8. To write this new setting to the controller’s database, press the key once. The
new setting will be saved and dEC.PdEC.P (decimal position) will be displayed on the lower
line. (The blanking parameter is the last in the display menu, so the controller goes
to the top of the menu and shows you the first display parameter, decimal position.)
9. Because you do not plan to change any other display parameters at the present time,
press the key to go to the next menu OutPOutP (output).
10. Because you do not plan to change any output parameters during this configuration
session, press the key again. The name of the next menu in the cycle CtrLCtrL
(control) will be displayed.
11. You do not need to change any control parameters right now, so press the key
again. The top line will show AlrAlr (alarm).
12. Because the alarm 2 setpoint that you want to change is on the alarm menu, press
the key to display the first parameter in the alarm menu. This is A1.AAA1.AA (alarm 1
alarm action).
13. Press the key repeatedly until you see the parameter that you want to change:
A2.SPA2.SP (alarm 2 setpoint). The current value will alternate with the A2.SPA2.SP label.
14. Use the and keys to change the alarm 2 setpoint to the new value.
15. Press the key once to save the change. Because the A2.SPA2.SP parameter is at the
end of the menu, the first parameter in the alarm menu will be displayed again.
16. The two changes you wanted to make have been accomplished, so you can press
and hold the key to return to the normal operating display.
If you do not press and hold the key, after a brief interval the controller will
automatically go back to the normal operating display (PV and SV).
If you do not press the key after you change a parameter value, and you are
subsequently timed out of the menu system, the change will not be saved to the
controller’s database.
