9) **** RESET DRIVE *****

10) Connect a scope to measure the voltage across one of the CT burden resistors.

Remember to use an isolation plug on scopes with ground prong on power

cord. If the burden resistors are located in an inaccessible area, the scope may be

connected to the SCR Firing Adapter point to which the burden resistor/CT wiring

terminates. (See AFM's electrical drawing set for correct interconnections.) Set

the time sweep to 1ms per division, set the voltage scale to 0.5 volts per division,

and set the scope sync to the line.

11) Observe the armature firing angle A016:ARM ALPHA under OPERATE →

DRIVE ANALOG and insure that it is approximately 120 degrees. If the firing

angle is significantly smaller, check that all analog values throughout the

ARMATURE CURRENT LOOP are all zero.

12) Place a clamp-on ammeter on one of the armature leads. This meter will be used

to insure that excessive current is not applied to the motor while phasing the CT

feedback. Closely watch the ammeter current while performing the following

step. The armature current should not rise above 10% of the motor nameplate

armature current.
