FaN FaIlURe

This alarm activates on the incubator when any one of

the Motor Off sail switches is not being pulled toward the fans (the fan motor may have prematurely stopped), or on the hatcher, when the current of one of the fan

motors is below the minimum threshold.

MaINteNaNCe

This alarm activates in:

Hatchers when the Fan switch is turned off.

Incubators when the Fan switch on the control box or at the entrance end is turned off. When the entrance

Fan switch is turned off, all alarms will be silenced for up to five (5) minutes or until fans are turned back on.

tURN FaIlURe

This alarm (incubators) activates if any one rack does not completed turning within five (5) minutes after the turn solenoid has changed state. This alarm can be cleared by pressing the Alarm Acknowledge button. If a rack does not complete a turn but then turns successfully in the other direction, the Egg Turn alarm will end.

NOte: When the turn solenoid is off, the racks

must turn to right side and when solenoid is on, the racks must turn to left side, otherwise a Turn Failure alarm occurs on every turn.

DOOR OPeN

This alarm (hatchers) – under normal operating condi- tions, the alarm activates whenever one of the doors is opened.

SySteM StatUS

The System Status indicators (LEDs) are located ad- jacent to the System Status icons. Each System Status LED will illuminate when its output function is in use. In some instances, System Status indicators differ between incubators and hatchers. They are noted below.

MaIN heateR (INCUBATORS)

OR heateR (HATCHERS)

When the temperature is 0.2°F (0.11°C) or more below setpoint, the incubator main heater or the hatcher heater turns on.

aUxIlIaRy heateR (INCUBATORS)

When the temperature is 0.4°F (0.22°C) or more below setpoint, the incubator auxiliary heater turns on.

COOlING (INCUBATORS)

When the temperature is 0.1°F (0.05°C) or more above setpoint, cooling solenoid turns on (if equipped).

PRIMaRy COOlING

(CHICKEN HATCHERS)

When the temperature is 0.2°F (0.11°C) or more above setpoint, a signal is sent to the blower on the 2-Door Hatcher, or the one inch air solenoid on the PX Hatcher. (The primary cooling device for the 2-Door Hatcher is the blower while the primary cooling device for the PX Hatcher is the primary air valve and one inch solenoid.) Primary cooling is not used on turkey hatchers.

SeCONDaRy COOlING (HATCHERS)

When the temperature is 0.4°F (0.22°C) or more above setpoint, a signal is sent to the auxiliary blower on the 2-Door Hatcher, or the two inch air solenoid on the PX Hatcher. (The secondary cooling device for the 2-Door Hatcher is the auxiliary blower while the secondary cooling device for the PX Hatcher is the secondary air valve and two inch solenoid.)

SPRay

When the actual humidity is within 1.5°F (0.83°C) of setpoint (incubators) and within 0.5°F (0.27°C) of setpoint (hatchers), the spray turns on and will then cycle on and off. When the actual humidity is below these thresholds, the spray will remain continuously on.

DaMPeR ClOSe

When the temperature is 0.1°F (0.05°C) or more below setpoint (all incubators and chicken hatchers), or 0.2°F (0.11°C) below setpoint (turkey hatcher), the damper will close. The damper will stop closing when it has reached the fully closed position.

DaMPeR OPeN

When the temperature is 0.1°F (0.05°C) or more above setpoint the damper will open. The damper will stop opening when it has reached the fully open position.

DaMPeR FUlly ClOSeD

When the damper is now in the fully closed position. The damper will stop closing but is still allowed to open.

DaMPeR FUlly OPeN

When the damper is now in the fully open position. The damper will stop opening but is still allowed to close. Each System Status LED will illuminate when its output function is in use - Primary Heat Status illustrated.

tURN valve (INCUBATORS)

The turn valve indicator shows whether the air solenoid on or off. Racks turn to right when solenoid is off, and turn left when solenoid is on.

all RaCkS leFt

The left turn indicator (incubators) lights up once all racks have turned to the left side. It will remain on as long as the egg trays are all in the left position. Should one rack fail to complete a turn sequence, this LED will remain off. After a period of five (5) minutes, the Turn Failure alarm will activate.

all RaCkS RIGht

The right turn indicator (incubators) lights up once all racks have turned to the right side. It will remain on as long as the egg trays are all in the right position. Should one rack fail to complete a turn sequence, this LED will remain off. After a period of five (5) minutes, the Turn Failure alarm will activate.

tURN IN PROGReSS

In the incubator, the Racks Turning indicator lights up while racks are in the process of turning or if any of the turn cables have not been hooked up. If one rack fails to turn properly, this LED will remain on. If the racks then successfully turn in the other direction, this LED will turn off.

