RES-5012
Version 2
is outside of the tolerance band, the TO bit is reset (see graph below).
Unlike the "Temperature achieved" status bit (TE bit), the actual temperature is evaluated independently of the
control mode.

"Active when Tact = Tset" with latch function
A heatsealing cycle starts when the ST bit is set. The TO bit is set when the actual temperature reaches the
temperature tolerance band for the first time during a heatsealing cycle. If the actual temperature leaves the
tolerance band again while the ST bit is still set, the TO bit is reset (Fig. a.). If the actual temperature does not
leave the tolerance band while the ST bit is still set, the TO bit is not reset until the start of the next heatsealing
cycle (latch function, Fig. b.). The switching state of the TO bit can thus be queried after the ST bit has been
reset and before the start of the next heatsealing cycle.
The limits of the tolerance band are adjustable up to a maximum of
±
99 K.
8.6.7
Control active (RA)
The RES-5012 has successfully accepted the "START" request and entered control mode if the RA bit = 1.
