Troubleshooting A Test - York HFG02 Operation Manual

HFG02 Operation Manual
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 HFG02 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 HFG02 turned on but with no
running test for approximately 10 to 15 minutes before fully powering down.

5.7 Troubleshooting a test

The HFG02 monitors the Test Supply input from the Harmonics and Flicker Test
System and reports the measured voltage and frequency on the front panel display
(see Table 2). If an invalid voltage or frequency is detected, the test load operation
will be disabled (Test Enable display will be OFF).
The test load operation will also be disabled if the HFG02 detects too many
dropped voltage cycles or interruptions from the Test Supply.
If the HFG02 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 HFG02 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
HFG02 before fully restarting. If fully restarting the device fails to clear the error,
the HFG02 may require servicing.
The Alarm indicator will also fully turn on if a serious error has been detected with
the Test Supply voltage e.g. surge or transient overvoltages sufficient to cause
damage to the HFG02 itself. This error can be cleared by disconnecting the Test
Supply and restarting the HFG02.
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.
