4.1.8. Execution prevention:
If a setting or menu change is not possible, the cursor changes to a di-
agonal cross for one second to indicate this condition.
Note: During calibration and On state, most settings on the PIREG-D2 can not be changed.
4.2. Leuchtdioden
4.2.1. Power:
The green LED “Power” indicates that the mains voltage is applied to the
PIREG-D2.
4.2.2. Heat:
The yellow LED “Heat” indicates that a welding cycle is executed if the se-
quence control is switched on. If the sequence control is switched off, this
LED only signalizes the welding process itself.
4.2.3. Alarm:
The red LED “Alarm” indicates that an error is present and that the PIREG-
D2 is in the fault condition. The fault itself is shown in plain text in the Error
menu (
5.2.4.).
4.3. Inputs
4.3.1. Start inputs:
The PIREG-D2 has two Start inputs. On the one hand, there is the Start input (3) in
which the control operates with an external voltage. On the other hand, there is the Start-Contact input (7)
with control occurring by the input, for example, being connected to AGND (2) by a switch.
By applying the high signal to the Start input (3) or applying the connection of the Start-Contact input (7)
to AGND (2), a sealing process or a sealing cycle is started. If the sequence control is switched on and
the “Start” monitoring function is deactivated, a sealing cycle will only be started with rising edge.
If the normal temperature coefficient correction is selected during calibration via eight points, the correc-
tion process is also controlled by the Start inputs, during manual operation. The single-point temperature
coefficient correction is also controlled by the start inputs.
4.3.2. Preheat inputs:
The PIREG-D2 has two preheat inputs. On the one hand, there is the Preheat
input (22) in which the control operates with an external voltage. On the other hand, there is the Preheat-
Contact input (19) with control occurring by the input, for example, being connected to AGND (2) by a
switch.
If there is a high signal applied to the Preheat input (22) between two sealing processes or two sealing
cycles or the Preheat-Contact input (19) is connected to AGND (2), the PIREG-D2 regulates the heat
conductor temperature to the set preheat temperature (
5.4.1.).
4.3.3. Calibration Start Input:
With a high signal at the Calibration Start input (25) in the Off and Fault
states, the PIREG-D2 switches to the calibration state. Here, the controller is adapted to the combination
of heat conductor and sealing transformer. During the controller's calibration function, the signal can re-
descend to low.
4.3.4. Reset Input:
With a high signal at the Reset input (26), the PIREG-D2 is reset to the Power On
state in the event of a fault even without switching off at the mains.
The following two input functions can be configured independently for each of the four inputs of the
PIREG-D2 instead of the above basic function (
5.6.2):
4.3.5. Measurement pause:
With a high signal at the
correspondingly configured input
in the Off state
the PIREG-D2 stops sending the measurement impulse to the sealing transformer. Therefore it is possi-
bly to work at the head conductor circuit without to generate an error. (from V1.00/1.23/1.30/1.25)
4.3.6. Calibration switching:
With a high signal at the
correspondingly configured input
in the Off state
the PIREG-D2 change from calibration 1 to the calibration 2. With a low signal the PIREG-D2 change
back to the calibration 1. (from V1.00/1.23/1.30/1.25)
4.3.8. Set value input:
At the set value input (23) the temperature set value may also be set, as an alter-
native to setting the set value in the PIREG-D2's display unit. An analogue voltage is used for the setting
at the set value input. The selection regarding which setting possibility should be used for the temperature
set value is made in the display unit (
5.7.5.) or by command.
- Internal:
The set value is set in the PIREG-D2's display unit (
5.2.)
- U set value:
Set the temperature set value with an analogue voltage. The voltage set value range is 0-
10V. The only selected temperature range is linearly imaged to the maximum set-value voltage , i.e. 10V
at the set value input corresponds to 300°C, if the selected temperature range is 300°C.
- R set value:
The temperature set value is set by a potentiometer. in the case of the potentiometer, the
cutter is linked to the set-value input (23), the CW connection to the actual value output (24) and the
CCW connection to the GND connection (20). In this setting, the actual value output operates as a refer-
ence voltage source with an output voltage of 10V. Pay attention to the direction of rotation when con-
necting the potentiometer. In the case of clockwise rotation on the potentiometer, the voltage should in-
crease at the set value input. The chosen temperature range is imaged to the set value voltage, as de-
scribed above.
