Return for Pin 7, 8, 9, 10, 11, 12. 
Short to Pin 14 to permit operation.  Internally 
tied to 5V through a 2.49k resistor. 
Return for Pin 13 (ESTOP). 
Return for Pin 30 (USER_PWR). 
Return  for  Pin  1  (ON/OFF_HV)  and  Pin31 
(ON/OFF_ISO). 
Return for Pin 3, 4, 5, 19,  20, 33, 34.  This 
control  return  is  optically  isolated  from  the 
output power negative terminal of the power 
supply (up to 500 VDC).

Remote control input for current programming 
using a voltage source: 0-5 VDC or 0-10 VDC 
= 0-100% of full-scale output current. Do not 
exceed an input of 12 VDC. Signal return is Pin 
18. 
Current  source  of  1  mA  for  remote  current 
programming using a resistance connected to 
signal return Pin  18: 0-5  kΩ  or  0-10kΩ  =  0-
100% of full-scale output current. 
Monitor signal for output current: 0-10 VDC = 
0-100% of full-scale output current. Minimum 
recommended load resistance is 100 KΩ and 
maximum load is 20kΩ. Circuit return is pin 22. 
Return for Pin 6, 21, 35. 
User digital output, cause to be assigned by 
user.    Output  high  state  either  min  4.5V  or 
voltage  on  Pin  30  (USER_PWR)  minus  1V, 
whichever is higher. Maximum current of 0.5A. 
Output low for CV and high for CC. Output high 
state  either  min  4.5V  or  voltage  on  Pin  30 
(USER_PWR) minus 1V, whichever is higher.  
Maximum current of 0.5A.
