This document mainly introduces the use instructions of ATS-34 automatic transfer switch controller, including installation, operation and maintenance
The ATS-34 is a microprocessor-based controller designed to manage automatic transfer between two backup generators in a redundant system. It features a touch screen interface, programmable settings for duty cycle and transfer timing, and monitoring of voltage and frequency for both generators. The manual details operation modes including AUTO, OFF, and Bypass, along with panel controls and LED indicators for status and alarms.
Installation instructions cover panel cut-out, unit dimensions, and typical wiring. Programming is done via the front panel, with options for remote control via USB, RS485, or Ethernet. Settings are auto-saved and include adjustable time delays for transfer, cool-down, and OFF position, as well as voltage and frequency thresholds.
| Adjustable Duty Time Range | 0 — 250 Hours |
|---|---|
| Adjustable Transfer Time Delay | 0 — 250 sec |
| Adjustable Cool-Down Time Delay | 0 — 250 sec |
| Adjustable OFF Position Time Delay | 0 — 99 sec |
| Over Voltage Range | 110 — 520 Vac |
| Under Voltage Range | 80 — 470 Vac |
| Over Frequency Range | 51 — 75 Hz |
| Under Frequency Range | 40 — 59 Hz |
It can operate in AUTO mode (automatic transfer), OFF mode (disables all functions), and Bypass mode (manual override to force transfer).
Yes, it supports remote programming via USB, RS485, or Ethernet (mobile proxy) communication.
