MG TR-EVO, Инструкция по эксплуатации, Страница: 9 / 24

Terminals 9, 10
"IN WORK" output
Opto-isolated output of sealing circuit signaling: this optical coupler is
closed during the sealing cycle, and return open at the end of the cycle; see
the "operating modes" section for further operating details.
It can be externally configured NPN or PNP, with a maximum current
which must not exceed 50mA at 24 Volts continuously.
Pay attention on connection to polarity: terminal 9 has the positive
(collector) and terminal 10 has the negative (emitter).
Terminals 11, 12, 13
Heating and/or pre-heating start inputs
Wire to these inputs the signals for sealing cycle control: these
signals must have a voltage between 12 Vac and 24Vac or from
12Vdc to 30Vdc by applying the positive to terminal 11 and 13
and the negative to terminal 12.
In the presence of the START signal( terminal 11), the heating
element reaches the working temperature.
In the presence of the pre-heating signal( terminal 13), the
temperature is adjusted to pre-heating level.
Further details are found in the "operating modes" section.
Terminals 14, 15
Heating element voltage measurement input.
Use is preferred of the flexible, twisted cable (with strand conductors) with a 2x0.5 mm² section
with at least 15 twists per meter.
If there are multiple heating elements connected in series or parallel, the voltage is taken from
the ends of the heating elements based on the diagram outlined above.
