Magtrol WB/PB DynamometersChapter 2 – Installation / Mounting
2.1.5 WB/PB 15 SerieS
WB/PB 15 Series Dynamometers are fitted with a mechanical stator assembly locking device
protecting the load cell during transport. After installing the dynamometer on the test bench, proceed
as follows and refer to figure 2–5 to unlock the system:
1,
Screw the nuts  on each side of the dynamometer with three turns.
2, Unscrew the nuts
 on each side of the dynamometer until they touch the nuts . A
minimum clearance of 0.4 mm between the nuts  and the dynamometer locking device is
requested.
Note: The WB/PB 15 Series Dynamometers are not fitted with overload
protection systems. The load cell  is strong enough to cope with
any overload occurring during normal dynamometer use.
