8.3 STATIC RELAY
The static relay (B) is placed on the rear
side of the machine above the contactor, so
it possible to access it by removing the rear
panel, as described in chapter 3.
It controls the heating element of the steam
boiler. It is activated when the pressure
transducer detects a pressure lower than
that set.
The voltage availability is enabled by the
contactor. The switch ON/OFF command is
piloted by the control unit.
The right connections, LOAD, are the incom-
ing phase (1) and the outgoing phase (2).
The left ones, INPUT (3 and 4), are the com-
mands from to the control unit.
The operation is checked by means of LED
that light up in the heating phase of the
machine.
To test, simply let out a lot of steam from
the steam nozzle until the heating element
starts again.
Optimum operation will be when impulses
are spaced at varying intervals.
It is possible to verify LED on the control unit
too.
The static relay’s LED is labelled with SH, as
explained in paragraph 8.1.1.
PROBLEMS
The static relay can be damaged in ON or
OFF status, thereby giving high or low pres-
sure in the steam boiler.
