The DSE705 is an Auto Transfer Switch Control Module that has been designed to monitor the mains (utility) supply. When the mains (utility) power fails the module sends a start request to the generator control unit. When the generator is up and running the module transfers the load across. When the mains (utility) returns the module transfers the load back and removes the start command. The generator should then begin it's shutdown procedure. The module can be configured so that they follow the users pre-set start and stop sequences.
Main Features
Automatic mains (utility) supply monitoring
Load changeover control
Manual start
Protected solid state (PSS) outputs
Front panel mounting
Front panel programming
LED indicators
Configurable timers
Configurable outputs
Single/three phase mains sensing
Benefits
Transfer's between mains and generator power
On-site module configuration to match user requirements
Operation
The module is operated by the three push-buttons on the front:
Manual Off Load-This is used to manually start and run the engine off load. Should the mains (utility) supply fail, then the load is transferred to the generator automatically.
Manual On Load- This mode is used to manually start and run the engine on load.
Auto Mode-This puts the module into automatic mode, where it will await a mains failure. Upon detection it will send a start request to the generator control unit.
