8.5.8
Setpoint
Depending on the selected temperature range (
section 8.7.1 "Temperature range and alloy" on page 33), the
setpoint can be specified up to 300°C or up to 500°C. With larger setpoints, there is an internal limitation to 300°C
or 500°C.
8.6
Output data
These are the data transmitted from the RES-5006 to the PROFIBUS master. They contain the current actual
value and all important information about the current status of the controller. In case of alarm, an exact error diag-
nosis can be performed using the error number.
8.6.1
Autocal active (AA)
The AA bit shows that the AUTOCAL function is currently being executed.
8.6.2
Autocal blocked (AG)
If the AG bit is set, the AUTOCAL function is currently blocked. That is the case when START is active or the
heating element is still in the cooling off phase.
8.6.3
Alarm active (AL)
If the AL bit is set, an alarm was triggered and not reset yet. The error number provides information about the exact
cause of the error (
section 8.19 "Error messages" on page 50).
8.6.4
Warning active (WA)
This bit can be set in addition to the AL bit. If the WA bit is set, a warning is output to indicate the current fault. In
this case, the alarm relay is not active.
8.6.5
Temperature reached (TE)
The TE bit is set when the actual temperature has reached 95% of the setpoint temperature. As soon as the control
mode is ended (ST bit = 0) or an alarm occurs (AL bit = 1), this status bit is reset.
8.6.6
Temperature OK (TO)
The RES-5006 checks whether the actual temperature lies within a settable “good window” tolerance band around
the setpoint temperature. The lower (
) and upper (
) tolerance band limit can be changed separately
through the parameter data (
section 8.7 "Parameter data" on page 32). The following settings are possible:
1.
“Off”
The TO bit is always reset.
2.
“Active when Tact = Tset” (factory setting)
The TO bit is set when the actual temperature is within the set temperature monitoring band. If the actual tem-
perature is outside the monitoring band, the TO bit is reset (see following graphic).
