For your own safety and to avoid damaging the instrument we suggest you follow the procedures hereby prescribed and read carefully all the notes preceded by the symbol . CAUTION Should you fail to keep to the prescribed instructions you could damage the instrument and/or its components or endanger your safety.
XL423 - XL424 1.2 DURING USE Carefully read the below recommendations and instructions: CAUTION No compliance with warnings and/or instructions may cause damage to the tester or its components or injure the operator During a measurement never touch any unused terminal. 1.3 AFTER USE If you expect not to use the instrument for a long period of time remove the batteries and strictly follow the indications at § 9.2. 1.
XL423 - XL424 2 GENERAL DESCRIPTION 2.1 INTRODUCTION The instrument was designed to grant the user the utmost safety conditions thanks to a new concept assuring double insulation and overvoltage CAT III 600V~ between inputs and to ground. 2.2 FUNCTIONS This manual is referred to two models: XL423 and XL423. Where not expressly indicated the characteristics are common for both models. XL423 can recording a single voltage in single-phase or three-phase plant.
XL423 - XL424 3 PREPARATION FOR USE 3.1 PRELIMINARY CHECKS This instrument has been checked mechanically and electrically before shipment. All precautions have been taken to assure that the instrument reaches you under perfect conditions. However, it is advisable to carry out a rapid check in order to detect any possible damage, which might have occurred during transport. Check the accessories contained in the packaging to make sure they are the same as reported in § 11. 3.

START/STOP key Fig. 1: Instrument description 4.2 KEYBOARD LED “STATUS” blinks every time the START/STOP key is pressed. 5 INITIAL SETTINGS 5.1 DATE, TIME AND MEASURING INTERVAL It’s possible to set measuring interval as well as date and time by using the management software.
XL423 - XL424 6 OPERATIVE INSTRUCTIONS 6.1 USING THE INSTRUMENT IN A SINGLE PHASE SYSTEM CAUTION The Instrument can be used on installation with overvoltage CAT III 600V~ between the inputs and to ground. Do not attempt to take any voltage measurement exceeding the limits indicated in this manual. Exceeding the limits could cause electrical shock or damage to the instrument. Fig. 2: Instrument’s connection in single phase system CAUTION De-energize the plant under test before connecting the instrument.
XL423 - XL424 6. During a Recording: A 3 seconds blinking of STATUS LED means that the recording is active and the instrument is storing the data. A 3 seconds blinking of ALARM LED means that the batteries are low. During a recording any RS232 communication is possible. During Recording operations RS-232 serial communications to PC are not possible. 7. Stop a Recording: To stop a Recording press START/STOP key and keep it pressed for 3 seconds.
XL423 - XL424 6.2 USING THE INSTRUMENT IN A THREE PHASE 4-WIRES SYSTEM CAUTION The Instrument can be used on installations with overvoltage CAT III 600V~ between the inputs and to ground. Do not attempt to take any voltage measurements exceeding the limits indicated in this manual. Exceeding the limits could cause electrical shock or damage to the instrument. Fig. 3: Instrument’s connection in three phase 4-wires system CAUTION De-energize the plant under test before connecting the instrument.
XL423 - XL424 6. During a Recording: A 3 seconds blinking of STATUS LED means that the recording is active and the instrument is storing data. A 3 seconds blinking of ALARM LED means that the batteries are low. During a recording any RS232 communication is possible. During Recording operations RS-232 serial communications to PC are not possible. 7. Stop a Recording: To stop a Recording press START/STOP key and keep it pressed for 3 seconds.
XL423 - XL424 6.3 USING THE INSTRUMENT IN A THREE PHASE 3-WIRES SYSTEM CAUTION The Instrument can be used on installation with overvoltage CAT III 600V~ between the inputs and to ground. Do not attempt to take any voltage measurement exceeding the limits indicated in this manual. Exceeding the limits could cause electrical shock or damage to the instrument. Fig. 4: Instrument’s connection in three phase 3-wires plant CAUTION De-energize the plant under test before connecting the instrument.
XL423 - XL424 5. How to start a Recording: If no recording was performed or if the recording data had been already downloaded to a PC, press the START/STOP key for 3 seconds. The STATUS LED will be lighting for the same time, than will become stable for 1 second and the instrument will start recording. If the recording data had not been already downloaded to a PC and the operator wants to overwrite these data, press the START/STOP key for 6 seconds.
XL423 - XL424 7 LED MESSAGE DESCRIPTION For the STATUS and ALARM LED messages please refer to the following table: LED START/STOP Key Light STATUS Kept pressed 3 seconds at least On for 1 second STATUS Kept pressed 6 seconds at least 6 times blinking after 1 second on STATUS Not pressed STATUS Not pressed STATUS Pressed ALARM Not relevant 2 times blinking every 3 seconds 1 time blinking every 3 seconds 3 times blinking 1 time blinking every 3 seconds Description Recording process correctl
