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 outputs will
change in accordance with 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 don’t wish to change the relay state, then select a soft simulation.
There are two simulation modes for each point of measurement, automatic and
manual. Automatic simulation will move the level up and down between empty
level or the pre-determined Start Level (P983) and the span, if you wish to change
the direction of the level movement, this can be done by using the left/right arrow
keys. In manual simulation, using the up/down 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’. Select the point of measure
you wish to simulate and press enter to access the simulation options. You can
change the value of the parameter to one of the following:
1= Manual soft simulation
2= Automatic soft simulation
3= Manual hard simulation
4= Automatic hard simulation
When in test mode, the display will show the graphical level indicator with the
current mode of operation value in measurement units. Also shown will be the
relay setpoint indicators, for each relay, with an arrow showing the current level
relevant to that relay allocation e.g. if you are simulating point 1 then the level
indicator will move up and down along with the arrows next to any relay allocated
to point 1. If a relay is allocated to sum, average or differential, then the Sludge
Finder 2 will span the relay diagram to the sum, average or differential of point 1
and 2. The level of point 2 (or point 1 if simulating point 2) will always remain at
0.
To return to program mode, press CANCEL and test mode will end.
