MACX MCR-EX-T-UI-UP...
Data sheet
1Description
The configurable and programmable MACX
MCR-EX-T-UI-UP... temperature transducer is used for the
intrinsically safe (Ex i) operation of all standard temperature
sensors (RTDs and thermocouples), voltage signals, re-
mote resistance-type sensors and potentiometers. The tem-
perature input signals are output in a linearized format at the
output. In addition to an analog current and voltage output,
the module also has a switching output. The power supply
has been designed as a wide range power supply.
The devices can be installed in zone 2 in the protection type
“n” (EN 60079-15).
The temperature transducer can be configured with the
standard configuration (see example: “Order key” on
page 6) or order-specific according to the order key and is
delivered calibrated and ready for operation. Possible set-
tings for the modules configured according to the order
(MACX MCR...-C) can be found in the order key on page
page 6.
The set configuration is shown on the label on the side of the
housing.
Features such as sensor type, connection method, measur-
ing range, measuring unit, filter, alarm signal and output
range can be configured using the IFS-CONF software and
a device-specific DTM (Device Type Manager).
Features
– Input for all standard temperature sensors (RTDs and
thermocouples), voltage signals, remote resistance-
type sensors and potentiometers.
– With intrinsically safe inputs [Ex ia] IIC
– Current and voltage output
– Switching output (1 PDT relay)
– Configuration via software (FDT/DTM) or operator inter-
face (IFS-OP-UNIT)
– Up to SIL 2 according to EN 61508 on output 4 ... 20 mA
– 3-way electrical isolation
– Installation in zone 2 permitted
– Wide range power supply 19.2 ... 253 V AC/DC
– With screw or spring-cage connection

8.12 Monitoring function
The temperature transducer is equipped with monitoring
functions for the input and output range.
Input monitoring function
The input monitoring function for line break and short circuit
refers to the sensor connected to the input. When an error is
detected, the output signal is set to the configured error
value. In the case of RTD sensors and resistance-type sen-
sors, short-circuit failures are detected resistance values <
1 .
Short circuits of thermocouples and mV sources cannot be
detected, since 0 V can be a valid signal.
On RTD sensors, resistance-type sensors and potentiome-
ters, a line break is detected when the current flow through
the sensor is faulty.
As soon as the fault has been eliminated, the temperature
transducer continues to perform its normal functions. (see
“LED status indicators” on page 22, Line faults)
Output monitoring function
The current output can be monitored for line breaks and
maximum load. This is activated via the configuration. In
safety-related applications (SIL = ON), the output monitor-
ing is always active. The voltage output is not monitored. As
soon as the fault has been eliminated, the temperature
transducer continues to perform its normal functions. (see
“LED status indicators” on page 22, Line faults)
8.13 Operating modes
8.13.1 SIL ON/SIL OFF
The temperature transducer can either be operated in SIL
ON or SIL OFF. The standard configuration is SIL ON with
DIP switch S1 set to the OFF position. With the order config-
uration, customer-specific configurations can be selected in
the order key (see “Order key” on page 6).
8.13.2 Service mode
Service mode can be selected at any time via the
IFS-OP-UNIT operator interface and the configuration soft-
ware, e.g., IFS-CONF or via DIP switch S1.
If settings are changed during service mode and service
mode is then exited, the temperature transducer performs a
warm start in order to apply the newly set values. If no
changes are made, the transducer starts up in normal mea-
suring mode without a warm start. The switching output
switches according to its configuration.
In service mode, it is also possible to simulate the output sig-
nal independently of the input signal (force). In this case, in
safety-related applications the safety function of the device
is deactivated and the initial value for the analog output sig-
nal is 2 mA, which allows subsequent devices to detect the
deviation from normal operation as a result of the measured
value being underrange.
During service mode, the switching output is deactivated
and remains in its idle position.
9Configuration
Figure 7 Position of the DIP switch and buttons
If the configuration is modified using the
IFS-OP-UNIT operator interface and PC-based
software (e.g., IFS-CONF) or via DIP switch, the
changes made must always be checked again
and released before transfer to the temperature
transducer.
After the transfer, the new data in the temperature
transducer is applied by means of activation and
a warm start.
WARNING: Explosion hazard
When configuring in zone 2, the PC used must be
approved for use in zone 2.
When a DIP switch from S1-2 ... S1-8 (ON) is
switched on, the device is switched to service
mode. The red ERR LED flashes (1.2 Hz) and a
diagnostic I/O fault is displayed in the start
screen.

