2.
Ensure that the sensor is properly mounted in a vertical orientation with the sensor facing down. When
applying Teflon tape, do not apply to all threads - only use enough to make a good seal (covering
about ½ the threads is sufficient). A metal to metal connection is required to ensure earth ground
continuity for electrical safety.
3.
Use ¾” NPT plugs properly rated for hazardous locations to block any unused connections
4.
Removal of the Junction box cover or threaded sensor housing (399-800000-000) violates the Ex d
protection method and hence power must be removed from the sensor prior its safe removal.
5.
Proper precautions should be taken during installation and maintenance to avoid the build-up of static
charge on the plastic components of the sensor. These include the splashguard and splashguard
adapter.
6.
Do not operate the sensor outside of the stated operating temperature limits.
7.
Do not operate the sensor outside the stated operating limits for voltage supply.
8.
These sensors meet EN60079-0, EN60079-1.
Calibration/Bump Test Following Ingress Protection Events
Although the Model TP-524D/624D detector models are designed for IP 66 Ingress Protection, it is a
mandatory requirement from the ISA 92.00.01-2010 Performance Standard that this device requires that a gas
bump test or span calibration is performed shortly after any event where the conditions of IP66 level ingresses
have been presented to the detector. An example would be after an extreme wash-down event, or after
sustained and concentrated dust exposure event. In these cases, the unit must be confirmed to be reading
accurately before safe operation is restored.
NOTE
: It is mandatory to bump test or span calibrate the detector following field situations
where exposures to IP 66 level ingresses from dust or water have been presented.
