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

22 KEY:ENTER
Description:
The acknowledgement signal is transferred to the control unit. This option
is only usable in case of errors, which produce a message on the display of
the MDC. You can respond with a serial command. Then the function is
identical to pressing the [enter]-key on the keypad.
Example:
Input:
KEY:ENTER
Result:
The ENTER signal is send.
Return:
OK (no other reaction of the MDC)
23 KEY:ESCAPE
Description:
The ESCAPE signal is transferred to the control unit. This option is only
usable in case of errors, which produce a message on the display of the
MDC. You can respond with a serial command. Then the function is
identical to pressing the [esc]-key on the keypad.
Example:
Input:
KEY:ESCAPE
Result:
The ESCAPE signal is send.
Return:
OK (no other reaction of the MDC)
24 HELP
Description:
Shows a list with all RS-232C commands.
Example:
Input:
HELP
Result:
List with all RS-232C commands.
Return:
List with all commands
25 LCD? LCD? = Liquid-Crystal Display Query
Description:
Use this command to externally inspect the current content of the screen.
Example:
Input:
LCD?
Result:
When sending this command immediately after switching
ON, the content of the screen will be “READY”.
Return:
„READY“
