Description
Using a BVT3000 with BVTE3900 2.4.1
Connect the cable between BVT3000 (plug marked BVTB3500 on front panel)
and plug unit.
The BVT3000 must be equipped with a «E» thermocouple input connector, and
this sensor must be selected in the temperature controller configuration. This ther-
mocouple type is installed in high temperature probes.
For very high temperature experiment up to 600 °C (878K) it is necessary to
close two jumpers (JP11 AND JP12) on the main board of BVT3000 (board
W4P110276C). They select the higher overheating temperature threshold.
Inside the BVTE3900 connect the 2 «FASTON» plugs of the heater output cable
to make the connections A-C and B-D as shown in figure "BVTE3900 wiring dia-
gram" on page 22 (bottom).
The heater CONNECTOR 1 must be installed on the top panel.
This configuration is normally factory set.
Using a BVT2000 with BVTE3900 2.4.2
A slight change of the internal wiring in BVTE3900 is necessary.
Step1) Dismount the cover plate which holds all plugs. The plug (9) "PROBE
HEATER" must be dismounted from the cover plate and the cable disconnected
from the printed circuit and removed.
Step 2) The spare plug located at the end of the cable attached to plug (7)
"BVT2000 HEATER" must be installed at same place.
Step 3) Disconnect the wires with "FASTON" terminations near the plug (7) and
make the connection of the wires A to E and B to F as shown in figure
"BVTE3900 wiring diagram" on page 22. They are coming from the right side
near the electrical fan.
Step 4) Install then the special heater cable between the BVT2000 and the
BVTE3900 (part number W1100628). Connect it on the rear side of BVT2000
plug marked "HEATER" and plug (7) "BVT2000 heater" on BVTE3900.
Connect, if necessary, the "E " type thermocouple coming from probe on the "E"
input on rear side of the BVT2000 and select the same thermocouple type in the
temperature controller configuration.
When this wiring is done, the BVT2000 provides the heater power. The heater led
is now disabled. The safeties included in BVTE3900 become active (coolant flow
and probe heater overheating monitoring). In case of a failure or problem, it
means that the safety thermocouple signal loop is open which turns off immedi-
ately the heater in the BVT2000.
Filling up the coolant 2.5
The tank must be filled with approximately 5 litres of coolant. The cooling is a mix-
ture of pure water and ethylene-glycol. The system is delivered with 3 cans which
must be poured in the tank (we recommend GLACELF from ELF, BRUKER part
