2.4 External Control 0-5 VDC - Voltage Following Input Mode
In order for the stepper controller board to recognize and accept a 0-5 VDC control input, all speed
switches 1-7 (Switchboard #200293, Figure 2,) must be turned off. The board will not respond to a
voltage input unless all speed switches are off. Once off, a DC voltage (5.0 volts max.) signal may be ap-
plied via the input cable (P1) Pin 8 (RED) (+ voltage) and Pin 7 common returns. A variation of that volt-
age will linearly vary the motor speed. Maximum speed using a 0-5 volt DC input signal is limited to
approximately 2000 rpm. (The smallest increment is about 6 rpm.)
2.5 Continuous (Constant Run) Mode
By turning off the Dispense switches 9, 10, 11 on the Switchboard, and having a current signal at P1 Pin
9 (VIOLET), the motor will run at a continuous pre- set speed. This condition is useful for priming the
system.
Speed (factory set at 320rpm) may be changed according to section 5.0
3.0 Motor Direction
Factory preset to CLOCKWISE looking into the pump head. Suction is on the RIGHT, discharge on the
LEFT, when the pump head is facing you. Counter Clockwise rotation is settable by closing SW12 on
Switchboard # 200293 inside of the box. See section 5.0 * This Function is not Accessible on Connector
P1.
4.0 Power Supply requirements
A single 24 VDC power supply delivering 2.0 amps (minimum) of current is required for driving the
IDS 2000A. Connect positive (+) to P1 Pin 1 (RED) and negative (-) to P1 Pin 2 (BLACK). An addi-
tional power supply may be needed to provide input currents to the control inputs, if they are not internally
sourced from your controller.
