Now connect the additional heat exchanger with the Vicat needle device.
1.) connect delivered hose with T-switch and with the front port at additional heat exchanger
2.) connect hose running to the basin with the rear port at additional heat exchanger
3.) connect 3
rd
plug of the Y-wire with additional heat exchanger
Figure 17: connecting additional heat exchanger
Connect power cables and switch on both devices.
Additional heat exchanger is controlled also by temperature controller of the Vicat device.
Caution!
You could use the second heat exchanger to heat up the water in the basin theoret-
ically, but the recommended maximum temperature of 45°C is reached by the inter-
nal heat exchanger.
Components inside Vicat needle device must not be exposed to more than 60°C!
3.2.4 Consistency plunger
To check the normal consistency by a Vicat device you can use a consistency plunger, which is available
as optional accessories. It has the same weight like the Vicat needle to ensure an absolute weight of
300±1g for the whole drop rod.
Figure 18: consistency plunger
To replace the needle with the consistency plunger, move the drop rod to the maintenance position (sec-
tion 4.6). Open the flap and take out the drop rod. Loosen the stud screw and remove the needle from the
drop rod. Insert the consistency plunger and tighten the stud screw. Insert the drop rod into the device and
close the flap. Leave the maintenance position. In the VicatMPM software under "Standard" (for the de-
sired sample) select the item "Normal Consistency". Start measurement on sample, the measurement is
carried out. Then move the drop rod back to the maintenance position and replace the consistency plunger
with the needle.
