Area of application / functional method

Application example for the electric bench heating: The control variable is the bench temperature.
This is measured by means of the remote sensor at the heating mat level. The appliance comprises
the control module for setting the desired temperature and a temperature sensor which measures
the temperature and communicates the measured value to the control module

.

Functioning

The controller measures the temperature by means of a remote sensor which is placed inside
the building component. In case the temperature adjusted at the set value knob is underrun,
the contact with the heating is closed down (scale 1 ... 5 corresponds to ca. 10 ... 50 °C
temperature). The active state of the heating system is indicated by the red lamp. The heating
system can be deactivated with the switch. When connecting the phase to the terminal ,
the controller decreases the adjusted set value by approx. 5K. The green lamp indicates the
active state of this energy saving mode.

Opening the controller

·Lift out the thumb wheel (1) carefully using a screw driver

·Unscrew the fixing screw (2)

·Remove controller cover (3)

·Take off intermediate frame (4) and switch frame (5)

Installation controller

Caution, switch off mains voltage at all poles before installation!

·Electric connection according to ‘schematic diagram‘ with screw terminals

·Cross section of solid wire is load-dependant 1,5 ... 2,5 mm

·No protective conductor

·Install controller (7) in the flush-mounted box on the wall by means of a support ring (6)
and screws.

IMPORTANT NOTE

CAUTION: Work on the 230 V mains supply may only be carried out by a qualified

electrician. The national (Germany: VDE) and local electricity supply company
safety regulations must be complied with when connecting the appliance.

CAUTION: In the event of a fault, mains voltage may be present on the sensor
cable. Connecting cables must be straight and the insulation stripped by about 6 mm.

CA

UTION: Type of protection IP 20 = no protection against penetrating water!

The controller must be protected from moisture and water vapour (relative air
moisture < 60%).

Please refer to our data sheets. Valid data sheets and test certificates can

General

The currently valid VDE and DIN regulations as well as the technical connection conditions (TAB)
from the local electricity supply company must be observed during the installation of control
units! Resistance measuring may only be carried out with a resistance tester. Insulation
measurements may not be performed.

Fitting the measuring probe

The standard probes have a length of 3 m. Get in touch with us prior if you are laying the probe
lines directly near power cables with frequent switching operations. Probe lines may be extended
by a maximum of 500 m.

A semiconductor (NTC) is used as a temperature probe; it is cast integral inside a 5 x 50 mm
protective sleeve and is connected using a flexible connecting lead 2 x 0.75 mm
silicon sheath. Temperature probes with silicone leads should be used for ambient temperature
exceeding 70 °C. These are connected either directly on the control unit or via a terminal box.

The location in which the temperature probe is mounted depends on the type of heating and the
task of the electric heater. The rule that generally applies is that the probe should be mounted
in the place that is most suitable for acquiring the reference temperature (system temperature).
For example, if the bench heating is to provide temperature equalisation for the surface, the
temperature probe should be installed in lines near the surface. In the case of pipe accompanying
heaters using a heating loop or between the heating circuits, these are offset by about 90 °C
with a simple parallel layout. The temperature probe is situated directly on the tube underneath
the

insulation.

If limitation transfer elements are used for pipe accompanying heaters, then the corresponding
temperature probe is fitted in parallel about 1 m from the heating line.

Fitting the measuring probe

All the measurements must always be taken while the probe lines are disconnected.

Commissioning

The functionability of the entire control equipment and control system is tested after the control
equipment and control system has been assembled and the installation of the control equipment
and the measuring probe(s). The temperature is cooled down using cooling spray to below the
required switching point or is carefully warmed up to the switch off point. That way, it is possible
to control at what point the heating switches on using a clip-on ammeter or voltmeter. If you
only want to test the function of the control equipment, the temperature can be simulated with
a corresponding resistance between terminal 9 and 10.

The control equipment is designed in such a way that there is a potential-free relay output
available (connection terminals 4 and 5). Switching is possible over the relay on the control
equipment up to a heating capacity of 1kW approx.

The control equipment is equipped with a potential-free fault alarm output. This is especially
intended for the mandatory monitoring of the temperature probe if sprinkler systems are being
heated. This can also be used to monitor whether separate threshold values are exceeded or fall
short.

The fault alarm output is closed when the control equipment is in an ON state between
connections 6 and 7; in the event of a fault, the relay opens and the type of fault and the
measured temperature are displayed alternately.
