Seaward PAC3760 - Manual (Page 2)

APPLIANCE TESTS
Preparing an appliance for test
• Plug in the PAC3760 to a suitable mains supply
• Conduct a visual inspection of the appliance
• Determine the Class of the appliance to be tested
• Plug the appliance into the PAC3760 front panel mains
socket and connect the test probe to a touchable metal
part on the appliance
• Choose ➀ ➁ for an insulation test or ➂ ➃ for a
‘power on’ leakage test
➀ Class I test with insulation test
• Press the CL I button once
• A pass is indicated by two ticks and “PASS”
• A fail is indicated by any cross: and “FAIL”
➁ Class II test with insulation test
• Press the CL II button once.
• A pass is indicated by one tick and “PASS”
• A fail is indicated by a cross: and “FAIL”
➂ Class I test with ‘power-on’ leakage test
• Press the CL I and ‘LKGE’ button together once
• Wait for a and . This indicates that power can
now be applied using the ‘LKGE’ button
• Pressing the ‘LKGE’ button causes and to appear
indicating that the front panel mains socket is now live.
Ensure that the appliance is powered
Beware of moving or hot parts on the appliance
• Power is applied for 30s unless the user presses the
‘LKGE’ button and power is terminated
• Power off is indicated by only (no )
• A pass is indicated by two ticks and “PASS”
• A fail is indicated by any cross: and “FAIL”
➃ Class II test using ‘power-on’ leakage test
• Press the CL II and ‘LKGE’ button together once
• Wait for the . This indicates that power can now be
applied using the ‘LKGE’ button
• Pressing the ‘LKGE’ button causes and to appear
indicating that the front panel socket is now live.
Ensure that the appliance is powered
Beware of moving or hot parts on the appliance
• Power is applied for 30s unless the user presses the
‘LKGE’ button and power is terminated
• Power off is indicated by only (no )
• A pass is indicated by a tick and “PASS”
• A fail is indicated by a cross: and “FAIL”
READ INSTRUCTIONS FOR USE
Due to the potential hazards associated with any electrical
circuit it is important that a user is fully familiar with
instructions covering the capabilities, applications and
operations of the instrument.
The user should ensure that all reasonable safety
procedures are followed and if any doubt exists should
seek advice before proceeding.
Front panel graphics are provided to remind the user of
the six test arrangements.

LEAD TESTS
Preparing a lead for test
• Plug in the PAC3760 to a suitable mains supply
• Conduct a visual inspection of the lead
• Connecting IEC Leads: plug into the front panel mains
socket and connect the IEC connector to the IEC inlet
receptacle on top panel
Caution, do not connect the IEC inlet receptacle
directly to mains power
• Connecting extension leads: plug into the front panel
mains socket and connect the IEC connector to the
IEC inlet receptacle on top panel using the extension
lead adapter accessory
• Choose
➄ earth continuity, insulation and polarity test or
➅ earth continuity and ‘power-on’ leakage test
• NB. The PAC3760 automatically detects a “lead”
indicates a lead and includes polarity testing in
the sequence
➄ Class I lead test with insulation and polarity test
• Press the CL I button once
• A pass is indicated by two ticks and “PASS”
• A fail is indicated by any cross: and “FAIL”
➅ Class I test with ‘power-on’ leakage test
• Press the CL I and ‘LKGE’ button together once
• Wait for a and . This indicates that power can
now be applied using the ‘LKGE’ button
• Pressing the ‘LKGE’ button causes and to appear
indicating that the front panel socket is now live
• Power is applied for 30s unless the user presses the
‘LKGE’ button and power is terminated
• Power off is indicated by only (no )
• A pass is indicated by two ticks and “PASS”
• A fail is indicated by any cross: and “FAIL”
ADVANCED DIAGNOSIS OF A TEST FAIL
PAC3760 indicates the type of failure when an
appliance or lead fails a test sequence.
• If an earth continuity test fails, there is a single left
hand cross and all other tests are prohibited
• If an insulation test fails there is a right hand cross
with RINS underneath
• If a power-on leakage test fails there is a right hand
cross with (no ‘RINS’ underneath)
• If a lead polarity test fails there is a right hand cross
and a further small icon at the bottom indicating
open circuit Live/Neutral, short circuit Live/Neutral, or
crossed Live/Neutral
• PN and NE indicates Live/Neutral reversed
• PE, PN and NE indicates a PE fault
