HIMA F7131 processor card

Spark generator connection MPA 41xx does not have a mounted spark generator. Suitable spark generators, see accessory list. Attention: A special spark generator is required depending on the electrode arrangement (single-electrode operation).Installation options for the MPA 41xx: - direct screw connection of the base on the mounting surface Break out mounting holes, e.g., with a suitable screwdriver or drill them with a drill 4.2 mm (M4) or 5.5 mm (M5). - Hat rail mounting (locking the base into place on a hat rail)

Unlocking function If MPA is locked (state 0), it can be un - locked by pressing the unlock key. Keep the key pressed minimum 0.5 s (max. 5 s) to distinguish the function from pos - sible EMC interfering impulses. The same is true for 230 V unlocking and unlocking via fieldbus modules. According to DIN EN 14459 (annex J), the number of possible unlocking proc - esses is limited to 5 in 15 minutes, that means the automatic system denies fur - ther unlocking if the MPA has been un - locked 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 the MPA again. The waiting time is 15 minutes or 3 minutes for each unlocking

Extended unlocking

 The described limitation to 5 unlock - ing operations in 15 minutes can be reset by means of "Extended unlock - ing". To do this, the unlock key must be pressed for at least 5 s (max.. 10 s) (af - ter 5 s, the display begins to flash). The "Extended unlocking" is active in all operational states of the MPA, that means that a safety cut-off with restart of the 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 dif - ferent access levels. Each parameter is assigned to a cer - tain access level. In order to modify a parameter, MPA must be in the as - signed or higher level. If the access level is not sufficient for modifying a parameter, the VisionBox reports it, or a message is prompted on the MPA display requesting to en - ter the valid password. In higher levels, the users must press a key to confirm that they are on site. The display is flashing for 30 s until a key is pressed; otherwise, the MPA remains in the pre - vious level. In order to change the access level, enter the correct password either on the display (MPA 4112/MPA 4122) or in the VisionBox → MPA settings → Ac - cess level
