such as wind or air from adjoining rooms. When tunnel ventilation is being used, the SB 2000 closes the air inlets.

OTOR TYPES

The relationship between the voltage supplied to a motor and its operating speed is described by a motor curve. This curve varies with the make and capacity of the motor. The various motors available in the industry have been divided into five categories and the controller has been programmed with a different motor curve for each of these categories. To ensure that the controller supplies the correct voltages, an appropriate curve must be selected for Stage 1 according to the type of fan motors used (see table on following page).

Selecting a Motor Type

Refer to the list of motors on the following page to determine which type number (1 to 5) is appropriate for the motors used.

n

INIMUM VENTILATION CYCLE

When the room temperature is below the set point, the Stage 1 fans operate according to the minimum ventilation cycle. Running the fans even though ventilation is not required for a cooling purpose is useful to reduce humidity levels and supply oxygen to the room. It also prevents the fans from freezing in winter.

INIMUM VENTILATION SPEED CURVE

The user can define a minimum ventilation speed curve to adjust the Stage

1 minimum speed automatically over a given time period. Each curve is defined by six points. Each point specifies a day number and a fan speed for that day. Once the points are defined, the minimum speed curve must be activated. When the minimum speed curve is activated, the controller adjusts the Stage 1 minimum speed every hour in a linear fashion between two consecutive points.

When the last point of the curve is reached, the curve is deactivated. The controller maintains the minimum speed specified for this point until the curve is reactivated or until a new single minimum speed is specified using the first method.

NOTE:

If the room temperature falls below the threshold value given in Table 1, the fans will begin to run at the minimum speed specified for the first point of the curve and will continue to do so as long as the room temperature remains below the set point. When the room temperature rises above the set point, the fans will return to the current minimum speed, calculated according to the minimum speed curve.

Interaction Between the Temperature Curve and the Minimum Speed Curve

•

The minimum speed curve can be activated only if the temperature curve is already activated

•

All points of the minimum speed curve other than the first one are automatically given day numbers identical to those specified for the temperature curve. Only the first point of the minimum speed curve has an adjustable day number. This day number must be greater or equal to the day number specified for the first point of the temperature curve and less than the day number specified for the second point of the temperature curve (see example 1).

If you activated the temperature curve six days ago, the current day number of the temperature curve is d11. Therefore, if you activate the minimum speed curve today, it will effectively be in operation the moment you activate it. In this case, the current minimum speed will be a value between 10% and 20%.

ZONED HEATERS

To configure your system for zoned heaters, set dipswitch # 5 to ON. Since the two heater outputs function independently, different probes are assigned to each output: Probes 1 & 2 are assigned to Heater A and Probes 3 & 4 are assigned to Heater B. Individual probes can be turned on or off using the push-button functions contained in the ROOM TEMPERATURE function (see section on Temperature Settings).

Note that the heaters can become active only if the average temperature from all activated probes is below the set point. If this isn't the case, the heaters will not turn on even if individual probe temperatures are below the set point (this condition applies only if both off temperatures are below the set point).

Ventilation problems can result if heating levels in the two zones are very different. This is because the fans are operated according to the average temperature from all zones. Suppose the animals are young and confined to one part of the building (zone 1) while the rest of the building is heated at a minimum level (zone 2). If the difference between the heating start temperatures is too great and zone 1 fans operate according to the average temperature for both zones, cooling in zone 1 may be insufficient. A built-in
