Battery; Fault Relay Operation - Honeywell HLS PS Série Manuel D'utilisation

HW_MN-DT-1305_C

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), 17Amp/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.
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
