4.4. Outputs
4.4.1. Actual Value Output:
The actual value output (24) supplies a voltage in the range 0-10V, propor-
tional to the heat conductor’s temperature. The voltage range relates to the selected temperature range,
i.e. 10V at the actual value output corresponds to 300°C, if the selected temperature range is 300°C. The
actual value output can supply a maximum current of 5 mA.
While the set value output is being used with a potentiometer (“R set value” setting) the actual value out-
put acts as a constant voltage source with an output voltage of 10V.
4.4.2. Message relay output:
Message relay output 1 (21) provides a NO contact, which works against
the GND contact (20). It can be set whether the contact is open or closed when the relay is actuated. The
switching capacity of the relay contact is only designed for message functions. The relay contact has
been factory-set in such a way that the relay contact is closed when the relay is pressed.
4.4.3. Control relay outputs:
The control relay outputs 1 (16/17/18) and 2 (27/28/29) each provide a
change-over contact. The switching capacity is only designed for control functions.
4.4.4. Alarm output:
The alarm output (5/6) is a relay switching contact. It can be set to determine
whether the alarm output is opened or closed, in the case of a fault. The factory setting of the relay con-
tact is “closed” when a fault occurs.
4.4.5. ELR output:
The ELR output (1/2) is used to control an external solid-state relay, which is used as
an actuator instead of the controller's internal actuator. Using the external solid-state relay, it is possible
to connect combinations of the conductor and sealing transformer to loads which are greater than internal
actuator's permitted load.
4.5. Interfaces
We will provide you with the detailed interface description of the control system with integrated PIREG-D2
resistance temperature controller for packaging machines if required.
