3 Device description
The flow controller extends the function of the constant temperature equip-
ment by regulating the heat transfer liquid flowing to the application to a
set flow rate (= volume flow). You can adjust the desired set point using
the constant temperature equipment. The main menu of the constant tem-
perature equipment is extended by the functions of the flow controller. The
control valve in the flow controller is controlled and all status queries made
via the LiBus connection between the constant temperature equipment and
the flow controller. No setting options are available on the flow controller.
The flow controller generally limits the temperature range of the constant
temperature equipment to a minimum of -40 °C and a maximum of 90 °C
on XT devices or a maximum of 140 °C on P devices.
The flow controller has an internal bypass. The electronically controlled
bypass is used to adjust and regulate the flow rate.

4.1 Install device
WARNING!
Overloading of the casters or rolling away of the device
Impact, crushing
Position the device on an even, non-slip surface with a
sucient load carrying capacity.
Actuate the caster brake when setting up the device.
Do not place heavy parts on the device.
Recommendation for installation of the devices:
nThe site must be level and insensitive to moisture.
nDo not cover the ventilation openings of the flow controller.
nIf the local conditions require a dierent installation, the following cri-
teria must be taken into account:
Long hoses between the flow controller and the application have a
higher flow resistance. As a result, the target flow rate may not be
achieved.
Long hoses could promote temperature changes.
The site must be checked to ensure that it complies with the
ambient conditions.
nThe flow controller should be placed as close as possible to the appli-
cation. This minimizes dead time, which has an unfavorable eect on
control quality.
nIf necessary, an extension cord must be used for the LiBus connection
(EKS 068 extension cord LiBus 5 m gray).
1. Position the flow controller between the constant temperature equip-
ment and the application. Position the constant temperature equip-
ment to the left of the flow controller, and the application to the right
of the flow controller.
This arrangement allows the temperature control hoses to be kept
as short as possible.
2. Engage the locking brakes of the front casters.
4.2 Connect the hoses and LiBus cable
CAUTION!
Bursting of the hose and leaking of heat transfer liquid.
Scalding, frostbite, slipping hazard
The temperature, pressure and media resistance of the
hoses must be suitable for the respective application.

The pressure indication of the pump on the Integral IN display
switches to the measured pressure level in MID 80.
In the basic window of the constant temperature equipment, the pressure of
the heat transfer liquid at the outlet of the flow controller is displayed in the
direction of the application. Next to it the corresponding measured flow in
the direction of the application.
Please note:
nOnce the flow control has been activated (Status on ), the pump power
is automatically controlled by the flow controller.
nThe application (e.g. glass apparatus) and hoses must be suitable for the
resulting pressure (maximum pressure of the pump in the Integral XT
7 bar On the Integral thermostat P 10).
If the adjustable maximum pressure is exceeded, the constant tem-
perature equipment stops and reports the gage pressure alarm.
