To prevent unintended changes to the set parameters, the JUMO safetyM STB/STW must be sealed according to Chapter 5.8
of this Operating Manual or a keypad lock or level inhibit must be used according to Chapter 8.4.
7.6 Monitoring of potential ignition sources "b" according to EN 13463-6
7.6.1 Function of the ignition source monitoring
Equipment in a non-electrical device that can be used with installation of sensors to identify developing operating statuses that
could potentially trigger ignition of the surrounding atmosphere. Before the potential ignition source can become active, appro-
priate preventive measures are implemented. These preventive measures may be implemented automatically through a direct
connection between the sensors and the ignition protection system or, in the case of the 1-sensor variant (ignition prevention
level 1 (IPL 1)), manually upon issue of a warning to the device operator.
7.6.2 Ignition prevention level (IPL)
EN 13463-6 contains two ignition prevention levels: IPL 1 and IPL 2. The application of the ignition prevention levels is shown
in Table 1 of EN 13463-6. Use of IPL 1 and IPL 2 depends on the category and the occurrence of potential ignition sources. In
accordance with this, in category 1 (zone 0) for example, potential ignition sources must be monitored during a predictable
fault with IPL 2. If the potential ignition source becomes dangerous only during an uncommon fault, ignition prevention level IPL
1 is sufficient. Monitoring of a potential ignition source that may be dangerous in standard operation is not admissable for cat-
egory 1. In this case, the concept for the apparatus must be revised. The required ignition prevention level must be determined
according to Table 1 of EN 13463-6.
7.6.3 Identification marking
An ignition prevention system that is delivered separated from the apparatus to be monitored must be marked with (b1) or (b2)
according to EN 13463-6. Here, (b1) indicates IPL 1 and (b2) indicates IPL 2.
7.6.4 Application in the 1-sensor variant
As shown in Table 1: "Achievable SIL" in Chapter 6.6 "Connection possibilities of the sensors (SIL)" of this Operating Manual,
the JUMO safetyM STB/STW Ex evaluation unit is always structured in the same way and its architecture always has a 1oo2D
