27. ximum I This is the maximum current in amps output of the driver connected to the controller This depends on the driver model and wattage The current setting on the main page is based on this maximum value You will also see a warning screen when the controller is first powered up verifying this setting Line 4 Max Rate The maximum repetition rate in Hz when in continuous or burst mode This should be set to whatever the driver maximum pulsed repetition rate is The active rate cannot be adjusted higher than this value System Setup Page 2 Setup 2 Temp Fault Intlk Cntrl Pulse Enabl The system setup page 2 allows you to setup interlock default states and whether or not the LDDC should allow pulsing of the driver Please refer to the diode driver data sheet for the specific interlock options and whether or not it supports pulsed modes These values can be stored for later recall in the save recall page Line 1 Indication of System Setup 2 page No function 59lPage Line 2 Temp Fault bvpass This will allow vou to bvpass the over temperature fault input on pin 11 Options are either En enable or Byp Bypass Not all drivers have the temperature fault indication so this allows that input to be ignored Line 3 Intlk Cntrl Interlock control bypass This will allow you to bypass the manual operation of the interlock control on the Status Information Page When set to Byp bypass the interlock will automatically be enab
