The control cabinet schematic diagram is seen Fig. 2, major function and technical parameter:
1. supply voltage: AC220V+10%～15%, 50Hz, power consumption＜6W.
2. suitable environment: temperature-20～45 ℃, relative humidity≤85%.
3. temperature control: control setting range-35～50 is ℃ adjustable, 1.0 ℃ of resolution ratio.
4. return the temperature difference: 1～10 ℃ of setting range of control is adjustable, 1.0 ℃ of resolution ratio.
5. integrating cycle: (defrost is spaced apart the compressor accumulative total working time, and compressor does not move not-time) control setting range: 0.4～24H is adjustable, resolution ratio 0.1H.
Do not have the defrost function when transferring to OFF, be applicable to cooling grid and do not need the equipment of defrost.
6. import: CH
1(Ku Wen), CH
2(evaporimeter comb) produces temperature sensors of high precision for the U.S., precision 1%, and year drift＜1 ‰, standard line length 5m, maximum distance＜200m, elongated line partly do not have specific (special) requirements.
Compressor open-phase protection (with the thermal element duplicate protection).
The compressor protection input port.
Condenser, air-cooler electric motor protecting input port.
Compressor suction pipe pressure protect input port.
Open-phase protection just often for the open circuit, other each mouthfuls just often all with power supply phase line closure.
7. output: this controller is totally six tunnel outputs, condenser fan (or water pump), liquid supply electromagnetic valve, the output of reporting to the police, defrost output, compressor output, evaporator fan output.
Seal in the AC220V power supply in each delivery outlet, can be with the following load of 2A.
8. compressor protection: compressor start time and last downtime at interval＞3 minutes, the shortest running time＞3 minute after the start per hour guarantee startup-shutdown＜8 time, suction and discharge pressure protect, overload, open-phase protection.
9. when compressor accumulated running time near the integrating of having set during the cycle, computer detects, whether Ku Wen is lower limit, whether unit operation normal, whether evaporimeter has frost, satisfies as above condition, adds defrost automatically.Differ more as Ku Wen with setting numerical value, the time-delay refrigeration is invalid, and this moment, computer thought that evaporimeter ice is stifled, needed defrost by force.
Defrost process: computer detects evaporator temperature, and when defrost is finished, evaporator temperature raises (this temperature value can change according to different requirement of user), and the defrost function withdraws from, the compressor start refrigeration.
When evaporator temperature reduce to＜at that time during temperature, evaporator fan starts, and enters normal refrigeration.Controller is provided with manual defrost key, makes a forcible entry into defrost by manual defrost key, degenerates automatically, also can manually separate.
10. abnormality detection: when unit height pressure limit, line voltage transfinites, compressor, condenser, evaporimeter generation phase shortage, overload, and sensor fault, computer take protection to shut down and sound and light alarm automatically.
(11) self check security function: computer is to self continuous detection during work, and any interference is got rid of automatically, and the instruction of correcting a mistake automatically the phenomenon that crashes can not occur, the various data outage of internal memory long-term memory.
(12) show: 3 super bright red numerals show, display setting value during the display setting operation, working time shows storehouse temperature, press comb temperature key and show evaporator temperature, show the trouble location code during fault, indicator lamp shows each road loaded work piece state and setting content respectively, and charactron is switching on and shutting down time-delay state when red point flashes on the upper left side.
(13) controller: volume 145 (length) mm * 120 (wide) mm * 60 (height) mm, weight 0.85kg, attached two high-precision sensors (interchangeable).
(14) panel: controller panel is annotated for full Chinese and is shown, only needs design temperature, returns the temperature difference, and integrating cycle 3 parameters are that parameter is set when key places the S position, are operation automatically during the W position.
