CANCEL and test mode will end. 
When  in  manual  simulation,  by  default  test  mode  will  move the  level  by 
0.25m 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 0.25m and rate (P982) is  set to  1 min then the level will 
increase  or  decrease  at  a  rate  of  0.25m/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).  
LED’s 
There  are  two  LED’s  which  can  be  seen  through  the  lid,  of  the  blackbox 
enclosure, which will indicate the status of the relays whilst in simulation 
as follows:

Using the RS232 Serial Interface 
  
 
The  RS232  serial  interface  is  used  to  program  the  blackbox,  and  obtain 
information using a PC or other computer equipment. To do so, the settings 
for control are as follows: baud rate 19,200, 8 data bits, no parity, 1 stop 
bits. 
The  device  should  be  connected  to  the  RS232  Interface  via  the  RJ11 
connector as shown in Chapter 2 Installation.
