7.3 Meaning of the letter X in the type test certificate
The specific circumstances for which the X is added to the end of the test report numbers are as follows:
- Switching operations may be performed on the intrinsically safe electrical circuits only when the JUMO safetyM STB/STW
Ex, including all supply lines, is de-energized.
-The JUMO safetyM STB/STW Ex, including all supply lines, may be energized only when the cover cap of the intrinsically
safe electrical circuits has been properly fitted.
v Chapter 4.2 "Removing the cover cap"
- The probes from JUMO based on JUMO data sheets 901006 and 902006 that are included in the ATEX test report do not
feature reliable isolation of the sensor from the fitting. As a result, the sensor connections are to be considered grounded
for the safety assessment according to ATEX. This means that the user must ensure that during connection of the intrinsi-
cally safe electrical circuit through integration in the local potential (e.g. potential equalization or FB), the intrinsic safety of
the JUMO safetyM STB/STW Ex is not reversed.
- The probe connection heads of the considered probes do not meet the requirements for material composition from EN
60079-0 for EPL Ga. Therefore, corresponding impact protection must be provided at the site for use in EPL Ga.
v Chapter 9.12 "Important information for the probes in Chapter 9.13 to Chapter 9.15"
- Only the STB (safety temperature limiter) variant of the JUMO safetyM STB/STW Ex is admissable for use as a safety de-
vice for minimum overpressure monitoring with static pressurized enclosure.
- The switch-off limit value must be set in accordance with the application so that no dangerous state can arise when taking
into account accuracy, fault tolerance of the JUMO safetyM STB/STW Ex, and (if applicable) pressure or temperature over-
shoot.
- The safety-relevant settings of the JUMO safetyM STB/STW Ex must be protected against unauthorized changes (e.g. with
sealed or password-protected inputs).
- For use of the JUMO safetyM STB/STW Ex in the STW (safety temperature monitor) variant, it must be ensured that after a
switch-off by the temperature limiter an automatic restart of the monitored equipment is prevented by a higher-level control
system.
