6.7.3 Option V and T Startup
1. Before applying power, set all potentiometer adjustments as follows.
•
Voltage Adjust Pot, Fully Counter Clockwise. (4-20ma at minumum)
•
Current Adjust Pot, Fully Clockwise. (4-20ma at maximum)
•
Voltage Feedback Trim Pot P5, Fully Counter Clockwise.
•
Current Trip Pot (option T only) P6 fully Clockwise.
•
Soft Start Pot P7, mid range.
2. Apply power and adjust the Voltage control pot or 4-20ma signal to maximum.
3. Adjust the Voltage Feedbcak Pot P5 slowly clockwise until the output voltage level
reaches maximum.
4. Reduce the manual pot or automatic signal slightly and verify the units output follows.
If not, increase the signal to maximum and readjust the P5 pot.
5. If Voltage control is responding correctly, set it to maximum and slowly decrease the
Current control signal to verify the output from the system follows the control signal.
Note:
If the load is significantly smaller than the shunt value, the current control pot/signal will
appear to have no effect until the low end is reached. This is due to the very small feedback
signal from the shunt. To properly verify the current control mode, the full rated load should be
used.
6. For option T, the system must have a full load applied to correctly adjust this feature.
7. With the system under full load and at maximum output, slowly decrease the Current Trip pot P6
by turning it counter clockwise until the units output abruptly drops to zero.
8. Verify the Red Current Trip LED is on and the relay contacats at TB4 have changed state.
9. Momentarilly press the trip reset button and verify the unit comes back on and ramps up.
10. If the unit trips again as the output ramps up, increase the P6 Trip setting slightly and reset again.
11. Increasing the soft start time by adjusting P7 clockwise will also help prevent the inrush and help
prevent the unit from tripping on a reset.
Note:
If longer ramp time is desired, add capacitor at terminals E15 and E16 on V option board. Factory
installed 100 micro farads cap for 30 second ramp. E15 is positive.
