I. VERSION MARKING
1.1. Description
The controller is available in two versions: G-913-P00 (without built-in battery) and G-913-P01 (with
built-in battery):
The G-913-P00 recorder can only operate on mains supply
The G-913-P01 recorder can operate on a lithium-polymer battery that maintains data recording
after a power failure.
Operation under battery supply:
the G-913 recorder powered only by a battery, works for at least 24 hours from the moment
of power failure.
when the battery is completely discharged, an appropriate log is saved in the device.
when the mains supply is restored, the battery is automatically recharged.
1.2. How to order
When ordering a product, please:
specify the version P00(without battery) or P01(with battery)
select the supported sensor type: NTC 2.2kΩ or PT1000
select the default language: PL, EN, DE, FR (later configuration is possible, see page 9)
specify the required registration period
II. GENERAL CHARACTERISTICS
The G-913 digital temperature recorder was made in microprocessor technology with the use of an
automatic surface mount. The device is designed to record data from two temperature sensors
directly connected to it. The recorder is designed for stand-alone operation. The operating mode
depends on the settings made by the manufacturer.
The G-913 recorder is equipped with:
built-in memory for recording the measured temperatures
USB interface for reading stored temperature values
li-po battery depending on the version

ALWAYS DISCONNECT THE RECORDER FROM POWER DURING
THUNDERSTORMS
PENDRIVE CONNECTED TO THE RECORDER MUST BE
FORMATTED TO THE FAT32 FILE SYSTEM!
USING A PENDRIVE FORMATTED TO ANOTHER FILE SYSTEM IS
UNSUPPORTED AND MAY CAUSE INCORRECT OPERATION OF
THE DRIVER
The recorder does not require any special maintenance. The keyboard was made from a special
type of foil resistant to high temperature and most chemicals. It is not permitted to clean it with
sharp objects. It is sufficient to clean the front plate with a wet cloth from time to time.

III. CONNECTING AND POWERING THE RECORDER
The room where the Recorder is installed should be equipped with a 230V/50Hz electrical
system, in accordance with applicable regulations. The device does not require an external power
supply and can be connected directly to the mains. Connect the power cable conductors
according to the installation diagram shown in Fig. 1.
THE RECORDER IS CONNECTED TO 230V/50HZ POWER.
DISCONNECT THE POWER AT THE FUSE BEFORE ATTEMPTING
TO MAKE ANY REPAIRS
In order to enable the recorder to work in the event of a power failure or damage of the power
cord, G-913 was equipped with a built-in lithium-polymer battery. The recorder can work on
batteries for 1.5 - 2 weeks. The battery is automatically charged every time the power returns and
its high state of charge is maintained to ensure the longest possible battery life.
In new recorders the battery can be discharged and the clock reset. After correct installation of
the device, the date and time should be set up immediately.

3.1. WORKING STATES OF G-913
The recorder may be in one of the following operating states:
Initialization after turning on the power supply - POWERUP;
Standard work - RUN;
Alarm –ALARM;
3.2. Alarm types
Sensor 1 error
Sensor 2 error
No communication between module and usb flash
All alarms are indicated in the same way, the red LED works in the following sequence:
3 signals | break

3.4. Description of the conditions for transitions between states:
From POWERUP (after about 5 seconds from turning on a power supply):
to RUN mode –after making sensor calibration and stabilization of power supply
from RUN mode:
to ALARM mode –after detecting a fault of one of the sensors
from ALARM mode:
to RUN mode –when the sensor failure is removed
IV. STATUS INDICATION
The device is equipped with a two-color LED. Diodes behavior is described below.
Green:
During normal operation - 1 beep / 1 second
When downloading data - 4 beeps / 1 second
Process ended successfully - continuous indication
Red:
During normal operation - no indication
Alarm occurred - 3 beeps | brake
Process ended successfully - 2 beeps | brake
If more than one alarm occurs, the alarm codes are displayed one after another. The alarm states
are recorded in the register as Err + (sensor opening) and Err (sensor short-circuit) instead of the
registered temperature.

POWER LOSS
If the recorder detects a loss of the main power supply, after the voltage recovery, information about
the date and time of the power supply return and the duration of the decay is recorded in the log.
V. STANDARD WORK
The device has the task of recording the indications from two temperature sensors. The
device starts to work after approx. 5 seconds. since the power is detected, the recorder performs
the first measurement. Each subsequent measurement is saved at a specific frequency (default: 5
min). The device can store 30,000 measurements. Data recording is circular, i.e. after overflow of
memory the oldest measurements are overwritten, thus the last 30000 measurements are
constantly stored in memory. Mixing data to a USB drive does not delete them from the recorder.
Each correct data registration is confirmed by a short blink of the diode.
During the operation of the device, it is possible to read the measurement register at any time,
and change the date and time settings.
DO NOT REMOVE THE USB HEADER FROM THE SOCKET DURING
DATA DOWNLOAD –LOOK AT POINT 6!
THIS WILL DAMAGE FILES AND DAMAGE USB STORAGE DEVICE!
Writing data to a USB drive can take from a few seconds to several minutes depending on the
hardware characteristics of the media and the amount of data written on it!
5.1. Date and time changing
To change date and time you need to plug in USB storage device with saved text file named
"CLOCK.txt" to the USB connector.
Text file should be in the following format (see Fig 2.):
D: yyyy.mm.dd T: HH: MM
Where:
yyyy –year,
mm –month,
dd –day,
HH –hour,
MM –minute,
Warning!!!
Omitting the configuration variables "D:" and "T:" will bypass the change of date
and time, and these variables are necessary to properly decode the file and save
the file REPORT.txt in which additional information will be attached.

5.2. Configuration files
Configuration files should be placed on a flash drive (fat32) in the root directory. The memory
device can only be removed when the green diode lights up permanently and the red diode
operates in the following sequence: 2 signals | break
1) Default settings reset
File name: factory_reset.txt
Data to write in file: “2485”
Action: The logger resets, clears logs, and maintains off until main
supply is turned on again
2) Log clear
File name: clear.txt
Data to write in file: none
Action: Clears all logs in module

PPUH „GECO” Sp. z o.o. ISSUE I AS OF 2023.02.20
3) Language
File name: lang.txt
Data to write in file: L:XX (where XX is a language code (PL –polish, EN –english,
DE –german, FR –french
Action: Changes the language in generated files to the set as above.
If the data in the file or the incorrect language are not saved,
a report.txt file will be created on the flash drive
4) Timeout setting
File name: timeout.txt
Data to write in file: T:XXX (where XXX timeout between temperature data
readings from 1 to 900sec)
Action: Changes sensor reading timeout and logging. If the data in
the file or the recording are incorrect, the timeout value will
not be saved, a report.txt file will be created on the flash
drive
5.3. Reading of registered measurements
At any time during the device operation, it is possible to read the data registered on it. There are
two ways to read.
1) Reading of recorded data without using a configuration file
After plugin USB memory in without a configuration file on it you will save on this USB memory
device 30 000 last registered measurements.
The .txt file with temperature data will be saved into the flash disc. File name:
G913_XXX_R_DDMMRRRR_HHMMSS
2) Reading of recorded data with using a configuration file (see Fig 3.)
After plugin USB memory in with a configuration file on it named „READ.txt”, registers
could be saved in ways shown below:
Reading a certain number of registers (from 1 to 30,000)
In the file "READ.txt", write R: XXXXX
where XXXXX is any number between 1 and 30,000 corresponding to the number of
read entries
