Power Windows
Work around the power window you actually have: note outages, restart steps, and which cuts cannot be left half-finished.
Power problems do not always look dramatic. A small voltage dip, a rushed restart or a machine brought online in the wrong order can upset drives, controllers and extraction. Power Windows explains the startup and shutdown checks that help cutting equipment settle properly on busy shop floors.
Power Windows is about the supply you truly get at the machine, not the tidy version on a planner's sheet. Record each outage, note how long the spindle or extraction stood idle, and write the restart order in plain steps.
Checks before power returns
- Outage time logged against the run
- Control screen photographed after restart alarms clear
- Drive settings and job reference written beside the machine record
- Operator and supervisor named for the handover
Use this journal note with the linked equipment pages when a cell has to recover after a dip or planned outage. The writing here deals with restart order, cut continuity, and checks that protect stock from being scrapped halfway through a sheet. It belongs beside the machine record, not buried in general admin.
Where restart order matters most
Power Windows deals with the production window you actually have, not the one the plan assumed. Note outages, list restart steps in order, and mark any cut that cannot be stopped halfway without wasting stock.
A CNC router, saw, extraction unit, compressor, and dust collection line do not all enjoy being energised in the same order. Gauteng voltage dips, coastal humidity, and municipal interruptions can all change how drives, sensors, and vacuum hold-down behave on first power-up. Write the sequence around the actual cell in Johannesburg, Durban, or Cape Town, not a generic diagram.
Mark the cuts that must never pause once started. Thin sheet, laminated board, and nested work can shift, lift, or mark if vacuum drops and the job is resumed without checking position, spoilboard condition, and tool zero. A short note pinned near the HMI often prevents a rushed restart after tea break or load-shedding.
Notes that stay useful
Keep one page that lists the outage, the restart sequence, and the jobs that can be resumed without risk. Add the tooling number, controller alarm if one appeared, and the point where the run stopped. That record is worth more than a vague memory when the next interruption arrives.
Pair Power Windows with the matching Applications note and an Edgework entry when the same machine handles different materials under uneven supply conditions. Recheck tooling, homing position, and extraction before any courier collection is booked for completed parts. Include your load-shedding stage and the control panel model when you write in through our contact form.

South African supply conditions
Planned outages, generator changeovers, and uneven municipal supply all affect how a cutting cell should be restarted. OR Tambo dispatch times and customer collection slots do not remove the need for proper checks after power returns. If a line shares supply with extraction or compressed air, note that dependency clearly.
Coastal sites may need extra attention on electrical cabinets after damp mornings, while inland workshops often fight dust on sensors and fan inlets. A machine that powers up cleanly can still cut poorly if extraction lags, vacuum has not recovered, or axis reference was skipped. First-article checks matter most after an interruption, not least.

Power-window briefing points
Work around the power window you actually have: note outages, restart steps, and which cuts cannot be left half-finished.
File this note with the machine history while the outage details, alarm codes, and restart sequence are still fresh. It should sit with the job record whenever someone asks why a run was paused, resumed, or scrapped after unstable supply.
