5. BASIC FUNCTIONS OF THE ENTIRE SYSTEM

The cycle time via the ELBus

circuit protector is cyclically transmitted to Controller EM12D-TMB.

Figure 7: Cycle times of the system

The electronic circuit protector REX12D/REX22D can at any time be mounted side by side with a supply module or

an existing system. By closing the connector arm a voltage supply of the device is available. Also, the device is

connected to the internal ELBus

Opening the connector arm is only permitted in the OFF condition. Opening under load can dam-

age the device or cause undefined system conditions.

After plugging in a circuit protector, it will automatically be identified and parameterised if parameters are available

for the slot in question. During this procedure the cyclical data will intermittently be marked as unvalid.
