2.7 DS9000 PRELIMINARY SET-UP
2.7.1

INITIAL SETTINGS FOR SWITCHES

The following procedure should be followed to ensure all connections have been made correctly and
that setup switches are in the correct position.
2.7.1.1

SET-POINT CONTROLLER OR FOLLOWER MODE

DS9000 units are suitable for operation as either a Set-Point Speed Controller or as a Follower. Move
Dip Switch 1 to the correct position for this installation.
DipSW1 OFF – Set-Point Controller
ON - Follower Mode
For initial sset-up select Set-Point Controller even if unit will be used as a Follower in
final installation.
2.7.1.2 CLOSED LOOP / OPEN LOOP SELECT
DipSW2 OFF – Enable PI and Position Control
(Closed Loop Control)
ON - Disable PI Controller in Set Point Control Mode
(Scaled 0-10V to 0-1800 RPM)
- Disable "Position Lock" in Follower Mode (Speed Controller Only)
- When ON the display will show "OPLP" indicating Open Loop Operation.
2.7.1.3

CONTROLLED MOTOR FEEDBACK SIGNAL

DS9000 units will work with several types of Feedback signals from a pulse tach generator or encoder
mounted on the motor being controlled. Move Dip Switch 3 to the correct position for the feedback
device in this installation.
DipSW3 OFF – Magnetic pick-up (Seco MTK type or equivalent) or Zero Cross Over Sensor
ON - Encoder or Open Collector type (Input impedance 3.3K)
2.7.1.4 REFERENCE MOTOR FEEDBACK SIGNAL (Follower Mode Only)
DS9000 units will follow a signal from several types of pulse tach-generators or encoders mounted on
a motor or shaft. It can also follow a variable frequency signal operated electronically. Move Dip
Switch 4 to the correct position for the Reference signal in this particular installation.
DipSW4 OFF – Magnetic pick-up (Seco MTK type or equivalent or Zero Cross Over Detector
or electronic signal)
ON - Encoder or Open Collector type (Input impedance 3.3K)
2.7.1.5

TACH DISPLAY VALUE

The digital display in the Follower mode can show either the Reference signal or the speed of the
controlled motor. Move Dip Switch 5 into the required position. This switch has no effect when used
as a master or set point controller.
DipSW5 OFF – Tach display shows Reference RPM or Engineering Units
ON – Tack display shows RPM or Engineering Units of Controlled motor.
