Check System Parameters — To check system parameters, press the STAT button. The LID display will show: “Hardware Points Table 1.” Press ENTER to view the hardware points. The user can navigate up and down through the points with the up and down arrows.

Press 2 and STAT to display the software points. The user can navigate up and down through the points with the up and down arrows.

Refer to Tables 8 and 9 for hardware and software points.

Display Alarm History — If the controller is indicating there are alarms, the user can view the alarm history by

pressing the HIST button. The LID display will show “Alarm

History.” Press ENTER . The LID display will show the date

and type of alarm.

As an example, if the LID display shows: ALARM — 10:55 11-27-02

SFS

That display indicates that on 11/27/02 at 10:55 A.M. the system Supply Fan was either on when it had not been commanded on or was off when it was commanded on.

The user can view other stored alarms by pressing the up and down arrows. The twenty-four most recent alarms are stored.

Configure Custom Programming Selections —

To configure the custom programming selections, perform the following procedure:

1.Press 37 ALGO . The LID display will show: Custom Program

2.Press ENTER . The LID display will show: 2.0 Global Dictionary

OMNIZONE

3.Press ENTER . The display indicates “No Data.” Press CLEAR then press EXPN/EDIT . Press ENTER again. The LID display should now show:

Compressor Stages 4.00

4.Press 4 and then ENTER to indicate that 4 compressors are installed.

5.Use the down and up arrows to select the other configura- tion parameters as required. See Table 10 for a list of con- figuration parameters.

6.A field-supplied 0 to 10 vdc signal to the 50XJ unit may be used to reset the supply-air temperature.

The reset will be taken off the supply air set point configured in the controller. The reset range can be changed by adjusting the High Conversion Endpoint value of the custom voltage input to a value other than 20. For example for 10 degrees of reset change the Hi input value to 10. This may be found by pressing 7 STAT from the Keypad. RESET will be the second custom voltage input point in the controller. The first will be CSMUX, which is the compressor status multi-

plexed input. Press to see the following in the LID display:

Ext. Supply Air Reset

RESET

Press ENTER . If the LID display shows:

System Value

Press EXPN/EDIT . The LID display will show:

Low Input Endpoint 2.0 Volts

Press three times to get to the High Conversion Endpoint. The user must be logged in to be able to change this otherwise you can only view it. See the start up section for how to log into the controller.

Configuration parameters are shown in Table 10.
