 2  QUICK-START INSTRUCTIONS 

Important:

 You must read these simplified instructions before proceeding.  These instructions 

are to be used as a reference only and are not intended to replace the details provided herein. 
You must read the Safety Notice on, page 11, before proceeding. 

    2.1   Connections 

(See Figure 3, on page 14).

2.1.1

AC Line.

Connect AC line voltage to terminals L1 and L2. Be sure jumpers J2A and J2B are both 
set to the correct input line voltage 115 or 230 VAC. Connect ground wire (earth) to 
green ground screw on case. 

2.1.2 Motor. 

 A.

   Permanent Magnet (PM) Type. Connect motor armature leads to A1 (+) and A2 (–). 

         Be sure jumper J3 is set to the proper position “90V" for 90 volt DC motors and 
         “180V" for 180 volt DC motors.  
 

Note: 180 volt DC motors must be used with 230 VAC line, 90 volt motors can  be  used 
             with a 230 VAC or 115 VAC line. See Section 6.3, on page 26. 

 B.

    Shunt Wound Motors. Connect motor armature as above. Connect full voltage 

                  shunt field wires (90 volt motors with 100 volt fields and 180 volt motors with 200 
                  volt fields) to F1 and F2. Connect half voltage field wires (90 volt motors with 50 
                  volt fields and 180 volt motors with 100 volt fields) to F1 and L1. See Section 4, 

          on page 16. 

  2.2   Speed or Torque Mode – 

Jumper J1 is factory set for speed control operation ("SPD").   For 

torque control, set J1 to "TRQ" position. See Section 6.1, on page 23. 

 2.3   Armature Current - 

Jumper J4 is factory set for 10 amp motors (10A). For lower amperage   

        motors, place J4 in the proper position. See section 6.4, on page 27 for details. 

  Note: The factory setting  for Current Limit is 150% of the nominal current setting, e.g., if J4 is 

             selected  for 10 amps, the actual CL setting will be 15 amps. 

2.4   Trimpot Settings – 

All trimpots have been factory set in accordance with Figure 3, on page 

14. See  Table 3, page 6, for descriptions. 

2.5   Diagnostic LEDs – 

After power is turned on, observe LED’s to verify proper control  function. 

See Section 9, on page 34. 

 2.6   Armature Fuse - 

The correct size armature fuse 

must be installed

, depending on the rating  

              of the motor. Control will not operate if fuse is not installed. See Section 4.1.2, page 16 and    
       Table 7, on page 17.

 2.7   START/STOP Switch -

 The BC154 / BCWD140 contains a built-in manual start/stop                 

       switch. This switch must be used  to start the control each time AC power is lost. To                    
       override this function, see  Section 4.7.3, on page  20.
