i. SIMPLIFIED OPERATING INSTRUCTIONS
A. Power Connection – Connect the AC line to L1 and L2 terminals of Terminal Block
TB1 and the ground wire (earth) to the green ground screw, as shown in Figure 4, on
page 10 and as described in Section IIA, on page 10 and Section IIB on page 10.
Be sure Jumpers J1 and J2 are both set to the corresponding AC line input voltage
position, as described in Section IIIA, on page 14.
B. Permanent Magnet (PM) Motor Connection (Two Wire Type) – Connect the motor
armature to M1 (+) and M2 (-) terminals of Terminal Block TB1, as shown in Figure
4, on page 10 and as described in Section IIC, on page 10. Be sure that Jumper J3
is set to the corresponding motor voltage position, as described in Section IIIB, on
page 14 and Jumper J4 is set to the corresponding motor current, as described in
Section IIID, on page 15.
Note: Do not use F+ and F- terminals of Terminal Block TB2 for any purpose other
than to power the field of a shunt wound motor. Do not use F+ and F- terminals of
Terminal Block TB2 for PM motors. Do not use F1 and F2 quick-connect terminals
for any purpose other than to power the optional Signal Isolator SIRC (P/N 8842).
Note: Motor performance and efficiency, including brush life, may be adversely
affected when operating the control in stepdown mode (208/230 Volt AC line with 90
Volt DC motors).
C. Shunt Wound Motors (Four Wire Type) – Connect the motor armature as described
in Section IIC, on page 10.
Connect full voltage field wires (90 Volt DC motors with 100 Volt DC field and 180 Volt
DC motors with 200 Volt DC field) to F+ and F- terminals of Terminal Block TB2, as
described in Section IID, on page 10.
Connect half voltage field wires (90 Volt DC motors with 50 Volt DC field and 180 Volt
DC motors with 100 Volt DC field) to F+ terminal of Terminal Block TB2 and L1 ter-
minal of Terminal Block TB1, as described in Section IIE, on page 11.
Note: Do not connect motor armature leads to F+ and F- terminals of Terminal Block
TB2 or to F1 and F2 quick-connect terminals. Do not use F1 and F2 quick-connect
terminals for any purpose other than to power the optional Signal Isolator SIRC (P/N
8842).
D. Start/Stop Switch – The control is supplied with a prewired Start/Stop Switch, as
described in Section IIG, on page 12. This switch must be used to start the control
each time the AC power is lost or the control shuts down in TCL. To eliminate this
function, see Section IIG, on page 12.
E. Motor Current – Jumper J4 is factory set for 10 Amp motors. For a lower current
motor, set Jumper J4 to the corresponding motor current, as described in Section
IIID, on page 15.
Note: The factory setting for Current Limit is 150% of the nominal current setting
(example: if Jumper J4 is set to the “10A” position, the CL trimpot is calibrated for 15
Amps).
F. Trimpot Settings – All trimpots have been factory set, as shown in Figure 2, on page
7. Trimpots may be readjusted, as described in Section VIII, on page 19.
G. Diagnostic LEDs – After power has been applied, observe the LEDs to verify prop-
er control function, as described in Section IX, on page 22.
IMPORTANT – You must read these simplified operating instructions before pro-
ceeding. These instructions are to be used as a reference only and are not intended
to replace the detailed instructions provided herein. You must read the Safety
Warning, on page 5, before proceeding.
