Automatic Load Transfer Controllers ATS1.1 /1.0 ENKO Electronic Control Systems - IZMIR / TURKIYE Automatic Load Transfer Switches: ATS1.1 and ATS1.0 ATS1.1 and ATS1.0 are dedicated ATS1.1 and ATS1.0 are both Load Transfer Control Switches, which Load Transfer Control switches, monitors the Mains Bus-Bar voltages and transfer the load if the voltage limits fall beyond required tolerances. These units can be used which allow independent control of with any two voltage bus-bars, where the load is required to be controlled according to their availability. All three phase voltages are monitored on the mains bus-bar side and each phase can have independent upper and lower voltage limits. ATS1.0 is a basic Transfer Control Switch, where only the basic control functions are required with no auxiliary input or output functions. ATS1.1 is on the other hand, designed with 2 auxiliary outputs and 3 auxiliary inputs. These i/o ports can be configured from the device menu for peripheral device control. The units allow the user to crank the generator on for testing or periodical maintenance. This test function can be executed with or without load transfer, allowing testing for the transfer switch at the same time. Normal system operation is maintained in the Automatic mode. During operation, mains or generator phase voltage can both be monitored on the controller display, hence avoiding extra AC voltmeters to be used on the panel. All voltage values are displayed in True RMS values with high reading accuracy. All unit parameters can be adjusted from the device configuration Main features: 3 phase mains voltage single phase generator voltage monitoring and measurement 3 digit LED display for voltage readouts and parameter displaying 5 configurable i/o ports for engine and system controls Full LED indicators for busbar status condition indication AUTOMATIC, TEST on-load and TEST off-load operation modes Full digital calibration of all analog measuring variables Load transfer function on Mains Frequency monitoring load from either Mains or Generator menu and all program parameter values can be seen on the controller display. The units can also be programmed to control the engine cool- Small mechanical outline for minimal control applications bus-bars, whichever is available, with mains bus-bar priority. down function, hence allowing simple engine starter units to be used with small capacity generator sets.
