If your OC950 is not already installed in your SC900, then use
the following instructions to install it.
CAUTION
NEVER insert or remove an Option Card with the Control
AC Power (J1-5,6) active. Damage to the base SC900 or the
Option Card could occur.
Procedure
1. Remove Control AC Power from the SC900. The system
status LED should be blank.
2. Loosen the two locking screws counterclockwise on the
existing face plate or existing Option Card and remove.
3. Position the new Option Card so that the silk screen reads the
same as the base SC900.
4. Insert the Option Card by sliding it in all the way until it is
flush with the base SC900.
5. Tighten the two locking screws by turning clockwise.
Wiring
connections
Connect the motor, feedback, and AC Power cables as shown in
the following Connection Diagram but do not apply the AC
Power at this time. It is recommended that Pacific Scientific
motor and feedback cables be used during setup since improper
cabling is the number one cause of start up problems.
The RS-232 cable made by Pacific Scientific (order number
CS-232-750) can be used to connect the 9 pin serial port socket
on the OC950 to the PC. If this cable is unavailable, a simple 3
wire cable can be made using the wiring diagram shown on page
3-11.
The last connection needed is to provide the hardware enable to
the SC900 via J4-6 and I/O RTN on J4-5. Preferably connect a
toggle switch between J4-6 and J4-5. If a toggle switch is not
available a clip lead that can connect or not connect J4-6 to J4-5
will do.
