6 Setting the Rotational Speed Monitoring Device JMNC
Attention!
Only switch on the rotational speed monitor-
ing device together with the drive.
Only set the device with corresponding oper-
ating temperature in order to reach the high-
est accuracy when setting the switching
point.
When using the included setting tools (
22
) they
are latched and hard to pull off again. We there-
fore recommend you to leave the setting tools
(

) in order to prevent maladjustment of the po-
tentiometers when pulling the tools off.
It is also possible to use a screw driver with an
insulated shoe.
