Description of the flow diagram – MDR90B

The requirements for controlling FCB 58 or FCB 53 are:

• An error-free state of the regenerative module
• The precharge inhibit must be deactivated (bridge at X13 PCE closed).

An automatic process is started if FCB 58 is activated by the customer (binary control or via process data). During this process, precharging is started, various functions are checked, and the line contactor is switched on. When the message "MDR DCL ready" is issued (DO00/PI1/0), the automatic sequence is ended and the MDR is ready for operation.

In order to deactivate the regenerative module, activation of FCB 58 must be canceled by the customer.
