‘EXTERNAL CONTROL’ port. (if there are 2 SBS-S units, please contact us to order the
special control wire)
4.13.1.2 Setting
a) Select the correct ‘Clamp range’ in SBS-4815CT Setup interface
b) set all 4 stop thresholds and other details in SBS-4815CT
parameters interface, and set the total discharge current to
‘TestCurr’ you need (for example: 200A in total).
c) set all stop thresholds in SBS-S unit(s), and set current to the max
value which SBS-S unit(s) can offer (for example: set 100A in
SBS-1110S).
d) Save all setting in SBS-S unit(s) and let LCD on the discharge screen.
4.13.1.3 Discharge
a) Start discharge at SBS-4815CT, and when the current goes up to the max value
which the SBS-4815CT can offer, it will send out control signal to SBS-S unit(s). SBS-S
unit(s) start discharge up to the setting value.
b) External clamp will add all discharge current from SBS-S unit(s) to SBS-4815CT.
And SBS-4815CT will offer the proper current to keep the total current you set.
(For example: 200A in total, if SBS-S offer 100A, SBS-4815CT will offer 100A, if SBS-S
offers 80A, SBS-4815CT will offer 120A)
c) If any stop threshold is reached in SBS-4815CT, all SBS-S unit(s) can accept control
signal to terminate the discharge at the same time.
