Installation Safety Considerations Please follow all applicable local and national codes to ensure maximum safety of the equipment and personnel. The installation and operational environment must be maintained per the latest revision of these codes. You are responsible to determine the codes to be followed and to verify the compliance of equipment, installation, and operation with the latest revision of these codes.
Installation Considerations Our products have been designed and tested for operation in the most demanding industrial environments. Modern solid-state industrial controls are complex electronic equipment that operate at low levels of voltage and current, co-existing with components that operate at much higher levels of power. The difference in operating power characteristics between the high and low power control devices creates the possibility of unwanted signals being generated, thus causing interference.
(motors, starters, solenoids, etc.) should be housed separately or at the farthest point when enclosed within the cabinet. We recommend that the EZ TouchPLC have a minimum clear space of 2" on all sides for adequate ventilation as shown in the image on the right. Electrical Considerations This section is designed to provide you with a very basic understanding of electrical noise and how to keep it away from CPUs.
Shielding from RFI Shielded Cables Power cables, I/O cables or wiring, and communication cables should all be separate so that they do not couple the conducted RFI on any of these wires/ cables. Another path for RFI into the PLC is through its RS232 port. Hence, the cables to this port must be shielded properly.

Cabinet Wiring The wiring of the EZ TouchPLC to the “field outside the cabinet must be by design. The wiring cannot be random in order to get the various points of the cabinet and the “field electrically connected. Below are some general rules that apply in most situations: o Provide a separate power source to electronic controls and keep this power bus away from any I/O power.

Mounting Instructions (6 Inch Model) The 6-inch models must be mounted using DIN Clips. DIN Clips are metal brackets (P/N EZ-BRK-1, package of 2 brackets and 4 screws) that attach to the panel and secure the front panel to a mounting surface with 4 screws. Use the diagram and instructions below to mount the EZ Touch Micro unit using DIN Clips.
Page 14
Mounting Instructions (8 and 10 Inch Model) Before mounting your EZ TouchPLC unit, please verify you have the necessary items: · EZ TouchPLC unit · 4 DIN clip assemblies · a Phillips #1 screwdriver (or equivalent) When ready to proceed: Prepare the DIN clip assembly first by placing the nut on the screw.
Communication and Wiring 1. Powering the Unit Connect the power input wires into the PLC's power terminals. Supply 24VDC nominal (20-28VDC) power to the system. If the unit does not power up correctly, remove power from the system and check all the wiring. In addition, see the Indicator Light section for troubleshooting.
2. COM1 Port The EZ TouchPLC Micro has a built-in serial port (COM1 PORT) located on the 9- pin D-Sub connector. COM1 PORT is an RS-232 port which requires an appropriate RS-232C cable (P/N: EZ-PGMCBL) for programming the EZ TouchPLC Micro through a PC.
3. Ethernet Port (Optional) There is also an optional Ethernet port available on select models for the EZ TouchPLC Micro. This port enables users to add/update programming through an Ethernet connection. Note: The units will ship with a fixed IP Address (192.168.0.1)
RS485 Port The EZ TouchPLC model comes available with two serial communication ports including a RS485 port. This RS485 port allows user utilize Communication Instructions as outlined in the EZ Panel Enhanced Software Manual. To enable this port, you would use the Open Port command.

Using the Panel Quickstarting the Device This section outlines the steps needed to setup the EZ TouchPLC Micro and get it started. This is not intended to explain specific details needed to start your system. Rather, it provides a quick guide to give a broad picture of what is needed to power-up EZ TouchPLC system.
PLC Operation Sequence A good understanding of the TouchPLC's CPU operating sequence will help you achieve the proper control for your equipment or process. The flow chart on the left shows how the CPU controls all aspects of system operation. Power-up Initialization On power-up, the CPU initializes the internal electronic hardware.
Page 28
Subroutines The CPU executes subroutines when called for in the ladder program. These subroutines are useful in performing the same logic operation time and time again just upon one call so you do not have to repeat the rung logic over and over again. 28 / 47...
Editing IP Address This section applies only to the units purchased with Ethernet capabilities. Units with Ethernet capabilities will arrive with a factory-programmed IP Address that may need edited to be compatible with your LAN network. The COM1 Port, in combination with the editing software, can be utilized to update the IP Address information.
