a warning message:
DANGER draws attention to a danger which will lead to
death or serious injury if not avoided.
WARNING draws attention to a danger which can lead to
death or serious injury if not avoided.
CAUTION draws attention to a danger which can lead to
minor or moderate injury if not avoided.
NOTICE
Important instructions and information on effective,
economical & environmentally compatible handling.
2.2 Safety Instructions
The safety instructions given in this clause must be carefully
observed.
DANGER When using the BARTEC TRACE COMAND,
make sure that the handheld device with the software
installed on is suitable for the operating environment.
Your local BARTEC reprehensive will help you to find a
suitable device.
If the BARTEC Trace Command is incorrectly executed,
the settings of the connected ESTM/ESTM-L can be
changed, affecting the operational reliability of the entire
heating system! Onlytrained technical personnel may run
the program in online mode.
WARNING this manual is only an additional information
for all technical details please observe the Installation
instructions
NOTICE

3.1 About this manual
This manual is applicable for firmware version 3.4.6
3.2 Bluetooth ID
The serial number of the ESTM/ESTM-L is used to identify the
device when connecting to Bluetooth. The serial number is
equivalent to the MAC-Address of the Bluetooth-Module.
3.3 Factory set default device-
password
ESTM-L
„Device pin (digits)“
This password should be changed and only authorised
persons should be supposed to know. Otherwise some
unauthorized persons are able to change all settings.
What might interrupted our processes or it can lead to a
damage of system or equipment
Password change see: 4.8.8 System Data
3.4 Temporary Pin
Temporary Pin is 3 digit Password that is created by the ESTM /
ESTM-L and shown on the display of the device. The hexadecimal
numeric code is used for this password. That means the numbers
from 0-9 and the charters A-F are used. This key is re-created each
time a change is requested to the device.
That password will make sure that you have selected the correct
device. And it will help to prevent unauthorised access to the
System.

4.8.1 Controller
Controller Response:
Asymmetric hysteresis up two point controller.
If the hysteresis is set, too low, increased contact
abrasion may result. This will significantly reduce the
lifetime of the device.
If the hysteresis is set too high, the temperature of the
heater or the work piece may increase. This can lead to
an exceeding of the process temperature.
Set the hysteresis as low as necessary and as high as
possible.

4.8.2 Limiter
The Limiter option is only available with an ESTM-L.
The limiter of the ESTM-L follows the requirements for Controlled
design of the IEC/IEEE/EN 60079–30–1.
SIL II Limiter:
The Limiter value is set by an coding element. Coding element will
be connected to a marked terminal in the enclosure. Only use
Original BARTEC coding element. For detailed information see
Installation manual.
To reset the limiter see table below.
The limiter is not adjustable by software to meet the Requirements
of SIL 2
The function “pre alarm limiter sensor” is just an
adjustable Alarm value. It will not trip the Limiter. Only an
alarm will be send by Modbus.

4.8.3 Soft limiter
This function is available for firmware version 4.0.0 or higher.
Use of the Soft Limiter function as a limiter is not permitted for
ATEX and IECEx applications according to
IEC/IEEE 60079-30-1.
Explosion protection is not ensured by this function.
Use hardware limiter of ESTM-L (SIL II) as limiter for ATEX
and IECEx applications according to IEC/IEEE 60079-30-1.
To activate the smart limiter set the Sensor Mode to both and
the Controller mode to soft limiter see also chapter 4.8.6
Sensor Setup.
If the set temperature limit value (Set Point Soft Limiter) is
exceeded, the load relay or the load is switched off
permanently until a reset is done. This reset can be done by
the user or by means of the smart reset function.
Reset is possible if actual temperature (Actual Value Soft
Limiter) at the sensor 2 (TC2) is lower than the set point (Set
Point Soft Limiter) minus the set hysteresis (Hysteresis Soft
Limiter).
Sensor errors (wire breakage, short circuit, etc.) are detected
automatically. In the case of a sensor error, the load relay or
the load is switched off permanently until a reset is done by
the user.
Smart Limiter Reset
The Smart Reset function automatically resets the soft limiter
when the actual temperature (Actual Value Soft Limiter) at
the sensor 2 (TC2) is lower than the set point (Set Point Soft
Limiter) minus the set hysteresis (Hysteresis Soft Limiter) and
Smart Reset Status is active.
T-Off delay is the time that must have passed after the load
is switched off to enable the Smart Reset.
Remaining T-Off delay shows the remaining time until the
Smart Reset can be enabled.
The Smart Reset status Enabled means that the Remaining
T-Off delay time has expired or the load has been switched
off by the controller.
The smart reset status Wait means Wait until the Remaining
T-Off time has passed.
The Smart Reset status Disabled means that Smart Reset is
not possible because the load is switched on or the
Remaining T-Off delay time has not passed.

Internal power circuit hotspot 125°C
To prevent a high temperature breakdown in case of a
malfunction (temperature at load power circuit higher the
125°C) the device will override the controller relays and force
switching off. This is a self-protection-function of the device. It
should prevent the irreparable blow of the temperature fuse,
that is placed at the internal hotspot.
Internal power circuit hotspot 135°C
To prevent a high temperature breakdown in case of a
malfunction (temperature at load power circuit higher the