Appendix
A1 Safety-related applications (SIL 2)
Valid hardware and firmware versions
SIL regulations apply to the following modules:
The safety-related temperature transducers listed above
from the MACX MCR(-EX)-T-... series have been evaluated
by exida Certification S.A. via a Full Assessment in accor-
dance with IEC 61508 Ed.1.0 to SIL 2.
Certificate number: Phoenix Contact 100134C P0019
C001.
A1.1 Safety function and safety requirements
The safety-related measuring transducers are used for the
acquisition of a sensor signal (RTD, TC sensors, resistance-
type sensors, mV sources), that is converted into a scaled
signal and from which a standardized “life zero” current sig-
nal is generated. The entire conversion is continuously mon-
itored to a maximum transmission error of 5%. In the event
of greater deviations, the device switches to the safe state.
The safe state is an output signal of either < 3.6 mA or > 21
mA.
With the REL versions, an additional signal is generated,
which is compared with up to two specified switching thresh-
olds. When the first threshold is reached, the safety relay is
switched on without confirmation contact and when the sec-
ond threshold is reached, it is switched off. Depending on
the application, the safety for the switching output is imple-
mented by either the series or parallel connection of relays
2 and 3, a fuse connected in series, and by monitoring the
calculated switching value. In the event of deviations of
more than 5%, the device switches to the safe state. The
safe state in this case is an uncontrolled relay.
The hardware is also continuously monitored. If an internal
failure is detected, the measuring transducer also switches
to the safe state (current output < 3.6 mA or > 21 mA or un-
controlled relay).
The transition to the safe state always takes place within the
internal failure detection time of 50 s.
The measuring transducer is released (restarted) by switch-
ing off the supply voltage and switching it back on again, by
resetting the transducer via the serial interface, or by activat-
ing the “Restart” option during configuration. The integrated
startup tests are then performed. If the error is still present,
it will be detected during these tests. If it is still present, the
measuring transducer switches back to the safe state.
In addition to the safety functions, there are also monitoring
functions for the input and the current output.
Evaluation
Failures which are detected in the measuring transducer
and to which the transducer responds by switching to the
safe state are safe failures (λs).
Failures where the measuring transducer does not follow a
change of input signal or generates an output signal that de-
viates from the intended value by more than ±5%, are eval-
uated as dangerous failures (λd).
Both safe (λs) and dangerous (λd) failures can be detected
by diagnostic measures. Detected dangerous failures (λdd)
are handled in the same way as safe failures.
The monitoring functions refer to events whose cause is
detected and reported outside of the device.
NOTE: Only those devices with SIL designa-
tion and device firmware with revision 0.92 or
higher are certified for SIL 2.

Summary:
Together with the actual signal transmission, continuous
checks and diagnostic functions are performed in the mea-
suring transducers in order to detect faulty behavior.
The internal failure monitoring time (diagnostics test in-
terval) is the time taken to carry out and repeat these tests in
full. Random hardware faults are detected during this time.
The internal failure monitoring time is 50 seconds.

The calculation is performed assuming a checking interval
(TPROOF) of 1 year and a repair time (MTTR) of 24 hours, a
test coverage (CPT) of 95% and a life time (LT) of 10 years.
On the basis of the value determined for the average proba-
bility of failure PFDavg, the checking interval can be in-
creased to up to 5 years.
The values are valid under the following conditions:
– The failure rates of the components used remain con-
stant throughout the period of use.
– The propagation of failures by the device in the system
is not taken into consideration.
– The repair time (replacement) is 24 hours.
– The failure rates of the external power supply unit are
not taken into consideration.
– The average temperature at which the device is to be
used is 40°C. In this case, normal industrial conditions
are assumed.
– The specified failure rates are based on an average am-
bient temperature of 40°C. For an average ambient
temperature of 60°C, the failure rates must be multiplied
by factor 2.5. Factor 2.5 is based on guide values.

A1.3 Configuring an SIL device
The measuring transducer can be ordered with a standard
configuration (see 1.) or configured for safety-related appli-
cations (see 2.), or can be configured by users themselves
for safety-related applications (see 3.).
1. The measuring transducers are delivered with a stan-
dard configuration for safety-related applications with a
4 - 20 mA output (see order key).
2. Customer-specific pre-configured devices (-C) can be
delivered for both safety-related applications and “nor-
mal” usage. Configuration data is shown on a label.
3. The measuring transducers can also be configured by
users for both safety-related applications and “normal”
usage.
The configuration can be read out and changed at any time
for all devices.

