Parker LevelController SCLSD User Manual

3. Operation modes
The level switch has the following operating modes:
 Run mode
(normal working operations)
 Display mode
(display of set parameters such as switching points,
opener, closer...)
 Programming mode
(setting of parameters such as switching points, opener,
closer...)
 Reset mode
(resetting to standard values)
Switching on
When the supply voltage is switched on, the level switch
carries out a self-test.
 The display and the switching point indication light up.
 The length of the sensor is displayed.
During this time (2 secs.) the outputs are not active.
Run mode
After switching on, the level switch is in run mode.
The digital display indicates the actual level and the two yellow
LED´s signal the actual switch status of the outputs. It carries
out its monitoring functions, switches the switch outputs in
accordance with the set parameters and converts the actual
system temperature into an analogue signal.
Display mode
In the display mode the control parameters can be shown but
cannot be changed.
To ensure trouble-free operation, the level switch remains
internally in the run mode. If no key has been pressed for
60 seconds, the level switch changes back automatically
to run mode.
Display mode activation is by the Enter key
.
The letters diSP appear.
 A short touch on an arrow key
or scrolls through
the menu points.
 A short touch on the Enter key
shows the relevant
parameters.
 A password is shown as - - - - .
Programming mode
In the programming mode the parameters are changed and
stored thereafter continuously. An electrical supply is not
necessary for the retention of stored data (storage in EEProm).
To ensure trouble-free operation, the level switch remains
internally in the run mode. If no key has been pressed for
60 seconds, the level switch changes back automatically
to run mode.
Activation of the programming mode
To exclude the unintentional change of programmed
parameters, the programming mode can be activated only
by the following key combinations:
 Press an arrow key
or and keep it depressed.
Whilst holding an arrow key depressed, press
the Enter key
.
The letters
ProG appear.
Password protection
To prevent any unauthorised change of parameters,
the programming mode can be protected by an optional
pass word.
 When a password has been programmed in, PAS
appears. With the arrow key
or the password is
entered and confi rmed with Enter
. After this the level
switch can be programmed.
 No password has been set up (password = 0000),
the level switch can be immediately programmed.
Programming
 Press an arrow key or to scroll through
the menu points.
 Pressing Enter
shows the relevant parameters.
 Pressing the arrow keys
or changes the selected
parameters. Holding the arrow key depressed achieves
fast and easy input and the values of the parameters to
be set can be changed faster.
 A changed value is confi rmed/ saved with the Enter
key
and the next menu point is then displayed.
The level switch carries on with its monitoring functions
to the existing parameters until the respective change is
concluded.
Reset mode
When the supply voltage is switched on
the two arrow keys
are pressed simultaneously.
The letters
rSt appear.
When both arrow keys
are kept depressed and the
Enter key
activated, the level switch resets all the settable
parameters back to the factory settings.
