Resistance Programming of OVP 

 
Setting up for resistance programming OVP is as follows: 
 
1. 

Set Position-3, OVP, of the INTFC SETUP switch to OFF (down) for 0-5VDC 
programming range. 

 
2. 

Connect the external programming resistance, 0-5kΩ,  to the ISOLATED ANALOG 
INTERFACE connector, from Pin-16 to Pin-12. 

 
3. 

Connect a jumper from Pin-16 to Pin-3. 

 
4. 

Program the other parameters to the desired limit values: VOLTAGE PROGRAMMING 
INPUT, Pin-9, and the CURRENT PROGRAMMING INPUT, Pin-10, with respect to pin-
12. 

 
5. 

Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG INTERFACE 
connector to Pin-15. 

 

4-20mA Current Source Programming of Output Voltage 

 
Setting up for 4-20mA programming of the output voltage is as follows: 
 
1. 

Set Position-1, V, of the INTFC SETUP switch to OFF (down) for 0-5VDC programming 
range. 

 
2. 

Connect the external 4-20mA programming current source to the ISOLATED ANALOG 
INTERFACE connector, with source at Pin-9 and return at Pin-25. 

 
3. 

Connect a jumper from Pin-25 to Pin-12. 

 
4. 

Connect a jumper from Pin-8 to Pin-20. 

 
5. 

Program the other parameters to the desired limit values: CURRENT PROGRAMMING 
INPUT, Pin-10, and the OVP PROGRAMMING INPUT, Pin-3, with respect to pin-12. 

 
6. 

Connect Pin-1, ANALOG-CONTROL, of the ISOLATED ANALOG INTERFACE 
connector to Pin-15. 

 
 

4-20mA Current Source Programming of Output Current 

 
Setting up for 4-20mA programming of the output current is as follows: 
 
1. 

Set Position-2, I, of the INTFC SETUP switch to OFF (down) for 0-5VDC programming 
range. 

 
2. 

Connect the external 4-20mA programming current source to the ISOLATED ANALOG 
INTERFACE connector, with source at Pin-10 and return at Pin-13.
