The Set Point value can be adjusted locally using LCD/keypad, remotely via RS-
232/RS-485 digital interface or can be programmed in advance using user-preset
programs of up to sixteen steps (Program Set Point Mode).
a) Adjusting Set Point value using local LCD/keypad
Current Set Point value is displayed on the second line of the main PI screen, next
to the ‘S’ character.
Pressing the
ENT
button while in the main PI screen will activate Set Point adjust-
ment mode. The first character of the Set Point value will start to flash. Use
UP
or
DN
button to increment / decrement digit value from 0-9. Use
RIGHT
or
LEFT
but-
ton to move cursor to another digit position. When desired Set Point value is
entered use the
ENT
button to accept (save in the EEPROM) new Set Point value.
If at the end of the Set Point value entry the
ESC
button is pressed instead
ENT
,
the original Set Point value will be restored and Set Point adjustment mode will be
deactivated. To exit from the Set Point adjustment mode before Set Point value is
accepted, press the
ESC
button.
b) Controlling Set Point value using Program Set Point mode
To activate Program Set Point mode the following must to be done:
1. Program Set Point mode must be Enabled (see paragraph 5.3.16 a).
2. Program Loop parameter must be set to desired value (On/Off).
3. Program Run parameter must be set to “On” (default settings is Off).
NOTE: Since the Set Point value entered via local LCD/keypad is
stored in the non-volatile memory (EEPROM), it will be executed on
the next device power up event.
,
NOTE: If the Program Set Point mode is enabled and the program is
running, the Set Point value can be changed at any moment by the
execution of the next active step. The Set Point entered via local
LCD/keypad can be also changed via digital RS-232/RS-485 interface.
