1. General
1.1 Safety
The user manual must be carefully read, understood and followed by all persons who install, use,
maintain and check the product.
The product can fulfil its intended functions only if it is installed, used, maintained, cared for and
checked in accordance with the instructions provided by SICK AG.
1.2 Installer and Operator’s Responsibilities
It is the installer and operator’s responsibility to ensure that all VICOTEC320 devices are installed
and used in compliance with all international, national and local regulations and requirements. The
gas warning device must be checked by an expert for correct installation and functioning before
starting the measuring operation.
The installation should only be carried out by trained installation technicians, taking into account the
current safety procedures for control installations.
The required equipotential bonding connections (also e.g. secondary potential to earth) or earthing
measures are to be carried out according to the respective project regulations. Make sure that no
earthing loops are created in order to avoid undesired interference in the measurement electronics.
It is necessary to follow all instructions as well as the user documentation.
1.3 Maintenance
It is recommended that the equipment is to be inspected on a regular basis. Performance deviations
can be corrected based on regular maintenance. Recalibration and parts replacement can be per-
formed in the field by a qualified technician using the appropriate tools.
Regular maintenance is to be carried out according to the instructions.
1.4 Limited Warranty
SICK AG accepts no liability in the event of improper or incorrect use of the device. The installer and
operator are solely responsible for the design and use of the product. If the product is not used,
maintained or repaired in accordance with the instructions for use, warranty and product liability
claims as well as claims arising from any guarantees assumed by SICK AG for the product will be
forfeited.
1.5 Part Disposal
The appliance can be disassembled into its components, which can be recycled as raw
materials.
•Dispose of electronic components as electronic waste.
•Batteries must not be disposed of with household waste. The battery and the
appliance must be disposed of separately in accordance with local waste dis-
posal regulations.

4.3 Measuring Point
The term Measuring Point (MP refers to a sensor connected to the VICOTEC320.
For a sensor with analog 4–20 mA signal the display shows AP = Analog measuring Point.
With AP, the subsequent number indicates the number of the analog input used.
AP11: This is the measured value of the analog sensor head connected to analog input 11.
5. Code Level
All inputs and changes are protected by a 4-digit numeric code (= password) against unauthorised
intervention according to the regulations of all national and international standards for gas warning
systems. The menu windows of status messages and measured values are visible without entering a
code.
The access to a code level is cancelled if no button is pushed within 15 minutes or if you return to
start menu.
The Adjustment Tool is only protected by code level 4.
Code level 4 (password 1234, code not changeable)
Code level 4 allows the operator after activation of the operation mode “Service Mode” to read all
parameters as well as all test functions of the alarm relays, analog outputs and LCD.
•Manual test function of the alarm relays (functional test of the connected actuators),
•Manual test function of the analog outputs (functional test of the connected actuators),
•Manual test function of the LCD (functional test of the LCD display and the LEDs).

6. Menu Overview
Start menu with display of the company name and the CO sensor by default. The tool automatically
tries to communicate with the CO sensor.
After starting, the Adjustment Tool automatically searches for the connected sensor. In the process,
the gas types are scrolled through. If the connected sensor is found, the display stops with the no-
menclature, gas type and unit. If the data connection to the sensor is lost, the automatic search starts
again.

6.5.1 Maintenance Interval
Input of the maintenance interval in days. If you enter < 10 days, the function is not active.
Sensor head maintenance interval:
A standard maintenance interval (maximum value) is stored in each sensor head (e.g. flammable
gases 200 days, see data sheet). This value can be reduced to a minimum of 30 days. A pending
maintenance message can only be acknowledged by a calibration at the sensor head.

6.5.2 Average Function
Info: The alarm function is not set in the sensor, but in the VICOTEC320 (see operating manual). The
average function is therefore not supported in the VICOTEC320.
6.5.3 Power-On Time
Electrochemical cells need a warm-up period, until the measuring process reaches stable conditions.
During this warm-up period the sensor signal can lead to an unwanted triggering of a pseudo alarm.
Therefore, the Power On Time is started at each basic unit and each sensor head after power-on or
voltage recovery. While this time is running out, the device is in special mode and does not activate
alarms. Power On Time appears in the starting menu. During this phase, the sensor head transmits
"Warm-up time" instead of the measured value.
The Power On Time of the individual components may be different. Only when the longest time has
expired, the system starts the measuring operation.

6.6 Operating Data
This menu is for retrieving relevant operational data of the sensor head and the basic unit. No changes
or interventions are possible
Note: The operating data is transferred to the non-volatile data memory EEPROM once a week and
saved. In the event of a power failure, information may therefore be missing for up to 7 days.
Press the key to read in the operating data. The text 'Please wait...' appears during the read-in
process. If the operating data could not be read in, the display returns to the previous menu item. As
soon as the operating data could be read in, the first subordinate menu item is displayed.

6.7.1 Zero Point Calibration
Use the calibration adapter from the gas adjustment kit for the gas feed. The correct flow rate is
already preset.
Step 1: Display of the current value.
Apply zero gas according to instructions. (No
calculation/adjustment is made here yet.)
Start calibration process
Step 2: Calculation of the new zero offset.
During calculation an underscore in the 2nd
line runs from left to right and the current
value drops to 0.
When current value is stable, press
= terminating the calculation of the new value
Step 3: Save the newly calculated zero offset
”SAVE“ is displayed, as long as the function is
executed.
After the value has been successfully stored, a
square appears on the right for a short time =
Zero point calibration is finished and new zero
offset has been stored with success.
The display automatically goes to step 1: Dis-
play of new zero point
During the calculation phase, the following messages may occur:
Message
Description
Current value too
small
Sensor element defective, replace sensor head.
Current value too
high
Wrong gas for zero point calibration
Message appears if current zero point measurement value is too high (> 10 % of the AD
transducer range, denpendent on gain, not on measurement range).
Current value
unstable
Is displayed as long as the deviation between 2 measuring cycles (100 ms) is
> 3 %. It automatically extinguishes when the sensor signal becomes stable.
Internal error
Is displayed if calibration is not possible, e.g. in the event of serious sensor errors (replace
sensor element) or during the burning-clean process.
Time too short
Message appears if the change in the calibration factor is so great that a stabilisation time
must be waited for. An internal timer (20 s) starts. If the timer expires and the actual value is
still unstable, the text continues to be displayed. The process starts again. If the value is stable,
the actual value is displayed again and the calibration process continues. If this cycle is
repeated several times, there is an internal error. The calibration process must be cancelled
(exit calibration menu) and the sensor head replaced.
Table 7: Possible Messages during Zero Point Calibration
If the zero offset calibration is aborted, the offset value is not updated. The sensor head continues
to use the “old” zero offset.
