1 Use
The digital temperature controller TC D... is
manufactured according to the guideline 2014/34/EU
and is intended, among other things, for controlling the
temperature of enclosures, cabinets or heat trace
cables.
The TC D... is delivered with the index "J" and can be
switched together on site with the heating source to be
regulated. It is equipped with an external sensor -index
"E"- and with the HI version can be provided with an
additional sensor connection for controlling the heating
source.
The temperature controller approved in Ex zone 1 and 2
for device categories G/ D, in temperature class T4.
2 Explanation of symbols for warnings
and signal words
The safety information warns the user about risks and
provide information on how risks can be avoided.
Safety information can be found at the start of the
chapter before the instructions which may lead to a
hazardous situation. Additional safety information can be
found at the beginning of this manual.
Safety instructions which must be adhered to are
highlighted as follows:
DANGER
DANGER
This sign is warning about an extremely hazardous
situation which, if not heeded, will lead to death or
serious irreversible injury.
WARNING
WARNING
This sign is warning about a hazardous situation which,
if not heeded, may lead to death or serious irreversible
injury.
CAUTION
NOTICE
This sign is warning about a hazardous situation which,
if not heeded, may lead to slight, reversible injury.
NOTICE
NOTE
It is essential to pay attention to this safety advice as you
may otherwise incur material damage.
INFO
Important notes and useful additional information.
3 Installation Instructions
INFO
The device may only be connected up and secured by a
trained person, taking into account the "rated voltage"
and "rated current" specified on the nameplate.
For mounting in hazardous dust areas, certified
components must be used. The connecting cables must
have a fixed installation and must be protected
mechanically.
NOTICE
Only heat-resistant connecting cables may be used.
4 Device Description
The RS 485 interface allows the interconnection of
devices in field bus networks and parameterization at a
PC via the Modbus RTU protocol. The set temperature is
adjustable in 1°C increments.
The device has a two-colour LED light on the side for
determining the status visually.
The digital temperature controller has three analogue
inputs that can each be used as an actual value
encoder:
• An external intrinsically safe KTY temperature
sensor for measuring and controlling the temperature
• An internal temperature sensor for monitoring the
housing
• Optional: The NTC sensor of the heating coil for the
electronic temperature limit

6 Installation
NOTICE
Risk of overheating
The controller housing may only be mounted at a place
where 80°C is not exceeded.
If higher temperatures should be controlled, the
intrinsically safe external sensors have to be attached to
the place to be controlled and the controller housing
outside the heated area.
At higher temperatures, the controller must no longer be
impinged with full power.
Room

Imax 120 V AC 230 V AC

+80°C 4.4 A 530 W 1000 W
Imin = 250 mA
At temperatures below -25°C, the controller switches
over to the "cold-start mode". At the same time, the
output switches to 100% power until the circuit board
exceeds the temperature of -20°C. Thus, in very cold
climatic conditions, it is necessary to ensure that the
connected heating also heats the controller. If a
permanent operating temperature greater than -25°C
cannot be reached, the controller must be heated
separately.
7 Connection
INFO
The device may only be connected up and secured by a
trained person, taking into account the "rated voltage"
and "rated current" specified on the nameplate.
Each heater with integrated TS thermostat must be
preceded by a 10 A fuse or a motor protection switch
with short-circuit and thermal quick release (set to 10 A)
as short-circuit protection. When using a heater without
integrated thermostat, the fuse protection can be
selected according to the cross-section of the supply
cable.
Additional equipotential bonding is required. The
terminal block designated for this purpose has the
ground sign.

If you have ordered the "SMART HEATER software" as
well, then please read the "TC SMART Modbus
Software" operating instructions for individually setting
the parameters and recording the data.
9 Maintenance
The design of the device does not require any
maintenance.
Functional and safety test intervals can be freely
selected by the operator in accordance with the
applicable regulations.
Repairs may only be carried out by the manufacturer in
the factory.
All components have to be kept clean and free of dust
and harmful substances that could lead to excessive
temperature rise.
In the dust Ex area, the applicable requirements of EN
60079-17 and EN 60079-19 must be complied with.
10 Troubleshooting
In the case of failure of the temperature controller or
performance fluctuations, please check the operating
conditions. See also: Installation [}Page4].
If the device is defective, it must be removed and sent
back to the manufacturer for repair.
11 Deinstallation
Disassembly may only be carried out by a trained
person.
DANGER
Risk of fatal injury from electric current!
If contact is made with live components, there is the risk
of fatal injury.
For this reason, switch off the voltage supply, secure
against being switched on again and check that no more
voltage is present.
Disconnect connection line from the clamps and from the
connection socket, disconnect device from bracket and
remove it.
12 Disposal
Disassemble the components of the product, taking the
applicable local labour protection and environmental
regulations into consideration and make sure that the
components are recycled:
• Scrap metal
• Send plastic elements to recycling
• Sort other components according to their material
properties and dispose of them.
NOTICE
Environmental damage may be caused if
disposed of incorrectly!
Electrical scrap and electronics components are subject
to hazardous waste treatment and must only be
disposed of by certified specialists!
The local community authorities or specialist waste
disposal companies can provide information on
environmentally friendly disposal.
