Symptom
Possible causes
c) Defective supply (+/- 15V) for elec-
tronic circuit.
d) Defective SCR bridge.
e) Defective tachometer or tachometer
leads.
f) Defective speed potentiometer.
a) Shorted or grounded armature or
field connections.
b) Defective motor or armature.
a) Tachometer connections intermittent,
defective tachometer, or wrong pola-
rity.
b) Defective potentiometer P4 (max.
speed).
c) Check armature connections.
a) Intermittent potentiometer P1 (Mini-
mum speed).
b) Defective speed potentiometer or
connection from terminal 26z to po-
tentiometer.
a) Defective power supply.
b) Check relays and relay connections
(drive release).
c) Defective speed potentiometer.
d) Check motor and brushes.
e) Defective fuse F1 (10A FF).
Speed varies without change of
speed potentiometer.
Main fuse blows.
Drive does not run.
Drive runs after control release at
maximum speed without keeping
reference speed.
Drive runs after control release at
maximum speed however speed
control is set for zero speed.
This concludes the preliminary preparations and adjustments of the
Thyristor Drive Control TA-05 C.
a) Grounded armature wiring
b) Defective SCR bridge.
Motor starts without drive release
when connected to line supply.
