A5. Determine whether a voltage or current
signal will be inputted on each of the channels of
the AI–14B board, and set selection jumpers
accordingly (see Figure A2).

CAUTION
KEEP ANALOG SPEED REF. (I.E. CONTROL CIRCUIT) WIRING
SEPARATE FROM MAIN CIRCUIT INPUT/OUTPUT WIRING.
CAUTION
TO PREVENT ERRONEOUS OPERATION CAUSED BY NOISE
INTERFERENCE, USE SHIELDED CABLE FOR CONTROL WIRING,
AND LIMIT DISTANCE TO 10M (33 FEET) OR LESS.
CAUTION
IF ANY OF THE CONTROL SIGNAL INPUT TERMINALS (TC1 THRU
TC3) ARE NOT USED, JUMPER THEM TO 0V TERMINAL (TC4).
