COIL OUTPUT (dc) INPUT

INITIAL SET UP - When Using Manual (Potentiometer) Control:
1) Determine the 100% rated current of the brake (or clutch) from the data sheet, or estimate it from the formula:
100% rated current = (rated voltage) / (coil resistance, ohms)
The rated voltage is listed on the label of the brake or clutch.
2) For safety, disconnect the A.C. power.
3) Set 'SWITCH' (on underside of case) to position 2, 'FRONT PANEL POTENTIOMETER' position, so the output
current is controlled by the % Rated Current Potentiometer.
4) Set the SPAN MAX. potentiometer fully counter-clockwise (for minimum output current).
5) Connect A.C. power.
6) Set the % RATED CURRENT potentiometer to 100% (for maximum output current).
7) SPAN MAX. - Turn the SPAN MAX. potentiometer clockwise until output current equals the 100% rated current of
the brake (or clutch).
8) SPAN MIN. - Set the % RATED CURRENT potentiometer to 10%. Adjust the SPAN MIN. potentiometer until the
output current is 10% of rated current.
9) Recheck Steps 6 - 8.
ADJUSTMENTS - When Using Manual (Potentiometer)
Control:
% RATED CURRENT POTENTIOMETER - To control
output current, from 0% to 100%.
SPAN MAX. - Sets the maximum output current. Is a
15 turn potentiometer. Use the miniature plastic
screwdriver provided to make adjustments.
SPAN MIN. - Sets the output current to zero when the
% RATED CURRENT potentiometer is set to zero. Is a
15 turn potentiometer. Use the miniature plastic
screwdriver provided to make adjustments.
