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 the 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 (P983) 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 ‘Simulation’. Simply change
the value of the parameter P980 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 (P981) will change this value.
In automatic mode, the rate at which the level moves up and down is set by
the increment (P981 in metres, and the rate (P982) in minutes, which can be
changed to make the level move up and down faster. E.g. if increment
(P981) is set for 0.1m and rate (P982) is set to 1 min then the level will
increase or decrease at a rate of 0.1m/min. To make the simulated level
move slower, decrease the value in increment (P981) or increase the value
in rate (P982). To make the simulated level move faster, increase the value in
increment (P981) or decrease the value in rate (P982).
