This function allows you to replace the factory codes ("111" for level 1,
"222" for level 2) to be replaced by your own. If the value "000" is now
entered for a code, code locking is cancelled and access to the
corresponding operator control level is now unrestricted.
The following three tests will allow you to test the functional serviceability
of the unit.
•
Keyboard test:
With the keyboard test all of the keys on the control panel can be
tested.
With the five soft keys on the right-hand edge the corresponding
item can be made to appear or disappear. If a number key or sign
key is pressed, the corresponding number will be displayed in the
editing field on the bottom line of the screen.
Pressing the "INFO" key will issue a plain-text message; here the
"MEAS" and "ESC" retain their return functions.
•
Relay and binary-input test
The first screen shot shows the status of the six relay and binary
inputs in a standard unit. If an option board is fitted, on a second
screen page a further eight relays or binary inputs will be found.With
the relay test individual relays can be activated. This is done via the
input field. With a "1" the relay picks up, with a "0" it returns to its
release state. The input field will not allow you to input anything
except "0" and "0."
After you quit function 80 the relays will have the status which they
had before the relay and binary inputs test was selected.
The current state of the binary inputs is shown in the "Binary"
column.
• Analog test
With the analog test the analog output can be set for testing
purposes to a constant current of between 0 and 24000 µA.
The analog input shows the current input currents in µA.
