3 Pre-sets
The pre-set programs cover most applications. The required program can easily be selected via the menu
(push button down >2s -> programs). Alternatively, the program can be selected via the web server (page
configuration).
4 Application and short description
The TR660IP is used particularly advantageous wherever several Pt100, Pt1000 sensors or PTC thermistors
are to be evaluated simultaneously:
•Motors or generators, also with simultaneous monitoring of bearing or e.g. exhaust
temperatures
•Transformers, also with additional core temperature monitoring
•Machinery and equipment
Switchgear type TR660IP monitor up to 6 sensors simultaneously. The user can assign several limit values to
the 7 output relays almost arbitrarily. The assignment sensor / relay is very variable programable. Basic
settings such as the monitoring of 3 sensors to the same limit with common message (e.g. when used on
motors or transformers) can be easily selected via the default configurations.

5 Overview of functions
•All measured values can be read at once
•Easy operation with joystick button
•Measuring and monitoring range Pt100, Pt1000 -199,9 … +800,0°C, PTC
•6x sensor inputs (Pt100, Pt1000, PTC), optionally 2 or 3 –wire technology
•7x relay outputs (1 changeover each)
oAlarm K1 (11/12/14) … K7 (71/72/74)
•Fault message for sensor break, short circuit and device fault freely configurable on each of
the 7 relays
•Modbus TCP
•Wide range power supply AC / DC 24 –270V
•Integrated web server for the measurement query, configuration and for firmware updates
•4x analogue output (2x voltage, 2x current) –TR660IP Analog only
•RS485 interface (Modbus RTU) –TR660IP RS485 only
Functions / settings
Alarm:
•Each sensor can be assigned to each alarm (relay K1 … K7).
oHowever, only equivalent sensor types can be assigned to the same alarm. That
means Pt100 and Pt1000 sensors can be combined, but not PTC at the same time.
oCaution! The first parameterized sensor specifies the alarm type (Pt sensor or PTC).
•For each alarm, sensor fault and device fault can be parameterized
•Free adjustable delay times for “Alarm on” and “Alarm off”
•2 of x
oThe function “2 of x” triggers the alarm only if at least 2 of the sensors parameterized
for this alarm fulfil the alarm conditions
oIf only 1 sensor assigned to an alarm, this function cannot be activated.
•Rate of change of temperature (ROCOT)
oROCOT slope (°C / s)
▪If the temperature increase between the measured values is higher than the set
slope, the respective alarm switches on. Even if the set “alarm on” temperature
has not yet been reached.
oROCOT time
▪If the calculated value ((slope * time) + current measured value) exceeds the set
switch-off temperature, the alarm switches on.
oROCOT switch back conditions
▪Actual measured value must be less than “alarm off” and slope must be
negative.
•Locked alarm
oEach alarm can be set to “locked” yes or no
•Relay function
oOn at alarm
oOff at alarm
oManually on (if a relay is set to “manual”, it permanently retains this state)
oManually off
Cyclic relay test
The cyclic relay test is freely adjustable for each relay. It is used on engines for example, to activate fans or
pumps in a fixed cycle for the set time, so that they are moved regularly.

7 Important Information
DANGER!
Hazardous voltage!
Will cause death or serious injury. Turn off and lock out all power
supplying this device before working on this device.
If the temperature sensors are installed in transformers or motors with a voltage >
300V, they must have a double or reinforced insulation suitable for the measurement.
All wires (sensors, reset, ethernet) that are >30m must be shielded. The shield must
be earthed on the side of the device
Reference to isolation of input and output as well as relay contacts: Unless otherwise
noted, the devices have basic insulation accordingly the measurement insulation
voltage of the device. When higher isolation or safe separation is required for the
application, this must be ensured due to additional measures.
Attention!
The temperature sensors are connected to terminals 1T1, 1T2, 1T3 etc.
These pluggable contacts have a special contact material and may only be used for
connecting the sensors.
To use the equipment flawless and safe, transport and store properly, install and start professionally and
operate as directed.

9.3.2 Call via web browser
After calling the IP address, the device logs in the web browser.
9.4 Wire line adjustment
To compensate the line resistance short circuit the wires nearby the sensor, measure resistance and enter
this value for line resistance. With 2-wire connection and a common line for all signals, all sensor measuring
currents will be added on the common line. Thus the value of the compensation line resistance RK must be
calculated as follows:
RK = (n+1) x RL/2 (RL = resistance of two wires, n = number of sensors)
