2.2 Battery
DIP SW2 allows selecting the maximum current of battery load,
depending on the batteries inside the power supply unit box.
With DIP SW2 in ON position (up), 7Amp/h batteries can be charged
at 300mA. When DIP SW2 is in OFF position (down), 20Amp/h
batteries can be charged at 600mA.
In this example, DIP SW2 is in OFF position
(down) and the load current will be limited to
600mA.
DIP SW3 . This DIP switch is in ON position (up).
For future use.
DIP SW4 . For future use.
2.3 Fault relay
The Power Supply has a fault relay to report any anomaly to a remote
control unit.
Any fault has a delay of 30 seconds from the fault signal to fault relay
confirmation, except when there is a mains AC loss, which will be
indicated after an 8-minute delay to avoid faults from intermittent
power cuts.
In stand-by, the fault relay is energized indicating its normal operation.
In case of any fault, the relay deactivates after the confirmation time.
Fault relay operation
FAULT switch with three terminals
Terminal 1 (left) C common
Terminal 2 (centre) NC or Normally Closed
Terminal 3 (right) NO or Normally Open
Fault relay operates as follows:
No supervision (without power) or in fault condition
Between C and NC —> continuity
Between C and NO —> open circuit
Operating with supervision without faults, i.e. in NORMAL STATE
Between C and NC —> open circuit
Between C and NO —> continuity
