Brief operating instructions
1 Brief operating instructions
This brief instruction shall give you the possibility to operate the unit quickly. For safe operation
of the unit it is absolutely necessary to read carefully all the instructions and safety notes!
1. Assemble unit and add items as appropriate (➾ Section 5).
Take care of the hose tubing connections (➾ Section 5.1. and 5.4.).
2. Fill the unit with corresponding liquid. (➾ Section 5.3.).
The units are designed for operation with non-flammable and flammable liquids to
EN 61010-2-010. ! Take care of the level of the bath liquid! (➾ Section 5.2.)
3. Connect the unit only to a socket with a protective earth (PE) connection.
Compare the information on the rating label with the supply details.
4.
5. Switch on at the mains switch
6. Setting of the functions
Using a screwdriver, set the overtemperature cut-out point to a value clearly
above ambient temperature (➾ Section 6.5.1.).

Unit description
3 Unit description
3.1 Unit description
The immersion thermostat E 100 has a device for fixing the immersion thermostat to the bath vessel
(clamping bracket). An adapter is supplied for the deep-drawn LAUDA baths 003, 011, 019 and 025.
The type designation of the Ecoline bath/circulation thermostats consists of the control unit E 100 and the
type of bath.
Example: Control unit E 100 and bath 003 produces Thermostat Type E 103.
The letter T (for "Transparent") refers to the baths made of polycarbonate. Type E 103 is supplied with
bath cover. For other baths made of stainless steel bath covers are available as accessory
10. Accessories).
(➾ Section
3.2 Pumps
All units are supplied with a pressure pump with vario drive. The pump has an outlet with a rotatable bend
(Immersion Thermostat) which is connected to the pump nipple for external thermostating circuits
(bath/circulation thermostats). An additional outlet provides circulation inside the bath. By turning the
setting knob it is possible to choose between both outlets or to divide the flows.
The pump chamber of immersion thermostats is rotatable in a restricted way to reach an optimal
circulation. The pump can be used up to viscosities of 150 mm²/s during heating up. To get an optimum
accuracy of control a viscosity of 30 mm²/s is recommended.
One of five pump output steps can be selected using the operating menu.
On small bath thermostats (e.g. E 103 or E 106 T) and with operation as bath thermostat it is advisable to
use output step 1. The advantage is a low heat generation while having a uniform circulation, that means,
that the unit can work without cooling down to just above ambient temperature.
When operating as circulation thermostat with an external circuit it is preferable to use a larger flow
setting in order to ensure a small temperature difference, especially at higher temperatures and in
conjunction with oil as the bath liquid.
The pump pressure outlet can be closed off without causing any damage to the pump.

Unit description
3.3 Temperature indication, control, and safety circuit
The unit is provided with a 7-segment LCD-Display (3 ½ places) with additional symbols for indicating
bath temperature and settings as well as operating states.
The setpoint is input and additional adjustments can be made using either two or three keys
A Pt 100 temperature probe is used for measuring the actual temperature and for control. A second Pt
100 serves as temperature probe for the safety circuit (overtemperature protection) which is independent
of the control function.
A low-level cut-out switches off the heating on both poles in order to prevent dry operation of the heater.
The pump is switched off through the electronics. The setting of the overtemperature cut-out is adjusted
with a tool on a potentiometer and is always limited to 5 °C above the operating temperature range.
All settings and fault messages are stored in the memory on supply failure or when the mains switch is
set to OFF.
The tubular heater is controlled from a modified PID controller through a triac circuit specially designed to
be unaffected by supply variations and interference.
3.4 Materials
All parts which come into contact with the bath liquid are made from high-grade materials appropriate to
the operating temperature. These are rust-free stainless steel, the plastics PPS, polycarbonate (bath 006
T, 012 T, 015 T, 020 T) and fluoride rubber.
4 Unpacking
After the unit and accessories have been unpacked they have to be examined for possible transport
damage. If there is any damage visible on the unit, the forwarding agent or the post office has to be
notified so that the shipment can be examined.
Standard accessories:
Bath cover E 103 only

e) Remove the reference thermometer, which shows e.g. 44,8 °C.
f) Select CAL on the display and go forward as mentioned under point 1-7 (see
above).The actual bath temperature switches from 45°C to 44,8°C and the unit starts to
heat up until the actual bath temperature has reached 45°C. (! the reference
thermometer should also indicate 45°C).

Safety notes
7 Safety notes
7.1 General safety notes
A laboratory thermostat is intended for heating and pumping liquids according to the needs of the user.
This leads to hazards by high temperatures, fire, and the general hazards by the use of electrical energy.
The user is largely protected through the application of the appropriate standard specifications.
Additional hazards may arise from the type of material being thermostated, e.g. when going above or
below certain temperature levels or through breaking of the container and reaction with the thermostating
liquid.
It is not possible to cover all possibilities; they remain largely within the responsibility and the judgement
of the user.
The unit must only be used as intended and as described in these Operating Instructions. This includes
operation by suitably instructed qualified personnel
The units are not designed for use under medical conditions according to EN 60601-1 or IEC 601-1 !
7.2 Other safety notes
•
Connect the unit to a grounded mains power socket.
•
Parts of the bath cover may reach surface temperatures above 70 °C when operating at higher
temperatures. Take care when touching it!
•
Use suitable hoses ➾ Section 5.3.
•
Protect tubing with hose clips against slipping off. Prevent kinking of tubing!
•
Check tubing from time to time for possible material defects.
•
Heat transfer tubing and other hot parts must not come into contact with the supply cable!
•
When using the thermostat as circulation thermostat, failure of tubing may lead to leaking of hot liquid
and become a danger to personnel and objects.
22
•
When no external consumer is connected to the thermostat the pump outflow connection must be
closed (use closing plugs) or linked to the return.
•
Don’t change the pump connections with the connections of the cooling coil!
•
Allow for expansion of the bath oil at elevated temperatures
•
Depending on the bath liquid used and the mode of operation it is possible for toxic vapours to be
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
Safety notes
produced. Ensure appropriate ventilation!
•
Immersion thermostats have to be fixed carefully at the bath vessels!
•
Only use bath vessels which are appropriate for the intended operating temperatures!
•
When changing the bath liquid from water to oil, for temperatures above 100 °C, carefully remove all
traces of water, also from tubing and from the external consumer, otherwise ! danger of burns
through delayed boiling!
•
The cooling coil with the cooling water has only to be used for operating temperatures below 100°C.
At higher temperatures! danger of hot vapour to be produced!
•
Always pull out the mains plug before cleaning, maintenance or moving the thermostat!
•
Repairs on the control unit and the refrigeration system must be carried out by properly qualified
personnel only!
•
Values for temperature control and indicating accuracy apply under normal conditions according to
DIN 58966. High-frequency electromagnetic fields may under special conditions lead to unfavourable
values. This does not affect the safety.

8.1 Cleaning
The unit can be cleaned with water adding a few drops of detergent (washing up liquid), using a moist
cloth..
Before cleaning the unit, pull out the mains plug!
Water must not enter the control unit!
−
Carry out appropriate detoxification if dangerous material has been spilled on or

−
Method of cleaning and detoxification are decided by the special knowledge of the
user. In case of doubt please contact the manufacturer!
Before any maintenance and repair work pull out the mains plug!
Repair on the control unit must only be carried out by properly qualified personnel!
If a fuse blows (! supply indication not alight) fit only fuses as specified (2 x T 16 A; 1 x
