Introduction; Assembly And Installation - Velp Scientifica VTF Manuel D'instructions

1. Introduction

The Thermoregulator is ideal for many applications and meets the most demanding
requirements in terms of precision, reliability and flexibility of use thanks to the application of
Fuzzy Logic technology. The Fuzzy Logic electronic automatically adapts thermoregulation
to the varying factors such as power, load and thermal dispersion specific to each
application, optimizing both overheating and oscillations around the temperature set-point.
The accuracy and precision of thermoregulation at each end the scale and whatever the
volume being processed, is a fundamental characteristic of the Vertex.
WARNING: if the Thermoregulator is connected to an instrument different than the VELP
Scientifica AREX, AREX DIGITAL PRO, AREC.X or PW10, please check the compatibility of
the DIN 5 pole connector as illustrated in wiring diagram in this manual.
NOTE: the most precise results are obtained measuring aqueous solutions temperature.
The microprocessor offers various other functions:
• a working time of up to 24 hours and 59 minutes can be set with automatic switch off;
• the maximum sample temperatures reached during the test can be recorded.
The structure is made of a non-scratch technopolymer resistant to chemical agents and
offers a high level of IP54.
The instrument has an in-built safety and control circuit which is constantly
active and shuts-down the thermoregulator immediately in the following
situations: the temperature probe is not connected; the temperature probe is
faulty (cut-off or short-circuited), the temperature is out-of-range and/or the
probe is not inserted inside the sample.

2. Assembly and installation

Check the integrity of the unit after unpacking.
The box includes:
•
Thermoregulator, with power cable for connection to VELP Scientifica AREX, AREX DIGITAL PRO, AREC.X and
PW10
•
Pt100 temperature probe
•
Instruction manual
Connecting the Pt100 probe
Connect the probe to the Thermoregulator as shown on Fig. 2.
NOTE: the mains cable must remain far away from the hot plate.
Installing the VTF
The VTF has an innovative integrated system to simplify
installation on the support rod and facilitate the positioning of the
Pt100 probe in the most commonly used containers.
The two clamps allow height-regulation whilst a sliding
clamp allows horizontal regulation (Fig. 3).
Using the VTF with magnetic stirrers
The power cable is suitable for connection to the most common heating magnetic stirrers with a dedicated socket for the
remote control of the heating plate such as the VELP Scientifica models AREX, AREX DIGITAL PRO and AREC.X. The
socket must supply a tension of between 9 and 15V DC. The integrated installation system allows the instrument to be
installed on support rods with a diameter of between 10 and 13 mm.
