Allow the controller to count up to its top limit.
4.2.2.10
Check that all of the output relays are now switched on.

Reduce the current to zero:
both the IND LED and the CAP LED should now be extinguished.
4.2.2.12
Reverse the input current connections, (see WARNING note above)
Increase the current from zero slowly. The CAP LED should flash when the 10%
input level is exceeded. The controller should now start to count down.
4.2.2.13
The setting of the c/k potentiometer should be checked at several different levels
by noting the inputs required to exceed the CAP and IND trip levels.
4.2.2.14
If it is required to check operation of the Target Cos Phi potentiometer as well as
the c/k potentiometer, it will be necessary to use a test system with phase angle
adjustment. The centre point of the IND and CAP deadband should be seen to
move by the angle represented by the target cos phi selected.
