Fans, motors & electrical supplies
Motor supplies, isolators, fan connections and electrical investigation of plant supply faults.
Services / Mechanical electrical support
Ventilation / Mechanical Electrical Support
Electrical and controls support for commercial ventilation and mechanical building-services plant in operational buildings.
Mechanical electrical support
Mechanical plant only works when the electrical and control path works with it.
ElectroLogic supports the electrical supplies, control components, interfaces and fault diagnosis that allow mechanical plant to operate. Specialist mechanical or refrigeration input is coordinated where required.
Scope of support
Six areas of mechanical electrical support.
Contactors, overloads & motor protection
Contactors, thermal overloads, protective devices and related motor-control components.
Inverters & variable-speed drives
Electrical connections, control inputs and fault investigation around VSDs and inverters.
AHU, FCU & ventilation controls
Electrical controls, sensors, signals and connected components serving air-handling and fan-coil equipment.
BMS, fire-alarm & control interfaces
Agreed BMS, fire-alarm and control interface wiring for plant and ventilation responses.
Electrical fault finding & remedial works
Traceable checks of the supply and control sequence, followed by agreed electrical repairs or replacements.
Mechanical electrical sequence
Follow the control sequence to the plant response.
When mechanical plant does not operate, the fault can sit anywhere through the electrical and control sequence—not necessarily in the motor itself.
Follow the path. Verify the response.
- 01
Demand
A timer, sensor, BMS or local request calls for operation.
- 02
Control
The relevant control signal is received and processed.
- 03
Protection
Protection and motor-control components permit safe operation.
- 04
Drive
A contactor, starter or drive provides the required motor output.
- 05
Motor
The fan or connected plant receives electrical power.
- 06
Airflow
The resulting plant response can be checked against the expected operation.
Plant support follow-up
Prove the demand. Trace the electrical path. Verify the plant response.
- 01
Prove the demand
Confirm the call for operation, relevant signals and the intended operating condition.
- 02
Trace the electrical path
Check controls, protection, drive, motor supply and agreed interfaces in sequence.
- 03
Verify the response
Record the electrical findings, completed remedial work and plant response or specialist follow-up.
