Installation
Power-Up Procedure
4. When prompted by the Model 430 Programmer, energize the power
supply and press ENTER on the Model 430 Programmer.
Warning
All power supply parameters, both hardware and software, have
been set at the AMI factory. Power supply control, with the exception
of powering ON and OFF , is done by way of the AMI Model 430
Power Supply Programmer. No field adjustments or reconfiguration
of the power supply should be attempted in the field unless
specifically described in this document or recommended in writing
by an AMI Technical Support Representative.
5. Enter a stability setting of 100%. Refer to sections 3.3 on page 25
and 3.7.9 on page 39.
6. Verify the various setup menu values for the system (with the
exception of the stability setting, which is to be temporarily left at
100%). If the power supply system was purchased with an AMI
magnet, AMI has preset the setup menu values for proper
operation. See sections 3.3, 3.5, 3.9 and 3.10 for more discussion of
the setup menu values and their entry into the Model 430
Programmer.
7. Set the Model 430 Programmer to display current (rather than
field). Refer to sections 3.2.1 and 3.7.5.
8. Set the ramp rate to 1 A/sec. Refer to sections 3.3 on page 25 and
3.7.1 on page 33.
9. Set the target current to 10 A. Refer to sections 3.3 on page 25 and
3.6.2 on page 31.
10. If a Persistent Switch is installed, set the PSw P/S Ramp Rate to 10
A/sec. Refer to paragraph 3.10.2.11 on page 56
11. Initiate ramping to the target current by pressing the RAMP /
PAUSE key (status indicator changes from P to ).
12. The system should ramp to 10 A in approximately 10 seconds.
Verify this is the case (if a PSwitch is installed and in the cooled
state, ramp time to 10 A should be slightly less than 2 seconds).
13. When the target current is achieved, the FIELD AT TARGET LED
will be illuminated. The display should show “
+10.00 A -
”
indicating that the Model 430 Programmer is in the holding mode
at the target current value (+10.00 A).
