Arched Ceia detector - service repair.
The Italian company CEIA was founded in 1962. The company's products are used to organize security systems at airports, military facilities, government agencies, banks, stadiums, etc. In addition, CEIA manufactures systems for the food and pharmaceutical industry, the chemical and mining industries, as well as for the textile industry.
In this article I will describe some of the common defect in the Ceia classic and Ceia classic navy arched metal detectors.
Ceia classic navy is notable for its lower height, hermetic block electronics , the presence of signal processing programs, and the ability to create and save its own programs.
Defect - no sound.
Arched Ceia classic detector - no sound.
The sound in the metal detector is implemented using the MT-520 buzzer, which has high power, high impedance, and waterproof glass reinforced nylon case. Peak voltage buzer - 60V. For the required sound voltage applied step-up transformer ICE5-EBM.
Arched Ceia detectors - boozer and step-up transformer.
Arched Ceia detectors - sound amplifier.
If there is no sound, we check the described elements accordingly.
Defect - not see an arched antenna.
Arched Ceia detector do not see an arched antenna.
If Arched Ceia detector does not see the antenna, check the COM port driver on the ADM242 specialized chip and its harness.
If in Arched Ceia detector there is no output signal to the transmitting antenna, we check the indicated resistors by 0.2, by 1.5, by 6.8, by 20 Ohms, and the output transistors of the IRF740 transmitter.
We start troubleshooting by checking the voltages on the integral voltage regulators from Linear Technology.
LT1185 - 5V linear stabilizer.
LT1086 - 3.3V linear stabilizer.
LT1185 and LT1086 - these are high-quality linear integrated stabilizers at 5 and 3.3V, with a voltage drop of less than 1V and high accuracy of the output voltage.
