5.2.2
Start-up of the HC8X
1.
Ensure that there is no supply voltage at the HC8X.
2.
Unscrew two screws from the case cover.
3.
Remove the case cover and pull off the ground conductor.
4.
Set the HC8X to the "Norm" mode (see Chapter 5.1.1 Setting the HC8X Mode, page 5-
5.
If one or several control channels were set as followers, check the correct assignment
of the temperature sensors (PT100) to the controlling channel
(see Chapter 4.5 Configuring the Control Channel as a Follower, page 4-30).
6.
Check whether the correct poles of the PT100 temperature sensors are connected to
the X10 terminal strip (see Chapter 3.4 Connecting the Temperature Sensors, page 3-
7.
Check whether the correct poles of the heating circuits are connected to the clamping
strips X2 to X8 (see Chapter 3.3 Connecting the Heating Circuits, page 3-22).
8.
Check the connection of the supply voltage to the power electronics (terminal strip X9)
(see Chapter 3.2 Connecting the Power Electronics Supply Voltage, page 3-21).
9.
Check the preset value of the supply voltage to the control electronics in the indicator
window of the socket.
10. If the set voltage differs from the required voltage: Preselect the supply voltage (see
Chapter 3.6.1 Supply Voltage and Fuse Preselection, Primary Side, page 3-25).
11. Check the optical fiber connection of the HC8X (see Chapter 3.5 Connecting the Optical
12. Connect the ground conductor with flat plug contact in the case cover and check correct
seating.
13. Close and screw on the case cover.
14. Connect the supply voltage for the control electronics and insert the plug in the socket.
15. Connect the supply voltage for the power electronics.
5.3
Start-up of the Process
1.
Perform the configuration query of the measuring system PC (see Chapter 4.3.2 Con-
figuration Query of HC8X with HC8XINIT.EXE, page 4-27).
2.
If the HC8X does not reply: Check the communication between the measuring system
PC and the HC8X (see Chapter 1.3 HC8X Process Connection, page 1-16).
3.
Check whether the control behavior is correct. For this purpose, read the actual values
of the PT100 temperature sensors on the measuring system PC and observe the be-
havior of the respective actuator (see Chapter 5.4 Control Process, page 5-34).
