Description of the functions MPA 41xx Dungs

If MPA is locked (state 0), it can be unlocked by pressing the unlock key, for at least half a second or by using the 230 V unlocking input. According to DIN EN 14459 the number of possible unlocking processes is limited to 5 in 15 minutes, that means the automatic system denies further unlocking if the MPA has been unlocked more than 5 times within a short time period. Only after a waiting time during which the MPA is provided with power is it possible to unlock MPA again.
 
Extended unlocking
The described limitation to 5 unlocking operations in 15 minutes can be reset by means of "extended unlocking". To do this, the unlock key must be pressed for at least 5 seconds (max. 10 s). The "Extended unlocking" is active in all operational states of MPA, that means that a safety cut-off with restart of MPA in operation can be carried out via the "Extended unlocking" also in the presence of a flame. Extended unlocking is not possible via the 230 V unlocking input and via fieldbus modules.
 
Access level
Write access to MPA is defined on different access levels. Each parameter is asigned to a certain access level. In order to modify a parameter, MPA must be at the assigned or higher level. If the access level is not sufficient to modify a parameter, the VisionBox reports it, or a message is output on the MPA display prompting the user to enter the valid password. To change the access level, the correct password must be entered in the VisionBox. The access level is automatically reset after 5 hours or after power failure. Exception: if the automatic gas burner performs a restart during these 5 hours, these 5 hours for the current access level are counted again from the beginning. Note: after completing configuration of the automatic gas burner it is recommended to reset the access level immediately manually. The 5 levels are in order: Operator, Service, OEM, OEM Expert, Dungs.
