Automatic load detection
Long cable lengths
 | Long cable lengths The manual preselection of the operation mode (dimmer mode) is recommended if there are long cables between the dimmer terminal and load. Automatic load detection may fail, since inductive and capacitive line influences may lead to misinterpretation of the load. In addition, please note the maximum permissible cable length! |
User program
| Parameterization of the dimmer terminal on starting the PLC If you do not operate the dimmer terminal with the default values (e.g. for dimmer mode, ramp time, etc.) it is recommended to initialize the respective registers with the deviating values from the user program when starting the PLC. This saves the service personnel having to perform the complicated manual initialization when exchanging terminals and also helps to avoid undesirable error states. |
Wound transformer with no load on the secondary side
Note | |
No open-circuit transformers! The automatic load detection, which the dimmer terminal performs on the connected load when the mains voltage is switched on, fails if a wound transformer is connected that has no load connected to its secondary side. |
