    Type ME24 Displayelements 10.7.1 Display of device status The LED for device status and the NAMUR light element changes color in accordance with NAMUR NE 107. If several device statuses exist simultaneously, the device status with the highest priority is displayed. The priority is determined by the severity of the deviation from controlled operation (red LED = failure = highest priority). Status display in accordance with NE 107, edition 2006-06-12 Color Color Code Description Meaning Failure, error or fault Due to a malfunction in the device or on its periphery, controlled operation is not possible. Orange Function check The device is being worked on; controlled oper- ation is therefore temporarily not possible. e. g. Operating mode HAND or simulation. Yellow Outside the specification The ambient conditions or process conditions for the device are outside the specified area. Blue Maintenance requirement The device is in controlled operation, however function is briefly restricted. → Maintain device. Green Diagnostics active Device is operating faultlessly. Status changes are shown in color. Messages are transmitted via any connected field bus. White Diagnostics inactive Device is switched on. Status changes are not shown.

Securing the cables (strain relief): To relieve the strain, fix the cables to the recess with a cable clip. Recess for securing the cables Figure 27: Strain relief for cables, I/O module Type ME24 11.3 Replacing the memory card The I/O module ME24 has a removable data storage in the form of a memory card on which the device-specific data is stored. On modules 2AO, 2DO and 4DO this memory card is a micro SD card. On module 2AI, 2DI a Micro SIM card. The device is delivered with the memory card inserted. The memory card can be used to replace specific data on devices which have the same identification number. For example, for transferring the data from a defective device to a new device. The memory card stores e.g. the baud rate, the address and/or the configuration of the device process values. If there is device-specific data on the inserted memory card during the restart, the device will take over this data. If there is no device-specific data on the memory card, the device will store its own data on it. NOTE! Do not use a standard memory card for the device. Purchase the memory card for Type ME24 from your Bürkert sales department. See chapter “12 Accessories”. The micro SD card must be formatted with the FAT12/16/32 file system. If this is not the case, the card will not be detected when it is inserted. Replacing the memory card: The memory card is on the underside of the device. 1. Take safety measures: → Switch off supply voltage! 2. Remove I/O module Type ME24 from the backplane Type BEF1.
