Simulation 
P980 Simulate 
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  current  output  will  change.  If  you  want  to  test  the  logic  of  the 
system that the relays are connected to then select a hard simulation, but if 
you don’t want 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. 
The choices for you to enter are as follows. 
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.
