7. 4 How to vary parameters
Blocksystem operation is governed by parameters that have been stored in the memory of the electronic
control unit by the manufacturer (see the parameters table). These factory settings should not be varied
unless strictly necessary and in all cases, such operations are only to be carried out by qualified staff.
Parameters are not only divided by function, they are also divided according to their security/accessibility
levels:
level 0
UK
level 1
Parameters can be varied as follows:
from the keyboard
via LAN network (Master/Slave)
via Supervision network
7. 5 How to vary level 1 parameters
hold down SET for 5 seconds until the display reads "reg" (adjustment parameters)
press UP or DOWN until the required menu appears on the display
press SET to access the menu; the code number for the first parameter in the selected menu will
appear
press UP or DOWN until the required parameter appears
press SET to view the value of the parameter
press UP or DOWN to set the required value
press SET to confirm the value and return to the parameters list; press ON/OFF to confirm the
value and return to the menu list
press ON/OFF to pass from the parameters list to the menu list
press ON/OFF again to exit the editing procedure,
If no key is pressed for more than 15 seconds, any value shown on the display will be stored in the
memory for the relevant parameter and there will be a forced exit from the parameters variation
procedure.
