For  motors  of  lower  amper-
age, set jumper J2 to the cor-
responding  position  for  the
motor  being  used.    See
Figure  13  on  page  9  and
Table 5.

Note:

For low (L) motor cur-

rent  settings  (0.8A,  0.5A,
0.4A,  0.3A,  and  0.2A),  it  is
necessary  to    remove  resis-
tor R35 by cutting it out of the
circuit.    Cut  the  leads  at  the
locations shown in Figure 14.

WARNING!  Disconnect AC line before cutting out resistor R35.  Use an insu-
lated cutter and wear safety glasses.

C. Timed  and  Non-Timed  Current  Limit

Selection (J3) –

Jumper J3 is factory set

to “TCL” position for timed current limiting
operation.  See Figure 15.  For non-timed
current limiting operation, set jumper J3 to
“NTCL” position.

TCL (Timed  Current  Limit)  –

When

jumper J3 is set to “TCL” position, the con-
trol  will  go  into  “STOP”  after  it  is  in  over-
load  for  a  predetermined  amount  of  time
(set by the TCL trimpot).

Resetting  the  Control  After  TCL –

To  reset  the  control  after  it  has  gone  into  TCL,

momentarily  set  the  Start/Stop  switch  to  “START”  position  or  disconnect  and  reconnect
the AC line.  If an On/Off AC Line Switch is installed, set it to “OFF” position and then back
to “ON” position.  If the Start switch is jumpered (START and COM terminals connected),
the control must be restarted by disconnecting and reconnecting the AC line.
