Foxboro P0971SU Control Board Card

Description

Regular inspections are necessary to ensure that the Xinjie PLC operates continuously in its optimal state Because the main components of PLC are semiconductor devices and operate for a long time, the working environment will have an impact on it, sometimes causing damage The inspection contents are as follows:

(1) Power supply: Whether the power supply voltage is the rated voltage; Whether the power supply frequency is the rated frequency;

(2) Operating environment: Whether the temperature, humidity, vibration, dust, etc. meet the requirements

(3) Installation: Check whether the grounding resistance meets the requirements. Regularly (usually once to twice a year) shake and test whether the installation is secure.

Regularly (usually once to twice a year) tighten the wires to ensure good contact. The wiring screws must be tightened and there should be no abnormalities in the appearance Lithium battery and relay replacement. The lithium battery and relay output contacts in the PLC are lossy devices that need to be replaced according to the situation after a long period of use (1) The function of a lithium battery is to protect the contents of programs and counters stored in RAM (random access memory) At 25 ℃, the lifespan of a lithium battery is 5 years The higher the temperature, the shorter its lifespan When the battery fails, the CPU’s ALARM indicator light flashes, and within a week thereafter, the lithium battery must be replaced Replacement steps:<1>Disconnect the power supply of the PLC.

If the power supply of the PLC is initially disconnected, it must be connected for at least 10 seconds before disconnecting< 2> Open the CPU cover plate (depending on the products of different manufacturers, the opening method may vary, and should refer to their instructions to avoid damaging the equipment)< 3> Within 5 minutes (as soon as possible), remove the old battery from the bracket and install the new battery< 4> Reinstall the CPU cover< 5> Clear ALARM using a programmer (2) Relay<1>Disconnect the power supply of the PLC<2>Open the cover<3>Use the special tool provided by the manufacturer to remove the damaged relay and install a new one< 4> Install the cover plate.
