IS200ESELH1A Mark VIe Control System

Functional Overview
The IS200ESELH1A is a 24-channel discrete (digital) input module in the GE Mark VIe control system. Its primary function is to collect discrete signals (contact open/close signals) generated by field devices such as sensors,
 switches, and relays, convert them into digital signals that can be recognized and processed by the PLC or control system CPU,
and transmit the processed data to the GE Speedtronic turbine control system or other control equipment, enabling automated control and monitoring.

Certifications and Safety

This module is UL certified and can be used in both hazardous and non-hazardous locations. The UL certification covers various classes and divisions, and relevant UL mark documents are available for reference.

5) If you find that some areas of the touch screen cannot be touched after using it for a long period of time (3-4 years), the touch screen may be broken. Please replace the touch screen.

If it is a capacitive touch screen, you can perform the following maintenance:

3. Touch screen response time is very long

[Troubleshooting]

A touch screen takes a long time to respond after touching the monitor screen with your finger.

[Fault analysis and processing]

This may be caused by moving water droplets stuck to the touch screen, just wipe it with a dry soft cloth. It is also possible that the host is too low-grade, such as the clock frequency is too low. If this is the case, it is best to replace the host.

4. The touch screen is partially unresponsive

[Troubleshooting]

A touch screen, after touching the monitor screen with a finger, there is no response in some places.

[Fault analysis and processing]

It is possible that the reflective stripes on the touch screen are partially covered. You can wipe them clean with a dry soft cloth. It is also possible that the reflective stripes on the touch screen were partially scratched off by a hard object and cannot be repaired.

5. The touch screen works normally but the computer cannot be operated.

[Troubleshooting]

A touch screen itself is tested and everything is normal, but after being connected to the host computer, the computer cannot operate.

[Fault analysis and processing]

This may be because the touch screen control card receives the operation signal before the host starts loading the touch screen driver. You only need to cut off the power again and then restart the computer. It is also possible that the touch screen driver version is too low and the latest driver needs to be installed.

6. The touch screen does not respond when started for the first time after installing the driver.

[Troubleshooting]

I have a touch screen. After installing the driver, the touch screen becomes unresponsive when I start it for the first time.

[Fault analysis and processing]

First, confirm whether the touch screen circuit connections are correct. If not, shut down the machine and connect all the circuits correctly. Then check if there are any devices in the host that conflict with the serial port resources, check each hardware device and adjust them. For example, the default IRQ of some network cards after installation is 3, which conflicts with the IRQ of COM2. At this time, the IRQ of the network card should be changed to idle and unused. IRQ.

7. No response to touch after using for a period of time

[Troubleshooting]

A touch screen becomes unresponsive after being used normally for a period of time after being turned on.
