Once a parameter has been changed, press
‘
ENTER
’
and you will see the
message
“
Saved!
”. If you press ‘
CANCEL
’
, then the change you made will not
be saved, and the message “
Unchanged!!
” will be displayed.
You can jump straight to the last parameter you edited, by pressing
‘+/
-
’
when you first enter program mode.
Test Mode
Test mode is used to simulate the application and confirm that all
parameters and relay setpoints have been entered as expected. During
simulation, there is a choice of whether the relays will change state (hard
simulation) or not (soft simulation), but th
e LED’s will always change colour
as programmed, and the mA output will change in accordance to the chosen
mode of operation. If you wish to test the logic of the system that the
relays
are connected
to then select
hard simulation
, but if you
do not wish to
change the relay state
, then select a
soft simulation
.
There are two simulation modes, automatic and manual. Automatic
simulation will move the level up and down between empty level or the pre-
determined
Start Level (P*983)
and Pump/Control relay switch points, if
you wish to change the direction of the level movement e.g., to go beyond
relay setpoints, this can be done by using the arrow keys. In manual
simulation, using the arrow keys will allow you to move the level up and
down as required.
To enter simulation, first go to program mode. Using the menu system,
select menu item ‘
Test
’, then sub
-
menu item ‘
P1
or
P2
Simulation
’. Simply
change the value of the parameter
P*980
to one of the following:
1= Manual soft simulation
2= Automatic soft simulation
3= Manual hard simulation
4= Automatic hard simulation
To return to program mode, press
‘
CANCEL
’
and test mode will end.
When in manual
simulation, by default test mode will move the level by
0.1m steps. Altering the
increment
(
P*981
) will change this value.
