© SP Scientific 2012 

External Connections 

 

CAUTION: REMOTE CONNECTIONS SHOULD NOT BE RUN NEAR OR PARALLEL TO AC 
POWER LINES OR IN THE VICINITY OF EQUIPMENT THAT GENERATES LARGE ELECTRICAL 
FIELDS. 

 

RS-232 Remote:  

To comply with Semi-S2 requirements, the RS-232 cable should be shielded with 
ferrites. 
 

37-pin Remote I/O 

To comply with Semi-S2 requirements, the 37-pin cable must be shielded. 
 

Remote Temperature Sensor 

An external 100-ohm RTD sensor is provided for remote control and temperature 
display. 
 

Remote EMO Override 

Ensure the assembled Remote EMO override CPC connector, labeled RC-1462-A-1, 
is inserted into the “Remote EMO” receptacle on the rear of the machine.  If you do 
not have the EMO Override CPC connector installed your machine WILL NOT
