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.
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.

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
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.
