3. Installation
3.1 Environment temperature
Ambient temperature range: -5℃~ 55℃. When the ambient
temperature exceeds 55℃for a long time, it is best to choose a place
with good ventilation.
3.2 Installation occasion
◆No corrosion, flammable and explosive gas and liquid places.
◆Secure vibration-free areas.
◆This product is designed for installation of environmental II
standard, pollution level 2 applications.
3.3 Installation method
The product shall be installed horizontally on the back panel of the
electric cabinet, and the distance between the product and the
equipment or cabinet wall above and below shall be no less than 20cm.
Installation in other directions is not conducive to the product itself heat,
and the product under the heat must not have equipment.
Install and fix with DIN slot
DIN slot of 35mm width can be used for installation under low vibration
environment. Open the DIN clasp at the bottom of the module and clip
the bottom of the module on the DIN guide rail; The rotating module is
close to the DIN guide rail and close the DIN clasp. Carefully check
whether the DIN clasp on the module is tightly fixed with the DIN guide
rail.
Install and fix with screws
In case of large vibration, screws must be used to fix the module. M3
can be used to fix the module on the back plate.
The overall size and mounting hole size of this module are shown in
the following. Figure.
3.4 Cable connection and specification
When wiring products, it is recommended to use multiple copper wires
and prefabricate insulated terminals to ensure the quality of wiring. The
recommended cross sectional area and type of wire are shown in the
following table.

For security (to prevent electric shock and fire accident), and reduce
the noise, the module of grounding terminal shall be in strict
accordance with the national electrical code requirements, grounding
resistance should be less than 100 Ω. When more than one module
is grounded, single point grounding should be adopted. The ground

4.2 User connection mode
5 things to pay attention to when wiring:
①The thermocouple (thermal resistance) signal is recommended to be
accessed through the shielded cable (connection cable). Cables
should be kept away from power lines or other wires that may cause
electromagnetic interference. Using long cables (connecting cables) is
susceptible to noise interference. It is recommended to use cables less
than 100 meters in length (connecting cables). The cable (connecting
cable) has impedance, which will introduce measurement error. The
characteristic adjustment can solve this problem.
②The thermal resistance must be connected by a three-wire system.
③It is recommended that the positive and negative terminals of the
channel will not be used L+, L- short connection, in order to prevent the
channel will detect the wrong data.
④If there is too much electrical interference, please connect the
shielding line (the compensation cable shielding end of thermocouple,
the cable shielding end of the thermal resistance connection, the
shielding end of the 485 communication line) with the thermostat
grounding end PG.
⑤The thermostat grounding PGND should be good grounding.

6. BFM
The module USES Modbus to exchange temperature data and other
information with the main module through BFM. A cache of read and
write attributes can be read and written using the MODBUS directive.
MODBUS supports 01, 03, 05, 06 and 16 functions. 01, 05 function
code to the bit register operation, 03, 06, 16 function code to the
integer register operation, if read reserved unit, will get 0 value. With
MODBUS protocol, up to 100 BFM units can be read and written at one
time.
Note: MTCW series thermostat support MTC series thermostat BFM

7. CT input
7.1 Functional specifications
1.There are two kinds of measured currents, which are set according
to "CT action".
①general current measurement (clamp table mode) occasions.

5
Detect current value: update the current when output. ON;Update time:
set the "detection current cycle".
②heater broken line detection occasions.
Detect current value: "current when output is ON" .
update current when output is ON.
"Output current when OFF" updates the current when output is OFF.
Update time: fixed at 100ms.
2.The measured current range can be changed according to "CT turn"
and "CT wire crossing times".
3.Alarm can be set by "broken wire detection", "over current detection"
and "short circuit detection".

8. Instructions for use of MTCW-16-NN
1.MTCW-16-NN has no output control. If temperature control is needed,
it is necessary to cooperate with magmet's remote IO (remote IO model:
MEVW-1616T).
2.Connect A1 and B1 of MTCW-16-NN with A0 and B0 of mevw-1616t
through cables respectively.Communication mode: RS485,
communication protocol: MODBUS
3.Because the default communication parameters are the same, so the
connection can automatically communicate.
4.MTCW-16NN can be controlled by BFM area or temperature control
assistant.
9. Common problems and solutions
When the module does not work properly, please check in turn:
(1) the connection of the power line and the condition of the relevant
switches and protection appliances, so as to ensure the reliable power
supply of the module.
(2) whether the wiring of user terminals is firm.
(3) check whether the 24Vdc power supply is overloaded.
(4) check the application program to ensure that the correct operation
method and parameter range are selected in the application. Special
attention should be paid to the BFM area with special operation timing.
If you still cannot work after the above check, please refer to the
following table.

machine code is the only basis to judge the warranty period. The
equipment without machine code shall be treated as overinsured.
4. Even within the warranty period, a certain maintenance fee will be
charged if:
(1)Failure to operate according to the user's manual;
(2)Machine damage caused by fire, flood, abnormal voltage, etc.
(3)Damage caused when a programmable controller is used for
unusual functions.
(4)Self-disassembly programmable controller
5. The service fee shall be calculated according to the actual cost. If
there is another contract, the contract shall take precedence.
