Dual-Path power transmission monitoring feature
41.
The 2401ST PSU has an optional mode designed to
work with systems that require dual-power
transmission paths. When enabled, the PSU compares
the outputs and reports a load imbalance of more than
10% as an OUTPUT FAULT (LED 4 x6 Flashes) and is
enabled by removing the header marked
OP1
≠
OP2
This mode meets the requirements of EN54-13 Section
5.3.3.1 S
FAULT
and Section 5.3.4.2 P
FAULT
warning
conditions, for loads above 200mA.
It is still necessary for the connected equipment to be
designed to accept two separate power inputs, such
that a short to ground of either power transmission
path, will not inhibit the equipment performance.
PSU Addressable Data link communication protocol
42.
The 2401ST PSU has an addressable RS485 communication port, that can be enabled to provide the
internal PSU data, and includes; Mains Voltage; Output1 Voltage/Current; Output2 Voltage/Current;
Battery Voltage; Charger Current; GEN Fault condition; EPS Fault condition; Diagnostics fault status
(condition 1-6), Battery temperature, Charger status, unit address
43.
