  • Page 7: What Is Ezt-430I

    EZT-430i. EZT-430i can store more than one year of data on its SD memory card. Data logging can be enabled manually or automatically during program operation. Data backup is provided with a USB memory stick for plug and play transfer of files to any PC running Microsoft Windows XP, Vista operating systems and via the FTP back-up utility.
  • Page 8 EZT-430i User’s Manual The EZT-430i controller includes the following features: • Single/Dual loop controller models (automatic program operation included). • Touch screen, “Smart Device” user interface (UI). • Video recorder mode for view only applications. • Email, SMS, FTP, VNC and Web functionality standard.

  • Page 9: Installation

    EZT-430i must be installed correctly for reliable operation. The EZT-430i controller is designed for installation within a suitable enclosure. Do not install EZT-430i outside of an enclosure. Care must be taken when locating components to ensure that AC power wiring, contactors, starters, relays and other sources of electrical interference are properly located to minimize their impact on the EZT-430i control system.

  • Page 10: Locating The Ezt-430I Touch Screen Interface

    Minimum and maximum relative humidity levels are limited between 10% and 90% (non- condensing) for the touch screen and 0 to 90% for the loop controllers. The EZT-430i touch screen interface is to be used indoors only. The unit should not be installed where fast temperature variations may occur as this can cause condensation of water vapor on the device.
  • Page 11 EZT-430i User’s Manual NOTE: EZT-430i will not operate properly without the SD card installed into the SD card slot on the back of the unit. The SD card has all software required, loaded onto the card for ‘Auto-Boot’ operation. The slot on the back of the interface is ‘keyed’...

  • Page 12: Ezt-430I Process Loop Controllers

    EZT-430i Process Loop Controllers One PID loop controller is required for each process control loop in the system. EZT-430i is compatible with both the P41, 1/4 DIN controller and the B41 board level controller. Refer to the CSZ controller manual for the model of loop control being used for dimensions, appropriate mounting and installation instructions.

  • Page 13: Wiring

    If EZT-430i is installed in an area with poor power quality or frequent power interruptions, it is recommended that a time delay-on relay be installed in the power supply wiring to all components of EZT-430i. This will prevent rapid on-off cycling of EZT-430i during brown-out or momentary power interruptions. Rapid power cycling to EZT-430i can cause damage to the electronics and/or loss of data.

  • Page 14: Installing The Power-On Delay Relay

    In order to properly sense the loss of power, due to the hold-up times associated with AC/DC power supplies, the time delay relay coil should be wired to the AC power source for the DC power supply of EZT-430i. This will insure that EZT-430i is turned off/on at the proper times and prevent malfunction that can be caused by rising or falling voltage at the power supply output during power interruption.

  • Page 15: Connecting To The Ezt-430I Interface

    EZT-430i User’s Manual 3.2 Connecting to the EZT-430i Interface Power wiring lengths should be kept to a minimum, and it is preferable to have the power wiring run using a minimum of 18/2 twisted shielded cable. This keeps the ‘hot’ and common wires paired to minimize the effects of external noise.

  • Page 16: Process Loop Controller Communications

    3.2.1 Process Loop Controller Communications The loop controllers communicate with the EZT-430i touch screen using the RS485 communications port. This allows one or two controllers to be connected using one 2-wire link. The controllers are wired in parallel with each one having their own communications address of 1 and 2 (corresponding to loops 1 and 2).

  • Page 17: User Serial Communications

    The EZT-430i touch screen provides an RS232C user communications port for connecting EZT-430i to a PC running software such as CSZ’s Envision. In order to connect EZT-430i to a PC, a cable must be made according to the diagram below.
