MoniTrace Remote Monitoring Module (RMM2)
The MoniTrace 200N unit independently controls two groups of trace-heating circuits. Remote
Monitoring Modules (RMM2) collect RTD inputs and communicate with the MoniTrace 200N central
control and monitoring unit using a single RS-485 bus.
Overview of Installation Procedure for the RMM2-EX-E
A. Mount RMM2 enclosure and install cables.
B. Connect power and earth wiring and select voltage operating range.
C. Connect RTD cables to the RMM2.
D. Select RS-485 address for the RMM2 and connect the RS-485 bus cables.
E. Initialise or update the MoniTrace 200N network and assign settings for each RTD (using the
MoniTrace 200N control panel).
Note: Installation to be performed by suitable trained personnel.
Note: Keep the MoniTrace Remote Monitoring Module clean and dry prior to installation to avoid
damage to internal components.
Note: When RMM2-E is used for DIN-rail installation in a local customised panel or enclosure,
must be added 10 earth terminals for earthing of RTDʼs and power cables. Terminals should
accept wires from 0.2 to 4 mm2.
Circuit breaker configuration may vary according to local standards / requirements

A. Mount Enclosure and Install Cables
B. Connect Power and Earth Wiring and Select Voltage Operating Range
1. Select a suitable location for the
RMM2-EX-E enclosure.
The enclosure is suitable for use in Zone 2
areas. Do not mount in Zone 1 or Zone 0 areas.
For installations in Zone 1 areas, contact Tyco
Thermal Controls.
Use the dimensions to locate mounting holes
for the enclosure. Mount the enclosure using
suitable screws (hole diameter 6 mm).
2. Install cables
Install power cable(s), RS-485 cable(s) and
RTD cables into enclosure using glands sup-
plied. Keep stopping plugs in unused entries.
3. Select the voltage operating range
Connect the supplied wire jumpers to the
appropriate terminals to select input voltage.
The RMM2 is supplied jumpered for 230 volts.
4. Connect wiring from power source to
designated terminals on RMM2.
Use only copper conductors. Connect power
cable wires to the terminals marked L1 and L2
on the RMM2. If power is being daisy chained,
be sure to maintain polarity of L1 and L2 wiring
for incoming and outgoing wires. The terminals
accept stranded wires from 0.2 – 2,5 mm2.
(0,2 - 4 mm2 solid wire)
5. Connect earth wiring.
Connect the earth wire(s) to the earth terminals
mounted on the DIN rail. The terminals accept
0,8 - 2,5 mm2 solid or stranded wires.

The RMM2 has terminals for 8 three-wire, RTDs
(Pt 100 temperature sensors, to IEC 751-1983);
do not use other types of RTDs. Select RTDs
appropriate for the usage:
MONI-PT100-NH Temperature sensor for
non-hazardous areas
MONI-PT100-EXE Temperature sensor for
hazardous areas
(EEx e II T6, zone1)
Install each RTD in accordance with the instal-
lation instructions shipped with it, and run the
RTD lead wires to the RMM2.
Note: Resistance of lead wires from each RTD
must not exceed 20 Ω (e.g. 150 m with
3 x 1,5 mm2 cable).

6. Connect lead wires from each RTD to the
selected RMM2 terminal block
The RMM2 has 8 terminal blocks to connect
lead wires from 8 RTDs. Each RTD connection
is numbered; the number identifies the RTD,
and determines the order in which the Moni-
Trace 200N displays the RTD measurement.
Therefore, order the RTD connections in a
manner that makes the MoniTrace 200N display
most meaningful.
The RMM2 cover shows the correct wiring
arrangement for the RTD wires. With Raychem
RTDs, connect the two RTD lead wires of the
same colour to the terminals marked “-“ and
connect the RTD lead wire that is a different
colour to the + terminal.
Note: If the RTD lead wires are reversed, the
MoniTrace 200N will give an obviously wrong
temperature measurement.
7. If RTD-shield is not earthed elsewhere,
connect shield to earth terminal.
8. Record the location/identification for each
RTD.
Because the RMM2 terminal connection
number identifies the RTD in the MoniTrace
200N system, it is important to record the
location of each RTD. Use the space below to
record the connections, and label the RMM2
or its enclosure with this RTD identification
information.

