Sandustry Logic Timer Guide: How to Delay a Signal
Quick answer
A timer is a repeatable signal-delay pattern: trigger input, hold or route the signal through logic pieces, then release it to the machine after the delay you need.
Quick answer
Sandustry does not need a special “Timer” building to make delayed automation. Build a small logic cell that accepts an input signal, holds or repeats it through logic components, then sends the output after the delay.
Start with a simple goal: press a button → wait a few seconds → activate the output once. After that works, expand it into loops, pulsed doors, overflow valves, or throughput controllers.
What a logic timer needs
| Part | Job |
|---|---|
| Signal Button or Sensor | Starts the timer |
| Signal Linker | Connects the input to the logic cell |
| Repeater or chained logic | Creates delay or signal propagation steps |
| Toggle / T-FlipFlop | Holds a state when you need on/off memory |
| Logic gates | Combine conditions such as “input active and storage not full” |
| Output machine | Door, filter, lamp, launcher, pump support, or other controlled target |
The official roster includes Signal Linker, Signal Switch, Signal Button, Signal Sensor, Pulse Sensor, Presence Sensor, Buffer, Toggle, Signal Lamp, logic gates, and Repeater. Use this guide as a layout pattern, then verify exact behavior in your current build.
Simple delay pattern
- Place a Signal Button or Sensor as the trigger.
- Link it into a short line of repeaters or gate steps.
- Put a Signal Lamp at the end while testing.
- Press the trigger and count the delay before the lamp changes.
- Add or remove delay steps until the timing is close.
- Replace the lamp with the real output only after the test is repeatable.
The lamp test matters. It lets you debug the signal without also debugging a clogged factory lane.
Timer uses
| Use case | Why delay helps |
|---|---|
| Throughput controller | Release material in pulses instead of one giant clog |
| Filter reset | Let blocked material clear before reopening a route |
| Door or gate | Give the player or critters time to enter before closing |
| Burner cycle | Pulse material into heat rather than overfeeding it |
| Pump support | Avoid sending output into a full basin |
Troubleshooting
Nothing happens
Check the Signal Linker first. If the test lamp does not respond, the timer is not connected or the trigger is not producing a signal.
The output fires instantly
The output is connected before the delay section. Move the output link to the end of the timer chain.
The timer stays on forever
You probably built state memory with a Toggle but did not add a reset path. Add a second signal or condition to turn it off.
The factory still clogs
The timer is working, but the material pulse is too large. Reduce the open time or add a physical throughput limiter before the controlled lane.
