Powered Tests
Warning
Mains voltage applied to appliance
The following powered tests differ from the previous tests in that they apply mains supply voltage to the
appliance to perform their functions:-
•
Load (Operation) Test
•
Earth Leakage Test
•
Enclosure Leakage Test
•
Patient Leakage Test (AC & DC)
•
Patient Auxiliary Test (AC & DC)
•
F-Type – Mains on Applied Parts Tests
•
SIP / SOP – Mains on Signal Input / Signal Output Test
The Analyser performs an initial low voltage test to establish that the appliance can be safely powered.
Warning
It is important that the user verifies that an appliance with moving parts is safely mounted to
allow movement without causing damage to equipment or personnel.
If the potential load current is too high, a warning message appears, allowing the user to continue. This
message will be displayed if a Live to Neutral short exists or the EUT mains current consumption is too high,
and if tests are continued the Analyser’s fuses will blow.
If the potential load current is low, a warning message appears to allow the user to check that the appliance is
switched on, and all fuses are intact.
NOTE: If the measured value exceeds the values specified in BS EN 60601 the analyser will halt the
automatic sequence. The user now has the option of proceeding with the remaining tests or aborting
the sequence. To proceed with the remaining tests, press the START key, to abort press either the UP
ARROW, DOWN ARROW or SELECT key.
The Analyser also performs an internal safety test to verify that internal relays are properly set before applying
full mains supply to the appliance.
