Operation with Advanced Microprocessor with Graphics Control

3.8.4DIP Switches

The DIP switch settings can be reviewed from the display panel. Changing the DIP switches requires opening the front panel for access to the DIP switches on the microprocessor control board.

NOTE

Power MUST be cycled off, then on, from the unit disconnect switch for the control system to update the DIP switch settings (except for switch 8).

These selections should match options installed on your unit and should not need to change during normal operation. Switches 1 through 7 are self explanatory. DIP switch 8, not shown in Table 11, below, enables the password feature when set to ON and disables the password feature if set to OFF.

3.9Date and Time

The current date and time is available through the display. This feature allows the date and time to be read or changed and is accessed by selecting “DATE AND TIME” from the Main Menu. The “DATE AND TIME” is used by the control for recording the Alarm History and plotting graphs.

NOTE

The clock uses the 24 hour system (For example: 17:00 would be 5:00 PM). The date and time are backed up by battery.

3.10Plot Graphs

Selecting PLOT GRAPHS will step to the following menu:

TEMPERATURE PLOT

HUMIDITY PLOT

ANALOG SENSOR #1 PLOT

ANALOG SENSOR #2 PLOT

ANALOG SENSOR #3 PLOT

ANALOG SENSOR #4 PLOT

MODIFY PLOT SCALES

Six different data types are recorded for graphing: temperature, humidity, and four user defined ana- log inputs. Each data type can be viewed over three different time scales and two different resolu- tions. The three time scales are 90 minutes, 8 hours, and 24 hours. The two resolutions are minimum and maximum. With minimum resolution selected, the full scale of the sensor is displayed. In other words, the largest and smallest possible sensor readings are shown. Maximum resolution shows a range that covers two-fifths of the full scale sensor range.

3.10.1Modify Plot Scales

The MODIFY PLOT SCALES menu item adjusts the layout of the graph. This setup screen selects the time scale and resolution. It also adjusts the center of the graph for a maximum resolution graph.

The time scale and resolution can also be changed while the graph is displayed. The DOWN arrow key changes the time scale from 90 minutes, to 8 hours, to 24 hours. The UP arrow key toggles the display between maximum and minimum resolution.
