PLEASE READ NOW AND TAKE ACTION
Dear MSA Customer,
MSA is issuing this User Safety Notice to inform you of a PROCEDURAL UPDATE regarding usage of the Altair 5X PID gas detector.
MSA has determined that PID sensors manufactured from March 2020 to and including June 2023 may not respond to gas after being turned on due to the lamp of the sensor not lighting upon startup and the Altair 5X PID will not display a PID lamp error.
To verify the proper operation of the Altair 5X PID, perform a BUMP TEST OR MANUAL GAS CHECK each time the unit is turned on and prior to using the device.
MSA has not received any reports of injuries due to this condition. However, it is necessary that you perform the actions outlined in this notice.
To verify proper device operation, PID sensors manufactured from March 2020 to and including June 2023 must have a bump test or manual gas check performed each time that the unit is powered on, prior to use. This requirement is in addition to existing usage guidelines.
To reduce the number of bump tests required during daily usage, you may leave your Altair device operating continuously in between uses. Manual gas checks may be performed as a substitute for the bump test if it is not convenient to perform a bump test, for example if a Galaxy GX2 Automated Test System is not nearby. The manual gas check procedure is detailed in Appendix A of this notice.
The Altair 5X PID Instruction Manual has been updated to Revision 08 reflect these changes.
Affected Date Range PID sensors manufactured from March 2020 to and including June 2023 are affected and must be used in accordance with this updated guidance.
PID sensors manufactured prior to March 2020 are not affected and may continue to be used without any procedural changes.
Instructions to identify your product and date of manufacture are included in this notice.
| MSA is advising Altair 5X PID customers with PID sensors manufactured from March 2020 to and including June 2023 to perform a bump test or manual gas check each time the unit is turned on prior to using the device. |
