7.Press ENTER to register the values and to move hori- zontally (left to right) within a period.

8.Press EXIT to leave the period or override.

9.Either return to Step 4 to select another period or over- ride, or press EXIT again to leave the current time schedule screen and save the changes.

10.The Holiday Designation (HOLIDEF table) may be found in the Service Operation section, page 45. The month, day, and duration for the holiday must be assigned. The Broadcast function in the BRODEF table also must be enabled for holiday periods to function.

TO VIEW AND CHANGE SET POINTS (Fig. 20)

1.To view the SETPOINT table, from the MENU screen press SETPOINT .

			19XR_II			SETPOINT		SETPOINT SELECT
			Base Demand Limit					100%
			Control Point
			LCW Setpoint							50.0 F
			ECW Setpoint							60.0 F
			ICE BUILD Setpoint							40.0 F
			Tower Fan High Setpoint							85.0 F

Fig. 20 — Example of Set Point Screen

2.There are 5 set points on this screen: BASE DEMAND LIMIT, LCW SETPOINT (leaving chilled water set point), ECW SETPOINT (entering chilled water set point), ICE BUILD SETPOINT, and TOWER FAN HIGH SETPOINT. Only one of the chilled water set points can be active at one time. The set point that is active is determined from the SERVICE menu. See the Service Operation section, page 45. The ice build (ICE BUILD) function is also activated and configured from the SERVICE menu.

3.Press NEXT or PREVIOUS to highlight the desired set point entry.

4.Press SELECT to modify the highlighted set point.

5.Press INCREASE or DECREASE to change the select- ed set point value.

6.Press ENTER to save the changes and return to the pre- vious screen.

SERVICE OPERATION — To view the menu-driven pro- grams available for Service Operation, see Service Operation section, page 45. For examples of CVC/ICVC display screens, see Table 2.

The two passwords protecting the VFD configuration are Parameter Set Display password and Program Disable password. The Parameter Set Display password restricts view- ing. P.nnn parameters above 007 and all H.nnn and R.nnn screens. The password can be accessed at parameter P.006 and will switch between enabled and disabled each time the pass- word 107 is entered. The Program Disable password restricts the changing of the drive parameter set.
