14 HEATER:TEMP:<target temperature>
Description:
This command changes the target temperature of the heater.
The value has to be entered as degree centigrade, e.g. 100 = 100 °C. The
target temperature value has to be between 1 °C and 230 °C.
In case there is no heater connected, the response is “NAK”.
Example:
Input:
HEATER:TEMP:60
Result:
The target temperature of the heater is set to 60 °C.
Return:
OK
15 HEATER:LIMITS:<min>,<max>
Description:
With this command you set the lower and upper limit for the temperature
regulation. The parameters say, by how many degrees the current
temperature might be below/above the target temperature, before the
MDC shows an error message. The values have to be given in 1/10
th
of a
degree centigrade, i.e. 20 = 2.0 °C.
Both parameters have to be between 5 (= 0.5 °C) and 100 (= 10.0 °C).
Information!
In case the temperature moves out of the given range, the error message
does not appear immediately. Instead it comes several seconds later. This
helps to avoid stopping the production too quickly because of a short
temperature fluctuation.
In case there is no heater connected, the response is “NAK”.
Example:
Input:
HEATER:LIMITS:10,22
Result:
The actual temperature may be 1.0 °C lower and 2.2 °C
higher than the target temperature, before an error
message is send.
Return:
OK

16 COOLER:?
Description:
This command shows the state of the cooling. This includes the following
information.
• T-point of the temperature calibration
• M- point of the temperature calibration
• the current target temperature (°C)
• offset (%)
• current actuator temperature (°C)
• calibration status (0 = no, 1 = yes)
• current cooling status (1 = ON, 2 = OFF, 4 = not
calibrated, 7 = plugged in, 8 = error PT100, 9 =
plugged out; XXXX communication error code)
In case there is no flow control valve connected, the response is “NAK”.
Example:
Input:
COOLER:?
Result:
Switched ON or OFF, current actuator temperature and
target temperature and other information are given.
Return:
1000, 20000, 45, 0, 35, 1, 1
17 COOLER:ID?
Description:
This command shows the type and serial number of the flow control valve.
In case there is no flow control valve connected, the response is “NAK”.
Example:
Input:
COOLER:ID?
Result:
Type and serial number of the flow control valve are given.
Return:
FCV-AC 6.0 M12, 101501
18 COOLER:OFF
Description:
The connected flow control valve is deactivated.
In case there is no flow control valve connected, the response is “NAK”.
Example:
Input:
COOLER:OFF
Result:
The connected flow control valve is deactivated.
Return:
OK
19 COOLER:ON
Description:
The connected flow control valve is activated.
In case there is no flow control valve connected, the response is “NAK”.
Example:
Input:
COOLER:ON
Result:
The connected flow control valve is activated.
Return:
OK
20 COOLER:TEMP:<target temperature>
Description:
This command changes the target temperature of the cooling.
The value has to be entered as 1/10
th
of a degree, i.e. 1000 = 100 °C. The
target temperature value has to be between 100 (10 °C) and 1200 (120 °C).
In case there is no flow control valve connected, the response is “NAK”.
Example:
Input:
COOLER:TEMP:750
Result:
The target temperature of the cooling is set to 75.0 °C
Return:
ON,20°C,230V
21 COOLER:OFFSET:<offset>

93
Description:
This command sets the cooler offset for the flow control valve which is
connected to the MDC. The value has to be between 0 % and 100 %. The
cooler offset allows for a constant airflow through the valve, even if the
regulation does not require an airflow yet. The value is given in percent, i.e.
allowed are integers between 0 and 100.
This command has the same function as the menu item “Cooler Offset” in
the submenu “Cooler”.
In case there is no flow control valve connected, the response is “NAK”.
Example:
Input:
COOLER:OFFSET:10
Result:
The cooler offset is set to 10 %.
Return:
OK
