The Units fields are used to enter the engineering units for the loop with up to four characters maximum. This value is shown on the single and dual view loop screens in the EZT-430i runtime application. When the loop input type selection is set for temperature, the field will be fixed at either “C” or “F” based on the units selection for the loop under loop setup. -
Page 10: Loop Address Utility
Loop Address Utility can be used. It is accessed from the Setup menu. In order to use the utility, only one loop control board can be connected to EZT-430i at a time. Since the default address of all control boards are 1, if more than one was connected, they would both respond to the same command which would cause them both to be set to a different address. -
Page 11: User Communications
3.3 User Communications The Modbus slave interface of EZT-430i can be set to operate in one of two modes. The default setting is to provide the standard user interface for use with CSZ’s Envision software. This selection assigns values to the Modbus slave register table in the proper positions to allow communications between EnVision and EZT-430i. -
Page 12: Loop Configuration
The loop control board is ordered with either a standard input for thermocouples and RTD’s, a voltage input or a milliamp input. The selected input type must be set to match the type of input supplied on the loop control board or the unit will not operate correctly. CSZ EZT-430i Configuring... -

Loop Setup screen. IMPORTANT: If EZT-430i is set for dual loop operation, both loop control boards must be set to the same function and both inputs must be wired to the same control switch if automatic ramp/soak programs are to be used. -
Page 15: Low/High Setpoint Limits
Deactivating the input will then cause the program to go into hold. The input must then be reactivated in order for the program to resume operation. NOTE: EZT-430i does not support the P41/B42 event input functions of “Off Mode” and “PID2 Select”. These selections are not available through the EZT-430i configuration. 3.4.7... -
Page 16: Output 1 Failure Transfer
If the output function is set for on-off control, the failure transfer can be set to have the output turn on (1) or turn off (0) when a sensor break occurs. CSZ EZT-430i Configuring... -
Page 17: Output 1 On-Off Control Hysteresis
The output function must be set to match the type of output ordered on the loop control board. Relay, triac and SSR output types are used for proportioning control, alarm or event outputs. The isolated Vdc and mA output types are used for linear control. Configuring CSZ EZT-430i... -
Page 18: Output 2 Failure Transfer
The Event output function allows the output to be turned on and off via an automatic program or manually through the EZT-430i interface to act as a “soft” switch to turn system components on and off. The DC power supply output function must be selected when the output type ordered for the loop control board output 2 is a transmitter power supply. -
Page 19: Output 3 Function
The Event output function allows the output to be turned on and off via an automatic program or manually through the EZT-430i interface to act as a “soft” switch to turn system components on and off. The DC power supply output function must be selected when the output type ordered for the loop control board output 3 is a transmitter power supply. -
Page 20: Output 4 Failure Transfer
The Event output function allows the output to be turned on and off via an automatic program or manually through the EZT-430i interface to act as a “soft” switch to turn system components on and off. The Retransmit process value and Retransmit setpoint value functions allow the loop control board output to retransmit the current input value or set point to remote devices such as a chart recorder. -
Page 21: Alarm (1-3) Function
The alarm will turn off when another program is started, when power is cycled to the loop control board or when the “Reset” button is pressed on the Alarm screen of the runtime application. Note that this “alarm” is not indicated on the EZT-430i interface. Configuring CSZ EZT-430i A.13... -
Page 22: Alarm (1-3) Mode
(static) mode of operation. The alarm will turn off when the loop control is running an automatic program. Note that this “alarm” is not indicated on the EZT-430i interface. The Holdback mode alarm is not associated with the process value or set point. The alarm is turned on when the running program is in holdback. -
Page 23: Alarm (1-3) Indication
3.4.24 Alarm (1-3) Indication The Alarm 1, 2 and 3 Indication settings are used to select whether the alarm will be shown in the EZT-430i runtime application or be hidden from the user. This allows the OEM to configure an alarm to perform a specific control function while preventing the user from adjusting the set point or seeing the activation state of the alarm. -
Page 24: Setpoint At Start Of Automatic Program
Loop Setup screen. NOTE: If EZT-430i is set for dual loop operation, it is recommended that both loop control boards be set to the same selection so that both loop controls start an automatic ramp/soak program in the same manner to avoid operator confusion. -
Page 25: Power Fail Recovery
“Done” button to set the power recovery mode for the loop control board and return to the main Loop Setup screen. IMPORTANT: If EZT-430i is set for dual loop operation, both loop control boards must be set to the same recovery setting. If the recovery mode for both loop control boards is not identical, program operation of one loop may continue while the other is terminated which will cause a program run error alarm to occur as well as result in incorrect operation of the program. -
Page 26: Enabling Holdback
EZT-430i configuration. 3.4.29.1 Enabling Holdback For single loop systems, holdback is enabled under program entry of the EZT-430i runtime application. The user is then able to select the desired hold type for each program step. For dual loop systems, holdback operation is conditional based on the configuration of the loop controls. - Page 27 By using the external relay, when the loop exits its holdback condition, its hold input will be triggered if the other loop is still in holdback, thus allowing it to enter the hold condition and continue waiting for the other loop to have its holdback condition satisfied.
