Insulation Resistance Test - Arjohuntleigh FLOWTRON UNIVERSAL Service Manual

Flowtron Universal Service Manual
10.4 Connect the other end of the test equipment to the earth/ground pin on the pump's mains/power
cordset.
10.5 A 25A (nominal) current is passed for 10 seconds between the earth/ground test pad on the
control PCB assembly and the earth/ground pin of the mains/power cordset. The resistance
should NOT exceed 0.2Ω.
Note: If the test equipment shows a very high resistance value, it is probably due to the test
probe not touching the earth/ground test pad. Remove and re-insert the test probe or a
broken earth/ground wire.
Note: This test can be conducted with a Portable Appliance Tester. Alternatively, a Multimeter/
Continuity Tester can be utilised, but the resistance is tested using a much lower current.
10.6 Remove the test probe from the earth/ground access point on the pump.
10.7 Install the case IEC cover to the rear case of the pump (Chapter 5, Page 6, Section 4).

Insulation Resistance Test

This test checks the integrity of the pump's insulation.
This test is applied between the live and neutral wires (connected together), and earth/ground.
Test Procedure
• 500 Vdc is applied to the insulation and the measured resistance must be greater than 2MΩ.
Note: This test can be conducted using a Portable Appliance Tester.
Earth/Ground Leakage Current Test (USA)
This test measures the current flowing through the earth/ground wire in accordance with the ANSI-AAMI
ESI-1993 Standard (American National Standard Safe Current Limits for Electromedical Apparatus) or
as specified in UL 60601-1).
WARNING: DANGER OF ELECTRIC SHOCK. DO NOT TOUCH ANY EXPOSED PARTS
WHILE CONDUCTING THIS TEST. DO NOT TOUCH ANY PART OF YOUR
BODY WITH THE CONTACTS OF THE PROBES.
