exceed
230Žo
C.
Manual
intervention
is
required
to
reset
control
in
the
event
of
a
failure.
To
Reset
Open

pan.
Withdraw
capillary
and
probe
from
pan.
f)
Replace
in
reverse
order.
Operation
of
the
high
temperature
limit
device
must
be
checked
at
regular
intervals
adopting
the
following
procedure:
a)
As
per
items
2(a)
and
(b)
above.
b)
Bridge
thermocouple
connection
on
PCB
with
a
short
piece
of
wire
(see
wiring
diagram).
c)
Fill
pan
with
oil
to
indicated
level
mark
and
install
a
means
of
measuring
the
oil
temperature.
Measuring
sensor
must
be
placed
at
geometric
pan
centre,
25mm
below
oil
surface.
d)
Switch
unit
on
and
observe
rising
oil
temperature.
If
unit
functions
properly,
high
temperature
limit
device
will
cut
the
power
supply
when
temperature
of
oil
is
between
220Žo
C
and
225Žo
C.
Should
device
fail
to
operate
at
a
maximum
temperature
of
230Žo
C,
shut
unit
OFF
immediately
by
pressing
OFF
switch
on
control
panel.
Undertake
investigations
to
detect
fault.
e)
Once
satisfied
that
high
temperature
limit
device
is
functioning
correctly,
remove
bridge
connection
from
PCB.
Replace
all
panels
and
push
re
‐
set
button
to
activate
control.
