RES-5012

If the application does not require any format changes, the channel can remain set to 0. In this case, the tempera-
ture controller behaves in exactly the same way as older models where different calibration data records are not
supported.
It is possible to switch to another channel during the AUTOCAL function; however, the controller continues working
with the original channel until the AUTOCAL function has finished. The channel currently being used by the con-
troller is shown in the status information.
8.5.7
Set point
A set point of up to 300 °C or 500 °C is allowed, depending on the selected temperature range (
"Temperature range and alloy" on page 36). If you attempt to enter a higher set point, it is limited internally to
300 °C or 500 °C.
8.6
Output data
The term "output data" refers to the data that is transferred from the RES-5012 to the EtherCAT
®
master. It con-
tains the current actual value as well as all important information on the current status of the controller. If a fault is
signaled, it can be diagnosed accurately with the help of the error code.
8.6.1
AUTOCAL active (AA)
The AA bit indicates that the AUTOCAL or AUTOCOMP function is executing.
8.6.2
AUTOCAL blocked (AG)
If the AG bit is set, the AUTOCAL function is temporarily blocked. This is the case if "START" is active or the heat-
sealing band is still in the cooling phase.
8.6.3
Alarm active (AL)
If the AL bit is set, an alarm has been triggered but not yet reset. The error code provides information on the exact
cause (
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 achieved (TE)
The TE bit is set if the actual temperature exceeds 95% of the set temperature. This status bit is reset again as
soon as you exit control mode (ST bit = 0) or a fault is signaled (AL bit = 1).
8.6.6
Temperature OK (TO)
The RES-5012 checks whether the actual temperature is within a settable tolerance band ("OK" window) either
side of the set temperature. The high (
) and low (
) limits of the tolerance band can be changed inde-
pendently of one another in the parameter data (
section 8.7 "Object dictionary" on page 30). The following set-
tings are possible:
1.
"Off"
The TO bit is always reset.
2.
"Active when Tact = Tset" (factory setting)
The TO bit is set if the actual value is inside the specified temperature tolerance band. If the actual temperature
