0BFAULT SIGNALS
9.1 General
All plant components or plant-functions which are necessary or indispensable for the process are supervised by the PLC system.
9.2 Indicating of Faults
Malfunctions are indicated visually and audibly on occurrence.
Whenever a fault comes up, a horn sounds and a red flashlight is flashing.
Each furnace is equipped with a RESET button at control cabinets. After taking notice of a fault signal the operator can cancel the horn sound by pressing the RESET button. Furthermore alarm messages are displayed in the belonging OIP-system and must be confirmed in the system.
The ALARM box visible on all Process Pictures shows the number of actual faults. Double click on the box leads to the ALARM MESSAGE window. Here only active alarms are visible.
In the ALARM HISTORY window active and gone alarms are listed.
9.3 Eliminating of Fault Causes
Eliminating of fault causes are only allowed by trained personnel. Work with electricity must be carried out by specially trained and qualified personnel like electricians. ORDER – READ THE INSTRUCTIONS
Pay attention to the instructions, especially the chapter general safety instructions in these operating instructions!
ORDER - SWITCH OFF THE VOLTAGE SUPPLY If work at or near electrical devices or the melting devices are necessary, switch off the voltage supply at the main switch.
ORDER – WEAR PROTECTIVE EQUIPMENT
Wear the necessary protective equipment like hard hats, protective shoes, dust mask and goggles.
