User alarms

The Dryer is equipped with a user alarm input (terminals 51 and 66 of Dryer's ter-
minal board), useful to detect and signal a specific alarm condition, depending on
the user's needs. The user alarm is completely programmable in effect on Dryer's
operation, intervention delay, and reset mode.
S Parameter B12 selects the effect of user alarm intervention on Dryer's operation;
if its value is "run", the Dryer continues to work, and the alarm condition is only
signalled activating the alarm relay; if its value is "StoP", the Dryer stops.
S Parameter B13 allows a delay for the alarm intervention to be programmed (in the
range 0 --- 600 secs.).
S Parameter B14 selects the reset mode of user alarm, and has meaning only if the
effect is "StoP"; if its value is "Auto", the Dryer automatically restarts when the
alarm cause has been resolved; if its value is "MANUAL ", the alarm must be man-
ually reset (either through the button "alarm reset" or the input "remote reset",
terminals 51 and 64) for the Dryer to restart.
