5 ADJUST:START
Description:
Sending this command causes the adjust to be executed at once. This
procedure checks on the position of the nozzle insert with respect to the
tappet. It is required during each initial start-up and after replacing the
nozzle unit.
For further information read paragraph 8.2.3, page 117.
Example:
Input:
ADJUST:START
Result:
The adjust is initiated.
Return:
Adjust Screw OUT Press Enter
6 ADJUST:OFFSET:?
Description:
This command gives the current value of the adjust offset (see
paragraph 7.12, page 75).
The value can be between -5 and 5. The value 0 means, the adjust offset is
deactivated.
Example:
Input:
ADJUST:OFFSET:?
Result:
The current value of the adjust offset is returned.
Return:
5
7 ADJUST:OFFSET:<offset value>
Description:
This command sets the value for the adjust offset (see paragraph 7.12,
page 75).
You can enter integer values between -5 and 5. With 0 you deactivate the
adjust offset.
Example:
Input:
ADJUST:OFFSET:5
Result:
The value of the adjust offset is set (here: to 5).
Return:
OK
8 ADJUST:CALIBRATION:?
Description:
This command gives the status of the (remote) adjust and the current
adjust value. The response to this command contains seven numerical
values. You can ignore the first six parameters limit at 0 %, limit at 100 %,
difference, reference value, last mean value and total value). They are only
there for our support, if there is an error with the (remote) adjust.
The last parameter sent is the adjust value in percent. Be aware that the
given value is the actual percentage value, multiplied by 10. Therefore, a
given value of 8 represents an adjust value of 0.8 %.
Example:
Input:
ADJUST:CALIBRATION:?
Result:
The status of the (remote) adjust is given, including the
current adjust value.
Return:
151285, 47623, 103662, 150836, 108654, 42182, 8
9 ADJUST:CALIBRATION:ON
Description:
This command activates the adjust, so that you can perform it as a remote
adjust.
Example:
Input:
ADJUST:CALIBRATION:ON
Result:
The adjust is activated.
Return:
Adjust ON

10 HEATER:?
Description:
This command shows the state of the heater. This includes the following
information.
• T-point of the temperature calibration
• M- point of the temperature calibration
• Maximum temperature of the connected heater (°C)
• the current target temperature (°C)
• upper limit of allowed temperature range (°C x 10)
• lower limit of allowed temperature range (°C x 10)
• current temperature (°C)
• calibration status (0 = no, 1 = yes)
• current heater status (1 = ON, 2 = OFF, 4 = not
calibrated, 5 = temperature settled in, 7 = plugged in,
8 = plugged out, 9 = calibration 20 °C, 10 =
calibration 100 °C; XXXX communication error code)
In case there is no heater connected, the response is “NAK”.
Example:
Input:
HEATER:?
Result:
Switched ON or OFF, current temperature and target
temperature and other information are given.
Return:
1000, 20000, 180, 110, 30, 20, 109, 1, 5
11 HEATER:ID?
Description:
This command shows the type and serial number of the heater.
In case there is no heater connected, the response is “NAK”.
Example:
Input:
HEATER:ID?
Result:
Type and serial number of the heater are given.
Return:
MDH-48-BY, 10UB1234
12 HEATER:OFF
Description:
The connected heater is turned off.
In case there is no heater connected, the response is “NAK”.
Example:
Input:
HEATER:OFF
Result:
The connected heater is deactivated.
Return:
OK
13 HEATER:ON
Description:
The connected heater is turned on.
In case there is no heater connected, the response is “NAK”.
Example:
Input:
HEATER:ON
Result:
The connected heater is activated.
Return:
OK

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
