o Auto Test Timer is Automatically Bypassed on GeneratorExtended Timer
Ranges
o Warmup Timer 0 – 3000 seconds (was 30 minutes)
o Cooldown Timer 0.0 – 50.0 minutes (was 30 minutes)
o Neutral Delay Timer 0 – 120 seconds (was 60 seconds)
o Utility Return Timer 0 – 50.0 minutes (was 30 minutes)
o Pre/Post Transfer Delay 0 – 300 seconds (was 120 seconds)
7, 14, 21, 28 Day Programmable Exercise Timer
o Single Event Programmed Either Weekly, Every Second Week, Every Third
Week or Once a Month
o Allows Exercising On or Off Load (Programmable)
o All Settings Stored in Non-Volatile Memory
Programmable Commit to Transfer Logic
o Transfer Logic can be Programmed to either Logic Scenario:Commit to
Transfer to Generator Source only after Transfer to Generator Signal has
been Initiated (Existing Logic)
Or
b) Commit to Transfer to Generator Source only after Engine Start Delay
Timer Has Expired (New Logic). Can be used to prevent multiple Engine
Starts. Auto resetting if the generator fails to start in 5 minutes.
Neutral Delay Bypass
o Neutral Delay Logic can be Programmed to either Logic Scenario:
a) When Disabled includes the programmed Neutral Delay Time once neutral
positioning has been determined (Existing Logic).
Or
b) When Enabled only use as much of the programmed Neutral Delay Time
as required in the neutral position until the load bus voltage drops below 20% of
the nominal system voltage then completes the transfer to the alternate source
(New logic). Can be used to reduce the total transfer time while still providing
BEMF protection to the connected loads and/or power source. Also reduces
retransfer times on loss of alternate source by reducing or cancelling the
neutral delay time in a safe manner.
Transfer Fail Logic & Alarming
o More Descriptive Alarm Messaging: Utility Fail to Transfer, Generator Fail to
Transfer, Utility Power Switching Failed, Generator Power Switching Device
