ThermalRite Blast Chiller Easy Touch Screen Manual
5.5.
This is the list of all alarms event that may occur during operation, along with a
recommendation on how to solve them.
ALARM Name:
➢
DOOR -
The door is open for more than the allowed time during a cycle.
➢
MAINTENAINCE
–
This is a reminder to perform a regular service inspection and
preventive maintenance. Contact an authorized service company for service.
➢
CONDENSER HIGH TEMPERATURE -
It means that the
Condenser
temperature
exceeds
140°F/60°C
, as defined by the
(MCT)
parameter.
➢
EVPORATOR LOW TEMPERATURE -
It means that the
Evaporator
temperature is
too low when compared to the current
Set-point
temperature. There is a differential
parameter
(LBT)
that states the maximum gap that should exist between
Set-point
temperature and
Evaporator
temperature. This alarm it’s not a critical one, however
it could be avoided by resetting
(LBT)
parameter to
50°F/10°C
.
➢
DEFROSTING TIME
–
It means that the
Defrost
process was not terminated within
the maximum defrosting time. The
Defrost
normally ends by coil temperature
parameter
(DTE).
If this doesn’t happen within defrost parameter
(DTO)
minutes,
then the alarm triggers. The amount of ice on the evaporator coil, may require more
than one defrost. If the alarm occurs during the
Hold
cycle, there may be a problem
with the defrost hot gas valve. Using the
Blast Chiller
as a holding cabinet for a long
time may reach to this alarm too.
