• The yellow LED luminosity
depends on:
– Load voltage.
– Control: ON or OFF.
– Load type.
• The status outputs can be
connected in series.
• NPN or PNP output is possible
with status.
• Mains voltage lower than
specifications (150 Vac). The
SSR works correctly, but an
alarm status can be given
without control.

• Output status is normally closed
without failure on the relay and
the load. The output LED is
normally ON.
• In case of failure on the load
(open) or on the SSR (short-
circuit condition):
- the status is open
- the output LED is switched OFF
Important: If you use a long
wiring cable between the SSR
and the load (>25 meters), the
diagnostic system might not be
able to detect an open load.
