RES-5006
Version 1
The actual temperature is hereby evaluated independently of the control mode, in contrast to the “Temperature
reached” (TE bit) status bit.
3.
“Active when Tact = Tset”, with latch function
A sealing cycle begins with setting of the ST bit. The TO bit is set if the actual temperature reaches the tem-
perature monitoring band for the first time within a sealing cycle. If the monitoring band is left again - while the
ST bit is still set - the TO bit is reset (see Image a.). If the actual temperature no longer leaves the monitoring
band - while the ST bit is still set - the TO bit is not reset until the start of the next sealing cycle (latch function,
see Image b.). The switching status of the TO bit can thus be queried after resetting of the ST bit and before
the start of the next sealing cycle.
The TO bit can only be set over the parameter data in the PROFIBUS master (also over DPV1). Setting over the
ROPEX visualisation software is not possible.
The tolerance limits can be set up to max. ±99 K.
8.6.7
Regulation active (RA)
The RES-5006 has successfully accepted the START request and is in the control mode when RA bit = 1.
8.6.8
Prefix (VZ)
The prefix bit displays in the compact protocol whether the actual value is positive or negative.
