System Architecture & Signal Flow
The DSE4620 MKII operates as the intelligence layer in a two-source ATS system. It continuously monitors both the mains (utility) supply and the standby generator output across all three phases. Upon detection of a mains failure event (voltage or frequency outside configured thresholds), the module initiates a configurable start sequence for the generator, monitors generator readiness, then commands the transfer contactor to switch the load from mains to generator. Upon mains restoration and stability confirmation, the module executes a retransfer sequence and issues a generator cool-down and stop command. All timing parameters — including start delay, transfer delay, return delay, and cool-down period — are independently configurable. Digital inputs accept external signals such as remote start, load inhibit, and auxiliary fault. Relay outputs drive contactor coils, audible alarms, and remote annunciators. RS-485 Modbus RTU provides full register-level access for SCADA integration.

Technical FAQ
Q: Is the DSE4620 MKII backward compatible with the original DSE4620?
A: The MKII shares the same form factor and wiring terminals as the original DSE4620, making it a direct drop-in replacement in most panel installations. Firmware parameters may require reconfiguration via DSE Configuration Suite after replacement.
Q: What is the maximum mains/generator voltage the DSE4620 MKII can monitor?
A: The module supports sensing up to 415 V AC line-to-line (3-phase systems), covering the majority of global LV distribution standards including 380 V, 400 V, and 415 V systems.
Q: Can the DSE4620 MKII be integrated with a Modbus SCADA system?
A: Yes. The RS-485 port supports Modbus RTU protocol. The full Modbus register map is available in the DSE4620 MKII operator manual, downloadable from the DSE website or available from Konmask.com upon request.
Q: What is the typical lead time for the DSE4620 MKII?
