Details of analog controls are provided in this Technical Requirements under Signal Definitions. GE Energy will provide separate application notes on the RS485 and I2C protocol for users to interface to the CPL RECTIFIERs. Contact your local GE Energy representative for details. Hot Plug The Rectifier is designed to accommodate rapid extraction and reinsertion into either RS485 or I2C based protocol configurations as set by the protocol pin. The protocol state of the Rectifier shall reset immediately after disengagement from the mating connector and the Rectifier will configure itself to the state set by the protocol pin upon reinsertion. Control Definitions All signals are referenced to Logic_GRD unless otherwise noted. See the Signal Definitions Table at the end of this document for further description of all the signals. Input Signals Margining: Set point of the Rectifier can be changed via this input pin. Programming can be either a voltage source or a resistance divider. The margining pin is connected to 3.3Vdc via a 10kΩ resistor inside the Rectifier. See graphs below. Module Present Signal: This signal has dual functionality. It can be used to alert the system when a module is inserted. A 500Ω resistor is present in series between this signal and Logic_GRD. An external pull-up should not raise the voltage on the pin above 0.25Vdc. Above 1Vdc, the write_protect feature of the EEPROM is enabled. Protocol Select: Establishes the communications mode of the rectifier, between analog/I2C and RS485 modes. For RS485, connect 10kΩ pull-down resistor to 54_OUT(-DC). Enable: On/Off control when I2C communications are utilized as configured by the Protocol pin. This pin must be pulled low to turn ON the rectifier. The rectifier will turn OFF if either the Enable or the ON/OFF pin is released. This signal is referenced to Logic_GRD. This function is not supported in RS485 mode. ON/OFF: This is a short pin utilized for hot-plug applications to ensure that the rectifier turns OFF before the power pins are disengaged. It also ensures that the rectifier turns ON only after the power pins have been engaged. Must be connected to V_OUT (-DC). Output Signals Power Capacity: A HI on this pin indicates that the rectifier delivers high line rated output power; a LO indicates that the rectifier is connected to low line configured for 1200W operation. Power Fail Warning: This signal is HI when the main output is being delivered and goes LO for the duration listed in this data sheet prior to the output decaying below the voltage level listed in this data sheet. Alert #: I2C interrupt signal. 3.3Vdc 10k Step granularity = 137mV -18 Vcontrol Vprogram Output Setpoint (Vdc) -53  Fan failure, OT shutdown, OV shutdown, Internal fault RS485 mode default: When the unit is powered ON in RS-485 mode the default operational state is powered ON. An RS-485 mode unit shall go to remote standby for any of the following conditions: Interlock Open, or loss of AC. RS485 mode rise time: When the unit is powered ON in RS485 mode the rise time defaults to load current walk-in. The rise time can be configured to be rapid turn-ON independent of the load profile. 0 0.1 An open circuit on this pin reverts the voltage level back to the original setting of 48V Software commanded margining overrides the hardware set point indefinitely or until the default setting is reinstated for example if input power and bias power have been removed from the module. January 7, 2013 Fault: This signal goes LO for any failure that requires Rectifier replacement. Some of these faults may be due to: Fan Speed Control: The fan speed can be instructed to turn faster than what is required by the power supply using either the RS485 or I2C protocols.
