Power-On Self tests:
When the tester is powered on, a number of messages can possibly
appear as the Tester performs safety tests on itself and the mains
power supply.
If a voltage greater than 30V is detected on the neutral input line or
the Earth is missing then the following message will be displayed.
Check for incorrect wiring on supply.
The next test will check for a Earth connection. If there is no Earth
connection, the following message will appear.
Check for incorrect wiring on supply.
The Tester will fail the Earth check if it is being supplied with a
balanced supply (e.g. isolating transformer) since it will detect phase
voltage on both L and N supply connections. Only continue if
certain that the supply is balanced and the Earth on the Tester
connection is secure.
If all the above is checked OK, then the Safe Check 8 may be faulty.
Contact your Seaward Agent for repair.
The unit then completes an internal check. If any faults are found
then the following message will be displayed: -
