ADJUSTMENTS - When Using Manual
(Potentiometer) Control:
% RATED CURRENT POTENTIOMETER - The
remotely mountable potentiometer controls the
desired output current, and is adjustable from 0%
to 100%. This is used to control output torque.
SPAN MAX. - Sets the maximum output current.
The 10 turn potentiometer is mounted on the
circuit board. 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. The 10 turn potentiometer is mounted
on the circuit board. Use the miniature plastic
screwdriver provided to make adjustments.
220 Volts A.C. input
PS-12-M2 : 0-12 VDC output
PS-24-M2 : 0-24 VDC output
INITIAL SET UP - When Using Manual (Potentiometer) Control:
1) Determine the 100% rated current of the brake (or clutch) from the data sheet, or calculate 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 SW2 to position 1, so the output current is controlled by the % Rated Current Potentiometer.
Set SWITCH SW3 towards the edge of the circuit board to select the on-board Span Max. Potentiometer.
4) Set the SPAN MAX. potentiometer fully counter-clockwise (for minimum output current).
5) Connect the digital L.C.D. ammeter. (See wiring diagram on page 1.)
6) Connect the % Rated Current Potentiometer and brake (or clutch) as shown above.
7) Connect A.C. power. (See wiring diagram on page 1.)
8) Set the % RATED CURRENT potentiometer to 100% (for maximum output current).
9) SPAN MAX. - Turn the SPAN MAX. potentiometer clockwise until the ammeter displays the current level
corresponding to the 100% rated current of the brake (or clutch).
10) SPAN MIN. - Set the % RATED CURRENT potentiometer to 10%. Adjust the SPAN MIN. potentiometer until the
ammeter shows the power supply output current is at 10% of rated current.
11) Recheck Steps 9 & 10.

ADJUSTMENTS - When Using 0-10 Volt Control:
0-10 VOLT INPUT SIGNAL - Output current is
proportional to the user's 0-10 volt input signal.
At 0 volts, output current is 0. At 10 volts, output
current is maximum.
SPAN MAX. - This potentiometer sets the
maximum output current level, when the 0-10
volt signal is 10 volts.
SPAN MIN. - This potentiometer sets the output
current to zero when the 0-10 volt signal is zero
volts.
INITIAL SET UP - When Using 0-10 Volt Control:
1) Determine the 100% rated current of the brake (or clutch) from the data sheet, or calculate 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 SW2 to position 2 so the output current is controlled by the 0-10 volt D.C. input signal.
Set SWITCH SW3 towards the edge of the circuit board to select the on-board Span Max. Potentiometer.
4) Set the SPAN MAX. potentiometer fully counter-clockwise (for minimum output current).
5) Connect the digital L.C.D. ammeter. (See wiring diagram on page 1.)
6) Connect your 0-10 volt input and brake (or clutch) as shown above.
7) Connect A.C. power. (See wiring diagram on page 1.)
8) Set your 0-10 volt signal to 10 volts. (for maximum output current).
9) SPAN MAX. ADJ. - Turn the SPAN MAX. potentiometer clockwise until the output current equals the 100% rated
current of the brake (or clutch).
10) SPAN MIN. - Set your 0-10 volt signal to 1 volt. Adjust the SPAN MIN. potentiometer until your ammeter indicates
the power supply output current is 10% of rated current.
11) Recheck Steps 9 & 10.

Ammeters
Ammeters are not interchangeable between older power supplies without
first altering solder pads on ammeter. Consult factory for details.
Ammeters may only be used without alteration with power supplies of the
same series serial number . (Example: 97-16xxx, 97-15xxx, 96-14xxx are
from 3 different series--- series 1600, 1500, and 1400)
For best accuracy after replacing ammeters, adjust the potentiometer on the
rear of the ammeter so readings equal a reference ammeter.
