Application and short description
The TR640IP 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 TR640IP monitor up to 6 sensors simultaneously. The user can assign several limit values to
the 4 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.

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
•
4x relay outputs (1 changeover each)
o
Alarm K1 (11/12/14) … K4 (41/42/44)
•
Fault message for sensor break, short circuit and device fault freely configurable on each of
the 4 relays
•
Modbus TCP
•
Wide range power supply AC / DC 24
– 270V
•
Integrated web server for the measurement query, configuration and for firmware updates
Functions / settings
Alarm:
•
Each sensor can be assigned
to each alarm (relay K1 … K4).
o
However, 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.
o
Caution! 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
o
The function “2 of x” triggers the alarm only if at least 2 of the sensors parameterized
for this alarm fulfil the alarm conditions
o
If only 1 sensor assigned to an alarm, this function cannot be activated.
•
Rate of change of temperature (ROCOT)
o
ROCOT 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.
o
ROCOT time
▪
If the calculated value ((slope * time) + current measured value) exceeds the set
switch-off temperature, the alarm switches on.
o
ROCOT switch back conditions
▪
Actual measured value must be less than “alarm off” and slope must be
negative.
•
Locked alarm
o
Each alarm can be set to “locked” yes or no
•
Relay function
o
On at alarm
o
Off at alarm
o
Man
ually on (if a relay is set to “manual”, it permanently retains this state)
o
Manually off
