14 Four castors (front castors with parking brake)
In addition, there is an overflow pipe on the rear of the device (con-
cealed)
3.2 Mains switch
The devices have a mains switch on the right side of the device. This is a
rotary switch. Position [0] switches the device off, while Position [I] switches
it on.
Mains switch for three-phase devices
The automatic fuse may only be switched on by a qualified electri-
cian!
The rotary switch is not designed as a safety switch. The three-
phase devices have a separate automatic fuse built in. If the
automatic fuse trips, contact the LAUDA Constant Temperature
Equipment Service department.
3.3 Hydraulic circuit
The hydraulic circuit in the Integral XT FC consists of a piping system
through which the heat transfer liquid flows under pressure.
All devices are equipped with an 8-stage, hermetically sealed (magnetically
coupled) pump. The pump performance can thus be optimally adapted to the
respective task: High pump pressure, if, for example, long hoses lead to the
external consumer.
A programmable maximum value of the pump pressure allows effective pro-
tection of pressure-sensitive applications by switching off to standby mode
when the preset value is reached.
In addition, either the flow rate can be measured and regulated within a
defined range or the pump pressure can be preset via pressure control.
