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 SS 5126A 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, one stage of constant-speed cooling fans, as well as curtains, foggers, heaters and up to 6 tunnel stages can be connected to the controller.

The main features of the SS 5126A 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.

ZONED OR STAGED HEATERS

QM 1314.rev.05

SS 5126A

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.

OUTSIDE TEMPERATURE PROBE

Used to prevent curtains opening when the outside temperature is too low or activate tunnel mode when outside temperature is too high.

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 USING THE SB 2000

If the SS 5126A is used in combination with a SB 2000 controller, the movement of the air inlets can be coordinated with the operation of the stage 1 and 2 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.

NOTE: After programming the reference points for stage 2, press and hold the push-button for two seconds to end the programming sequence.

OTOR CURVES

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 Curve

Refer to the list of motors enclosed with this user's manual to determine which curve number (1 to 5) is appropriate for the type of motors used.

n

EMPERATURE PROBES

1

Connecting the Probes

The controller is supplied with one room probe connected to input # 1 and one outside probe connected to input # 5. Three additional probes can be connected to inputs # 2, # 3 and # 4. If zoned heating is used, Heater A uses probe 1 and Heater B uses probe 2. If cascading heating is used, the average temperature from selected probes # 1, 2, 3 and 4 is used.

CAUTION

:

Probes operate at low voltage and are isolated from the supply. Be sure that probe cables remain insulated from all high voltage sources. In particular, do not route the probe cables through the same electrical knockout as other cables. Do not connect the shield from the probe cable to an input or a ground.

2

Extending the Probes

Each probe can be extended up to 500 feet (150 meters). To extend a probe: n

Use a shielded cable of outside diameter between 0.245 and 0.260 in

(6.22 and 6.60 mm) (the cable dimensions should not be under 18

AWG) to ensure the cable entry is liquid tight. Do not ground the shielding.

n

It is preferable to solder the cable joint to ensure a proper contact between the two cables.

CAUTION:

Do not run probe cables next to other power cables. When crossing over other cables, cross at 90°.

QM 1314.rev.05

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 yesterday, the current day number of the temperature curve is d6. Therefore, if you activate the minimum speed curve today, it will effectively be in operation in 4 days, when the current day number of the temperature curve reaches d10.

In the meantime, the fans will run at the specified single minimum speed (see example 2).

•

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%.

URTAIN SETUP

To position the curtains for tunnel ventilation, the controller fully closes the sidewall curtains and fully opens the endwall curtains. This is refered to as doing the curtain setup. Either one of the curtains may already be in the required position, depending on when the setup is done.

The curtain setup is done when the following conditions are met:

EITHER Room Temperature >= Stage 6 Starting Temperature

OR Room Temperature >= Stage 4 Starting Temperature

AND

Outside Temperature >= High Outside Temperature Limit

When these conditions are met, the controller waits a user-specified delay called the In Tunnel Delay before going into the tunnel ventilation mode.

During this delay, the curtains are set up. All other stages are inactive except Stages 1 and 2.

After the delay has elapsed, the cooling stages operate according to the room temperature as shown in the following diagram except for Stage 4 which is always in operation. (The diagram assumes that stages 8 and 9 are used for cooling). Note that internal switch #6 must be set to OFF to use

Stage 7 for tunnel ventilation (Stage 3 is no longer available for normal cooling purposes when this is done).

The curtain setup is undone when the following conditions are met:

Room Temperature <= Stage 6 Stop Temperature

AND

Outside Temperature <= High Outside Temperature Limit - 3 o

F

When these conditions are met, the controller undoes the curtain setup in two phases lasting 240 seconds in all. In the first phase, the controller fully opens the sidewall and endwall curtains. All stages are inactive except

Stage 4. The duration of this phase is determined by a user-specified delay

SS 5126A called the Out Tunnel Delay . In the second phase, Stage 1 fans operate at full-speed and Stage 2 fans operate normally. If the curtains are not yet fully open, they continue opening. All other stages are inactive. The duration of this phase is the time remaining after the out tunnel delay has been subtracted from the total duration of 240 seconds.

After the delay has elapsed, the cooling stages operate according to the room temperature as shown in the preceding diagram. The table below summarizes stage operations going into and coming out of tunnel ventilation mode.

ALARM SETTINGS

The controller sets off an alarm in the case of a power failure, a fault in the supply circuit or a high or low temperature. Temperature alarms are defined according to the set point as shown in the diagram below.

Room

Temperature

High Temperature Alarm

High Alarm Temperature

Set Point

Low Alarm Temperature

Time

The situation changes for high temperature alarms, however, when the outside temperature is greater than the set point. In this case, the set point is replaced by the outside temperature as the reference point. This means an alarm is set off when the indoor temperature reaches Outside

Temperature + High Alarm Offset. A third parameter, called the absolute high temperature, is defined to continue monitoring the indoor temperature for high temperatures. When the indoor temperature reaches the absolute high temperature, an alarm is set off.

1

Adjusting the Alarm Settings

The high and low alarm settings are specified as a temperature value. The high alarm temperature ranges from set point + 0.5°F to set point + 40°F. The low alarm temperature ranges from set point - 40°F to set point - 0.5°F. The absolute high temperature ranges from

–40°F to 120°F.
