Changing the heating element
ROPEX recommends changing the heating element in case of:
• mechanical defects, bending or deformations
• scaled or oxidised heating element ends
• burned-in deposits
• damaged coatings, e. g. copper coating or Teflon-coating
After each change of the heating element, the zero calibration must be performed in case of a cold heating element
and cold environment (i. e. Silicon, PTFE-cover, sealing bar, among others) with the function AUTOCAL, in order
to compensate production-related tolerances of the heating element resistance.
When changing the heating element, we recommend that the underlayment is checked, e. g. Silicon profile with
PTFE-fabric band. A damaged underlayment must be replaced to ensure that the heating element functions cor-
rectly.
If a new heating element is used, the above-described procedure for burning in must be performed.
If the new heating element has a different specification, it must be ensured that the voltage applied is adjusted to
the resistance of the heating element. If the new heating element has another specification (e. g. heating element
cross section, alloy), the application must be checked (
ROPEX application report). If this specification was not
taken into account in the application report, the application report must be updated in accordance with the new
requirements.

Startup procedure
Observe here section 2 "General information" on page 5 and section 5.1 "Use" on page 11.
8.6.1
Initial startup
Requirement: Device is correctly mounted and connected (
section 7 "Mounting and Installation" on page 13).
Proceed as follows when starting up the RESISTRON
®
Temperature Controller RES-5009 for the first time:
1. Switch off line voltage and 24 VDC power supply; verify lack of voltage.
2. Selection of the CAN protocol: CANopen or ROPEX CAN
(
section 8.4 "Selection of CAN protocol" on page 24)
NOTE
The heating element must be changed in accordance with the manufacturer’s instructions.
WARNING
For changing the heating element, the supply voltage must be disconnected from the
RESISTRON
®
Temperature Controller
RES-5009 at all phases.
WARNING
The assembly, installation and startup may be performed only by technically trained and com-
petent persons. The persons must be familiar with the dangers associated with it and guarantee
provisions.
