1.
No power to the control panel
a.
Check to be certain unit is plugged
into 240vac outlet and that there is
power at the outlet.
b.
Be certain that breakers in panel box
are not tripped
i.
If the breakers are being tripped,
the system is likely being
shorted to ground. Look for any
blown fuses to indicate trouble
areas and consult the fuse layout
for more detail. Have the system
checked by a certified
electrician before operating.
c.
Check the 1amp fuse (F1). Make
sure there is 115vac to and through
the fuse. If not, replace with
appropriate fuse. DO NOT
REPLACE WITH OVERSIZED
FUSES.
d.
Check the rocker switch to see if it
is lit when switched on. This should
indicate that power is getting to the
switch. Check for 115vac power
between white and black wires at
the switch terminals for constant
power. Red and White should carry
115vac once the switch is flipped. If
there is not 115vac leaving the
switch through the red wire when
switched on, the switch may need
replacing.
e.
Make certain that the power
connections between the controller
and the controller have not become
loose. These are the black and white
wires at terminals 13 and 14 from
the control to the High Terminal
Block.
f.
The control itself could be
malfunctioning or internally
damaged. This is only rarely seen.
Call for assistance.
2.
Milk does not heat and the heater is not hot.
a.
Heat components: Control calls for
heat by signaling the SS Relay. The
signal passes through the thermostat
at the bottom of the tank and returns
to the SS Relay which is then
switched and activates the contactor.
When the contactor is pulled in it
permits current to the heating
elements which then heat the milk
or colostrum.
