5.2 TWO ACCUMULATOR PRIORITY SYSTEM
1# Acc Charging
：
Iacc1 = Igen;
1# Acc on-load
：
Iacc1 = -Iload;
2# Acc Charging
：
Iacc2 = Igen;
2# Acc on-load
：
Iacc2 = -Iload;
1. Accumulator Switching Mode: Gap
1# Accumulator take load (K4 is closed)
；
When the 1# accumulator voltage has fallen below
the Charge Start Volt, K4 open relay will active, after 10s delay, 2# Accumulator take load (K5
is closed). During the above transfer process, the load is disconnect; The genset will be
started according to the preset sequence to charge the 1# Accumulator (K1 is closed).
Same procedures as above when 2# Accumulator transfer to 1# Accumulator.
2. Two Accumulator Switching Mode: Continuous
1# Accumulator take load (K4 is closed)
；
When the 1# accumulator voltage has fallen below
the Charge Volt, 2# accumulator voltage will be recorded and the genset voltage detection
begins; The genset will be started according to the preset sequence; When the genset
voltage rise to 1# accumulator voltage, K2 close relay will active and genset takes load. After
1s delay, K4 open relay will active. Adjust the genset voltage to reach to 2# accumulator
voltage, then 2# accumulator takes load (K5 is closed), K2 open relay active. After 1s delay,
K1 close relay active to charge the 1#
accumulator
．
Same procedures as above when 2# Accumulator transfer to 1# Accumulator.
NOTE
：
All above switch actions can be implemented when the controller is in Auto mode.
MANUAL TRANSFER PROCEDURES:
Accumulator Priority: K2 and K3 are always close. Press
button
，
if generator have taken
load (K1 Close)
，
will output unload signal (K1 Open)
；
if taken no load (K1 Open)
，
generator
will output load signal (K1 Close)
；
Generator Priority: K1 and K3 are always close. Press
button
，
if Accumulator have taken
