Page 4: Introduction
Since it is impossible to foresee all of the installations and environments in which the instrument may be applied, adequate technical preparation and complete knowledge of the instrument’s potentials are necessary. GEFRAN declines all liability if rules for correct installation, configuration, and/or programming are disregarded, as well as all liability for systems upline and/or downline of the instrument. -
Page 5: Structure Of This Manual
This manual was originally written in ITALIAN. Therefore, in case of inconsistencies or doubts, request the original manual or explanations from GEFRAN. The instructions in this manual do not replace the safety instructions and the technical data for installation, configuration and programming applied directly to the product or the rules of common sense and safety regulations in effect in the country of installation. -

- serial speed = 19200 bit/s - serial parity = none You can install a maximum of 99 IR-12/IR-24 modules in a serial network, with node address selectable from “01” to “99”. Settings Baud Select baud rate Baud rate table... -
Page 7: Inputs
INPUTS LINE VOLTAGE VALUE The RMS voltage values of each phase are shown in parameters Volt.Lp (with p = phase from 1 to 3). A voltage presence check is active for each phase; the check switches off the module if the voltage value is incorrect The S.General parameter contains information on line voltage status, including network frequency Reading status Volt.L1... -
Page 8: Digital Inputs
DIGITAL INPUTS Four digital inputs are always present. Each input can perform different functions based on the setting of the following parameters: Settings In.1 Table of digital input functions Digital input 1 function No function (input disabled) In.2 Digital input 2 function General alarm reset Enable/Disable loads of L1 phase In.3... -
Page 9: Alarms
ALARMS ALARM: thermal protection Each IR-12/IR-24 module has two temperature sensors for the internal heat sinks. The temperature values are show in variables Temp.1 and Temp.2 The overtemperature alarm shown in S.Alarm trips when at least one of the temperatures exceeds a set limit. -
Page 10: Alarms Fuse_Open, Ssr_Short
ALARMS FUSE_OPEN, SSR_SHORT and LOAD_OPEN Diagnostics is active to check correct functioning of the process: - FUSE_OPEN alarm: trips at opening of internal fuse - LOAD_OPEN alarm: trips when load is interrupted or disconnected - SSR_SHORT alarm: trips when the solid status relay is in short circuit NOTE1 : In PA_mode, the diagnostic Alarms Load-Open and Fuse_open are detected for SCR power firing higher than 40%. -
Page 11: Outputs
OUTPUTS ENABLING SSR OUTPUT CHANNELS The 24 output channels can be enabled by means of parameters En.Lp (with p = phase from 1 to 3). Enabling of the channels is saved in eeprom to maintain the last saved status at the next power-up. This saving can be disabled by means of the Option parameter. -
Page 12: Controls
CONTROLS In manual power control mode you can drive the outputs with a settable power percentage defined by: M.P.Lp.o (with p = phase from 1 to 3, o = output from 1 to 8). You can disable the saving of these parameters in EEPROM by means of the Option parameter (for example, in case of repeated changes by a PLC). - Page 13 Reading status Percentage of modulation of Power setpoint % of output 1 Out.P.L1.1 Pw.L1.1 output 1 phase L1 phase L1 Power setpoint % of output 2 Percentage of modulation of Pw.L1.2 Out.P.L1.2 phase L1 output 2 phase L1 Power setpoint % of output 3 Pw.L1.3 Percentage of modulation of Out.P.L1.3...

Page 14: Compensation Of Line Voltage
COMPENSATION OF LINE VOLTAGE This function lets you correct supplied power based on reference line voltage Volt.Nom.Lp (with p = phase from 1 to 3). The function can be activated / deactivated with the Option parameter. Correct compensation status is shown in the status of each S.Out.Lp.o (with p = phase from 1 to 3, o = output from 1 to 8). Settings Volt.Nom.L1 230.0... -
