CONTROL AND DISPLAY PANEL
 

Easy to navigate 128x64 graphical LCD display with keypad provides LED indicators for switch position, source availability, not in auto, and alert condition.
 

STANDARD FEATURES
 

  • Inphase monitor to transfer motor loads, without any intentional off time, to prevent inrush currents from exceeding normal starting levels.
  • Engine exerciser to automatically test backup generator each week—with or without load for 20 minutes.
  • Selective load disconnect control contacts (two provided) which operate with time delay prior to and/or after load transfer and re-transfer.
  • 60Hz or 50Hz selectable switch. Three – phase/single - phase selectable switch.

    VOLTAGE & FREQUENCY SENSING
     
  • Three phase under and over voltage settings on normal and  emergency sources.
  • Under and over frequency settings on normal and emergency sources.
  • True RMS Voltage Sensing with +/-1% accuracy Frequency Sensing Accuracy is +/- 0.1Hz
  • Voltage and Frequency parameters adjustable in 1% increments
  • Selecting settings : single or three phase voltage sensing on normal, and single phase sensing on emergency; 50 or 60 Hz
     

COMMUNICATIONS FEATURES
 

Requires accessory 72EE
 

  • Built in web server, with full display and control capabilities
  • E-mail capability for system events, including e-mail to SMS text messaging.
     

REMOTE CONTROL FEATURES
 

  • External Inputs for connecting:
  • Remote test switch.
  • Remote contact for test or for peak shaving applications. If emergency source fails, switch will automatically transfer back to normal source if acceptable.
  • Inhibit transfer to emergency
  • Remote time delay bypass switch emergency to normal

    TIME DELAYS
     
  • Engine start time delay – delays engine starting signal to override momentary normal source outages – adjustable to 0 to 6 seconds (Feature 1C)
  • Transfer to emergency time delay – adjustable 0 to 60 minutes (Feature 2B)
  • Emergency source stabilization time delay to ignore momentary transients during initial generator set loading – adjustable 0 to 4 seconds (Feature 1F)
  • Re-transfer to normal time delay – adjustable 0 to 10 hours (Feature 3A)
  • Unloaded running time delay for engine cool down – adjustable 0 to 60 minutes (Feature 2E)
  • Pre and post signal time delay for selective load disconnect with a programmable bypass on source failures – adjustable0 to 5 minutes (specify ASCO Optional accessory 31Z)
  • Adjustable time delay to override momentary normal source outages to delay all transfer switch and engine-starting signals.