Appendix - Safety-related applications (SIL 2)
en Version 04 PHOENIX CONTACT A-5
Configuring safety-related applications
•Connect the device and PC with the help of the IFS-
USB-PROG-ADAPTER programming adapter (Order
No. 2811271).
•Load the IFS-CONF configuration software (free down-
load at:
www.phoenixcontact.net/catalog).
Further information on the FDT frame application (IFS-
CONF) and the device drivers (DTM) can be found in
the IFS-CONF user manual.
•Read out the active configuration.
•Enter the password in the IFS-CONF in the “PIN” hard-
ware configuration (set to 1111 in the factory).
•Activate/deactivate SIL.
In the case of “SIL ON”, it is also possible to deactivate the
“Restart after failsafe” item here.
This means that in the event of a failure, the measuring
transducer enters the failsafe state according to the safety
functions, but is not restarted.
•Write the modified configuration data to the measuring
transducer.
•Check that the new configuration data in the control
window is correct and confirm with “OK” or “Cancel” if
not correct.
A1.4 Installation and startup
During installation, always observe the package slips
The package slip is supplied with the device. It can also be
downloaded at: www.phoenixcontact.net/catalog.
Lockable housing with IP54 protection is recommended for
the installation of the measuring transducer.
•Check that the configuration of the measuring transduc-
er is correct for the intended application.
•Connect the measuring transducer according to the in-
stallation instructions.
•Make sure that the connected sensor corresponds to
the configuration.
•Check the functionality of the measuring transducer
with connected sensor for correct function.
A calibrated sensor simulator (RTD/TC) and a calibrat-
ed digital multimeter are necessary for checking the
measuring transducer.
•Start up the loop and check that it operates correctly.
A1.5 Notes on operation
Only the green LED (PWR) is on during normal operation.
If a malfunction occurs during operation and the red LED
(ERR) flashes, there is a line fault. The output current of the
measuring transducer is between 2 … 3.6 mA or is higher
than 21.0 mA (in the case of faults in the sensor circuit) or is
0 mA (in the case of a line break in the output circuit).
Check all signal lines. The device will automatically switch
back to normal operation after the fault has been eliminated.
If a fault occurs during operation and the red LED (ERR) is
permanently on, the device has switched to the “safe state”
(output current is less than 2 mA).
Restart the device in order to return it to normal operation.
•If no PC/laptop has been connected, you can also inter-
rupt the power supply.
•Or you can carry out a warm start with the help of the
configuration software (Service > Reset).
The measuring transducer should then return to normal op-
eration. If it does not, the measuring transducer must be re-
placed.
NOTE: Installation, operation, and maintenance
may only be carried out by qualified specialist per-
sonnel.
WARNING: If Functional Safety is activated by a
reconfiguration or changes are made to the active
Functional Safety configuration, the rules under
“Installation and startup” must be observed.
WARNING: Limitations on safety-related ap-
plications
Only 4 ... 20 mA, limited programming of output
current in the event of line faults
(2 mA ≤ IOut ≤ 3.6 mA or IOut ≥ 21 mA)
WARNING: Once new configuration data has
been written, the device performs a warm start
that changes the properties of the device. The fol-
lowing control device must be adapted to these
modifications.
WARNING: The device must be write-protected
to prevent improper use. Write protection is cre-
ated by assigning a password.

A1.6 Recurring checks (SIL 2)
The function of the entire safety loop must be checked reg-
ularly according to EN 61508 and EN 61511. The intervals
for checking are specified by the intervals of each individual
device within the safety loop.
It is the operator's responsibility to select the type of checks
and the checking intervals in the specified time period.
The measuring transducers must be checked at least every
7 years (maximum proof test interval).
Checking must be carried out in such a way that the correct
function of the safety equipment in conjunction with all com-
ponents can be verified.
Possible procedure for recurring checks for discover-
ing dangerous and undetected device failures.
A calibrated sensor simulator (RTD/TC) and a calibrated
digital multimeter are necessary for checking the measuring
transducer.
•Connect the sensor simulator to the input of the mea-
suring transducer using the appropriate connection
method.
•Connect the digital multimeter to the output in current
measuring mode (20 mA range).
The measuring range limits and intermediate values are
specified with the sensor simulator.
The corresponding output values of the measuring trans-
ducer must be checked on the digital multimeter.
Line faults (break and short circuit) are to be simulated on
the input terminals; the configured residual currents are to
be determined on the output.
If the function test result is negative, the measuring trans-
ducer must be taken out of operation and the process put
into a safe state by other measures.
A1.7 Repair
The devices have a long service life, are protected against
malfunctions, and are maintenance-free. However, if a de-
vice should fail, send it back to Phoenix Contact immedi-
ately. The type of malfunction and possible cause must also
be stated.
Please use the original packaging or other suitable safe
packaging when sending devices back for repairs or recali-
bration.

erage of Dan-
gerous Failures
Diagnostic coverage:
DCD = λDD/(λDU + λDD)
HFT Hardware Fault
Tolerance
Hardware Fault Tolerance:
Ability of a function unit to con-
tinue with the execution of a de-
manded function despite exist-
ing failures or deviations
λDRate of Danger-
ous Failures
Proportion of dangerous fail-
ures per hour
λDD Rate of Danger-
ous Detected
Failures
Proportion of detected danger-
ous failures per hour
λDU Rate of Danger-
ous Undetected
Failures
Proportion of undetected dan-
gerous failures per hour
λSRate of Safe
Failures
Proportion of safe failures per
hour
MTBF Mean Time
Between
Failures
Mean time between consecu-
tive failures
PFDavg Average
Probability of
Failure on
Demand
Average probability of failure on
demand of a safety function
PFH Probability of a
Dangerous
Failure per Hour
Probability of failure per hour
for the safety function
SFF Safe Failure
Fraction
Proportion of safe failures: Pro-
portion of failures without the
potential to set the safety-re-
lated system to a dangerous or
impermissible function state
SIL Safety Integrity
Level
International standard IEC
61508 defines four discrete
safety integrity levels (SIL 1 to
4). Each level corresponds to a
probability range for the failure
of a safety function. The higher
the safety integrity level of
safety-related systems, the
lower the probability that the
demanded safety functions will
not be performed.
