5.5.2 LINK SELECTION
LINK NAME DESCRIPTION
JP1
AUX Reference from auxiliary input
INT Internal reference from ramp generator
JP2
PULSE Feedback from magnetic pick-up input on J1
TACH Feedback from tachometer input on J2
5.5.3 TERMINALS
TERMINAL NO. NAME DESCRIPTION
J1
1
PULSE
FEEDBACK
Connection point for pulse pick up feedback
2 COMMON
Common point for pulse pick up feedback
and auxiliary reference
3 AUX REF
Input for auxiliary reference when JP1 is at AUX
Range is 0 - 15V maximum
4 NO Normally open starter status contact
5 NC Normally closed starter status contact
6 COM
Common of ramp status form C contacts
Energized when unit started and de-energized when
ramp reference or auxiliary input reaches 0V
J2
TACH
FEEDBACK
Input for tachometer feedback
Scaled by resistor at J3
J3 CAL R
Scaling resistor for tach feedback
Resistor should be 1 Watt or greater
CAL R = (max. tach volts -13.4) ÷ 12 in kilo-ohms
5.5.4 START-UP
5.5.4.1 STEP (RV2) should be set at 0 and the RATE jumper (JP3) must be OFF or
removed on the CA392 control card. Ensure SW2 is in correct position.
5.5.4.2 Set JP1 and JP2 on CA385 at settings for your application. If tach feedback is being
used, install resistor as per above procedure in TERMINALS.
5.5.4.3 Set all pots to 50%.
5.5.4.4 Start unit and adjust speed feedback according to the procedure in the table
POTENTIOMETERS, RV2 description when at full speed. If accel or decel is too
slow adjust appropriate pot. If motor does not seem to get up to full speed, reduce
the level at TP1 by turning RV2 clock-wise.
