Useful information

The station is controlled via a WiCo� If the WiCo is

mounted on the station, data is exchanged between the

station and WiCo via the contacts (

C

)� The screen of the

WiCo displays the home icon �

The WiCo is equipped with a USB socket (Universal Serial

Bus) with which the WiCo can be connected with station,

the USB icon appears on the screen�

If the WiCo is not connected with station via a USB

cable, the data exchange between the station and the

WiCo via Bluetooth®� In this case, the Bluetooth®icon

is displayed �

Depending on the structure of the building, the WiCo can

be operated at a distance up to 15 m from the station,

using the Bluetooth®connection�

The WiCo could be either installed on the

station

or put

on a safe place where is accessed easily by the user during

operation�

If the WiCo is mounted on the station, the battery is

charged through the contacts (C)�

The battery could also be charged via the USB port on the

WiCo (See “Charging the Battery Pack RB 1“ in “Prepara-

tions“ section)�

Menu (Details):

TEMPERING:

1. Control:

1) Control Mode:

Internal (int): The temperature is regulated according to

the internal temperature sensor�

Extern (ext): The temperature is regulated according to the

external temperature sensor�

2) Control parameters:

Automatic: The optimal control parameters for PID tem-

perature control are determined automatically� This is the

recommended mode�

Selecting "Automatic" allows you to set the dynamics for

temperature control�

Ts must be adjusted to match the response characteristic

(total of all time constants) of the closed loop controlled

system, so that the control variable can deliver a uniform

and measurable change in the control deviation� Ts values

that are too small or too large can lead to instability of the

controller�

Prop_Bp: Proportional Band Maximum�

Prop_Bn: Proportional Band Minimum�

The Proportional Band is the range below (Prop_Bp) and

above (Prop_Bn) the set value in which the control output

value is calculated via the difference between the actual

and the set value and the PID parameters�

Examples of non-optimal settings:

3) Fluids:

Under the option "Fluids", a variety of ﬂuids can be selected�

The selected ﬂuid limits the setting range of the target

temperature� See table in the section “Fluids (Standard in-

formation for IKA ﬂuid)“�

The maximum and minimum temperature values of the

selected ﬂuid can be set within these limitations�

2. Limits:

Under the option "External (ext)", the maximum and mini-

mum temperature for external temperature control can be

set�

Under "l Δ T (int - ext) l", the maximum difference be-

tween the internal and external temperature can be set�

The function limits the absolute temperature difference

between the external system and internal bath during the

heating up and cooling down process� This can protects

sensitive device like the glass reactors from thermal shock

(e�g� glass break)�

°C

t

Fig. 26

Manual: The control parameters for PID temperature con-

trol can be set manually�

"Manual" should only be used in the event of special tem-

perature control requirements�

When "Manual" is selected, the following parameters can

be set for "Internal (int)" and "External (ext)" temperature

control:

Kp: Proportional coecient

The proportional coecient Kp is the controller ampliﬁca-

tion and determines how strongly the control deviation

(the difference between the target temperature and actual

temperature) directly affects the control variable (on-time

of the cooling)� Kp-values that are too large can lead to

the controller overshooting�

Ti: Integral time

The integral time Ti (s) is the correction time and deter-

mines how strongly the duration of the control deviation

affects the control variable� Ti compensates for an existing

control deviation� A high Ti means a smaller and slower

effect on the control variable� Ti-values that are too small

can lead to instability of the controller�

Td: Differential time

The differential time Td (s) is the derivative time and de-

termines how strongly the rate of change of the control

deviation affects the control variable� Td compensates for

rapid control deviations� A high Td means a smaller and

slower effect on the control variable� Td-values that are

too large can lead to instability of the controller�

Ts: Sampling time

The sampling time Ts (s) is the time interval over which the

control deviation is determined and the respective control

variable (dependent on Kp, Ti and Td) is calculated�
