Explosion-proof telephone connecting relay mTCR
1
Description
The telephone connecting relay type
mTCR is used as a fixed device in
areas that may be at risk due to
explosive gas or dust atmospheres
and which require devices of device
groups II and III of the categories
2G and 2D.
The designated position of normal
use is not mandatory.
The telephone connecting relay type
mTCR is implemented in the follo-
wing ignition protection classes:
Ex e ib mb IIC T4 Gb
Ex tb IIIC T1 35°C Db
IP66
Temperature range
-40°C Ta +70°C
The telephone connecting relay type
mTCR is intended for connection to
analogue telephone networks. It
can be simply installed parallel to a
telephone.
The telephone connecting relay
serves for call signalling through
providing potential-free switching
contacts for the connection of
signalling devices. This means for
example that up to two external
devices (e.g. a horn and a flash
light) can be switched on via call
signal. The call break bypass can
be individually adjusted for one of
the connected devices.
The installation regulations in
accordance with IEC/EN 60079-1 4
as well as the respective national
installation regulations must always
be taken into consideration.
Device strutcture
The telephone connecting relay type
mTCR has an unpainted housing
made of electrostatically conductive
compressed material.
The housing consists of a box-
shaped lower part for receiving the
electronics module. The electronics
module is firmly cast into the lower
part of the housing and cannot be
exchanged.
The cover is pressed onto the lower
part of the housing using four
screws, with a circumferential seal
positioned in between. This forms
the non-intrinsically-safe connection
compartment
.
Intrinsically safe DIP switches
An intrinsically safe 4-pole sliding
switch extends out from the casting
within the device (see device over-
view) for pre-setting the desired
mode of operation.
Designation Type Article no.

NOTE:
Excessive tightening compromises
the protection class.
The following is to be considered
when assembling the sealing plug:
1 . Only the sealing plug belonging to
the cable gland (5) may be used.
2. The head side of the sealing plug
must be on the outside (5).
3. The sealing plug (5) is to be
pushed into the cable gland as
far as it will go.
Assembly and installation
Loosen the cover screws (2)and
remove the cover (1)(see device
overview). Insert the lower part into
the opening (3)using four 4 mm
screws with a head diameter of 6
mm to 7 mm and fasten to the wall
or ceiling or onto a plate. If the head
diameter of the screws is too small,
suitable washers of6 mm to 7 mm in
diameter are to be used in addition.
Lead the connection lines through the
screwed cable connectors (KLE) (4)
and connect them to terminals in
accordance with connection diagram.
For the pre-installed cable glands,
only lines are to be used which
have a sheathing diameter Ø of 5.5
mm to 1 3 mm, since otherwise the
IP66 housing protection class is not
ensured.
The tightening torque of these
screwed cable connectors is 3.5 Nm.
The tightening torque of the cover
screws is 1 .2 Nm.

Sliding switch 4 = OFF => contact follows the call signal
Sliding switch 4 = ON => contact closes for approx. 1 .5 seconds
Function of relay contact 2 (terminals 4 and 6)adjustable
by means of sliding switches.
The contact always follows the call signal. After the call signal, i.e. in the call
break that follows, the contact remains closed for the duration according to
the following setting (call break bypass).
1 = ON => call break bypass approx. 1 second
2 = ON => call break bypass approx. 2 seconds
3 = ON => call break bypass approx. 3 seconds
1 to 3 = OFF => call break bypass approx. 9 seconds
Combinations are possible:

Note:
The smooth functioning in the case of a “double call”, i.e. two short call signals one behind the other, cannot
be guaranteed given the abundance of double call signals worldwide. It is the operator’s responsibilityto test
the function on his system in these cases.

Warnings and safety instructions
This device is an explosion-proof telephone connecting relay specially for operation in a hazardous industrial
environment. The following warnings and safety instructions are to be considered:
1 . The device serves for call signalling at analogue telephone connections through providing potential-
free switching contacts for connecting signalling devices. It is not intended for use in safety-related
applications.
2. The device is constructed in protection class II and may only be connected and operated at the
prescribed voltage. A correct connection is to be ensured. The connection line is to be installed in such a
way that there is no risk of stumbling.
3. The device may only be operated under the ambient conditions indicated (see chapter “description”).
Adverse ambient conditions, such as too high or too low an ambient temperature, are not permissible
since these encourage the failure of electronic components.
4. It is to be ensured that the device, the connection cable etc. are not damaged. If damaged, operating the
device is not permissible.
5. When operating the device, the legal and commercial regulations, the accident prevention regulations and
the electrical codes are to be taken into consideration.
6. In the case of repairs, only original spare parts are permissible, which must be exchanged in a technically
correct manner. Other replacement parts may lead to damage and to the warranty expiring.
7. The device must be de-energised for it to be opened.
8. After switching off, wait 5 minutes before opening.
9. When open, no dust may get into the device.
1 0. The cover seal necessary for the tightness of the housing as well as the collar at the lower part of the
housing may not be damaged during assembly and disassembly.
1 1 . When reconditioning the equipment for use in dust, the reconditioned parts should undergo another
routine check test.
1 2. Changes to the product which serve for technical advancement may be made without being announced
beforehand.
1 3. If using a 4 core installation cable (NYM- J4x 1 ,5 mm2) and the 5 A load each of both relays at an environ-
mental temperature of +70 °C a temperature of +74 °C will be achieved at the cable inlet.
It has to be made sure, that a suitable installation cable will be chosen.
1 4. The manufacturer assumes no liability for the connection being correct!
If the aforementioned points are not adhered to, the explosion protection of the device is no longer ensured
and the device then puts the life of the operator in danger and can cause an explosive atmosphere to be
ignited.
1 5. The connection and the installation of the device have to be carried out by an instructed specialist in
accordance with the prescribed installation regulations and taking the indicated ignition protection class
into consideration.
