2、Technical parameter
1）、Actual temperature, setting temperature, baking time and actions showed respectively on digitron and indicator light.
2）、Output control:( switch output)
Up temperature 0～5V DC adjusting voltage output;
Bottom temperature 0～5V DC adjusting voltage output;
Steam valve relay output one-channel;
Lighting relay output one-channel;
Alarm relay output one-channel.
3）、Input signal: (except thermocouple, the input signal disconnection is effective)
K-type thermocouple input duplex;
Door switch signal input one-channel.
4）、Working power:50～60Hz AC110V±10% or 50～60Hz AC220V±10%. 1、Cautions in installation
1）、External power supply have abnormal changes will lead to the breakdown of control system, for the safety work of the whole system, please make sure to set safety circuit outside of the control system.
2）、Operator must acquaint himself with the contents of manual before installation, wiring, operation and maintenance. And operator must know very well related mechanical and electronic common sense and all relevant safety cautions.
Notice: Improper operation may cause hazards, including personal injury or equipment accident.
3）、Please install on metal or other flame retardant matters and away from fuel.
4）、Should be safety grounding when use.
5）、Wiring operation must be done by professional electrician.
6）、After the disconnect power is confirmed, operation could be started.
2、System installation and commissioning
1）、Should install electricity box of controller in place with good ventilation, oil-proofing and dust proof. If the electric control box is closed, temperature of controller will be too high, affect the normal work and the exhaust fan should be installed; the preference temperature of electricity box is below 50℃ and relative humidity less than 85%RH.
2）、It is necessary to avoid controller being installed too close to AC accessories: contactor, transformer, and so on; the controller must be kept away from strong electromagnetic field environment, for avoiding unnecessary interference and affecting the normal work.
3）、Please have regular maintenance to ensure controller works without accident.