Note: The alarm indicator lights for All Racks

Left, All Racks Right and Turn in Progress will not illuminate if the Machine Type DIP switch is set for No Turn Alarm. Therefore, in incubators not equipped with a turn sensing system, set the DIP Switch setting for Egg Turn to the No Turn Alarm mode. The Egg Turn LEDs will then remain off.

If there is an audible alarm, press the button to temporarily silence any alarm. Acknowledging the alarm will not cancel the alarm. (See Exceptions below.) The cause of the alarm must be corrected. Therefore, any of the following conditions may occur.

• If there is an active audible alarm, the Common

Alarm lamp will blink rapidly.

• If there is an active inaudible alarm, the Common

Alarm lamp will blink slowly.

• If there is no other active alarm, the Common

Alarm lamp will extinguish.

• Any alarm which are no longer active but whose indicator (LED) is still lit, to show past activity, will be cleared.

• If an alarm is still active after the Silence Delay interval has past, the alarm relay will reactivate. This time delay can be programmed using the Alarm Silence Delay function. Refer to page 28. • If a new alarm becomes active, the audible alarm,

alarm indicator (LED) and Common Alarm lamp will reactivate immediately. (Refer to Common Alarm Lamp on page 20.)

FUNCtION BUttON

The PS501 Controller is equipped with one Function button, which is used to calibrate the temperature readout, calibrate the humidity readout, set the tem- perature units, set the alarm silence delay and set the rack turn interval.

All operations must be completed within thirty (30) seconds, or else the display automatically changes back to the normal temperature and humidity display. You may notice error messages such as Err or Loc

appear as you attempt to key in your changes. Refer to Error Messages on page 72.

OR

teMPeRatURe aND hUMIDIty CalIBRatION

The calibration function is used to adjust the sensor temperature if the Actual Temperature or Actual Humidity reading does not agree with the secondary measuring device such as a mercury thermometer or an electrotherm.

The temperature offset is the correction factor and is displayed in the Humidity Setpoint box. It is shown in degrees Fahrenheit or Celsius depending on the cur- rent temperature preference selection. The offset can be either positive or negative.

Machine Sensor

Reading +/- Offset = Corrected actual Reading For detailed instructions on calibrating the sensor, refer to page 30.

teMPeRatURe UNItS

You may display the temperature units in degrees Fahrenheit or Celsius. The units you choose will also be used for humidity wet bulb readings.

Note: The machine is controlled in degrees

Fahrenheit no matter which units you choose to display. If you select Celsius for your read- ings, you may notice that the machine appears not to be controlled to the correct setpoint. This is due to a slight conversion error as the machine’s actual reading (in Fahrenheit) is converted to Celsius.

Changing the temperature Readout Units

1. Press the button, the temperature setpoint area will show Fn.

2. Press the 3 button, the temperature setpoint area

will show Fn3, and the humidity setpoint area

The PS501 Multi-Stage control system requires routine

maintenance. Many potential problems can be elimi- nated by following these simple procedures. Generally, system maintenance can be accomplished as part of your downtime during cleaning operations.

Warning: Jamesway recommends that only

qualified electrical personnel service the ma- chines. Some circuits are energized with 220 volts. They will cause serious shocks, injury or death if touched. Before starting mainte- nance, ensure that the Main switch is turned

to Off (0) and the power is locked out at the

distribution panel.

CONtROl BOx

Inspect the hatcher control box once a week, and the incubator control box once a month.

PROCeDURe

Turn the fans off. Turn the Main switch off and ensure the power is locked out at the distribution panel. Check for a build-up of chick down, dust or metal shavings. An excessive build-up of chick down will cause moisture to collect. Moisture may in turn cause the system to short circuit. Carefully vacuum the inside of the control box. It is not recommended that an air hose be used for this procedure.

Examine the boards, wiring, connections and relay contacts for obvious faults such as discolouration and burned or blackened areas. Pay special attention to terminals, connections and relay points.

Once maintenance is complete, and the interior of the control box is thoroughly dry, replace the control box lid. It is absolutely essential that this lid be in place and locked at all times.

Turn the power back on. Turn the fans back on.
