Troubleshooting A Test - EMS HFG01 Operation Manual

HFG01 Operation Manual
Configure the Harmonics and Flicker Test System to measure harmonic or flicker
disturbance as per the system instructions, with the Test Supply configured to
provide the required voltage and frequency.
Once the Test Supply has been safely connected, the Harmonics and Flicker Test
Supply can be enabled.
Select the required test load operation using the Test Mode switch .
The chosen test load operation can be enabled before or after the Harmonics and
Flicker Test System has started the test routine. When ready to enable the load
operation, press the Start Test switch . The Test Enable display should
indicate that the test is running.
Pressing the Start Test switch again will disable the running test. Changing the
Test Mode selection switch will also disable the running test. The new selected
test will need to be started by pressing the Start Test switch again.
Note:
If the HFG01 test has been running for more than 2 hours continuously it is
recommended that it is allowed to cool down before power is finally removed, to
reduce any latent heat build-up. To do this, leave the HFG01 turned on but with no
running test for approximately 10 to 15 minutes before fully powering down.

5.6 Troubleshooting a test

The test load operation will be disabled if the HFG01 detects too many dropped
voltage cycles or interruptions from the Test Supply.
If the HFG01 load exceeds its recommended operating temperature, the test load
operation will be disabled (Test Enable display will be OFF) and the Alarm
indicator will flash at a steady rate. Once the temperature has returned to
normal the Alarm indicator will turn off and the test can be resumed.
If the HFG01 detects a system error, the Alarm indicator will fully turn on without
flashing. The system error will need to be cleared by removing all power from the
HFG01 before fully restarting. If fully restarting the device fails to clear the error,
the HFG01 may require servicing.
A flowchart for troubleshooting if the test cannot be enabled is shown in Figure 6.
In the case of other problems, please contact your supplier for advice.
