Installation & Start Up

Dyn-Loc IV and Customer-Supplied Control Start-Up

When the PAU is powered up in the Automatic Reset Mode the dynamometer

could power up in the same state it was in when power was turned off.

1. Validate that the conguration listed on the cover of the manual, exterior of the unit, and

the sub-panel are identical and appropriate for your application. If these values do not

match or are not appropriate for your application, please contact Dyne Systems.

2. Verify the integrity of power wiring (i.e. no shorts to ground, verify coil resistance, etc).

3. Power up the Dyn-Loc IV (or customer controls).

4. Apply power to the PAU. When power is applied a reset is not required. The following

faults are self-restoring:

• SCR OverTemp • Current OverCmd

• Coolant OverTemp • Spare Safeties

• Coolant P/F

The following faults require the power to be turned off and the fault corrected before

reapplying power:

• I Current Err

• Current Reversed

• No Field Current

5. The following will appear on the display for ~3 seconds:

Eddy-Current PAU

XX.X A max VX.X

XX.XA - The maximum current of the PAU (15, 30, 50, 100)

VX.X - The version of rmware

6. The following will then appear on the display:

PAU:Ok Off

0% 0.0A

PAU:Ok - Signies everything is okay, or else the word Fault is displayed (refer to

Wall Mount Troubleshooting Guide on page 26).

Off - PAU is not enabled

% - Percentage of command signal 0-10VDC or 0-20mA

A - Amount of current being applied to coil

If Fault is displayed, power down the Dyn-Loc IV (or customer controls) and PAU, correct

the fault and go back to Step 3.

7. Perform the Max Current adjustment if this is the rst time use. (See Appendix A, p.32

for setting Max Current.)

8. Your DS820F PAU is ready for use.
