Description of the functions

Unlocking functionIfMPAislocked(state0),itcanbeun-locked by pressing the unlock key. Keep thekeypressedminimum0.5s(max.5s)todistinguishthefunctionfrompos-sible EMC interfering impulses.Thesameistruefor230Vunlockingandunlockingviafieldbusmodules.

According toDINEN14459 (annexJ),the number of possible unlocking proc-essesislimitedto5in15minutes,thatmeans the automatic system denies fur-therunlockingiftheMPAhasbeenun-locked more than 5 times within a short time period. Only after a waiting time duringwhich theMPA isprovidedwithpower is itpossible tounlock theMPAagain.

The waiting time is 15 minutes or 3minutes for each unlocking.

Extended unlockingThe described limitation to 5 unlock-ing operations in 15 minutes can bereset by means of "Extended unlock-ing".Todothis,theunlockkeymustbepressedforatleast5s(max..10s)(af-ter5s,thedisplaybeginstoflash).

Attention

ThemountingoftheEM2/6modulesmustonlytakeplacebyDUNGSorbythirdpartiesauthorisedbyDungs.

Functions

Relay outputs as a function of state:

Asafunctionoftheprogramstate,the relay contacts are closed or opened.Theexternallyappliedvolt-age is switched to random consum-ers.

Application-Signallingofoperationalstates-Activationofanalogueactuators

Byusinganalogueactuators,twoposition messages can be reported totheEM2/6.

PWM signal for activation, for ex-ample, of speed-controlled fans.

ThePWMsignalcanbemodulatedduring the "operation" state by apply-ingamainsvoltagesignal.The speed is controlled with no speed feedback.

Analogue output for current / voltage

Thecurrentsignal(4-20mA)orthevoltagesignal(0-10VAC)canbemodulatedbyapplyingamainsvolt-age signal.
