Swap fault
A swap fault is indicated if the automatic download fails. In this case, the CU will return to the
parameter set previously held in the EEPROM and F00395 as well as one of F00061,
F00062 and F00063 will be generated.
On standard CUs the current parameter set needs to be checked and its correctness
confirmed by clearing F00395. This can be done via:
● Digital input or PLC signal (depends on the settings of P0700)
● Setting P7844 = 0.
● Via the key
on the BOP
In the next step F00061 / F00062 or F00063 has to be cleared via power cycle.
Note
F00395 cannot be cleared via power cycle. F00061, F00062 and F00063 can only be
cleared via power cycle.
In case of a swap fault check, whether the MMC is defective or a parameter set clone00.bin
is available or the parameter set is valid.
A valid parameter set means, it is not from a different type (e. g. CU240S DP and CU240S or
fail-safe and standard CUs)
Rules regarding a swap
There are a number of scenarios where a swap is allowed, each with their own unique set of
conditions that must be observed.
DANGER
Do not attempt to hot swap a power module (PM)
Before attempting to swap a PM it must be fully powered-down. Any attempt to swap-out a
PM when power is still applied could result in death of personnel and severe damage to
property and equipment.
WARNING
Swap restrictions
Before performing a swap it is the responsibility of the user to ensure that:
• only CUs of the same type are swapped
• the MMC contains the correct parameter set
• only PMs of the same type and power rating are swapped.
• the application is in a safe state before any swap of equipment is performed.
