5. Istruzzjonijiet Operattivi
The Lennox 95M57-100438-03 contactor operates by receiving a 24V control signal to its coil. When the control voltage is applied, the coil energizes, closing the main contacts and allowing power to flow to the connected 3-phase load. When the control voltage is removed, the coil de-energizes, opening the main contacts and disconnecting power to the load.
- Ensure the control circuit is functioning correctly to provide the 24V signal.
- Monitor the system for proper operation after initial power-up.
6. Manutenzjoni
Regular maintenance helps ensure the longevity and reliable operation of the contactor. Always disconnect power before performing any maintenance.
- Spezzjoni Viżwali: Periodically inspect the contactor for signs of wear, corrosion, or damage to the housing and terminals.
- Issikkar tat-Terminal: Check all electrical connections for tightness. Loose connections can lead to overheating and component failure.
- Tindif: Żomm il-kuntattur ħieles mit-trab u l-fdalijiet. Uża pinzell niexef u mhux konduttiv jew arja kkompressata għat-tindif.
