Interfaces And Outputs - IKA HB digital Operating Instructions Manual

Controlling the medium temperature
The medium temperature is limited by the set safety temperature,
controlled by means of a PID controller and measured by the PT 1000
temperature sensor, and the medium is heated up as quickly as pos-
sible without overshooting to the set temperature.
The PID controller adapts to the different tempering media and en-
sures optimum temperature control with minimum temperature drift
and fluctuation.
Optimum control is only achieved when the medium is mixed using a
rotating evaporator piston.
- Set the desired medium temperature between room temperature
and 180 °C by turning the rotating/pressing knob (C). The max.
medium temperature setting is the safety temperature minus 10
°C.
Key "Lock"
The operating settings can be locked by pressing and holding the key
(E) for 2 seconds, preventing any inadvertent changes during ope-
ration. The lock symbol appears on the screen when this function is
activated. (Fig. 10)

Data transfer via IR interface
IR
The device can be operated by computer via an USB interface
using the laboratory software labworldsoft
Note: Please comply with the system requirements together with
the operating instructions and help section included with the
software.
USB interface
The Universal Serial Bus (USB) is a serial bus for connecting the
device to the PC. Equipped with USB devices can be connected to
a PC during operation (hot plugging). Connected devices and their
properties are automatically recognized.
Use the USB interface in conjunction with labworldsoft
eration in "Remote" mode and also to update the firmware.
- Start the heating function by pressing the rotating/pressing knob
(C).
- An animated heating symbol appears on the display. (Fig. 9)
- The heating bath is heated up to the set temperature.
- The set and actual temperature referred to the medium are shown
on the display. (Fig. 9)
Select tempering medium
- If a target value > 90 °C is set, the PID controller is adapted specially
for oil.
- The "OIL" symbol appears on the display. (Fig. 11)
- If the target value is reset to 20 °C the PID controller is adjusted
again specially to water.
- The "OIL" symbol will disappear from the display. (Fig. 9)
Press and hold the key (E) again for 2 seconds to unlock the operating
settings. The lock symbol disappears when function is deactivated.
The heating bath transfers data via IR interfaces. These interfaces are
located on the left display side of the heating bath or on the right
side of the drive unit. Do not place any objects between the two
operating units as otherwise the data transfer may be interrupted!
Remote Mode
Using the laboratory device software "labworldsoft
ry evaporator RV 10 digital/control the device can be operated in
"Remote" mode. In this mode, the device can no longer be hand-
operated. (Fig. 12)
Note: Please comply with the system requirements together with
the operating instructions and help section included with the
software.

USB device drivers
.
®
First, download the latest driver for IKA devices with USB inter-
face from:
http://www.ika.com/ika/lws/download/usb-driver.zip
Install the driver by running the setup file. Then connect the IKA
device through the USB data cable to the PC. The data communi-
cation is via a virtual COM port.
Command syntax and format
The following applies to the command set:
- Commands are generally sent from the computer (Master) to
the lab device (Slave).
for op-
® - The lab device sends only at the computer's request. Even fault
indications cannot be sent spontaneously from the lab device to
the computer (automation system).
- Commands are transmitted in capital letters.
- Commands and parameters including successive parameters are
separated by at least one space (Code: hex 0x20).
