Keyboard Lock; Machine Status Menu - Eliwell IWP750 Anleitung

The controller keyboard can be disabled in 2 ways:
• By pressing a sequence of keys: UP+ ESC for 2 seconds, repeat to unlock the keyboard.
• By programming paramter LOC appropriately (see folder with label diS).
NOTES: - To show that the keyboard has been locked, the LED on the right of the SET key lights up.
- When the keyboard has been locked, the programming menu can always be accessed by pressing the SET key for at least 5 seconds.
The setpoint can still be viewed.
To manually activate the defrost cycle, hold down the UP key for at least 2 seconds, or activate it from Digital Input.
If conditions for defrosting are not present, i.e. if:
•
Evaporator probe Pb2 temperature is greater than the end defrost temperature (valid if H42 = y).
•
Parametro OdO = 0
The display will blink three (3) times to indicate that the operation will not be performed.
The copy card is an accessory which, when connected to the TTL type serial port, allows quick programming of the instrument parameters (upload
and download of a parameter map to or from one or more instruments of the same type). The operations are performed as follows:
Fr (Format)
This command is used to format the copy card, an operation which is necessary when the instrument is being used for the first time or with other
models which are not mutually compatible.
IMPORTANT: when the key has been programmed, all data entered will be deleted when parameter Fr is used. This operation cannot be reversed.

DOWNLOAD

The operations are carried out by accessing the folder identified by the label "FPr" and selecting the commands "UL", "dL" or "Fr" as required.
Press the "SET" key to confirm this operation.
If the operation has been successfully completed, the "y" label will appear, otherwise the "n" label will appear.
Download "from reset"
Connect the Copy Card with the device OFF. On switching the controller on, the programming parameters will be loaded from the key; on
completion of the lamp test, the display will show the following for 5 seconds:
• label dLY if the operation completed successfully.
• label dLn if the operation failed.
NOTE: After the parameters have been downloaded, the device uses the new map just downloaded.
The instrument has two main menus which can be accessed as follows:
• "Machine Status Menu": press SET key once.
• "Programing Menu": press and hold the SET key.
Press the "set" key once to view the contents of any folder highlighted by the corresponding label.
At this point it will be possible to scroll through the contents of the folder and make changes or use the functions contained therein.
Either press no key for 15 seconds (time-out) or press the "ESC" key once to confirm the last value displayed and go back to the previous screen.
Press and release the SET key to open the "Machine Status" menu. The following parameters will appear:
• AL: alarms folder (if present; probe errors/faults excluded).
• SET: Setpoint configuration folder.
• Pb1: probe 1 value folder.
• Pb2: probe 2 value folder.
You can use the "UP" and "DOWN" keys to scroll through all folders in the menu.
