10. Specific Control, Work Principle and Parameters
DW-86L628 has the temperature control system with a LED computer panel for controlling
the switch-on/off state of the compressor.
10.1
Temperature control system with a LED computer panel for controlling the
switch-on/off state of the compressor
1) In order to regulate the set value, firstly u
nlock the machine. First, press “
△
” or “
▽
”. When the
temperature set value flickers, press “
△
” or “
▽
”, input the figure “06”. Then, press the “Function
Selection” key for 5s. When the “Lock” indicator turns off, the machine is unlocked and you can set the
following values. Press the “Function Selection” key to set the temperature in the freezer, the high
temperature alarm and the low temperature alarm circularly and also the relevant indicators turn on.
2) When you
“set the temperature”, the temperature set value flickers in the temperature setting display
area. At that time, press “
△
” or “
▽
” to change the temperature set value. After that, the machine will be
locked automatically and the temperature display stops flickering if no key is operated in 10s, which
means that the value has been input into the computer. Otherwise, the setting is invalid. The
temperature setting scope is: -10 ~-86
℃
.
3) When the
“high temperature alarm” is set, the temperature set value flickers in the temperature setting
display area. At that time, you can press the shift or adjustment key to adjust the alarm set value. After
that, the machine will be locked automatically and the temperature display will stop flickering if no key is
operated in 10s, which means that the value has been input into the computer. Otherwise, the setting is
invalid. The temperature set value for high temperature alarm shall neither be higher than the maximum
temperature limit nor lower than the set temperature of +5
℃
.
4)
When the “low temperature alarm” is set, the temperature set value flickers in the temperature setting
display area. At that time, you can press
“△”
and
“▽”
to adjust the alarm set value. After that, the
machine will be locked automatically and the temperature display will stop flickering if no key is operated
in 10s, which means that the value has been input into the computer. Otherwise, the setting is invalid.
The temperature set value for low temperature alarm shall neither be lower than the minimum limit
temperature nor higher than the set temperature of -5
℃
. Otherwise, the value cannot be set.
10.2 Display and Alarm
After the freezer is switched on, it enters the starting mode, all parameters on the display panel will
remain the same with data before it is switched off last time, and the actual temperature, set temperature
and current voltage are displayed on the display panel.
Working condition indicators on the display panel:
If the indicator of
“Locking” turns on, it means all settings are locked to avoid maloperation.
If the indicator of
“Network” turns on, it means the network system is working.
If the indicator of “Run” turns on, it means the low temperature compressor is working.
If the indicator of “Voltage Stabilization” turns on, it means the voltage supercharger starts increasing or
decreasing the voltage.
If the indicator of
“Standby System” turns on, it means the standby refrigerating system is working;
Alarm state indications:
A.
“High temperature indicator: if the indicator turns on, the alarm will be displayed because the
