Troubleshooting

If  you  encounter  difficulties  while  using  the  

EZTouchPLC

 device,  please  consult  the list

 

below   which   outlines   common   troubleshooting   issues   and   their   solutions.    Additional

 

assistance  is also available  within the 

EZ

Touch I/O

 Software Help

. Alternatively, you

Issue

: Panel won't power up

Solution

Apply power and observe the LED in the back of the panel

a) LED does not turn on: No power to the unit or power supply failed, check the

power supply.

b) LED turns RED and stays RED: Unit has failed, Please return the panel for repair.

c) LED flashes RED and turns GREEN: Unit is OK, Display might have gone bad. Return

panel for repair.

Issue

: Can't program the unit using USB Programming cable

Solution

Disconnect and then reconnect the programming cable

Please unplug the USB programming cable from the computer and close the

programming software. 

Plug the USB cable back in, wait for 10 – 15 seconds and launch the Programming

software.

Our programming software reads the com ports directly from the device manager of

the computer and it has auto detect feature.

Issue

: USB Flash drive is not recognized

Solution

Using a different USB Flash drive, ensure the USB function is enabled

Using a low memory capacity USB Flash drive, preferably less than 2 GB, press and

hold the upper left corner of the Touch screen for about 6 seconds to reach the 

Setup

menu on the panel.  Click on 

English

. Check the 2 pre-programmed buttons to ensure

USB is enabled and “Log to SD (Now USB)” buton is enabled.  Restart / power cycle

your panel.

Issue

: Touch cells not responding

Solution

Initiate a TouchPad Test

Press and hold the upper left corner of the Touch screen for about 6 seconds to reach

the 

Setup

 menu on the panel.  Click on 

English

.  Click on the 

Touchpad Test

 button and

press all Touch cells to see if it responds to Touch. If all buttons respond, then there is

no problem with the Touch screen.  If some or all of the touch cells don't respond to

touch, then the unit needs to come back to the factory for repair.

Issue

: Ethernet not responding

Solution

Set the IP Address

1.

Please set the IP address for the panel using our programming software and going

to 

Setup

 

>

 

Ethernet Setup

.

a.

Please match the first 3 octets of the IP address to your network and also

enter subnet mask.

b.

If your network has a gateway, then enter the gateway address.

2.

Please use a straight Ethernet cable and connect it through a hub.
