Frequently Asked Questions
What is the 70-2900-0540-2?
It is the catalytic bead combustible (LEL) sensor element that AimSafety catalogues for the PM400 four-gas portable monitor, supplied under its own part number.
What is the expected sensor life?
AimSafety publishes a sensor life of greater than 2 years for this element.
Is there a published procedure for changing a PM400 sensor?
No. The supplied PM400 data sheet, user manual and quick start guide do not publish a sensor-replacement or post-replacement calibration procedure. Obtain the approved service procedure from Macurco before changing a sensor.
What does Macurco say about replacing PM400 sensors?
Macurco documentation is not consistent on servicing the PM400. The PM400 Series Data Sheet lists field-replaceable sensors and AimSafety catalogues replacement sensors and battery packs by part number, but the PM400 Multi-Gas Personal Monitor User Manual Rev. 2.0 states that the battery and sensor should not be replaced because the PM400 is designed to be disposable, and that changing them may impair intrinsic safety and void the warranty. The PM400 Quick Start Guide states that charging or replacing the battery should be done in a safe area and that using components not authorised by the manufacturer will void the warranty. The manual's maintenance section adds that the unit should not be disassembled, repaired or modified, that only replacement parts from the supplier should be used, and that substituting components may impair intrinsic safety. Confirm the intended service path with Macurco before replacing a sensor or battery on a monitor already in service.
