8.5 Parameter setting
During parameter setting the unit remains in the operation mode.
It continues to execute its monitoring functions with the existing parameters until
the parameter setting is completed.
The following has to be taken into account for parameterizing:
First, select the correct valve size by means of the rotary coding switch. As soon as
the position of the rotary coding switch is changed, test jack “v“ outputs the valve
size in the form of the corresponding voltage in Volt [0.1 V/valve size].
Valve no. 5, for example, has a voltage of 0.5 V.
As soon as a valve size was correctly accepted (by pressing Set > 1 s), the internal
command value is again signaled at test jack “v“.
To have the valve size shown again at test jack “v” for 5 s, press “-“ once.
Press[Set] > 1 s in order to switch to the first settable parameter (simple ramp,
see Abb. 5).
1. Press [Set] to edit the selected parameter.
2. Press [+] or [-] to change the set value.
Set values can be checked with the help of a multimeter. Every set value stands
for a voltage output or a percentage value at the connected multimeter. The
assignments are listed in the tables in chapters 8.5. and 8.5.2 (output at test
jack).
If, while a parameter is set, no key is pressed for 10 minutes , the amplifier
returns to normal operation without saving the newly set value.
Press [Set] to exit the editable parameter. The set parameters are thus saved.
Press [+] or [-] until the relevant parameter is displayed.
To switch to the “Expert Mode“ you have to be in the “Standard Mode“: Press
[-] and [Set] simultaneously. In the “Expert Mode”, the general parameter setting
procedure corresponds to the menu level “Standard Mode“.
To exit the “Expert Mode“, press [Set] (> 1 s).
The device is again in the operation mode.
Press [Set] (> 1 s).
The device is again in the operation mode.