D. Select RS-485 Address and Connect the RS-485 Bus Cables
9. Select the RS-485 address for the RMM2
unit.
Each RMM2 connected to a MoniTrace 200N
control and monitoring unit must have a unique
address; if two RMM2s are assigned the same
address, communication faults will result. To
ensure that you assign a unique address to
each RMM2 unit, do the following:
• Review the MoniTrace 200N system layout;
if a layout document does not exist, create
one. If it has not already been done, assign
an RS-485 address to each RMM2 (up to
16) connected to the MoniTrace 200N unit.
To record the RS-485 assignments, use the
installation record of the MoniTrace-200N
Control Unit Installation Manual
(Tyco Thermal Controls document H56680).
• If you are adding one or more RMM2 units to
an existing MoniTrace 200N network, confirm
that the RS-485 addresses for existing RMM2
units correspond to the system layout. You
can do so by observing the MoniTrace 200N
display. When the MoniTrace 200N displays
a temperature, it identifies the RTD with a
two-part tag; the prefix indicates the RMM2
address, and the suffix indicates the terminal
number to which the RTD is connected. For
example, RTD 3-7 identifies an RTD con-
nected to the RMM2 with address 3, RTD
terminal 7.
By checking the RS-485 addresses on an exist-
ing system, you can avoid potential conflicts
that would be confusing and time consuming to
troubleshoot otherwise.
Record the RS-485 address selected for the
MoniTrace Remote Monitoring Module you are
currently installing, and label the exterior of
the enclosure with the address assigned to the
RMM2. For reference, here are the 16 possible
RS-485 addresses: (0 -15 HEXADECIMAL)
0 1 2 3 4 5 6 7
8 9 A B C D E F
10. Set the RS-485 address for the RMM2
unit using the rotary switch provided
Take of the lid and use a flat-blade screwdriver
to rotate the RS-485 address switch to the
desired position. The single character visible
on the switch indicates the RS-485 address

assigned.
11. Connect the RS-485 bus
Note: Do not make connections to the RS-
485 bus while it is connected to an operating
MoniTrace 200N control and monitoring unit.
Damage and/or alarms could result.
The RS-485 bus allows units with unique
addresses to be connected together along a
common bus. To add a new unit to the network,
simply connect the RS-485 bus from the last
unit to the new one, or insert the new unit
between two existing units on the bus. The
order in which units are attached to the RS-485
bus does not matter. There are just two con-
straints on the RS-485 network:
• Each RMM2 must be assigned a unique
address
• The RS-485 bus must be a continuous string
from the MoniTrace 200N to the last RMM2 in
the system.
Note: The RS-485 bus operates at 5 V, and
equipment connected to it could be damaged
by exposure to higher voltages. Take precau-
tions to avoid exposing the RS-485 wiring to
discharge of static electricity or other sources
of high voltage potential; in particular, avoid
contact with the power supply wiring.
7
12. Energize all RMM2s in the network.
Confirm that the RS-485 network is complete
(all RMM2 units and the Moni200N are con-
nected to the RS-485 bus), that the power to
each unit has been turned on, and that at least
one RTD is properly connected to one of the
RTD inputs.
The RMM2 has two sets of terminals for con-
nections to the RS-485 bus. One terminal block
allows the RMM2 to connect to the RS-485 bus,
the second allows a continuation of the bus
to other RMM2 units on the network. Observe
polarity, which is indicated on the RMM2.
Connect the incoming RS-485 bus to the set
of terminals marked “IN”, observing the polar-
ity noted on the cover of the RMM2; use the
terminal marked “S” for the shield of the RS-485
cable. Connect the continuation
of the RS-485 bus to the set of terminals
marked “OUT” in the same manner (not
required for the last RMM2 in the network).
Important: Do not connect the shield of the
RS-485 cables to the enclosureʼs grounding
terminal. Connect the shield only to the RMM2
terminals provided. To avoid the potential
for spurious ground loops, the RS-485 cable
shield should be connected to ground only in
the Moni200N unit. For the last RMM2 in the
network, terminate the RS-485 bus by removing
the shorting block on jumper location J17 from
2–3 and placing it across pins 1–2.

RMM2 units are monitored by a central
Moni200N control and monitoring unit. Its
system software enables you to trigger the
Moni200N to recognize changes to the RMM2
and RTD configuration. Until this software is
run, the Moni200N will not monitor new RMM2s
or RTD.

15. Setting up circuits and assigning
sensors to a circuit.
The assignation of the sensor to a specific
circuit is key to good operation! The MoniTrace
200N system allows one or more RTDs to be
assigned to each circuit. The setup is done via
the user interface software of the MoniTrace
200N controller. Pipe sensors are usually spe-
cific to one particular circuit; ambient sensors
may be assigned to multiple circuits. Sensors
can be used to monitor and/or to control tem-
peratures of individual circuits.
For further information on the structure and
capabilities of the system, refer to the Moni-
Trace 200N System Design Guide (H56583).
Note: Before setting up any circuits in the
system,refer to the MoniTrace 200N Circuit
Definition Worksheet in section E of the Moni-
Trace 200N System Design Guide (H56583).
13. Initializing or updating the MoniTrace
Network
The first time the MoniTrace 200N is energized,
it automatically searches for all connected
Devices (RMMs, RMCs and RTD temperature
sensors). The MoniTrace creates and maintains
an internal list of the hardware it finds. This
function can also be initiated manually and is
required after adding more RMMs or sensors to
an existing system. The “update network” func-
tion must be used prior of the first time use and
after each change to an excisting system before
changes become effective (as well addition as
removal of system components). Refer to the
MoniTrace 200N operating manual (H56583) for
the details concerning these function.
14. If necessary due to problems or ques-
tions, check function of individual mod-
ules.
• Verify that a RMM2 is functioning by confirm-
ing that the run LED ( 6 ) is blinking and the
communications LEDs are flashing
• Verify that the voltage selector jumpers are
set to the appropriate range.
• Check all connections.
• Confirm that the RMM2 network does not
have any duplicate RS-485 addresses.
