Initial Inspection & Subsequent Checks Of The Kiln System; Connecting The Control Unit - Rohde ELS-N Manuel D'utilisation Original

7.2. Initial inspection & subsequent checks of the kiln system
⇒ You must carry out the initial inspection after commissioning but before starting the firing operation.
⇒ You must carry out the test before restarting the kiln or if the kiln has not been used for a long time.
⇒
In the case of commercial use, the kiln and the control system must be checked by a qualified electrician for
proper and perfect condition in accordance with DGUV regulation 3 or the corresponding national regulations
of the operating country before the first commissioning and at the appropriate interval.
⇒
Make sure that no unauthorised persons are in the work area during the test.
⇒ Indicate that checks are being carried out (e.g., with a sign) on the kiln or kiln door.
Perform the following checks before commissioning or recommissioning:
General inspection
1. Has the kiln been delivered complete and undamaged?
2. Correct installation according to documentation and attachment to the floor.
3. Are all parts of the kiln functional and properly connected?
4. There are no foreign objects on or in the kiln.
5. Is the exhaust air duct attached correctly?
6. Is the required protective equipment correctly installed and working?
7. Is the kiln correctly connected to the power supply?
8. Is the power plug properly engaged or locked?
9. Do the connected values of the kiln match the local power grid as stated on the nameplate?
10. Are the protective conductor and equipotential bonding line adequately designed and correctly
connected?
11. Is the control unit correctly connected to the kiln?
12. Has the control system bracket been correctly installed and is it sufficiently far away from hot surfaces?
13. Are all other electrical cables OK?
Table 16: General inspection
Ensure that the following protective systems, in particular, are functional:
Mechanical protection systems check
1. Correct fit and function of the protective systems.
2. Correct attachment of the warning signs.
3. Observance of the traffic routes on-site (e.g., industrial trucks).
4. Sufficient clearances at the operating location.
Table 17: Mechanical protection systems check
Electrical protection systems check
1. The perfect, functional condition of the circuit breakers/safety contactors/switching relays.
2. Check the safety-relevant inputs and outputs used.

Connecting the control unit

The control unit is connected to the kiln via a 14-pin plug-in screw connection with a bayonet lock (CPC-14).
The black socket provided for this is located on the back wall of the kiln or the back wall of the switch box mounted on
the kiln.
