Relative centrifugal force (RCF) and centrifuging radius (RAD)

Relative centrifugal force (RCF) depends on the centrifugal radius (RAD). Before RCF is set, the centrifugal
radius has to be set.

Press the key as often as is required until the parameters RAD and RCF are displayed and the value of
RCF
the parameter, RAD is displayed in parentheses,  e.g. RAD = 146

Use the adjusting knob
By changing the centrifuging radius, the value adjusts automatically to the RCF.
 key again. The value of the parameter, RCF is displayed in  parentheses, e.g. RAD = 146
Press the

RCF = 3695.

Press the key to save the set RCF value. See the "Inputting or changing programs" chapter.

Press the or
RCF START
Only by storing (STO) the set RCF value will the RPM value resulting from that be accepted.

Start-up and run-down parameters

The set start-up and run-down parameters are displayed.
x: 1-9 = start-up stage, t = start-up time
y: 1-9 = braking stage, 0 = unbraked run-down, t = run-down time

Start-up stage and start-up time

It is only possible to set start-up times if these have been activated. See the chapter "Activating or deactivating
start-up and run-down times".

Press the key. The parameter
= start-up stage, t = start-up time
Press the key to switch between the start-up stage and start-up time.

15.5.2

Braking stage and run-down time

No B-brake stages can be set for this device. The activation of the B-brake stages in the "Settings" menu is
not possible (parameter B-Ramp = off). B-brake stages are similar to an exponential braking curve.
It is only possible to set run-down times if these have been activated. See the chapter "Activating or
deactivating start-up and run-down times".

Press the key until the parameter
= braking stage, = run-down time
