Wavecom Instruments Fully Integrated Test N Print Unit - User Manual
22
Procedure:
1. Complete a Visual Inspection. For details refer to the First Test section. If the device passed the Visual Inspection,
continue with the following instructions, if not, refer to the First Test section.
2. Press the return key to view Main menu B.
3. Press a function key (as follows) to start the test/s. Press F1, F2 or F3 depending on the type of device you are
testing). F1 = Earth Leakage, limit set to MAX then 5mA fail. F2 = D/insulated leakage and ext. leads, limit set to MAX
then 5mA fail. F3 = RCD leakage.
CONFIRM IF SAFE TO CONTINUE? OK/QUIT. IF OK, DEVICE WILL POWER SWITCH ON. ENSURE ITEM AND
ENVIRONMENT FOR SAFE OPERATION!
4. Results are displayed, read and record appropriately.
5. Unplug DUT.
6. Press Enter until you return to the main menu.
If the result was a pass - Tag with the appropriate tag including "next test due" date and "return to service".
If the result was a fail - Tag with a DANGER TAG and remove from service.
The Leakage Test allows the user to operate the appliance in normal operation conditions and measure its Operating Leakage
current. The displayed parameter is mA. The mA Display Range 0.0 to 22.0 mA.
A predefined value for individual class types is programmed into your TNP - Series appliance testers. These limits are set
according to the AS/NZ3760. Should these values change in future it can be simply altered in firmware. A Pass / Fail will also
be displayed at the end of the test.
The run time period can be adjusted (by 5sec increments). The value can be changed by selecting the leakage test time in the
options menu. See the special functions section of the manual for more details. The factory default setting is 20sec. The value
for the leakage runtime is also used for the power test (plus models only).
Caution: Before operating ensure the equipment is firmly secured to eliminate the possibility of causing injury or damage. This
function will power the Unit on, please make sure the drills or any blades of any rotating devices have been
removed prior to any testing and have clearance from body or object. Appliances may jump off benches and may
need to be secured by clamping them, or they may cause serious damage if not secured properly.
The leakage test time is adjustable. These can be done by turning on the TnP in settings mode / Tester mode. Turn the unit
on while pressing F3. This is explained in later section.
RCD Test – Time Test / Ramp Test– Menu B – F3
Please Note: when any RCD testing is to be carried out on any circuit that is protected by an RCD in the main switchboard
(upstream), it’s most likely to trip this upstream RCD. When performing RCD trip time or Ramp current tests on any (portable)
RCD devices, the RCD in the switchboard may trip faster. This is due to increased upstream levels of leakage current from
the additional circuits and devices connected to it. The fixed RCD’s can also have better connectivity, sensitivity and
mechanical mechanisms.
To avoid tripping large areas in the work place monitored by the switchboard RCD it is suggested that an RCD (Isolation
Transformer) be used. These are designed specifically for the purposes of field RCD tripping.
DO NOT use these Transformers for any other purpose. Ratings 240VAC in 240VAC Out @ 30VA Fuse protected Primary
winding 500mA
To perform RCD tests the TnP supply lead needs to be plugged in to the RCD device to be trip tested. For tripping switchboard
mounted (Fixed) RCDs Plug TnP into GPO marked RCD protected or if known to be protected circuit. (Diagram 2)
(Isolation Transformer Required) If testing portable RCD devices on power boards or extension leads plug TnP into power
board or lead (Isolation Transformer Required) [Not required if using TnP Battery series with 4.3 advanced motherboards]
