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.
It also includes test and time delay bypass soft keys.
Voltage & Frequency Sensing
3 — Phase under and over voltage settings on normal and
single phase sensing on emergency source.
Under and over frequency settings on normal and emergency.
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
Load current sensing card (Optional)
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 cooldown
– adjustable 0 to 60 minutes (Feature 2E)
Pre and post signal time delay for selective load disconnect
with a programmable bypass on source failures – adjustable
0 to 5 minutes (specify ASCO Optional accessory 31Z)
Optional fully programmable engine exerciser with seven
independent routines to exercise the engine generator, with or
without loads, on a daily, weekly, bi weekly or monthly basis
(Specify ASCO optional accessory feature bundle 11BE)
Delayed transition load disconnect time delay – adjustable
0 to 5 minutes.
Standard Selectable 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 20 minutes not adjustable.
Commit to transfer.
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
