Industrial Applications

1. Conveyor Belt Delay Start Control

Ensuring sequential startup of multiple cascading conveyor belts in industrial material handling facilities to prevent overall grid inrush current overload.

Problem Solved

Starting multiple conveyor motors simultaneously draws high inrush currents that can trip main circuit breakers. Configured in ON-delay mode (Mode A) with the DPDT relay output, the timer staggers downstream conveyor starts.

2. CNC Machine Guideway Lubrication Cycle

Controlling periodic automatic lubrication intervals for machine tool axes or reciprocating linear guideways.

Problem Solved

Over-lubrication wastes expensive lubricant and causes mess, whereas under-lubrication leads to rapid wear. Employing Flicker OFF start (Mode B) or Flicker ON start (Mode B2) allows automatic repeating ON/OFF cycles of the lubrication pump across a wide time range.

3. VFFS Heat Seal Jaw Dwell Time Control

Managing the exact duration of heat-sealing jaw activation on vertical form-fill-seal (VFFS) packaging machines.

Problem Solved

Inconsistent heat activation yields bad packaging seals or melted plastic. Operating in One-shot mode (Mode J) and triggered by a PNP registration sensor, the timer energizes the seal element for a sub-second, highly precise duration independent of trigger pulse length.
